We're gonna try an experiment with an integrated ad campaign that allows our audience to interact directly with an advertiser to discuss a product.
Our first attempt at this will involve Renaud Lifestyle Products who have just launched a new air purification system to Hong Kong.
Bit of background on the founder of Renaud Lifestyle Products, Iannique Renaud, a Canadian expat.
His concern with the air quality in Hong Kong and China (he has a young son and is aware that the pollution is a major cause of asthma / airborne diseases) lead him to search for a reasonably priced and effective air purification system. Most of the products he found were massively expensive or did not offer a complete solution.
He was able to obtain exclusivity for Hong Kong for one of the top brands out of the USA - a series of air purifiers that offer complete protection for a reasonable price.
We'll be adding a link to this forum from Renaud's ad later tonight - if you have any questions or comments (or you want to buy an air purifier...) fire away here - Iannique is standing by...
What does " complete protection" mean?
That's a very good question. I believe any brand stating complete protection is simply not stating the true facts.
Using a high quality air purifier will eliminate the harmful bacteria, pollen, and mold found in most homes or offices to about 99%. It is possible to get very significant, although not complete protection from viruses through the use of a high quality air purifier that uses a "True Hepa Filter" (not one of the so called Hepa imitation filters that many brands use to reduce cost)
This is why after months of research we have decided to go with Alen Corporation who on independant tests have outperformed the most expensive brands.
Simply great value!
We just edit this post as of December 1st 2008 to inform all AsiaXpat member that the A375UV has finally arrived to Hong Kong. For people that know air purifiers it has comparable performance to IQ air but is 2 to 3 times cheaper.
What about all the doctors who say that eliminating most of the bacteria and viruses leads to homes that are too clean and may be hindering the immune systems of our children from developing to their full potential?
Is it true that NO purifier can actually effectively remove industrial/transport pollution - the particles are too small???
We don't need mold and bacteria and pollen cleaned out of our air - we need soot and CO2 and whatever else the factories and exhaust pipes spew into our air removed - this is never mentioned in air purifier advertising!!!
How does this product compare with the Swissair? I have a Swissair, and bought it because it was reported to be the only air purifier that could cope with the SARS situation.
How would your machine compare with this machine should SARS break out again?
Busywoman: Here are some links of some unbiased testing sites and you can clearly see that the unit we are offering is on the same playing field as our premium priced counterpart.
Fieter: Yes this is true but the highest concentration of Hong Kong pollutant can be removed but whats great is that the Paralda uses the most advanced Hepa (media) filter which only allows very tiny particles to pass through. In fact they can remove particles down to 0.3 microns.
Over 1 million people die a year from simple household mold and dust. This link might help people have a better understanding of what you are actually breathing.
Axpatguy: Don't really know how to answer your question. Take a microscope - look at your bedsheets, your babies toys and when the sun shines through your window on a hot summer day haven't you ever stopped to think is this stuff harmful to me? Well it is and its not their to build your immune system. Statistics show that close to a million people around the world pass away from the health related illnesses from dust alone - not too sure how many people it saves :)
Well Renaud I will most likely buy one of your purifiers in November when I move due to my wife having some allergy issues.
The sad thing is however that there is still nothing that can protect us against the industrial pollution of China....
I would lik to know more about thei air purifier.Just thinking about byuing one and not sure which one is the best..How much does this one cost????
Price is here
Only air purifiers like the PARALDA that use "True" HEPA Media filters should be used. The filter was developed during World War II by the Atomic Energy Commission and it was designed to remove and capture radioactive dust particles from the air which might escape and present a health hazard to the researchers. The "True" HEPA filter was specifically designed to protect the Human Respiratory System. Even the CDC guidelines (Center for Disease Control and Prevention) for the transmission of tuberculosis (TB) recommend that only HEPA filters with an efficiency of 99.97% tested at 0.3 microns particle size be used.
To answer your next question - WHAT ARE MICRONS?
A micron is a measure of length: "1 micron equals 1 millionth of a meter!". A particle that is 10 microns or less in size is not visible to the naked human eye.
Examples of some common air contaminants and their size in microns:
* Respirable Suspended Particulates (Industrial Pollution) ..(< 10 microns)
* Human Hair ......................................... (70 - 100 microns)
* Human Sneeze ................................. (10 - 100 microns)
* Pet Dander .......................................... (0.5 - 100 microns)
* Pollen ................................................... (5 - 100 microns)
* Spores from Plants .............................. (6 - 100 microns)
* Mold...................................................... (2 - 20 microns)
* Smoke ................................................... (.01 - 1 micron)
* Dust Mite Debris ................................. (0.5 - 50 microns)
* Household Dust ................................. (.05 - 100 microns)
* Skin Flakes ........................................... (0.4 - 10 microns)
* Bacteria................................................. (0.35 - 10 microns)
Its important to know this vital information to understand which air purifiers can effectively eliminate various contaminants.
Hope this helps!
Fieter has a point. Mold, bacteria and pollen have been in the air for millions of years and the human body can deal with them. With pollution, it can't.
Due to growing concern with pollution I went ahead and asked this question to the C.E.O of Alen Corporation -
“Our air purifiers have UV lamps which can take care of bacteria as well as a permanent titanium dioxide filter that in combination with the UV lamps creates a PCO (photo-catalytic oxidation) process that removes certain gases in industrial pollution such as formaldehyde and VOC’s. The base filter for this unit is part HEPA and part activated carbon for light odor control.
We also have another filter that is exclusive to us (patented technology) that uses a special powder that chemically eliminates specific gases in industrial pollution. The powder we are using is optimized for the removal of smoke gases/odors and ammonia. The advantage over carbon filters is since we are not storing the gases they cannot be re-released (which carbon eventually does because it acts as an absorbent) and the amount of carbon to remove these gases is to large to put inside an air purifier whereas we only require a relatively small amount to eliminate these gases.
Since exposure to the risks of exposure to VOC's is not well known we thought it would be appropriate to add additional information about this topic. Sorry its a little long but worth the read!
Organic Gases (Volatile Organic Compounds - VOCs)
Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids inside your home. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products numbering in the thousands. Examples include: paints and lacquers, paint strippers, cleaning supplies, pesticides, building materials and furnishings, office equipment such as copiers and printers, correction fluids and carbonless copy paper, graphics and craft materials including glues and adhesives, permanent markers, and photographic solutions.
Organic chemicals are widely used as ingredients in household products. Paints, varnishes, and wax all contain organic solvents, as do many cleaning, disinfecting, cosmetic, degreasing, and hobby products. Fuels are made up of organic chemicals. All of these products can release organic compounds while you are using them, and, to some degree, when they are stored.
EPA's Total Exposure Assessment Methodology (TEAM) studies found levels of about a dozen common organic pollutants to be 2 to 5 times higher inside homes than outside, regardless of whether the homes were located in rural or highly industrial areas. Additional TEAM studies indicate that while people are using products containing organic chemicals, they can expose themselves and others to very high pollutant levels, and elevated concentrations can persist in the air long after the activity is completed.
Eye, nose, and throat irritation; headaches, loss of coordination, nausea; damage to liver, kidney, and central nervous system. Some organics can cause cancer in animals; some are suspected or known to cause cancer in humans. Key signs or symptoms associated with exposure to VOCs include conjunctival irritation, nose and throat discomfort, headache, allergic skin reaction, dyspnea, declines in serum cholinesterase levels, nausea, emesis, epistaxis, fatigue, dizziness.
The ability of organic chemicals to cause health effects varies greatly from those that are highly toxic, to those with no known health effect. As with other pollutants, the extent and nature of the health effect will depend on many factors including level of exposure and length of time exposed. Eye and respiratory tract irritation, headaches, dizziness, visual disorders, and memory impairment are among the immediate symptoms that some people have experienced soon after exposure to some organics. At present, not much is known about what health effects occur from the levels of organics usually found in homes. Many organic compounds are known to cause cancer in animals; some are suspected of causing, or are known to cause, cancer in humans.
Hi, may i ask a few questions?
(1) how long does it take to replace the filters?
(2) how much do the filters cost ?
(3) Would all particles/waste/dust be hiding inside the machine?
(4) When the machine is turned on in a super quiet room at night, would any sound be heard?
(5) How much electricity would be used per hour? (i.e. watt ?)
(5) Do you have showroom ?
Were excited about the Paralda because its the first air purifier that is completely lead free, ozone safe, and Energy star qualified by the U.S Department of Energy and U.S Environmental Protection Agency.

- Filters cost approximately $480 HKD every 6-9 months. You do have an indicator on the control panel which indicates that your filter should be replaced. UV lights can also be replace after 5 years.
- Yes, you may send us and email at it would be my pleasure to give you directions to our office in Central and show you the air purifier.
There purifiers are great, I can now see the TV again
We are always glad to hear positive feedback and happy to know that you and your families quality of life has just improved
Whats the price if I buy two?
how many do you need for one 3bed flat? presumably one is just not going to cope?
Some AX members have questioned whether an air purifier can help with industrial air pollution.
Fieter quoted “The sad thing is however that there is still nothing that can protect us against the industrial pollution of China....’’
ShrinkingV “”Fieter has a point. Mold, bacteria and pollen have been in the air for millions of years and the human body can deal with them. With pollution, it can't.’”
HERE ARE THE FACTS
As of today September 28th 2008 please link to Hong Kong Environmental Protection
Notice that in 10 out of 14 districts the highest industrial pollutants are Respirable Suspended Particulates. THIS IS EXACTLY WHAT’S DANGEROUS AND WHAT A HEPA AIR PURIFIER REMOVES FROM THE AIR YOU’RE BREATHING
*RSP are the proportion of total suspended particulates of a size smaller than 10 micrometres and they have the ability to penetrate deeply into the lungs. Depending on their source and the existing meteorological conditions, RSP can be made up of a number of different constituents.
A QUALITY AIR PURIFIER WITH A TRUE HEPA MEDIA FILTER WILL REMOVE ALL PARTICLES LARGER THAN 0.3 MICRONS WHICH VIRTUALY COMPLETELY SOLVES THE PROBLEM WITH HONG KONGS HIGHEST POLLUTANT

I would suggest putting one in the rooms you use the most. Especially your bedroom and childrens bedroom because in reality this is where you spend a 1/3 or your day.
If your finances permit one for the living room as well and if your on a tighter budget you may always move one from the bedroom into the living room when you have guests over.
Hi, it's good to see that your company is using one of the logo designs I chose!
I do have a concern about the HEPA filter though, I used to have a Class 10,000 cleanroom production facility using positive pressure and multiple 99.99% HEPA filters throughout for the a/c ventilation, these filters are first and foremost VERY EXPENSIVE (~$3000/each) and they require separate fans above it to "blow" the cool filtered air through which makes lots of noise. You state that your units are max. 60 decibels, which should be fine considering HK's quite noisy environment.
My concern is with so much dust and whatever else in the air, how can your HEPA filter last 6-9 months continuous use? Inside a "normal" household, you would normally open windows to ventilate it (in turn letting dust and other particles inside the home); have clothing, furniture, drapes, etc. which also contribute to even more dust/particles inside the home; and many other dust/particles contributing factors. That would lead to the HEPA filter getting clogged within say 3-4 months.
Effectively, only some of this dust inside the home will get filtered through the unit, and the rest will either be on the floor, furniture, etc. I can't see how a little machine, or even multiple units, will be able to move most of the air inside a room into the unit to be filtered by the HEPA filter. Sorry about my pessimism. But I do applaud your unit for including UV light as a "secondary filter".
Alcheng – before I was involved in the business I asked myself the same question
This is the exact reason we don't recommend using expensive air purifiers which state they can clean an entire house up to 1200 sqft. Logic would suggests its impossible for one unit to clear an entire house because -the airborne particles in your bedroom will not line up single file, out your door through the corridor, past the kitchen into the machine sitting in the corner of the living room.
The reason why we chose this brand of air purifiers is because through independent testing they have out performed the most expensive brands but are less than half the price. Example: By placing one in your bedroom and your daughter’s bedroom you can rest assured that these two rooms will be cleaned airborne particles than by just having one big unit sitting in your living room giving out noise pollution trying to do the whole house.
To answer your main question about being a little pessimist about the 6 - 9 month statement - You are totally correct – the filter will not last 6-9 months if you place it in a barn or home that is severely contaminated by dust musts or other particles. These statistics were taken from testing the units on the average American home. Due to the heavy Hong Kong pollution this could possibly reduce the life of the filter by a month but fortunately filter replacements are only $480 HKD which is far less t than $3000 that you were paying before.
What is the actual capacity of the filter - ie how many lbs of dust can it absorb? How does it decide it is 'full' and needs to be replaced?
Average human loses 3 lbs of skin flakes a year on his bed. Which then feeds the dust mites. Then there is the dog and all the other pollution coming from outside. Can these filters really absorb that much?
I appreciate your concern with dust mites and the dangers they pose in a home. This is why using a hepa filter is necessary because it can eliminate 99% of the dust mites in its area. The length of time your able to use the filter is determined by its size and the dimensions we are using will be effective for 6-9 months. A sensor will alert you when the filter is ready to be changed.
If you would like more information on dust mites/dead skin please read the fact sheet from Ohio State University
Fieter, that's exactly what I was concerned about too. The only way I see it "automatically sense" the filter is full/clogged is either by an electronic timer type system wherein it just "guesstimates" the number of hours the unit has been turned on and is preprogrammed to tell you to change the filter, or by an actual sensor connected to the fan to sense the airflow (if it's being restricted by the filter). Taking the second method into account, the HEPA filter should be properly sealed to the unit somehow (by mechanical means with a sealing gasket) so that the air it is filtering is only going through the filter and not leaking elsewhere.
In my cleanroom's setup, we had an airpressure sensor to actually see the amount of air being pushed around (like a pressurized room) inside the cleanroom. This can only be done through positive pressure. Once the airpressure drops, you know that the filters are getting clogged (not enough airflow through the HEPA filters) and need replacement soon.
Additionally, taking account the polluted air we have in HK, have you ever noticed how much dust still settles on your floor, even right after you have vacuumed AND mopped daily? I just don't see how it can filter 99% of the air inside a room, even with multiple units. There's just dust everywhere - on your furniture, curtains, beds, on yourself, etc.
The only way to truly know the efficiency of an air purifier you would need to purchase a high grade laser particle counter with a price tag of $5000 USD.
Alen Corporation has already independently tested the Paralda - It would simply be false advertising if we were stating these facts and it wasn't true.
To purchase a particle counter visit this link
"The only way to truly know the efficiency of an air purifier you would need to purchase a high grade laser particle counter with a price tag of $5000 USD."
True, but any decent sized HVAC company in HK would have equipment like this as well. What most of us are concerned about is the efficiency of the entire unit, and not just your company's. For anyone to claim their unit can clean 99% of the air in the specified area is just stretching it, no? Plus, you really didn't answer our questions yet.
Please kindly follow these links and you will notice that consumer protection sites, specialists in the business can also support the claims.
The Alen Corporation business module allows consumers to have one of the top home and office air purifiers in the world at an affordable price. If this means that we can't go into each persons home with a particle counter to prove its effectiveness - so be it. We would much rather pass on the savings to the end consumer.
Please read all the links posted throughout this forum and it will be my pleasure to continue this conversation.
Okay, we have been using the new ALEN Paralda air cleaner for 3 weeks now. My wife who has been suffering for some time from both allergies and a low tolerance to the pollution in HK has shown very good improvement while in our house.
In comparison with our previous SHARP Plasmacluster, which seemed to help marginally, this one gets the job done.
As instructed by Renaudlifestyle, we made sure the UV filter was on full time and running on the 2nd speed level full time. It is a very quiet machine and easy to setup and operate. It is a tower shape with a small footprint that is easily placed in any room. We use it in our bedroom and now thinking of buying another for our living room.
While HK does have significant levels of pollution, the inside of your home while thinking is a safe haven actually maybe worse as your aircons are drawing in polluted air and other particles and your home traps them.
I would have to say that even if you dont have an obvious problem that doesnt mean you wont in the future so worth the purchase given the reward of breathing clean air especially during the night time.
Great Product 10/10!
Hello Renaudlifestyle, How would I go about and order one of these purifiers? Thanks
Please send an email to firstname.lastname@example.org with your contact details
- Full Name, Address, Telephone Number
We will reply to you with an invoice with the different payment options. (credit card, cheque or bank transfer). Once payment is completed you will receive your new air purifier within 1 or 2 business days.
Have a great day!
Can you compare the Blueair filters to yours? They claim the Blueair Medical VOC Multigas can remove objscts as small as 0.1 microns. The use carbon and are apparently very good with smoke and VOC's . They are more expensive than the Paralda - I am trying to figure if that is justified.
If you are concerned about VOC's. I would strongly consider using our A375UV Multi Gas Hepa Air Purifier. (also uses carbon activated pellets to absorb VOC's)
Probably the most reliable site that takes independent testing seriously is Air Purifiers America and you may find some great unbiased brand comparisons.
The A375UV in consistantly rated number 1 or 2 in VOC removal and our prices in Hong Kong are even more affordable then in America. The A375UV is definetely superior to the Blueair in removing VOC's'.
To be fair I should mention that the Blueair removed the same amount of particles as the A375UV during independent tests. (which is very good). The Paralda has not been independently tested by the site yet but since it uses the same technology we expect it to test virtually the same.
The A375UV is cheaper so your getting much better overall value and protection by choosing the Alen A375UV. In the end its not a very difficult decision.
Renaud is also selling deluxe BBQ King gas grills at unbelievable prices!
anybody have anything to say about rainbow from rex air, i am contemplating buying one but just a bit worried about the price.
I have heard that the Rex Air is a good vacuum cleaner but over priced.
There are a few pieces of information that are especially important to know about water vacuum cleaners. For one, they use water to trap the dust particles rather than ordinary filters, and this not only improves the quality of air that is coming back out of the vacuum, but as well you can literally see the water getting dirtier as you vacuum, and this can help you to keep track of where the dirtiest places are in your home.
Quick note to let Asia Xpat members know that the A375UV air purifier has finally arrived to Hong Kong and you may send us an email if you have been waiting for this air purifier.
We are still offering free home delivery.
Thanks for posting this link http://www.air-purifiers-america.com/ed_APA_test_results-detail.asp.
hi, is there a store in hk where i can wal in and see the product? i am looking to get another air purifier, now i have a sharp plamacluster
You can drop by the AsiaXPAT office in Central - we've got one running there http://www.asiaxpat.com/mediakit/contact.shtm
Currently we are in discussions with some key retailers to place them in stores but for the time being as distributors for Alen Corporation we have left some samples at the AsiaXpat office in Central for its members to take a look at. We also offer free home deliveries if you do decide to make a purchase.
Edinb: I'm glad you found this link useful.
You might also want to check our website for the chance to win one of our Paralda air purifiers. The lucky draw will take place on January 15th.
Who won the contest?
The contest had over 500 entries and Claire from Mid-Levels ending up winning the Paralda air purifier.
These air purifiers are absolutely excellent. I did my research and finally took the plunge by purchasing 3 units for my home and they do exactly as advertised. Nice crisp, fresh air in the morning and my sons cough disappeared after a week. I have purchased units from fortress before and these Alen units clearly perform much much better. Took me a few minutes to understand the the touch screen but its all good now.
Thanks for the thread Ed....this is product that actually makes a difference without the hefty price tag.
hv anyone heard of Lampe Berger before? aromatheraphy.. it'd useful?
I was persuaded by a friend to buy Lampe Berger before but I found them more to be a gimmick than anything else. Certainly not useful in anyway in terms of purifying the air or boosting anyone's respiratory health!
On the other hand, I recently bought a Paralda for our baby's room and it did clear up my baby's nagging cough. Also his room feels a lot fresher in general. Highly highly recommended.
Can Renaud please comment on the AAF (American Air Filter) HEPA Air Purifer (200 & 400)? I can't find these products listed in any of the product reviews. From the brochure I have they seem to offer comparable performance.
I would like to be able to help you out but unfortunately there is very little information available anywhere about this brand. Most air purification companies will state the same information in the brochure but the major difference comes down to the actual performance under normal living conditions.
I would only trust air purifiers that have been tested with a laser particle counter through an independent source because its simply too easy to state fancy facts in a marketing brochure.
We did research the top 10 brands on the market before deciding on which brand to distribute and we felt that Alen air purifiers were by far the best combination of performance and affordability for office or residential use.
If you have any further questions feel free to let me know.
Posting a link to this discussion on our Beijing forum as this topic has come up there
So, are they available in Beijing?
Please contact the Renaud Lifestyle Products Shanghai office to check out the available delivery cities on the mainland 86-21-61325005 ext 113
I'm just wondering, how are the harmful rays of UV-C lamps that awre located inside air purifiers are blocked? I saw a few prifiers that only had an uv lamp behind front grill and a gilter yet they still have a proyection that if you insert the grill improperly, the unit will not work.Air purifiers are so important in the present day situations.
Have you had any comments from customers that the air purifier cases the air to be dry?
You must be thinking of UV rays from the sun? UV lights in air purifiers are effective 4 to 5 inches from the source which is the UV bulb. The Hepa filter is what catches the airborne particles, bacteria and viruses. The UV light then shines on to the filter from 1.5 inches away and eliminates bacteria or viruses that were caught in the filter.
No never had any comments about dry air. I believe that this would be technically impossible since there is no way for an air purifier to suck up the humidity. Hope you have not been living in Hong Kong too long and are now having side effects from clean air. :)
Considering how humid it is in HK, dry air would be a welcome effect of using one of these heheh....
How is Alen air purifier compared to IQAir? Appreciate some feedback on effectiveness and price. Thank you.
We are looking to purchase an air purifier for the baby's room and the apartment.
I am currently using Alen right now and have used IQ before in the states. I don't see much difference in quality or efficiency but there is a huge difference in price Although I dont have breathing problems but my child does and his cough disappeared within a week which is what I base my feedback on.
I based my decision by reviewing this and can say from a consumer stand point the product comparisons are spot on http://www.air-purifiers-america.com/lc_home_editorsRatings.asp.
Yes, I have an IQ Air as well - is there any difference (apart from the price)?
And I suppose our windows should be kept mainly closed, opened for a couple of hours a day, is that right?
"And I suppose our windows should be kept mainly closed, opened for a couple of hours a day, is that right?"
If you open the windows you're "cleaning" the outside air as well. There's no way your purifier can keep up.
Of course it is recommended to keep the windows shut but we are all human and love the feel of outdoor air once in awhile. I personally feel this is more about prevention then trying to make our home a hospital room so even I occasionally open the windows at home for a short period of time. Axptguy38 is right that the filter will be working overtime if you do open the windows.
The U.S manufacture states that the filter needs to be changed every 6 to 9 months but we are finding that that in Hong Kong under normal use the filter needs changing every 6 months due to much higher pollution levels. If you run any air purifier with the windows open it will significantly reduce the life of the filter. Your indoor/outdoor environment will also impact the life of the filter ex: construction near by, poorly constructed buildings etc...
The filter replacement cost for the Paralda is 480HKD and the A375UV is 580HKD.
By the way we are currently setting up our new Alen site that also has additional useful info & videos.
I recently went to an Ear Nose & Throat specialist because of constant nose bleeds. I expected him to tell me that the rotten Hong Kong air was causing the nose bleeds but to my surprise he diagnosed the problem as being caused by narrow air passages in my nose and the dry air in the apartment.
I asked if I should buy an air pureifier and again to my surprise was told it was the worst thing I could do as the purifier takes moisture out of the air! He recommended buying a humidifier and putting it on my side of the bed at night.
After doing this for a month the nose bleeds have stopped (keep the humidifier on every night).
So......do the air purifiers take the moisture out of the air or not?? Perhaps you can answer this Renaudlifestyle??
My answer to your question is that it is absolutely 100% impossible for an air purifier to take moisture out of the air.
Your doctor could be thinking of an of air conditioner? The technology of an air conditioner is such that it cools the air by taking moisture out. (This is why you can often see water dripping from an air conditioner). You will never see water around an air purifier and the moisture needs to go somewhere to be effectively removed.
I am not expert on air conditioners but i know its a fairly common for certain people to have nose bleeds or dry nasal passages if they sleep with it on.
Just think of an air purifier as a reversed fan that sucks air in through a filter to be blown out clean through the other side. There is no system to remove moisture or the hepa filter would be wet thus making it ineffective.
Thanks for all the clear and researched information above. Having a baby soon, so considering an air purifier. Some questions.
- Does the simultaneous use of dehumidifier affect the efficiency of the air purifier (although sounds ridiculous that I need an air con, air dehumidifier and air purifier)
- Should I also be getting a special water vapour hoover, or is that just overdoing it if I get air purifier as this would get rid of any residual particles from normal hoover.
- If I understand above correctly, it will also get rid of some of the polutants in HK from soot, car pollution, etc?
- I have visited your website, and see that the only difference between Paralda and A375UV is the PCO system. Can you pls help explain your views on when I should choose one vs the other? I guess design is the other reason, as they are about the same size in terms of volume, right?
- What is the delivery time for each of these?
I understand how it seems physically impossible for the air purifier to remove moisture, but I have a situation in HK where it is the air purifier that is 'causing' the dry air. We have through process of elimination with the A/C's off and no purifier on, then the purifier on and the air is noticeably drier feeling.
In my un-scientific google research on this issue I have found a posting where a voice coach has advised a student not to use an air purifier due to the dry air it can cause.
I know it sounds illogical, but there is something happening.
I do appreciate your concern with dry air but I will stick with the statement that it is 100% impossible for the air purifier to cause dry air. It is only fair to the AX readers that you come up with research/facts stating otherwise or this forum post will simply be a rumor mill without any scientific backing. I have done my research and I am throwing a challenge out to you to prove otherwise.
If you are able to find any information we will be the first to back your claim because considering the high humidity levels in HK it would make Alen air purifiers much more attractive to the HK market.
Don't take this the wrong way but until someone comes up with facts lets please squash this topic and consider it case closed.
Not to sounds like a shell, but I agree with Renaudlifestyle. Air purifiers do not dry out the air.
Dehumidifiers don't affect the efficiency of an air purifier and I dont think the use of a "water vacuum cleaner is necessary if your running an air purifer but it wouldn't hurt. .
The way I look at it is you putting your mouth on the floor to breathe it could be quite useful Joking a side scientific research does show that a water vacuum cleaner can be useful for certain particles that do drop to the floor and is much more efficient than a regular vacuum cleaner. I would also prefer not to elaborate further because I have not done enough research on it to give valuable input to the thread.
Here is the difference between the A375UV and Paralda.
The other main difference found in the product description is the Paralda cleans up to 400 sqf and the A375UV up to 800 sqf.
My personal recommendation would be the Paralda for bedrooms because its a quieter unit and you can sleep comfortably with it on the 2nd speed. (it has 4)
The A375UV has a more powerful fan which means a little noisier. i personally put the A375UV in the larger living area and hallway because it can clean out a large area in no time.
Hope this helps.
many txs. I'll get one online.
I have a concern mainly with VOCs as I will be moving into a newly renovated apartment soon. So I need to buy two or three more air purifiers (BTW can I get a bigger discount if I order more than one purifier) I read carbon based filters (which I belive are in the Alen purifiers) can remove VOCs so do these gas particles just get trapped inside the carbon filter or is there a chemical reaction that will make the gases less hazardous. If they are just trapped inside how is that cleaned. Currently I have two sharp air purifiers and one of them I can wash the carbon filter whereas one cannot. I am just curious what happens to the VOCs.
May I submit that having both a Sharp Plasmacluster and the new Alen Paralda, the Paralda wins hands down after using it for the last ten months. For my use it was like night and day and within 3-5 days was noticeable to my wife who suffers badly from pollution, minor allergies and any dampness.
Even for myself, I find having the Paralda in our master bedroom has taken away the dry throat I used to have in the mornings. Not to mention my children have found the same.
While I do agree with the benefit of having a removable, washable filter in the Sharp, it is my belief that it is one of the shortcomings to the ultimate performance of this unit on top of just not getting the job done like the Paralda.
I am definitely going to purchase a few more for the bedrooms and an A375UV for my large living room.
I personally cannot stress enough how important it is for us to breath the cleanest air possible. In Hong Kong, we are all challenged by both pollution and hiding in our homes which only traps bad air and recirculates it!
Having an air cleaner in your home should be considered a must have! Again, even those who do not suffer in an obvious way I believe are just kidding themselves and over time will suffer the same effects.
You are 100% correct the A375UV does have carbon activated pellets and carbon does absorb VOC gases. The problem is that certain people do not dispose of the filters in a timely fashion so these gases can be re-released after a certain period of time if you leave old filters laying around the house. This is another reason why its important to change the filters in your air purifiers. Alen did realize this while they were designing the A375UV so they added a little known feature called Photo-Catalytic Oxidation which converts the gases into harmless elements.
A large contributing factor to poor indoor air quality is the release of VOC’s. VOC’s are organic (carbon based) and are emitted as gases from a variety of products. Also called hydrocarbons, VOC’s vaporize due to sufficiently high vapor pressures.
The common indoor sources of VOC’s are paint, carpeting, copiers/printers, laminated furniture, wood preservatives, paint thinner, glues, permanent markers, cosmetics and certain aerosols and plastics. If there is not sufficient ventilation with the outdoor air and VOC’s are present, the indoor pollution levels can be up to 10 times higher than the outdoor air according to the EPA. And that includes urban area
The A375UV includes UV-PCO (UV Photo Catalytic Oxidation) technology to reduce the levels of VOC’s. The interaction of UV-C light and a permanent titanium dioxide (TiO2) grid serves as a photocatalyst to carry out hydrolysis (ie. to break water into hydrogen and oxygen). As TiO2 is exposed to UV light, it becomes increasingly hydrophilic; thus, it can be used reduce concentrations of airborne pollutants such as volatile organic compounds into harmless elements.
To answer you question about discounts on multiple units yes we do have promotions. Occasionally its in the form of a free filter or a percentage off your total order. Feel free to contact me any time and let me know that we chatted via AX and it will be my pleasure to sort you out or answer your questions in more detail over the phone.
With all the talk about the swine flu shutting down schools all over town I was wondering if air purifiers can reduce the chance of catching it??
I believe any opportunity to better your health is key. If you breath clean air, it will only better your immune system thus bettering your chances. This is just common sense to most but easy to do means easy not to do!
You insure yourself, your car and occupants, why not your family further with such a device. This is my reasoning for owning a few.
Oh yeah, why not buy the best!
"With all the talk about the swine flu shutting down schools all over town I was wondering if air purifiers can reduce the chance of catching it??"
In theory, perhaps by an infinitesimal amount. But in reality you are unlikely to catch it in the house unless someone else is already infected. You'll get it while out and about.
Actually the UV light in Alen air purifiers can eliminate the swine flu virus. The virus would need to go through the unit and come within 3 to 4 inches of the UV light.
By the way we have a few new product videos online for people interested in learning more about the air purifiers.
I am also very glad to hear that our air purifiers have made a difference in people's live and welcome any feedback or questions.
Well I guess you're right but i think its much more protection than an infinitesimal amount " At least we have peace of mind when we are at home. Just hope it doesn't mutate into something more fierce.
So Renaud you are saying keep the UV light on just in case right?
We bought the Paralda back in January. our 3yr old had a permanent cough which only cleared up on vacations, after our xmas break his cough returned yet again. we'd always promised that if the air affected his health we'd leave Hong Kong. but after a bit of googling decided to buy this filter as a last ditch solution. i can honestly say the difference is day and night. he's had one cough since, which i would say is more than fine as kids pick up loads of bugs from each other. i wish i'd done it 3 yrs ago! Pete
Extremely happy to hear that the air purifier has made a significant difference in your child's quality of life. I cant even count how many people have come back to us with similar stories and as a business its very satisfying to know that our products truly make a difference.
We are currently trying to research which pollutant causes this disturbing cough. From our experience its usually in children under 10 years old and the highest percentage would be under 5 because there lungs are still developing at that age.
In recognition of the poisonous air we breath in Hong Kong, I hereby and therefore in the interests of all people in this city raise this thread to the top.
I'm shopping for an air purifier too and have a few questions:
1) Is Alen Corp affiliated with HKXPAT? I noticed you both have the same address at 5/F Yat Fat Building on Des Voeux Rd in Hong Kong.
2) When you say you're "America's # 1 Air Purifier..." What exactly do you mean? Number one is sales? Number one in ratings? Number one in customer satisfaction? Do you information to support this claim?
Please respond. Thanks...I just want to be sure for the sake of comparison. Your products are more expensive than those Whirlpool & Sharp brands at Fortress. Frankly, I've live in the US for 20+ years and have never heard of Alen Corp...
Any information will be very helpful.
Alen is a US company - their China distributor is in Shanghai - they use our office as a mailing address for Hong Kong.
I will leave the people from Alen to respond to the rest of your questions
Very valid question and if we can simply place more info on a banner it could be explained. Alen is the #1 air purifier in performance and affordability - yes they do have supporting testing and reports to validate the claims. If your looking for percentage of market share other brands would definitely be rated higher but we base ours on performance.
I believe in the past we have posted quite a few links pointing to sites that can also validate this position.
- Considered #1 Best Value Air Purifier on the Market
- Voted top Air Purification brand by the only retailer that actually tests the units they sell with a laser particle counter.
For the sake of comparison and performance these 2 links are where you want to start.
We do keep air purifiers on display at the office in Central on Des Voeux Road for AX members to come and see the units in action.
I would also like to thank AsiaXpat for providing such a great platform which allows us to truly have a hands on approach in communicating with members like yourself.
For more information I invite you to view our product videos online.
I would agree completely with the above. #1 overall in performance, price and quality!
I have to be honest, I got sucked in by the marketing on the SHARP Plasma-cluster along with some reviews but all were based on price. I went down the track of the IQ AIR based on what I feel was an over rotation to get something that could not be disputed but price was beyond acceptable.
Going back to the SHARP models, there was NO WAY of guaranteeing if the product actually worked unless you had high end testing equipment and do a before after test.
I was absolutely stuck!
The proof therefore was very simple! When I ran the Alen Paralda there was a noticeable and REAL difference in our health, especially my wife's, who is suffering after a 6 year stay in HK. Dry throat, running nose, cough, all gone in only 3 days.
Further, I am now running Paralda in all of my bedrooms and run a model A375 Multi Gas in my living room which is absolutely excellent.
Again, while stating the obvious that you cannot put a price on you and your families health, may I submit that Alen has designed Air Purifiers which DELIVER what is advertised at a price most affordable!
One small note, the Alen Paralda is the only Energy Star Qualified unit I have seen on the market today. The difference in the premium (which again is not anywhere near what you would think), will pay for itself and one big issue that everyone does not account for is noise. The Paralda is so quiet, you wont even know its on.
I hope this helps everyone with their decision as it took over 2 years and making the wrong decisions to bring me to these conclusions.
I would like Alen air to answer the following question:
I understand that Allen filters compare very well with more expansive IQAir machines. These are American tests that look at dust and pollen - much bigger particles than the carbon based pollution we try to filter out in HKG.
However IQAir states that their machines filter down to 0.003 Microns. This is very important due to the fact that pollution in HKG ( carbon based exhaust emssions etc) is generally of a particle size of 0.01 micron or smaller. Tha average HEPA filter does 0.3 microns - which is fine for pollen and dust but not good enough for HKG pollution.
Renaudlifestyle has claimed in an earlier post that HKG pollution is 0.3 microns or bigger. I do not believe this is correct. There is a lot of evidence that particularly diesel exhaust is very carcinogenic and comes in particle size down to 0.008 micron or less
Does Alen filters filter down to 0.00x micron and smaller like IQ air???? Nowhere in their marketing do they refer to this - which makes me wonder.....
It would be my pleasure to respond to your email in greater detail tomorrow morning and as a father myself appreciate you concern with the above pollutants.
Could you please tell me where we stated that HK pollution is O.3 microns or bigger?
I think most people need to realize that a good air purifier not only has HEPA but other technologies to remove various pollutants. What really sets Alen apart is we offer a multi-filtration technology I think this will answer most of your questions.
The Hong Kong Environmental Protection Department states that the most of the pollutants are 10 microns or smaller = 10 microns. Not 0.0000xxx. Also note that even in other air purifiers its not the HEPA filter that removes gases from our home but the other little known technologies that are incorporated in to a high performance air purifier like IQ or Alen and this is why different models / options are offered.
Alen filtration technologies can be turned on or off depending on what you're trying to achieve.
Our A375UV is best in class and only air purifier out there that can permanently remove a wide range of gases, volatile organic compounds, smoke, ammonia, etc.. Other gas air purifiers typically use carbon, which can be a problem because carbon stores gases which can be released at a later whereas our solution permanently eliminates the gas/odor on contact. Exclusive targeted technology was developed to address specific indoor air pollutants by PhD chemists and patented.
The A375UV includes UV-PCO(UV Photo Catalytic Oxidation) technology to reduce the levels of VOC's. The interaction of UV-C light and a permanent titanium dioxide (TiO2) grid serves as a photocatalyst to carry out hydrolysis (ie.to break water into hydrogen and oxygen). As TiO2 is exposed to UV light, it becomes increasingly hydrophilic; thus, it can be used reduce concentrations of airborne pollutants such as volatile organic compounds into harmless elements. Ya, we pack a lot of technology into our little air purifiers! As a safety feature, the UV-C lights and titanium dioxide grid are located on the inner most section of the A375UV.
UV Light (ultraviolet)
Our UV air purifiers have been tested to eliminate over 96%,
Ultraviolet light kills microorganisms by damaging the DNA. UV radiation disrupts the chemical bonds that hold the atoms of DNA together in the microorganism. If enough of these defects accumulate on a microorganism's DNA its replication is inhibited, thereby rendering it harmless. If the damage is severe enough, the bacteria cannot repair the damage and will die.
Bacteria are single cell microorganisms that exist everywhere. They are often 0.2 to 5 microns in diameter and most do not create an issue for people. But the ones that can present problems are pretty bad problems:
* Staphylococcus aureus are bacteria known to cause "staph" infections.
* Klebsiella pneumonia is a bacteria that can cause pneumonia.
* E Coli is a bacteria that is often associated with food poisoning but it also exists in the air and can affect the respiratory system.
NEW Silver Ion HEPA Filtration (Silver has been around for thousands of year and hopefully one of the answers to reduce swine flu)
The new Silver Ion HEPA filter eliminates up to 99% of bacteria, up to 50% of viruses that cause influenza and 99% of airborne allergens. The Silver Ion HEPA filter is coated with Silver Ion, which is antimicrobial. This keeps germs from developing inside the unit and prevents bacteria from being blown into the air. Silver Ion coatings greatly reduce the presence of fungi and bacteria within five minutes of operation. Through a process of denaturation and oxidation, the structure of the enzyme that produces oxygen gets detached and silver ion particles produce reactive oxygen in the air which works to destroy over 650 types of bacteria. Toxic to viruses and bacteria, silver ion is harmless to humans.
This is the same filter technology as recommended by the US Department of Homeland Security to remove harmful airborne particles in a terrorist threat. Tested at over 1,000% better than the leading ionic air purifier and up to 50% better than leading HEPA type air purifiers by the world's leading independent test.
We have more developments on the way but this should do for now. Thanks for you're question.
What a load of crock. Just open your window for fresh air. I mean humans have been able to survive for millions of years just breathing in fresh air (maybe with pollen, dust, who knows) without a HEPA filter, etc.
pizzaman, please deliver some fresh air to my hk home. 3 cubic meter for tonight, thanks
I think you need a bit more than that but I second the sentiment.
It's not the pollen that is the issue!
Thanks for the comment and I am sure glad you weren't my doctor when my son was born and had a lingering cough that if not had cleared up due to external help it could of lead to a chronic medical condition and who knows what else.
For the thousands of parent out there and I am quite sure they simply wont say " Hey we have been living with this for thousands of years and my baby boy/girl is just a number but the human race will always reproduce!"
Feel free to come by our office anytime and it would be my pleasure to talk with you about the hundreds of cases that where an Alen air purifier has made a significant difference in peoples lives.
Since I have been involved within Alen in HK I am still waiting to hear of one case where the client didnt feel a significant difference in the air they breathe.
Thanks for your comment.

just a little off topic...
i wonder how effective (or not) air purifiers would be in a red dust storm that Australia is experiencing now
SYDNEY - A pall of red dust blown in from the Outback clogged the skies over Sydney on Wednesday, diverting international flights, disrupting public transport and prompting a spike in emergency calls from people suffering breathing difficulties.
I guess it's moving north now so things should clear up in a few days.
so is that a yes or a no - not effective?
Yes, the air purifier would be effective in removing dust during this type of storm. Although I should say that the filter life would be drastically reduced due too much higher concentrations.
PizzaAce, now that you have been thawed out after being frozen in time, check to see how fresh your cave air is in HK.
My view is simple, while at some point in time (recently in the last 20 years I believe), we outgrew the world and no longer can adapt to the changes to stay healthy. We need assistance in key areas, Air Purification is not unlike Water Purification. We need constant supply of both everyday.
On a more factual note, try googling 'deaths due to air pollution asia' and see what comes up! #1 is the following, there are thousands of factual reports available to you, please educate yourself!
Indoor Air Pollution - Silent Killer of Women
Over 1.5 million females die prematurely every year by inhaling poisonous fumes (by Nilay Ranjan)
Over 1.5 million females die prematurely every year by inhaling poisonous fumes as they cook or heat their homes with these organic fuels but catch little attention from governments, policy experts, scientists and medical experts.
Good news for the possible massive flu season. Our new Silver Ion Hepa filters available for all models will be arriving mid-September from the U.S
The new Silver Ion HEPA filter eliminates up to 98% of bacteria, up to 50% of viruses that cause influenza and 99% of airborne allergens. The Silver Ion HEPA filter is coated with Silver Ion, which is antimicrobial. This keeps germs from developing inside the unit and prevents bacteria from being blown into the air.

To see a diagram on how it works follow this link:
On a stinky note we are pleased to announce that we have finally shipped Alen's patented odor spray from the U.S
We've smelt all that mysterious stench coming from the backseat - not sure it is a forgotten milk container or your gym bag, but whatever it is, it's revolting. A few squirts and those little stinky molecules are gone and your car is smelling good enough to valet again.
The chemists that engineered this spray had no concept that cars could stink, til they carpooled with one of the sales guys. Their findings are what sets Odor4 apart from other odor removal products — its patented process. Odors are attacked in two ways. First, at the molecular level we neutralize the odor by converting it into an odorless particle. Second, through encapsulation the odor is surrounded and sealed off. This means that nearly instantly the odor is gone forever and you are left with a fresh scent.
This formulation has been used by the pros in hotels, car rental agencies and car dealerships to remove odors from fabrics, carpeting and upholstery; the very things that hold in odors and we are now making it available for in-home use.
hi...would it be we will dependent on this purifier since it will provide th fresh air? I'm worried our nose become more sensitive since u have used to the fresh air? If one day u travel to those polluted country can u stick to that environment?
I am interested to buy, but was wondering whether we need to close the windows when the Alen air filter is running?
Its is recommended to keep the windows closed most of the time because the second you open the windows is when airborne particles enter your home. Indoor air pollotion can be 7-10 times worst than outdoor pollution.
Although if you just painted your home VOC gas' would be a concern so I would suggest opening your windows far a period of time and also running our A375UV multi-gas air purifier once you decide to spend extended periods ot time in those rooms.
On a personal note I feel there is nothing wrong with opening the windows and letting our home air out once in awhile. Once you turn the air purifiers on full speed you will achieve apprx 4 air changes per hour within its recommended square footage so the particles let in would be filtered quickly.
The one disadvantage of running your air purifier with the windows open is that you would need to replace your filters more often so I suggest turning off the units when plan on opening the windows.
HI Peng Hong 647,
As someone in a previous post said our bodies have been adjusting to certain natural contaminants for 1000's of years but our bodies aren't built to adjust to the industrial pollution ex: Suspended coal particulate being blown over from the 200,000 + factories accross the border.
A smoker can enhale a pack of cigarettes a day without having that burning sensation in his throat yet he can be invisibly unhealthy. A non smoker decides to try a cigarette with him and coughs his lungs out but is the most healthy of the two and lives an extra 10 years.
Do you keep your purifier on the entire day or only when you are in the room?
In Hong Kong I keep the air purifiers on the entire day where my children spend the most time because obviously they are my biggest concern when living in this type of environment. I do have friends without children and they only turn them on when they get home and still feel a noticeable difference.
The units have 4 speeds so I also suggest adjusting them to a lower speed when your at work - higher speed to clean the house when you arrive and then to the 2nd speed during sleeping hours.
The units are built to run 24/7 and they are also Energy Star Qualified which means they run on pennies a day.
-Existing medical conditions like allergies, asthma, etc: All Day
-You have children: All Day
-Healthy person just concerned about pollutants: All day or just when your at home
-Office space: All day but adjust to a lower speed after hours.
I am off to my sons Kindergarten class right now but will be available for further questions this afternoon.
Thank you. Any noticeable difference in electricity bill when running the air purifier on 24/7?
It has the Energy Star seal of approval which basically means energy efficient and environmentally friendly which will cost you 0.5 HKD per day X 30 days = 15hkd per unit if you run it 24/7.
I have Paralda's in each of our bedrooms that are always used (3) one Paralda in my home office and one A375UV's in each of my living areas. That's 6 units in total as I have a quite a large home.
During the hot summer days or anytime I feel the pollution is worse than normal my windows especially in the bedrooms and my home office are closed and A/C on low so I will have each of my AP's running on low as well.
For rooms which receive outdoor air during the day or during the fall-winter-spring months when temps are tollerable, I only run the AP's when we as a family are home and before dinner clear both the family room and dining room with my 375's, takes 30 mins on auto setting. While having dinner, my bedrooms are being purified until we go to bed on speed 2-3 and during the night on speed 1.
If for any reason the children are at home playing we will simply set the AP's on in rooms which they are using. We have been using the Paralda since it was released in HK and have since fit up the whole house and have never looked back.
In essense we have set our own in-house CLEAN AIR POLICY. It is now a ritual and not only has it made a big difference to our family, but even friends who spend 2-3 hours at our home have commented on it.
My wifes dry throat, coughing and nasal problems have gone. My 8 year old who has been in HK for 6 years who was finally showing signs of the same is now not suffering, preventatively it was easy to do the rest of the house.
We pay big bucks for clean water, we pay the same for high quality food, why would we deny ourselves of clean air!!!
I read on the www.air-purifiers-america.com website that many customers complained about the UV lights failing within weeks or months of purchase. Is this UV light issue covered by the lifetime warranty?
furthermore - is the silver HEPA filter (marketet as an add-on Flu Prevention Filter in the US) available in HK, too?
Yes, everything is covered by the lifetime warranty and the Silver Hepa filter for flu prevention is available in Hong Kong. Alen did have issues with a small number of 1st generation units in the U.S late 2008 / early 2009. Alen is already on the 3rd generation of Paralda's and everything is in tip top shape backed by a lifetime warranty and a 30 day return policy.
Lets also not forget that the only website that tests units with a laser particle counter has given Alen a #1 rating over its premium priced competitors and also has the highest 5 star customer feedback out of all the brands they carry.
Thanks for your questions.
I dont need this to tell me the air pollution is low medium or high... when its high I have a constant hack... but FYI http://www.epd-asg.gov.hk/
forget the government API .. that's based on outdated 1980 ideas about air quality.
if you want to know what's really happening, and have a useful benchmark - the W.H.O. Air Quality Guidelines - to assess it against you need this:
Even though I really dislike the way AsiaXpat deals with questions that are considered unfavourable to their advertiser Alen/Renaud (I got posts deleted and threats of account suspension), I will give credit to the Alen Product when it's due - and here credit certainly IS due:
yesterday, far away from city smog on Lantau Island:
outdoors: 230,000 particles per litre of air (p/l) (and that was a "clear air" day, a bad day sees a million and more)
indoors: approx. 160,000 p/l
in a room with an Alen Paralda, speed 3 for 1 hour before the test: 10,000 to 11,000 p/l
directly at the air outlet of the Alen Paralda: 800-1,400 p/l
(particle size measured > 0.3 micron)
to give these values some meaning: more than 105,000 p/l are considered a health risk by the W.H.O., anything below 60,000 p/l is considered good air quality, high up in the Swiss Alps you will find 2,000 p/l ...
The Paralda did remove up to 99,5% of the particles, and reduced the room particle load by 93% within 1 hour. (120 sq/ft room)
The only downside is: it's quite noisy! But if you run it for 1-2h before going to bed on high and on 1 whilst sleeping it's no problem at all.
So - the verdict is: Alen's Paralda does what it says on the tin.
Very good filtration at an exceptionally good price.
If you want more protection (including particles below 0.3 micron) you'll have to fork out 3-4 times the money for an IQ-Air.
flyboyHK, great post! Which Particle Counter are you using? I have noticed a considerable difference in my home since adding both Paralda's and A375UV's from ALEN but would like to quantify the benefits such as you.
The counter used was a swiss made "Particle Scan Pro", a 6-channel laser particle counter with a detection range of 0.3 to 30 microns.
FlyboyHK - The Particle Scan Pro is an extremely accurate particle counter and I appreciate your testimonial on the effectiveness that our air purifier had in a real life environment.
Its not everyday that customers have access to these kinds of tools and this clearly demonstrates why Alen is considered #1 Performance, affordability and ease of use.
You certainly cant get a better unbiased testimonial than that!
My son and I use the Paralda on speed 2 at night but give the room a good clean on 3 or 4 for a couple hours before going to bed.

This is not good news!
Babies in the womb are more susceptible than their mothers to DNA damage from air pollution, despite the added protection that the placenta is thought to provide in filtering out toxins.
In a study of newborns and their mothers in New York City, scientists found that developing babies had accumulated a relatively high number of genetic mutations, and they linked the mutations to emissions from vehicles and other sources of urban pollution.
The newborns also had more toxins in their bodies from secondhand smoke than their mothers, who were all nonsmokers. The study appears in Environmental Health Perspectives.
The findings “highlight the need to protect pregnant women and especially their children as a sensitive subset of the population,” the researchers conclude.

I just came across your thread, but I see I've missed the promotion.
I'm wondering if you will do another promotion?
That was a 5 day Xmas promotion to show our thanks to all the AX members using Alen.
The discounted prices are on the website with different packages that allows you to save a little more.
The aiir purifiers are working great but I think we need to get a replacement filter because the filter looks dirty as heck. Where can we purchase these?
Sorry double post
I assume that your filter sensor light came on indicating it should be changed right?
All of our products including the filters can be purchased directly online.
Here is the link for the replacement filter page and should you need assistance feel free to contact us at 2115 8201
seems a few of us are keen for another promotion...
Currently we do have a promotion on our whole house packages.
maybe another promotion for CNY ;-). Interested to buy it too.
Yes I'm interested to buy too... have a quick question:
You mentioned four speeds but is there an "auto"? I have the sharp air purifiers which we leave on auto because they can detect the dirty air and turn themselves onto higher power if need be.
How come your air purifier has no auto mode?
@ slammy - the A375UV does have a auto mode, the Paralda does not. But most of the time a look out of the window gives you a good indication of which speed to set it to ...
can someone help me on how to use this?
i got the unit for 2 days now and not satisfied yet, my toddler had terrible cough and difficulty breathing on the first night i had it. I run it in his room for 2 hrs and he slept there, maybe i should have run it the whole day first in the living room.....anyways, it's now in our living room but i still can smell something different - it smells like first time running a heater.
Which setting should i use? do i need to ON the UV and ION sign? the manual doesn't say anything about this button. I set it up in 2nd mode.
I have the peralda. Thanks.
Even though it doesnt seem like it actually seems that your daughter is adjusting for the better to the clean air.Toddlers lungs feel the effects when they change from a dirty environment to a clean environment. There is absolutely no need to worry because once her/his little lungs adjust to the air she will be so much better off. Most of people using Alen will experience a substantial change within 5 to 6 days.
If you are using an air conditioner in her room which drys the air I suggest also purchasing a small humidifier and running all 3 at the same time.
For my baby boy I run the air purifier on the speed 2 during sleeping hours, 4 an hour before bed and 1 when he is not home.
Please read the posts above about UV light, Hepa filters, and the other filtration's. I personally only like to use the Hepa and UV light at home.
I have experienced everything you are going through before but please dont make the mistake of removing a premium quality air purifier from your childs room in Hong Kong because the pollution related health effects are very very serious!
I agree with Uknowwhat...it will take about a week to see some benefit as it likely took quite a long time for the symptoms to develop in the first place.
Your HEPA on the Paralda should take care of most of the needed filtration in your childs room. I turn on the UV when I feel we have flu like symptoms in the house. I turn on the Ionizer only when we suffer from headaches or need extra respiratory relief. Especially with allergies.
I run Paralda's in each of our bedrooms on speed 1 during the day, speed 2 in the common areas if we are home all day and speed 1 at night. If I am away from home for any extended period I turn all on to speed 3 or 4 for at least an hour before back to my default settings as to get 3-4 full room cycles per hour first.
AC is a nightmare for drying out your room AND trapping dirty air inside. In some cases indoor air is 5x worse than outside air for this reason. A humidifier will work for sure if after a week or so you still see some dry cough symptoms.
While the Paralda's are convenient enough to move from room to room, having Premium Air Purification in each bedroom is ideal and makes all the difference.
You just cant put a price on clean air in your home but ALEN definately made owning multiple Premium Air Purifiers affordable. An Energy Star Rating really helps as you then can use them all day without to much added cost.
Good Luck and trust all will work out fine!
We've had ours for about a month - 1 A375UV and 2 Paralda units. We've been running all three constantly, just varying the speeds depending on the day. I am wondering - the A375UV has been set to 'auto' mode, so I presume that it will adjust anywhere from 1 to 4 depending on the air quality? I have noticed that the speed never changes when set to 'auto', even when throughout the night, when presumably the air is not getting disturbed by us in the house, and at the time when it would be the cleanest (esp with the other 2 units running, and our place is only about 1100sqft.).
Is this a problem with the unit?
The other issue is that the difference between speed 1 and 2 is massive! Speed 1 you barely know it is on - cannot hear it at all, and only the smallest amount of air is coming out of it, yet speed 2 is too noisy to have a phone conversation in the same room.
I'm not sure what to expect, but this doesn't seem quite right. I'm posting here to see what other people have to say about it...
Thats why i use the A375UV in the living room because it cleans larger square footage which in turn makes it louder. It dont feel speed 2 is abnormally loud so I would recommend contacting Alen customer service to check out the unit just in case.
I had called about the auto function and from experience the auto function works great in the U.S but we get extreme levels of pollution in HK so its constantly running on the 4 th speed just to keep up. I decided to adjust the speeds manually instead.
I must say that it does seem from your post that your unit could be running abnormally loud. Please give us a call at 2115 8201 and we will have the unit checked out for you.
All the units are covered by a lifetime warranty so if we find there is a problem it would be our pleasure to replace it for you.
Uknowhat and Hello Kitty: If you are using the A375UV in an open space it will most likely always run on the 4th setting. When we run the units in Thailand, Canada and the U.S the speeds adjust according to the amount of particulates in the air very easily because the pollution levels are much lower.
Unfortunately the airborne particles in Hong Kong and China are much higher than W.H.O standards so the A375UV will most likely always run on the 4th speed to keep up with the workload.
Couple questions -
How large is the space you are trying to clean with the A375UV?
What is the layout of your hom and is this an open space with doors constantly being opened that attach to a hallway or kitchen?
Assuming you purchased the Whole House package, how many square feet is your home?
It's also important for people to understand how to operate air purifiers effectively to get the most out of them so I highly appreciate that you brought up this topic.
i have a question...what is a lifetime warranty mean exactly? does that mean for the lifetime of whoever purchases it? (if that's so, I should put it in the baby's name!) Or, for the lifetime of the unit before it eventually dies..I'm assuming an air filter can't possibly last for 60+ years? I just haven't really heard of electrical products having a lifetime guarantee before?
We recently purchased 5 air purifiers for our entire home consisting of 2 A375UV for the living room 1st F / 2nd F and 3 Paralda positioned in bedrooms. If you're wondering why 5 its because we are lucky enough to have a large home.
I have been holding out to post my review until I used them for a bit. After moving here from U.S with my husband and 3 kids all of them instantly reacted to the pollution with runny noses and a weird type of cough. After using the Alen air purifiers over CNY I can honestly say this is the best purchase I have made in Hong Kong because the entire family has returned back to health and breathing easier again. My husband is now considering outfitting his office with air purifiers as well but is the A375UV sold out?
By the way Hellokitty we find the noise level on the A375UV ok and it is better suited for living rooms etc.........
Sorry for the late reply! I have been off enjoying the sun in Sanya, Hainan with my wonderful wife and children.
Alen offers the industry's first Lifetime Warranty program for all of our Air Purifiers. We warrant your Alen Air Purifier to be free from defects in material or workmanship for as long as you own it.
We offer a convenient replacement filter subscription program that is administered through our online store. In this program we ship you a replacement filter(s) every six (6) months.
Alen will, at its option, either furnish a replacement part or replace your air purifier provided the product is determined to be defective as a result faulty material or workmanship while in normal use. Replacement parts or units will be either new or refurbished. Alen's sole obligation under this warranty is to replace, or at Alen's discretion, to repair, free of charge, all defective parts.
This warranty will be valid only for units in possession of the original purchaser. Proof of purchase must be presented to Alen's warranty service representative. All parts or units that are replaced become the property of Alen. To obtain warranty service, the defective product or part must be shipped or delivered to: Alen's authorized service center. All postage, insurance and shipping charges are the responsibility of the Purchaser and are not included in this warranty.
Just to make sure everyone is clear and there are no misunderstandings. The fine print does say that the filter needs to be replaced every 6 months for the warranty to remain valid which can be through a 6 month filter replacement subscription or just a replacement every 6 months. Other than that its fairly straight forward and by far the top warranty in the industry.
I hope this helps!
Alen sounds great but what really bothers me is while the prices of the units on http://www.alencorpasia.com (HK dealer) are 5-10% more than the retail prices on http://www.air-purifiers-america.com/alenreplacementfilters.asp (which is not great but OK), the replacement filters which we have to buy every 6 months are 20% more. That's quite a steep premium to pay in HK. Can you offer better prices on the replacement filters?
I assume you have taken a look around so you will easily notice that Alen is the most affordable premium air purifier on the market by far.
I feel most people that purchase our air purifiers are highly educated and can easily compare prices online which is why Alen is the smart choice and our prices are not marked up even in the least.
Considering that other brands/competitors are charging at least double the U.S retail price (100% or more) a 5 to 10% increase would be reasonable and honest. If you carefully look at the pricing on our website our packages are actually under U.S retail prices.
A lot goes into bringing an American brand to a developing market. Production runs on UK style plugs, 22OV motors, container shipping, operational costs, certifications etc.
To put things in perspective lets say you prefer to purchase from the U.S this would be the outcome if you could even get a U.S dealer to agree to ship international which is highly unlikely. High international shipping fees would also apply to replacement filters
Paralda air purifier: 500 USD (HKD3881)
International Shipping 150 USD (HKD 1164)
Plug Adapter 5 USD (HKD 39)
110V to 220V Currency Converter 30 USD (HKD 233)
No return policy
Total Price: HKD 5317
Our HK price: $3980
30 day return policy
HK plugs and voltage
U.S price: 49 USD (HKD 381)
International Shipping 50 USD (HKD 388)
No return policy
Total: HKD 769
Our HK price: HKD 480
30 day return policy
Thank you for your comment and I hope this helps you weigh your options.
Renaud, thanks for your prompt reply and explanation.
I agree that your price for the air purifier is reasonable.
Your filter price, however, I feel is quite overpriced (nearly 30% more than US retail for the "Flu & Bacteria" filter which is what most HK customers would purchase) and since the filters are an ongoing cost (every 6 months), I'm very uncomfortable being locked in to over-paying indefinitely.
Silver HEPA filter for A375UV =
your "Alen A375UV Flu & Bacteria Prevention Filter"
US price: 69 USD
Your price: 87 USD (680 HKD)
Difference: 18 USD = 29% more
HEPA with Odor Control =
your "BF25A Replacement Air Filter (A375UV)"
US price: 59 USD
Your price: 74 USD (580 HKD)
Difference: 15 USD = 26% more
You would certainly buy and ship in bulk (probably not by air) and so you're not paying anywhere near 50 USD per filter for International Shipping (no customer would). You're also not paying retail prices for the filters as well. Furthermore, for the filters there are no additional "bring to HK market" development costs as there are for the air purifier.
If your filters were less overpriced I wouldn't hesitate in purchasing.
With something like an air purifier (and color printers, electric toothbrushes, etc), the running cost of the consumables is much more important to consider than the one-off cost of the purifier itself.
Of course a primary factor in determining what air purifier to get is also the actual effectiveness of it.
Unfortunately, these days it is hard to find true, unbiased (full disclosure of affiliation/interest), honest (not made up by the marketer) opinions, testimonials and feedback to gauge effectiveness.
I guess you will have to hold back from buying a medium sized pizza once every 6 months to pay for the HKD 100 and change difference. Actually if you live in mid-levels that would be a small pepperoni & tap water.
I am honestly just kidding with you! Joking aside our current stock on the flu prevention filters was shipped by air because they were a new type of filter developed to combat the flu that hotels required immediately so they needed to be rushed in during the pandemic.
Have a closer look at the sites you gave me....unless your looking to wait 7 days for ground shipping to receive your order only within the continental U.S shipping fees for one filter is between 14 USD and 69 USD. We offer FREE SHIPPING within 1-2 on business days across Hong Kong, Macau & Mainland China on available stock this again brings us under the U.S price.
Once stock is low we will purchase another order in bulk that would arrive by sea and we will strive to continue offering the best prices in Asia.
This is just my personal opinion and I am sure other members on this board would agree the same that we are still the best value premium air purifier in town by miles!
I presume from your above post that you didn't check out our flu prevention package. You will notice that our prices are again under the U.S retail price + you save close to HKD 500.
On further thought I am thoroughly enjoying my conversation with you so you have just negotiated a deal for all AX members!
We are currently sold out of the A375UV air purifier because they moved unexpectedly fast due to higher than expected demand.
For a limited time we will offer a 15% discount on all pre-orders of the A375UV to all AX members. Do note that A375UV air purifier orders will be delivered free of charge to your home at the end of March.
Everyone can simply go to our website add the A375UV to the cart and enter coupon code GARMINGIFF click recalculate and you will receive HKD 765 off your A375UV purchase!
Nice work GarminGiff!
HA!! OK, I'm flattered... Thank you! As I share your new promo with friends you just may have a few more customers. You've also piqued my wife's interest which is a good thing (many spouses aren't keen on dropping $5K+ on the next new household appliance)!
Nice move! :)
BTW, when were the A375UV and Paralda models launched? Are any new models coming soon?
Also, can you offer the 15% off on your "A375UV with Flu Prevention Package" as well? How about a special deal with one A375UV and one Paralda? Probably asking for too much, huh?!
You do have my respect and admiration. Thanks again!
Well, it is sometime difficult to explain a very real invisible threat to our significant other. Its actually the only home appliance that can save lives, reduce hospital visits, reduce school sick days and the list goes on.
The Paralda is the newer model launched in 2009 and the A375UV has been around for a few years with small design changes on a yearly basis.
No plans to launch any new air purifiers right now but different types of filters are being developed which you will be able to simply insert into your existing unit.
As you know the flu prevention package is already discounted so that great deal on the site stands. Do note that it is for a limited time until current stock is depleted.
Feel free to give our office a call this week and we can discuss your needs.
A lot of people might not know this but we also offer a C.O.D service if you prefer not using a credit card. Simply add your products to the cart and when you are prompted for a payment method choose C.O.D (which means cash or cheque) and our driver will drop it off at a convenient time for you.
I have a small flat - 500 sq ft. It has an open kitchen and glass doors that open up to a small terrace and garden. The living room/kitchen is not more than 240 sq ft and the bedroom 100sq ft. I suppose a paralda is sufficient? Can I leave that on the whole day in the living area and nove it to the room at night?
A friend has a 2 room flat 669 sq ft flat - I am assuming that one paralda will work for her too on the same basis as what I had in mind for my flat? Please advice.
While A375UV is larger and I am asuuming more efficient - would it be too big and therefore unnecessary for the above flats? Is bigger better?
For yourself the Paralda would be sufficient and I would probably place it in your bedroom and bring it out to the living room if you have guests over for targeted protection. If your bedroom door is closed you would not be able to efficiently clean the living room and vice versa.
As for your friend.
Option 1 for optimal performance/efficiency: Purchase 1 Paralda or A375UV for the living room and 1 for the bedroom.
Option 2 quite efficient: 1 A375UV for the living room and keep her bedroom door open at night so the particles in her bedroom can be efficiently cleaned. She may even want to carry the air purifier into her bedroom at night and drop it down to the first speed so the noise level is non-existent.
Option 3 save $$$ Depending on where you spend your time carry 1 Paralda from room to room and go to sleep with it in the bedroom.
Its always important to have targeted protection in the bedroom because this is when our body is rejuvenating itself and where we spend most of our time.
Bigger is not better in terms of efficiency because in my opinion both units are equal. Efficiency is based on the amount of particles removed within that allotted space. You would achieve approximately a 95- 99% change in air quality one hour after running the unit.
I simply always recommend the Paralda to my friends for bedrooms and the A375UV for living rooms.
I've ordered the A375UV with the discount code (nice one GarminGiff!). Wish I didn't have to wait until the end of the month though with days like today! Just a touch of pollution in the air:
It's nasty... as I pointed out on a post on THINK... there was an article about the Shanghai > Hong Kong rivalry... as the thread indicates there really is no rivalry as HK will remain the financial centre for China for years to come...
However... HK could get a step on not only Shanghai but Singapore by cleaning up its air...
Look at this mess: http://www.businessweek.com/news/2010-03-21/hong-kong-wins-no-weekend-respite-as-air-worsens-for-fourth-day.html
Government API at 498 in Tai Po ... the scale only goes up to 500.
almost 12 times over the WHO limits.
I'm so glad I have the house kitted out with Filtration Systems....
I have been considering an air purifier for some time and with the recent API I am about ready to spend the $$. However, it is still tough to make a choice on the best one for me.
One concern I have on UV lamp type units is whether it is ozone safe. The IQ people told me it is not . Here is an interesting write up on UV type air purifiers: http://www.air-zone.com/uv.html
Another concern for me is buying one that I can bring back to the US, so it needs to support 120V.
Can the Renaudlifestyle please answer this.
I am also considering the Giabo from Wing On as it is very similar to yours and much less expensive.
Firstly, do NOT get an ozone generator. Not good.
UV bulbs are most effective when used alongside a titanium dioxide (TiO2) screen.
For any air purifier models you are looking at, I would recommend choosing one that has a washable pre-filter (takes a lot of the bigger stuff out of the air, and greatly extends the service life of your expensive HEPA filter) + HEPA + Carbon Filter (for odour removal) + UV/TiO2 + negative ionizer (Sharp Plasmaclusters have a negative AND positive ion feature... I would recommend using that only when you're not in the room).
Thanks for the note Telemundo - This Giabo has what you suggested. The price at Wing On is $1800 HKD for 300 sq ft units. I like the pre-filter idea too.
Thoughts on the IQ brand - They seem to be the best and cover a lot of area, but $10K plus takes some selling.
the IQAir are the very best. And that comes with a premium price tag.
Next one down would be Alen and BlueAir from Sweden.
Then a wide gap .... and then the rest.
Flyboyhk hit it right on the button and this is the exact reason why Alen is the number one selling air purifier in the U.S and why we are completely sold out in Hong Kong and can hardly keep up with demand.
Very simply IQ is retailed at $10,00 - 15,000 and Alen $3980 to $5000. When most people need more than one unit to clean an entire home the numbers don't lie.
Only a few brands in the world are worth looking at with the top 3 having comparable performance.
G.O.D. have quite a high-capacity one with pre+HEPA+carbon+UV+TiO2+neg ion, for under $2K if I recall correctly.
I have only tested the top 5 brands in the world for our own internal research and others really cant compare. I certainly dont want to waste time talking about the others because they simply dont spend enough time on R n D.
Put it this way premium air purifiers like Alen and our competitor will filter 99% percent of the particles and the rest will test between the 30% and 70% range so I prefer not discuss an array of air purifiers that can't substantiate claims through independent testing.
We cant compromise on quality or our families health but luckily we all have an affordable high performance alternative to paying top $$$$ on the market now.
You can save yourself a couple bucks with the lower end brands but in the long run you certainly aren't doing yourself an favors.
I don't buy the marketing and if these guys say the HKUST helped, I would believe they are tying to truely combat the issue. The Giabo units claims this:
Removal of bacteria and VOC
800 cfu/m3 after 1 hour
Reduce 99% Fungi
Destroy 90% of VOC (a room of 150ft2)
So, my question is do you have a unit that also supports 120V for sale here?
Okay, what do you have and recommend to combat suspended airborne particulates?
Is it even possible to eliminate that stuff?
I'm not concerned with bacteria and fungi and whatnot-- just the hardcore pollution from traffic and such.
Say for a 650 sq ft flat?
look up some of the previous posts on this thread ... I know there are very many and it's a lot to read but one of particular interest to you might be my laser counter test result ... 124 days ago. that should answer your question.
It would be my pleasure to answer you questions by finding the post flyboyhk made approximately 4 months ago. (just scroll up the page and you will find an unbiased test of Alen vs Competitor)
Yes, we are a paid advertiser on this site but at the same time from a concerned father I am not trying to confuse your mind with a bunch of hoopla to make a buck or am i trying to pass on my goodie two shoes corporate ideology like so many do!!
I have already explained that all others don't compare including the link you just posted which is absolutely meaningless against the pollution we are experiencing right now but you know what?
The same filtration called PCO is included in our A375UV Multi-Gas Air Purifier. In reality this is a a good addition to have on any air purifier but true protection comes from true Hepa filtration which is not included in the link you posted but is in Alen.
If we were to take a laser particle counter and test the unit they mention they would most likely achieve a 2% filtration rate which is a far cry from the 99% the premium brands are doing right now. (not to bash your research but this is like comparing a `1950 rusty tricycle to a Lexus)
I do understand that it is important for people to do their own research but the information you are posting is not beneficial to AX members right now and only confuses fact and fiction.
If you or any AX members have any detailed question feel free to call 2115 8201 and it will be my pleasure to answer them. I do understand that you are trying to find the best solution for you or your family but look no further than the top 5 brands in the world because there is a reason why they are ranked so.
OK... I have to put my 0.02 in here...
I have a laser particle counter. The air coming out of the back of my "cheapo" China units is frankly cleaner than that coming out of our Sharp Plasmaclusters. Tested it also on an IQ Air... same.
Yesterday and today I went around our home and personally inspected and cleaned our air purifiers (we have 5). Pre-filters not quite clogged, but not far off. Nasty. HEPA filters grey on on one side, white on the other. This is after 3 months since the last cleaning.
1st point: Make sure your air purifier has washable pre-filters
2nd point: My China unit HEPAs are dirty on the incoming side and clean on the outgoing. They seem to work very well.
3rd point: Get SOMETHING. You really do need it in HK. Make sure you sleep with it on, in your bedroom.
I'd be surprised if any floor standing air purifier sold in HK didn't massively help. If Alen removes an extra 2%, then great.
I've used IQ air, and they are very good too. The additional cost of Alen and IQ air is up to the individual.
@Telemundo, good points and thanks for sharing.
Please share with us what "cheapo China" units you have. What's the brand/name and where did you get them from?
When you said "IQ Air... same" did you mean particle measurement for IQAir was same as your Sharp Plasmaclusters or same as your China units? And what were the particle readings (roughly)? Thanks.
On a side note... is it just me or does everyone who subscribes to alerts for this thread receive THREE emails for each new post? Quite annoying!
Although Sharp probably has the largest market share. You're absolutely right about the Sharp testing very low because they use another type off propriety technology that doesn't even come close to true Hepa Filtration.
But where you are wrong is that there is a massive difference in performance between a premium brand and el cheapo brand. Don't expect me to go out there and buy the 10 cheapest units I can find to prove my point though because it is just a waist time.
This will be my last post concerning el cheapo brands because they simply aren't in the same league.

By the way your discount has saved people a few bucks. Nice one! It will be ending soon once the new shipment arrives though.
Warning: Smog lowers kids' IQs, even before they're born.
The five-year-old children of city mothers who regularly breathed in car- and truck-polluted air when they were pregnant scored significantly lower on IQ tests than kids with less exposure, a study released Monday found.
The 249 moms tested -- all from the South Bronx and upper Manhattan -- wore backpack air monitors for 48 hours during the last few months of pregnancy.
Their pre-schoolers scored four or five points lower on IQ tests than kids who were not exposed to pollution.
That's a big difference that could affect school performance, said Frederica Perera, director of the Columbia Center for Children's Environmental Health, who led the study.
Here is the full article
Besides an air purifier there are certain steps we can take to protect ourselves during pregnancy.
It would be interesting to start building a list of positive things to do to better protect ourselves.
Can you please explain the differences between your 2 air filters? I have 2 Paraldas but need one for my lounge area. Also, we have had ours for a year now and have not yet changed the filters. We only run at night in the childrens rooms and do spend about 4 months a year out of HK but I would have thought the inidicator light would have come on by now.
The main difference is that the A375UV cleans up to 800 sqf. All brands put high square footage on this coverage but the reality its only when people run their air purifier on the highest speed that you achieve this coverage so for the average user best performance would be at approximately 600 sqf running it on mid speed.
I find the Paralda is quieter than the A375UV so the A375UV is better suited for living rooms / lounge areas which can cover the open space into the kitchen etc...
The A375UV also has an additional feature called PCO (photo catalytic oxidation) that permanently removes a wide range of gases, volatile organic compounds, smoke, and ammonia. Other gas air purifiers typically use carbon, which can be a problem because carbon stores gases which can be released at a later whereas our solution permanently eliminates the gas/odor on contact.
The filters typically last approximately 6 months of continuous use and sometimes less depending on the area you live in. It is highly likely that you could get 1 year of use out of the filter with occasional evening use.
I would also recommend to run them more often even at a lower speed in your children's room. I don't know how old your children are but their lungs are usually still developing unit age 7,
Thanks for your reply. I actually checked the filters and they are filthy on both sides so will order some more right away. I will also get the A375UV for the lounge and another Paralda for our bedroom. The kids are 2 and 5 so still little. Can you please tell me how to best run all of these? Obvioulsy even in HK we need to open the windows for some time and can't keep them always closed. Is it best to air out the apartment in the morning and then run filters on high after closing adn move to low for the rest of the day? We usually just run them inthe kids rooms at night on the second setting. I am assuming from your response above we should run them all day instead?
Well, in Hong Kong its best to have these running most of the time even if it's only on a lower speed. Since I dont have allergies I turn on the air purifier in our bedroom when I come home but since my 2 year old is heavily affected by the pollution I make sure to have my A375UV for the living room and his bedroom Paralda running most of the time. I do turn them down to a lower setting when we are not home though and off during holidays.
Adjusting the speed of an air purifier is sometimes not at the top of the list so you can actually program both units to automatically adjust to different speeds during the day but I simply prefer to switch speeds manually. A couple hours before your kids go to bed turn the air purifier up to the 4th speed to give the room a good clean then drop it down to the second at night and down to the first when you go out for the day.
Opening your windows in HK is just like inviting outdoor pollution to be part of the family. That being said we are all human and this is more about prevention then trying to make our home a hospital room either. My wife does open the windows on a fairly good day but we make sure to turn the air purifiers off so they are not working overtime and crank them up after shutting the windows.
there is more to indoor pollution than RSP ... you still need to air out your room frequently.
A lot of furniture and paint will leech Volatile Organic Compounds, and the best way of getting rid of them is airing the room out. (Yes yes, I hear you say, the A375 can handle them, but it takes so much longer to break them down than to simply flush them out)
High levels of CO2 will make you tired - again - air the room out.
Then shut the windows and run the air filter on a high setting for an hour and you'll have clear air with enough oxygen :)
Thanks for the clarification flybohK...I second the above post.
Placed an order for a couple more Paralda's a few days ago. I know your site mentions you sold out......any idea when we can expect delivery?
We are expecting the shipment during the 3rd week of April and will start deliveries shortly after. (1-4 business days).
Extremely high demand has also started a lengthy waiting list but anyone on the list and future orders will receive an air purifier this shipment. :)
What is the power cord like on these units, i.e. is a 110-220 laptop-like brick, or are they plugged directly into the wall and 220 only. I'm moving to Hong Kong, but if it were possible to bring these units back to the US and have them work with just a simple cord (and not a power step down transformer) that would be nice.
Second, I arrive the last week of April (two weeks from today actually). When should I put in my order to get delivery timed just right to match my arrival? Or should I send them to a third party that is currently in HK just to be sure they arrive?
The power is 220V with HK style plugs that are inserted directly into the wall. If you wanted to use them in the U.S you would need a voltage converter.
We have enough air purifiers coming in for everyone but if you wanted to get higher on the waiting list I would suggest placing the order sooner than later. We would of course hold the units at our warehouse until you were personally ready to take delivery.
If anyone has a smoking problem at home Alen will be launching a new type of filter within a couple months that can be placed in your existing units. The filters changes the molecular structure of the smoke and completely eliminates odors.
I ordered a whole house package today April 26. What's the current waitlist / delivery time looking like?
The wait is almost over. Our shipment of Paralda air purifiers arrived today and the A375UV Multi-Gas air purifiers arrive next week from the U.S.
Of course its our obligation to process the orders at the beginning of the waiting list but it shouldn't take us long to work through it. I estimate that you would receive your order next week.
For people reading this thread - once we are completely restocked delivery is 2-3 day under normal conditions.
Thank you for your patience!
Thanks. The Paraldas arrived last night. I guess the other unit will come next week. Just in time too as Greenpeace site is showing pretty yucky air despite the rain.
On a slightly related matter, i've heard people state "air in the midlevels/south side/cyberport etc is better worse than air in X". Are there really that many geographic differences on HK island? It seems so small in comparison to large masses of air pollution such that slight variations are basically irrelevant.
You can get away from the roadside emissions - which are however quite significant - by moving to greener, low density living areas like Tai Tam, Stanley etc.. And if you stay away from Pok Fu Lam/ Cyberport / Ap Lei Chau the effect of the Lamma Power Station gets less pronounced.
But that's all. Any other claims are wishful thinking.
This is shameful... air purifiers offer protection indoors but we can't lock ourselves indoors... how bad does this have to get before something gets done? Because apparently the smog gets worse year after year after year...
Hong Kong Air Pollution Has Two Worst Quarters Ever
Hong Kong’s air pollution was the worst on record during the past two quarters, sparking regular government health warnings and growing discontent among the city’s 7 million people http://www.businessweek.com/news/2010-05-03/hong-kong-air-pollution-has-two-worst-quarters-ever-update1-.html
Hong Kong pollution expert leaves to seek clean air
Hong Kong's leading authority on air quality said Thursday he is leaving the city to avoid its polluted air and keep his respiratory problems under control.
Anthony Hedley, who created the Hedley Environmental Index, which tracks the public health and economic costs of Hong Kong air pollution in real time, is relocating to the Isle of Man off the west coast of Britain.
"I need to reduce my exposure to polluted air because I know from experience that my respiratory symptoms subside quickly when I am in cleaner air," the 69-year-old Briton told AFP. "Because of my medical history I now want to avoid the biological stress which comes directly from breathing the polluted air in Hong Kong."
Renaudlifestyle - Have the A375UV Multi-Gas air purifiers arrived? I put in an order in March and am still waiting despite being told at the time of purchase that they will be delivered end March / beginning of April.
how does the Paralda as well as the A375 determine the filter condition? is it based on time since last reset or actual pressure drop across the filter?
No reply from renaudlifestyle. Is there anyone out there still waiting for their air purifiers?
Sorry for the late reply as I have been out of the country. We did receive our shipment of Paralda air purifiers last week and all have been delivered.
After speaking with the C.E.O of Alen Corp USA this morning he mentioned that we all need to wait another 10 days until the A375UV's arrive.
I just think that headquarters didn't realize how large of demand there was for air purifiers in Hong Kong hence not acting quick enough to replenish our inventory. Well now they know and have guaranteed us that there will be no more delays moving forward.
It is based on a combination of running time and fan speed to estimate the
amount of air that has flowed through the unit.
I understand the purifiers are life time guaranteed but does this guarantee extend to second hand purchasers? A friend is migrating and has 3 paraldas for sale. He says they are 2 years old. I am keen on buying them from him but am wondering if the lifetime guarantee would be extended to me?
Here is a link where you can review the lifetime warranty terms and to answer you question directly it does only apply to the original owner.
I am moving to Beijing and am interested to purchase alen air purifier. But how can i change the filter in future, i rem u mentioned earlier that the filter need to be changed monthly (if the air pollution is bad).
Actually the filter only needs to be changed approximately every 6 months. We recently opened a mainland office in Shanghai so all future filter replacements can be purchased directly through them.
Free home delivery also applies across China so filter replacement wouldn't be a problem.

does the warranty also cover in China if i purchase the unit in Hong Kong? thanks
Yes, the warranty does apply in China and future servicing can be done directly through either office.
I do suggest purchasing in Hong Kong because our China price is slightly higher due to a 15% import fee & 17 VAT tax.
Guess this is the reason why HK is the mecca for electronics.
Hi, am interested in the purifiers but would like to understand which parts and proportions of HK smog is filtered out by these filters, and also which parts and proportions are not? Also does this differ per product?
To split up the smog into portions would take an entire research team a year to research. There are literally 1000's if not 100'000' different type of pollutants floating around.
I will try to break it down for you a little later on but you can find a wealth of info on the matter scrolling up the thread.
I know its terribly long :)
Here is a quick overview of the type of particulates that can be found in the smog.
A quick thank you to everyone for your patience that had to wait for the A375UV Multi-Gas air purifier.
I am now confirming that all Alen air purifiers are back in stock!!
Can u describe the difference btn the two. are they functionally the same...is it just size and therefore the time it takes to clean up the room?
Paralda HEPA Air Purifier
A375UV Multi-Gas HEPA Air Purifier
trying to decide if i want a whole house pack or individual ones. Thanks!
when will you start delivering the units? I placed my order a week ago and I haven't been contacted by anyone.
Deliveries started Friday. Since there was a lengthy waiting list we have the obligation to process all the orders placed before last week. As for a time line I think you should receive your order by Tuesday or Wednesday at the latest.
Feel free to email us your order number and I can check on the status.
Received my Alen air purifiers today. The plug doesn't quite fit into the HK standard sockets. I presume they need changing? Is there anything to look out for e.g. transformers?
Sorry, my bad. They are HK plugs. One of the legs of the plugs is wonky that's why I thought they don't fit. I guess we'll be in touch to have them replaced. Cheers.
All the air purifier are 220V with HK style plugs so I can only assume it was banged up during transportation. Please call us at 2115 8201 with your order # and it would be my pleasure to offer you a new replacement.
I live in singapore currently. what is the shipping charges?
I presume that a transformer is not needed but what about the adaptor?
does alen test their pdts like leak test b4 selling to the customers? i think only iqair does that. i m not sure.
Send us an email with your shipping address in Singapore and we can get a shipping quote for you.
Singapore runs on the same voltage as HK so our models would work for you.
The reason why Alen and it's main competitor perform so well is because of the leak test. Both air purifiers are properly sealed which allows them to consistently be ranked at the top of the industry.
Still loving these air purifiers. Although I just changed the filter on the A375UV and the filter light is still indicating that it needs to be changed.
Is there something we are not doing properly during the switch?
Resetting the sensor is covered in page 5 of the instruction manual.
Simply hold the timer button for 5 seconds and this will reset the sensor and let the air purifier know that you have installed a fresh filter.
This will definitely do the trick!
Hey Renaudlifestlye, I'm soon moving to Shanghai with my company. Do you sell your units locally there? I recently visited Shanghai I was coughing everyday.
Can someone tell me how to use these machines? Specifically, do you turn them on the whole day and forget about it? Or do you turn them on for an hour everyday and then leave it off? Are they quiet enough to sleep in the same room with the machine on?
Sorry for the late reply. Even though we sell air purifiers I still had the need to get my fix of good ole outdoor Canadian clean air.
According to the pollution levels we have in HK I recommend running the Alen air purifiers 24 hours a day.
When we're not home I personally keep the air purifiers on the 1st speed (4 total) during the day to control the indoor environment. When we arrive home at 6 o'clock we crank all the air purifiers up to the 4th speed for 1 hour to give the home a good clean then we drop them down to the 2nd to control the environment again.
Alen air purifiers can do about 4 air changes per hour so you can efficiently clean a room in relatively short period of time and the rest of the time you are controlling the environment.
The Paralda air purifier is one of the quietest Hepa air purifiers in its class and can comfortably be used in the bedroom on speed 1 or 2 without the noise disturbing you.
The A375UV is extremely efficient in cleaning larger areas (800 sqf) which means it is a little louder so its better suited for open spaces like the living rooms, or open office space.
Our recommendation for the home is the whole house package which gives you a substantial discount by purchasing an A375UV for the living room and Paralda's for bedrooms.
Thanks. Will probably get a couple of the Peraldas to try out.
Glad to hear you moved forward and will enjoy a little clean air.
Air Pollution Sparks Protests
I have purchased a Peralda. Can anyone advise on locating the unit, ie. Can it sit behind a chair or a sofa and still be effective or does it need to be out in the room.....thnks
I have purchased a Peralda. Can anyone advise on locating the unit, ie. Can it sit behind a chair or a sofa and still be effective or does it need to be out in the room.....thnks
It can definitely be in the corner of the room next to a sofa or a chair. I don't recommend having it directly behind the sofa.
Optimal performance would be having the clean air vents blowing towards the area you spend the most time.
Overall just make sure there is enough room about 20 cm on each side so the unit has room to efficiently pull in and blow out air. The Paralda does 4 air changes per hour.
Year after year after year after year... story after story after story complaining about it... petition after petition after pertition... and yet the air gets worse rather than better...
Hong Kong Pollution Climbs to Third-Quarter Record
Hong Kong’s roadside air pollution reached record levels for the third quarter, according to Bloomberg calculations, putting the city’s government under more pressure to clean up the environment.
when should i change the filter? wait til the red light is on? Can't remember when did i buy it.
You would usually change the filter once the red light comes on. I do suggest changing the filter at the 6 month mark so you can take advantage of the Alen Lifetime warranty.
If you can't remember when you purchased the air purifier feel free to email us at firstname.lastname@example.org and we can check our records for you.
Here is the lifetime warranty link. http://www.alencorpasia.com/Articles.asp?ID=141
Just moved to Hong Kong and came across this thread. Was about to purchase the Phillips air purifier (http://www.philips.com.sg/c/water-air-purifiers/4-step-filtration-smart-sensor-30-m2-ac4004_00/prd/) at Fortress but decided to do some research. Have never heard of Alen in the US, so this is all new to me. I have heard of IQ, so I was leaning there.
I do have some questions:
1. Do the Alen air purifiers filter out particles less than 0.3 microns? The Phillips filters out anything larger than 0.02 microns (20nm). The IQ ones supposedly filters down to 0.01. I wasn't sure where to find this information for Alen, I looked on the website but could not find it.
2. Does anyone own both the Alen and the IQ? Is there a noticeable difference in noise level?
I'm still on the fence between Alen and IQAir. What I like about the IQAir is they will come and do a free asseessment of your premises. I had them come and test my office and it tested quite well - zero formaldyhide, under 230 for VOC and around 4500-6000 particles/litre of air (>0.3microns). IQ Air claims to get rid of >99% of particles down to 0.01microns (ie virus size) and was used in HK Hospitals during the SARS outbreak. I know this was started as a Renaud thread but in the interest of fair disclosure I mention the IQAir experience that I have had.
Hey all, I had the same challenge after using the Japanese made AP's that didnt solve our quest for clean air. After spending $3K here and there, finally got down to business of serious research and found the PREMIUM Air Purifier Segment in which IQ and ALEN were both highly regarded.
What honestly did it for me was ALEN simply got the job done from every review I read and did it affordably. I purchased one as it was half the price of IQ and it worked fantastically. Everyone I know in HK who has one says the same.
Now I have Paralda's (4) in all my bedrooms, and A375UV's in my larger living spaces and even one in my office at work.
Once you get to only considering the PREMIUM or TRUE HEPA Air Purifiers the list gets very small, and you are at this point "splitting microns" on performance.
The key thing is when buying AP's for your whole home like I did, if ALEN is 50% less expensive on the initial event it makes a huge deal. Further, the units I find are 70% less expensive to maintain on an annual basis which is something we forget to consider.
Lastly, the units are much smaller than IQ, very quiet and look great in the house. IQ was big and bulky looked like a hospital appliance.
If you have unlimited budget, want the absolute best (by a micron margin) and dont care what it looks like or how much space it takes up go IQ but honestly why would you.
I've been using ALEN AP's for almost 2.5 years now...they just plain work at a price I can justify!
Keeping with our belief of premium performance and affordability we are now launching a special promotion on group orders.
Groups that can put together 10 air purifiers or more will receive a 10% discount on any air purifier or package on our website.
I bought one the other day and found that the instructions are not clear. I am afraid i dont use it and wished i hadn't bought it. I believe this product thrives of people's paranoia about invisible germs. My opinion is to save your HK$3700.
im also a little cynical of all these poeple above who rave about the product. How objective are they really?
Good luck to renaud lifestyle - although i think they're raking it in . . . Tanks Ed for posting.
Aw, c'mon, it's not rocket science.
Just plug it in and switch it on.
I suggest you do. You should see the state of our pre-filters every two weeks (I recommend getting units that have a washable pre-filter before the HEPA filter, as they extend the life AND efficiency of the HEPA by removing all the bigger crap out of the air.
Please allow me to assist with your research on people having "paranoia about invisible germs." I am quite sure the World Health Organization is not an imaginary organization with 1000's of doctors who spent their entire life studying to dream up these statistics.
The operation of the air purifier is very simply but should you need assistance feel free to call our office and it would be my pleasure to personally walk you through it. Alternatively simply scroll up the thread because it has been talked about in the past.
Here are a few reports that have come out recently about the adverse effects of air pollution which will make you sit up and sniff the air around you apprehensively:
* According to a study, living in a major city places people at a higher risk than living in the radioactive zone in Chernobyl.
* According to the World Health Organization (WHO), about 2 million premature deaths are caused each year due to air pollution in cities across the world.
* A recent study has revealed that exposure to fine particle matter in polluted air increases the risk of hospitalization due to respiratory and cardiovascular diseases.
* According to a German study, people who breathe in the fumes of heavy traffic regularly have higher chances of getting hardening of the arteries, which is associated with the risk of heart attack.
* A Scottish study has shown that jogging with traffic around results in reduced blood flow to the heart. This is particularly dangerous for people with stable heart disease, because it can trigger off cardiac arrhythmia or even a heart attack.
* According to a study conducted on eight-year-olds in Mexico City, being exposed for a long time to high levels of polluted air reduces lung function and growth in children.
* According to a 20-year study conducted on the residents of Los Angeles, it has been shown that the adverse effects of air pollution have been grossly underestimated. The researchers opine that chronic health problems due to particulate matter in the air may be double or even triple times greater than the estimates available currently.
As a new parent this is a major concern.

Hey Renaud, air purifiers working great. Im living in Shanghai and need the filters changed. Where can i buy them?
You can visit our office in Shanghai or just place an order from our mainland website.

PM me if you need assistance and I will put you in touch with someone
This note just arrived in my email... brutal...
1 in 4 people (reported yesterday on RTHK) now ready to leave HK (up from 1 in 5, last year), because of the air
I like the unit, my only complain is it's "bright" in the room of my kids at night, i have covered some portion with black out curtain but still bright. any suggestions? can i cover the sides as well where the air comes out?
Is it bright because of the UV lamp inside the unit??
That would Not Be A Good Thing.
it's only for my kids room as i prefer them to sleep in complete darkness, their room is small so a single light from this air purifier makes their room "bright", but if it's in our room, no issues at all.
Hi Honey Pie,
I assume the light your talking about is from the logo on the Paralda. Simply stick a black piece of tape over the Logo and it will be fine. UV is used inside the machine to eliminate bacteria and viruses so it's not the UV causing the glow Alen put a small light to make the logo light up last year but this will be turned off on all 2011 models.
Glad to hear you like the performance of the air purifiers :)
Excellent Xmas Discounts on our Whole House Packages until December 22nd, 2010
Can you help me understand the difference between Alen "true" HEPA filters and the sharp "true" HEPA filters. Living in HK I'm mainly worried about the respirable particles and it seems the HEPA filter is the core of the filtration.
The other recommendation after reading other reviews is the importance of having a 2 stage filter. 1st stage just to pick up the large dust particles and washable (like aircon filters) to avoid the larger dust clogging the HEPA filter and reducing the efficiency. It's amazing the amount of dust picked up in my aircons and we clean them weekly. Does the Alen need cleaning at all ?
Not knowing the Alen units, all I can say is that having a washable pre-filter is important.
My pre-filters are constantly clogged. A quick turn under the shower followed by a hang dry and good to go. HEPA lives to breathe another day.
Some of the lower end models claim to have Hepa but in actuality it is a lower quality material which doesn't capture particles efficiently. This has forced brands to call their own filters True Hepa to differentiate themselves from fakes but in an honest world Hepa is Hepa across the board.
Telemundo does have a valid point that a pre filter can extend the life of a Hepa filter and even though the Alen A375UV does have a pre-filter it doesn't necessarily affect the performance of a good air purifier.
Having a properly sealed filter and multiple filtration technologies is what differentiates the top brands from the others. Almost all brands use the same type of Hepa material in the filter but only a small number of brands have the filters properly sealed in the unit which drastically enhances overall performance. This means as air is sucked into the unit 99% of the air passes directly through the filter capturing all the particles with it. (this is great for you) Only a few brands in the world can achieve 99% efficiency out of the air purifier and Alen is one of them.
The reason is very simply to why some air purifies don’t rate as high but still have hepa filters. These air purifiers are simply not sealed very well. 60% of the air is sucked directly through the filter and the other 40% by passes the Hepa filter material all together and gets blown back into the air.
Another claim/marketing tactic that many air purification companies use is that their filter is 99.97% efficient. You would see this advertised on all brands because it seems like an impressive number. This is misleading but not a lie because Hepa material is 99.97% efficient but it doesn’ t mean the air purifier as a whole is 99.97% efficient. Many brands fall between the 50% and 80% efficiency range and the top brands like Alen are in the high 90 percentile.
Hong Kong's 2010 Pollution Level Is Worst on Record, Hurting City's Image
Sadly... we are impotent to fight this... other than trying to clean our home air...
I would add, home AND office.
Responsible and caring companies would provide air filtration. Failing that, get your own air purifier and put it in your office / cubicle.
With home and office, you have the majority of your day covered.
Not sure if an air purifier would do in the cubicle if you have an open office space.
Private offices can be cleaned with one unit but for large open spaces you would need a few strategically located to purify that much air.

Alen - Should the UV light be on for and chemical removal? I thought it was just for bacteria and viruses.
Yes, if your using the A375UV you should turn on the UV light for gas and chemical removal.
What model would you recommend for abed room about 5 meters by 4. How much will it cost me and is there any sort or try before you buy opportunity ?
I personally use the Paralda in our room and the baby's room. The cost of the Paralda is 4980 and discounts are availabe for multi-unit packages.
We don't offer free trials but are more than confident about the efficiency of the product so we do have a 30 day return policy which is virtually the same.
Hi, I am keen to get a A375Uv and am wondering if there are any ongoing promotions? Cheers...
All of our promotions are currently displayed on the website.
We can customize a package for you if you don't see the combination suitable for your home.
Air pollution may hurt kids' lungs
I've read with interest these posts regarding the purifiers.
So say I do not purchase the filters every 6months via your website or via you. Does this mean I'm not covered by the lifetime warranty? Pls can you confirm.
Do u have the flu type filter? I could use this then and the use the normal hepa which came with the machine for after 6months?
Also which model is best for a 200+ sq ft bedrm.
Does the 2011 parald version remove the glowing light logo?
Lastly where are these made, china?
Im reading that its best to have the uv light on, ion on etc.. so what's the point having on n off then.
Thx, really need reply before I spend. Cheers
hope to get a reply soon on this.
i don't get it when you have to keep buying filters to keep the warranty.... am i mistaken or?
Our lifetime warranty is one of our biggest advantages over the competition because it says a lot about how much we trust our quality. All the warranty information is clearly posted right here. Yes, our U.S office requires that you change the filter every 6 months to maintain the warranty. You can rest assured that with Hk pollution you will need to.
The few top air purifiers need filter changes approximately every 5000 hours / 6 months except some of the lower end brands have washable filters which aren't very efficient. We are the master reseller so I dont have all manufacturing details for you but i believe 17% of the Paralda is made in China with 83% rest abroad...just like the ipad :)
The bottom line is that Alen remains the top affordable premium performance brand on the market and has helped 1000"s of families breathe significantly better in hk.
You really cant go wrong with Alen....if you have further questions feel free to call one of our specialists for more info.
Thanks for the question and hope this helps with your decision making process.
guyinhk - i haven't decided but would be interested in hearing your thoughts on iqair (eg quality of the product, which model you purchased, price). would you mind sending me a PM on this? much appreciated.
I forgot to mention the reason the UV light can be turned on or off.
1. When the UV light is on it kills bacteria and viruses trapped in the filter.
2. Some people don't turn it on because they believe their body just adjust to bacteria and viruses naturally. Alen needed to adjust the function for this side of the market.
3. The truth is you should ABSOLUTELY always have it on. Any air purifier on the market that doesnt have this function could possibly be heavily contaminated after a period of time. Imagine an air purifier capturing thousands of viruses, bacteria, mold etc.... You go to change the filter and these a re-released in your home.
Air purifiers that dont have this function have a dirty little secret....Mold can actually grow inside of the machine after a period of time. You can imagine with HK humidity how this could easily occur. If you purchase Alen turn it on or purchase an air purifier that has this function to prevent this from happening.
When UV comes into contact with a virus within 1- 12 cm it kills it, and withing 24 cm it changes its DNA rendering it harmless. Purely capturing it is only half the battle.
Are there still discounts being offered for bulk orders better than the website offer? If so I am looking at the A375 and Paralda pair, please MSG me if anyone else is interested.
Larger corporate bulk orders between 12-30 air purifiers are available. If you get a group of people together email us at email@example.com and we can customize something for you.
All, havent been here for a while as not needed, my whole house if protected by ALEN AP's. Paralda's in each bedroom, A375UV's in the larger living spaces and even have a Paralda in my office!
I have owned these for three years now and even found that they are protecting us from Allergetic Rhinitis which is common in Asia. This is that allergic inflammation of your nasal airways which is ofter triggered by house dust mites and cockroaches.
You all know people with symptoms of sneezing, itchiness, blocked and/or runny nose which occur daily! I have done some research on this and it basically occurs when your immune system misinterprets harmless dust mites and the antibodies kick in!
I believe the future of Air Purification will rely solely on dealing with Ultra-Fine Particle Filtration which are the most harmful and only PREMIUM True Hepa AP's can operate at the efficiencies needed to do this. Particles less than 0.003 are the key and Ozonators have 0% efficiencies, Ionizers 2% and even Ordinary HEPA avg. 37%, while if you look at PREMIUM AP's they offer 95% and above.
We went through 3 different types of so called "Top Brands" and found none could make a change in our air quality and solve our breathing problems. We over rotated to high level commercial grade but impossible to justify.
We looked at PREMIUM reports up and down, every bloody website, white paper and research paper and came up with two recommendations. ALEN & IQAIR!
Further examination found ALEN to be as efficient as IQ but almost half the price initially and then upto 70% less expensive for filter replacement. Then we found out that ALEN was built upon the premise of making Premium Air Purification Affordable and when you have 6 units in your house you need to really think about cost-effectiveness.
The filters are cheap to maintain the Lifetime Warranty for the safety and relief we have been feeling for 3 year now. Way to go ALEN for thinking way ahead of the problems we are facing today in Asia.
Seems like someone did their homework. Nice post! But I believe fine particles should be under 0.03
hi i am looking to buy an Alen A375 air purifier for our new apartment, how long in advance should I leave it in the new apartment before we move it, so that it is safe for us to live in? Thanks
Since people today spend most of their time at home or in an office, long-term exposure to VOCs in the indoor environment can contribute to sick building syndrome.
In offices, VOC results from new furnishings, wall coverings, and office equipment such as photocopy machines, which can off-gas VOCs into the air.
Good air purifiers like the Alen A375UV are helpful at reducing VOC emissions indoors. Its great that you are considering air purifiers because studies also show that leukemia and lymphoma can increase through prolonged exposure of VOCs in the indoor environment.
Paint emissions can continue for extended periods of time after application and its estimated that less than 50% of the VOC's in latex paint (applied to a surface) are emitted in the first year.
Not to scare ya..just the facts. You might want to check what type of paint you used and it will be my pleasure to do further research on your behalf.
I am not sure what type of paint they used for the new apartment. Will try to find out later. Thanks for the info. By the way, my living room is about 70sqm but it is more like a long corridor shape, and connected to my kitchen, do you think one A375UV will be efficient enough for it, where shall I place it would make it perform the best?
Make sure you open your windows a few times a week as well to flush out the toxins.
I recommend placing the air purifier closest to the area you will be spending the most time in. 1 A357UV should be enough for that area just as long as its an open space with no L shapes or closed rooms.
If an air purifier is used, why do you need to open the window to flush out toxins? What kinds of toxins are you referring to?
Most of these air pollutants are outside, do I want to open my window to let the air in?
Above we we're talking about VOC gases from new paint. This is the reason we we're saying it was good to open the windows and flush them out and use an air purifier when the windows we're closed.
If outdoor pollution is the main concern keep your windows closed run the air purifiers 24 hours a day. Open the windows a couple time a week to change the oxygen and you will be living a much healthier life knowing your breathing clean air.:)

Alen Air Purifier for sale. About 2-3 years old. Works great to filter out pollutants in the Hong Kong air. This purifier is top of the line air purifier. Price is $3000. New ones sell for about double. I was diagnosed with Asthma last year and went to hospital with pneumonia last summer. This filter seems to have helped a lot with my symptoms.
If you're interested, please call 6699-3436.
Disclaimer: I have no affiliation with Alen Air Purifiers or their sales agents in Hong Kong. I just want to share my experience with the products I have purchased (1 each of the Paralda and the A375) about 3 weeks ago.
Background: I have 2 daughters aged 2 and 6. My 6 year old has had a chronic cough for quite some time and a few years ago our doctor diagnosed her as pre-asthmatic. Various inhalers (Ventolin, Pulmicort - parents of kids with the same cough will know exactly what these are) have been used to little effect. Medicine from a traditional Chinese doctor made my daughter gag - not effective since she can't even get it down. I had been considering a purifier for a while but considered them expensive and after following this thread for a while I was not convinced that they would work. However, being at the end of our rope I decided to give the Alen units a try.
This next part you may choose to believe or not: After a couple of weeks of severe coughing, the first night my daughter slept with the Paralda in her room (after running it full speed for a couple of hours before she went to bed and then switching it to low) her cough practically disappeared. Perhaps this was some kind of coincidence but her night cough has largely gone away. She does still have occasional bouts of coughing but nowhere near the severity as previously. Also, when she manages to sneak into our room (with no purifier) to sleep during the week-ends, her cough is worse. You may say that this is because we simply notice it more because she is sleeping beside us but she sleeps in the room next to ours and we can always hear when she's coughing (resulting in either my wife or me getting up to get her some warm water - practically a nightly experience before).
Like I said, I have no affiliation with Alen Corp., and you may choose not to believe this and I certainly have no issues if you don't. All I know is that my older daughter is sleeping much better and I thought I would share my experience in case anyone else is in the same boat as I was in.
Stop the zealous air conditioning
This air con-addicted culture is not only killing Hong Kong’s streetlife, it’s damaging the environment, too. After all, most of our power comes from coal-fired power plants, and the more air conditioning we use, the more we pump pollution into our air.

Quick questions. I heard that your bedroom model the Paralda will have the option of a carbon filter soon. True?
Hong Kong’s Idling Vehciles Are Ramping Up Pollution
The idling vehicle thing is a perfect example of local, perhaps even Chinese poltical culture at work. Drives me mad frankly.
takes them years and years to pass the law and then another decade to finish effing it up so badly that of course it does nothing to solve the problem and does not work at all. Cabbies make too much money and have too much influence as well. I hate all the private car owners too but they arent the problem here.
but it retains the appearance of being a law. :-(

Alen Air Purifiers Battle IQAir
We’ve just survived yet another winter night with the US Embassy’s air pollution AQI maxed out “beyond index” over 500, so it’s again a good time to review one of Beijing life’s unfortunate necessities: indoor air purifiers. In our expat world’s never-ending discussion of the best air purifiers, many of you have read my article detailing my head-to-head battle of IQAir 250 Pro versus Blueair 501. Now we can add a third player in my personal tests: Alen Air.
Alen Air is a Texas-based company which makes air purifiers, and a couple months ago their local rep invited me to test out (not keep!) two of their machines at my house: their flagship A375UV machine, and also their Paralda unit. So I spent a couple days comparing these brand-new machines with my trusty stalwarts, my IQAir and Blueair.
And you thought Hong Kong pollution was bad...

Your page does not focus on really tiny pollution particles - http://www.alencorpasia.com/Articles.asp?ID=136
Talking mainly about 0.3 microns & above is somewhat irrelevant here in Hong Kong .
We seem to need much finer filtration than this to really protect our health here.
Pollution hits Hong Kong economy
good article ed. I thought the exact same thing when the HK government announced the $6000 handout to permanent residents scheme. Are you kidding me??? Is is really more important or better to hand out cash to residents rather than spend it on environmental issues like updating old diesel vehicles?
Sadly, the ONLY way Hong Kong will ever deal with the acrid air is if it effects the region financially. Hong Kong speaks only one language and that is money.
That is true but I am not holding my breath ... as the gateway to China HK has been booming... and talking to recruitment firms... the pollution is having minimal effect on business.. yes, some candidates turn down HK opportunities but there are plenty others lined up to take positions... and with continued high unemployment in the US and EU, there will be no problem finding qualified people willing to breathe this 'air'...
Bad Beijing air quality during holiday
Air pollution in Beijing reached hazardous levels again this week, but the push toward openness about what's in the air continues. Until recently, officials refused to release information about small particular pollution — potentially the most dangerous, unseen ... full story

Hong Kong Is Choking, Too
This article / quote below highlights my confusion.
You are enthusiastically promoting these air purifiers here - but they seem to be inadequate to really deal with the air pollution here in Hong Kong.
Your own website agrees that you have not measured whether do not remove fine particulates which are hurting myself & my friends.
Excerpt - + ....."Ultrafine" is a term reserved for particulate matter smaller than 0.1 micron (100 nanometers) in size – particles that are on a nanoscale. The EPA sets standards for the maximum amount of PM2.5 that can be in the ambient outdoor air with the goal of protecting health. Cities and states must then comply with these standards. The EPA has not set any standards for the smaller, ultrafine particles.
However, an emerging body of research shows that these ultrafine particles are just as dangerous – and possibly more so – to circulatory and respiratory health as PM2.5 particles. +
The 'Edit' function is not working.
Your own website agrees that you have not measured whether or not they remove very fine particulates which are hurting myself & my friends.
all HEPA filters (which were invented/designed in the 40ies to remove radioactive particles from the air (Mantattan Project) ) have to remove 99.97% of particles greater than 0.3µm from the air.
The Alen filters do that, and in a affordable manner. I personally did a Laser particle counter test on my first Paralda, before I decided to buy for the whole house and yes, it works. I published the results earlier in this thread ...
(a search on this page for "230,000" without the "" will get you right to it)
They are not perfect, they partially re-breathe the filtered air (why was it designed that way? to make the particle count at the exhaust look better or what?), the UV lamp makes the plastic mesh over the filter paper disintegrate after a while, they are noisy .... I could go on.
But, as I said before, they do what it says on the tin. And that, after all, is what counts...
If you want better filtration you'll have to go with IQAir, which can remove particles up to 0.1µm, but cost 12000$ upward the piece.
And the only way to avoid the particles under 0.1 µm is to move to the Swiss Alps, I'm afraid. No filter system on the market for home air filtration is that good.
Welcome to the world of air purifier marketing. Alen and many other brands that use good Hepa filtration can filter down to 0.1 microns due to the “Brownian Motion” effect on hepa filters. The difference is certain brands went out of there way to test it so they can use it in their claims. Just google this and you will competely understand why and the science behind this.
At the end of the day whether your purchase a brand new Volvo or a Mercedez both will get you and your family from point A to point B safely with very different price tags.
We are going to start home air quality tests in Hong Kong very soon and are more than willing to prove performance.
A prominent unbiased doctor in Beijing has tested the the leading brands and here are his findings. He also also posts great information about pollution.
China Pollution Visible from Space!
It would be great to have clean air in Hong Kong.
However, if every household in Hong Kong would use one or more air purifiers, the the general air quality would be a lot worse. As long as the air-purifiers need electricity, the power plants will go full speed and produce a lot worse pollution than we gain from cleaning it.
A bit like having a fridge open to cool down your flat... It just doesn't work!

Hong Kong’s Killer Pollution
Letting all Asiaxpat members know that Alen Air has now officially lauched its free air quality assessment division in Hong Kong.
This means that an air quality specialist can visit your home or office to test the air quality with a laser particle counter.
If you have been unsure how bad the air quality actually is, this is a good chance to see your own indoor pollution levels as well as see a before and after test using an Alen air purifier. The testing time and product demonstration take approximately 30 minutes.

Clean Up Effort for Hong Kong Port Hits Rocks
In 2010, Hong Kong’s government—long criticized by activists for failing to clean up the city’s iconic Victoria Harbor—was handed an extraordinary corporate gift. A group of 17 cruise and shipping lines volunteered to begin burning more environmentally friendly fuel when berthed in Hong Kong’s waterways, at no small expense to their shareholders.
Now, though, as the shipping industry reels from billion-dollar losses, the future of that agreement is on the rocks. http://blogs.wsj.com/chinarealtime/2012/03/26/clean-up-effort-for-hong-kong-port-hits-rocks/?mod=google_news_blog
My favorite is when tourists go up to the Peak......they have to take pictures of the 'pictures' being sold at the gift shops because the pollution is so bad they can't see across the harbor :)
Shop owners should charge tourists for taking pictures of their pictures...
Hong Kong’s Killer Pollution
I am thinking of returning to HK but with 2 kids now... It's a little scary. Ed, where do you think is best for parents with kids (in HK). We're currently in Toronto and there's pollution here too. Lots of buildings going up downtown and lots of traffic. Aghhhh! What to do.
If you are bothered by the pollution, construction and traffic in Toronto....don't even think about coming to Hong Kong. HK is ten times more polluted, congested and noisy than Toronto. Stay put.
Traffic... NOTHING is worse than the 401 in rush hour... so I wouldn't be too concerned about the traffic... you can get around it using the subway...
As for the noise, crowds etc of Hong Kong... that's what makes Hong Kong what it is... if that's not your thing then shuffle off to Singabore... (or suburbia)...
Hong Kong island, particularly the areas near Central, is like jamming chaos into a pressure cooker - never a dull moment - I LOVE IT.
That said there are plenty of oases of calm in HK if you wan to escape the 'buzz'... loads of hiking in the parks and outlying islands. Stanley is great for a weekend chill out brunch...
As for the air pollution the best place is Shek O... problem is its far... and its very difficult to find apartments for rent (very small place)... alternatively Discovery Bay is good since there no vehicles ... Lamma Island is also a good option...
At the end of the day you spend most of your time in your office or home... so it doesn't matter too much where you decide to live...
But one thing that is crucial is that you install quality air purifiers in both... it makes an ENORMOUS difference...
We've got Alen in our office and my brother has them in his home where I often stay when I come to HK...
Before installing these he was constantly having eye allergies related to the air pollution - that cleared up when the machines went in...
As for me, within a day or so of arriving in HK I would start to get a minor but irritating respiratory allergic reaction to the air ... I'd seen a doctor about this and he said the only thing you can do is take antihistamine...
Since those machines went in I no longer experience this reaction - and I spend more time in HK because of it.
In all seriousness, everyone in HK should have an air purifier in their home and office ... the two best are Alen and IQ... Alen is a third of the price...

No Easy Scapegoat for Hong Kong Pollution
No Easy Scapegoat for Hong Kong Pollution
In order for the Hong Kong community to have a more realistic idea of true pollution levels, we will begin posting particulate readings from our particle counter throughout Hong Kong.
Our Particle Counter measure the number of fine dust particles per liter of air at 0.3 microns (one millionth of a meter).
It does not measure exactly what is in the air, such as mold spores or dust mites, only the total particle count.
For reference, the Swiss Alps average around 3500 particles at 0.3 microns.
The average in a place like Canada would be around 30,000.
According to the World Health Organization, with under 60'000 particles no negative health effects are to be expected.
At around 100,000 it is considered inadvisable to run outside. Over 300'000+ particles can lead to irritations of the respiratory tract, coughs and headache.
The frequency of asthma attacks may increase. The highest recording of the year was over 1,000,000 particles on April 13th in Central.
The lowest particulate reading in the past week was 1485 at a Alen A375 users home on Kennedy Road in Mid-Levels. The highest recording was 486,245 outside our office in Central.

Memo to Hong Kong's new leader: must clear the air
HONG KONG (Reuters) - As Hong Kong strives to consolidate its reputation as a financial hub and major offshore conduit for China's wealth, the smog that often envelops its skyscrapers exacts a heavy cost.
According to the Clean Air Network, a local nongovernment organization, Hong Kong's air pollution mortality rate is eighth-highest in the world, far worse than the mainland, India and Vietnam.

Well... the deeper you go the cleaner it gets... I think what they should do is install one of those double sealed doors like you have on space stations...
You enter... the external door closes... the Alen Air Machines clean the air in the chamber... then the inner door opens and you then enter the subterranean paradise...
im interested in purchasing a unit but they're quite expensive here compared to US. if i purchase one in us, will the voltage difference affect the performance of the machine?
or if i cant wait to get fresh air in my home and decide to purchase a unit here in hk, will i be able to take this back home to US and use it? if i go to the alen office in central, will i be able to pick one up right away or is it by order only? where can i go purchase one immediately?
anyone interested in buying a unit? i have a group that is ready to purchase 3, but if we get a 4th buyer, all of us get 15% discount.
I would also like to purchase a unit. Please let me know if you have already purchased / will do to qualify for the 15% discount. Thanks.

Hong Kong hit by severe air pollution
Hong Kong is experiencing severe air pollution, with the roadside station in Causeway Bay recording a peak level of 202 this morning.
Readings taken at Central and Mongkok have reached highs of 182 and 146 respectively.
Several general stations have also recorded very high levels.
The government advises people with existing heart or respiratory illness to avoid staying in areas with heavy traffic.
Everyone is advised to avoid prolonged stays in areas with heavy traffic and to reduce physical exertion in such areas as far as possible.
A spokesman for the Environmental Protection Department, says light winds mean the pollution is not expected to subside for a few days.
Not long arrived in Hong Kong. I was really suffering from the air pollution and found Alen Air purifiers online. Bought one of the bigger ones (A375UV) for my apartment. Now feel a lot better. Service was excellent. Highly recommended. http://www.renaud.hk/Air-Purifiers-Hong-Kong-s/65.htm
Pollution levels at over 400,000 at 0.3 microns in Central today. Well over WHO standards.
Please check out the Clean Air Network http://www.hongkongcan.org/eng/ They are an independent NGO. Our mission is to amplify the voices of individuals, groups and organizations and together urge the Government to take the appropriate measures to clean our air immediately.
Even with the wind and rain, pollution levels at over 550,000 at 0.3 microns in Central today. Almost 10 times the healthy WHO standards.
Here is a great website that measuries Hong Kong's air pollution costs
The Hedley Environmental Index monitors and publishes in real-time the economic costs of Hong Kong's air pollution in terms of public health impacts and their monetary value. The public health impacts include premature deaths, hospital bed-days and doctor visits.
