Hello All,

High Efficiency Particulate Air (HEPA) filters are the base minimum you should be purchashing however TRUE HEPA FILTRATION is used when you wish to remove 99% of all airborne particles which are less than 1 micron in size.

I human hair is 60 microns in diameter!

TRUE HEPA FILTRATION in the ALEN Paralda removes 99.97 airborne particles therefore 0.3 microns or larger which captures dust, pollen, mold and other microscopic particles.

Now that you have elimated the finest particles, improving your air quality to the highest levels you have increased your respiratory health to a PREMIUM Air Purifier Level!

ADD the feature of a UV (Ultra Violet) Light and you can tackle Bacteria which range from 0.2-5.0 microns and the ALEN Paralda has been found to remove 99%. These are the same levels used in hospitals and also for those really concerned about H1N1 and 50% of all other viruses that cause the FLU!

ADD the On Demand IONIZER and ALEN Paralda can produce 1 Million negative IONS per cubic cm if you suffer from respiratory allegies and headaches.

ADD that the ALEN Paralda is the First LEAD FREE, ENERGY STAR Qualified and OZONE SAFE Air Purifier on the market today with a LIFETIME WARRANTY and you can now see why ALEN is America's #1 Air Purifier!

NOW AVAILABLE IN ASIA with SE ASIA HQ in KUALA LUMPUR!

Hello All,

I've been reading many comments here and concerned many of you are missing the important points of what is key to consider in your first Air Purification purchase.

Dont become short sited with initial price as these units (at least the well appointed ones) have the latest technology, TRUE HEPA filtration, are tested to perform where you need them most and if high quality will last for many years.

In my experience, any Air Purification System that is not TRUE HEPA and tested independantly or awarded as such should not even be considered in todays environment, especially with many airborne viruses, bacteria and mold spores which are less than 1 micron in size.

Not surprising given the above challenge for cleaner air in our homes and protection of our family, especially younger children, that there is over 800 different models in the AP market worldwide right now.

In reality, some of these actually work! In reality, very few of those will filter out the harmful airborne particles which are most important so if you take one of these home, run them, and feel absolutely nothing is happening, likely it's true.

IMO, you have a responsibility to research any purchase very carefully especially one of this kind which like clean water or safe food is as important.

I see many brand names mentioned in this blog who seem to get your attention through smart marketing, but where are they in their claims or independant tests. Better yet, try calling them and requesting this information before you have made a decision.

I would rather pay for something which does what it claims to do, and very well given it's importance, then to pay ANYTHING for something that makes none to very little impact to my health.

Another nice piece of press for SHARP! I can submit from my own experience that I felt no difference using their highest priced unit, around $2000 RM in Hong Kong last year. This unit was purchased as my wife had been suffering extensively from the pollution.

I decided to spend the extra on the most affordable PREMIUM AP in ALEN.

This is also the first instance I have heard any hospital actually bringing in a NON-PREMIUM AP.

SHARP has done a good job in their marketing for sure but again lack the fine particle filtration and the documented approved independant lab testing to confirm their performance as using TRUE HEPA filtration and being part of the PREMIUM segment in which only 3-4 brands qualify.

If you wish to protect yourself the best way possible, start with TRUE HEPA Filtration which clearly has been tested and performs to a 99.97% of Airborne contaminants.

Furthermore, go with brands which focus on Air Purification ONLY, not one's which build every electronic product under the sun!

I recommend that anyone who is doing their homework understand that the AP business is relatively new and very congested given it is unregulated. In this case the marketing giants have their day but at the expense of your own personal health. Some do work, some dont! The one's which do work only to a certain level.

As always buyer beware, educate yourself and buy the best Air Purifier you can afford given the value it delivers. Those can be found ONLY in the PREMIUM segment in which only a few exist. Two of these brands are available in Malaysia and SE Asia.

Thank you for the note. I have never stated that SHARP does not make an AP that doesnt work, on the contrary, they have a strong market share, great marketing campaigns and attractive price for what they offer which is a value to mid priced AP's. I've even owned one of their top models a few years ago but it again clearly made little difference in helping my wife.

Many are moving up to Premium AP's as they do make an obvious difference and are designed and tested to a much higher standard.

There is one MLM company in Malaysia offering a premium AP however it starts at over $5000 RM with annual filter fees of over $1000RM.

There is another Premium AP in town which can not be disputed as one of the best AP's on the market today but starts at $4400 RM with annual filter fees of $800-$1200/yr.

My responsibility will be to those who are looking for a Premium Air Purifier at finally an affordable price which is America's #1 Air Purifier Now Available in Asia!

Yes, it's rated #1 Best Air Purifier by Consumer Research, Awarded 2009 Respiratory Management Product of the Year, Rated #1 by Air Purifiers America in Performance, Quality and Ease Of Use and is clearly the Smart Choice in the Premium segment in Performance, Initial Price and ongoing costs.

Welcome to ALEN!

Btw, we are proud to also be the First Lead Free, Energy Star Qualified & Ozone Safe AP on the market today!

We are also proud to locate our SE ASIA office in Kuala Lumpur. Our formal launch for both Malaysia & Singapore will be around March 2010 however we have been targeting and selling to those who wish to have our AP's pre-launch via a few channels including those who are well educated on the LYN!

Sure, SHARP seems to have had some testing done since my review some time ago but still lack the results from the leading independant testing labs accredited in the AP segement. I would also recommend you call them direct to try and secure this information yourself so you can make your own correct and educated decision.

Secondly, SHARP offers a range of low to mid market Air Purifiers using their Plasmacluster Technology which is not a Premium AP which must at the very least offer TRUE HEPA Filtration Technology accounting for the smallest of particles and filtertration to a level of 99.97%.

I hope this is clear to readers, as I have previously stated and we can get back to educating those who are looking for the best solution in what seems to be a sea of AP's now on the market in SE Asia.

Added on December 30, 2009, 12:35 amTrue HEPA air filters compared to HEPA type filters

True High Efficiency Particle Arrestant (HEPA) air filters, or absolute HEPA air filters, are those HEPA media filters that satisfy a special standard of air filtration efficiency.

In particular, their HEPA media should capture at least 99.97 percent of air borne particles down to 0.3 micron in particle size.

HEPA type air filters are built by similar principles as the true HEPA air filters. That is, they are paper like media filters that use mechanical filtration to capture dust particles in their narrow passages.

Yet, the HEPA like air filters are not a good replacement for the true HEPA filters in terms of quality (though may cost less). Their media efficiency is often much worse than for the true HEPA filters (as low as 85-90 percent) especially for smaller (less than 1 micron) particles.

The only additional comment to what I have already described from my personal experience about Sharp is that certain people complain about eye and chest irritation which is due to the amount of free radicals the ionizer gives out. Some people notice a smell of freshness in the air but this is due to the artificial purification of negative and positive ions.

While we and others see the value in having the secondary feature of an Ionizer (where low levels of negative ions improve health ranging from respiratory allergy relief to reduction of headaches), we have the option to turn ours on or off to satisfy this while SHARP's is automatic to support their patented technology!

Scientific evidence clearly shows that a hepa filter is the best choice and there is no scientific evidence showing the benefits of an ionizer yet there is a lot of evidence that demonstrates the harmful effects if this is the primary technology being used.

TRUE HEPA is the preferred, HEPA at minimum, but we at ALEN along with other top Air Purification Brands design and comply with both the Governing Agencies and Scientific Community to engineer and develop to the proven technology which has been evolving but in place for decades! Secondary to TRUE HEPA is UV which reduces airborne germs producing a healthier environment. Lastly is the Negative Ionizer to be used as needed.

Also note, that SHARP's actual warranty is shorter than it's filter life which is really a red flag for me...but if you work for SHARP you already know that!

At this point, if you are unable to agree with what has been stated, compared or produced scientifically or independantly, may I suggest we agree to disagree and move on and let those on the LYN decide for themselves.

a few pages back theres a forumer "hackwire" who seems to buy into Alen products....eventhough he has a geeky username, looks like he has fallen into one of the oldest internet marketing technique.

What's annoying is seeing hard working people come to this blog looking to get educated on Air Purification and see little content to understand both the industry, standards, qualities and levels of Air Purification and not getting what they either pay for or expected.

Try Googling ALEN AIR PURIFIERS before you make any such judgements in the future.

And furthermore, dont assume another user on this forum has failed in his/her decision for the best Air Purification possible when these buyers and I have spoken directly, while they have personally exhausted time and effort, chose this product 1st and through only their high interest have brought the product to SE ASIA.

Onemorething is not an agent but the MD for ALEN in SE ASIA. The ability to bring Premium Air Purification at an affordable price to consumers does not support using agents and as you commented can sometimes be MISLEADING with their limited knowledge and motivation.

It is refreshing to see a blogger who knows the industry standards I might add.

To comment on the above, we can agree to the point of the AP market being questionable on a good day. North America has the highest level of regulation in this massive and growing global unregulated market.

To this, the term TRUE or ABSOLUTE HEPA had to be added to the naming convention (messaging and claim) by many of the industry leaders, most of which as described above have 99.97% filtration effectiveness and were concieved for use in operation theaters and pharmacies and later offered solutions to the consumer to handle home based needs.

The Term TRUE/ABSOLUTE HEPA exists only due to the crowded air purifier market which was both claiming HEPA but not meeting the industry standard as described above.

For a filter to be labeled "True" HEPA, it must be certified 99.97% efficient in capturing 0.3 micron (not 0.1 or 0.01 etc..) respirable-size-particles (RSP) according to the U.S. Military Standard MIL-STD-282, commonly known as the DOP test. The reason 0.3 micron is used and no other is because 0.3 micron is the size at which all mechanical filters are LEAST efficient in capturing. Other methods of testing do not give a true picture of efficiencies relative to respirable-size-particle (RSP) capture.

Look for companies who either provide this label on their AP's or can produce the certification to make sure they meet this industry standard!

Here is another good source to explain TRUE/ABSOLUTE HEPA that was recently posted.

True HEPA Air Purifiers
By Anthony J Davis

http://ezinearticles.com/?True-HEPA-Air-Purifiers&id=3520858

You will probably see items that are labeled "True" HEPA if you shop for HEPA air purifiers. So, I'm sure you're wondering, does that mean there's a false one? Of course you would never find a product that boldly proclaimed to be a sub-standard HEPA purifier, but to be called a True HEPA purifier, there are some differences. As with any other purchase, it's left to the consumer to figure out the differences and know if they need to look for one or the other. Let's examine True HEPA air purifiers and why some products may not claim this.

How Are True HEPA Purifiers Different

There is a difference between a HEPA-type air purifier, and a True or absolute HEPA purifier, which is also called an absolute HEPA air purifier. Even if folks do not always make it clear, when they're comparing HEPA filters to other air filtration medium, especially if they're referencing the likes of OSHA or the EPA, they're talking about True or absolute HEPA filters. Yes, there are many types of air cleaners and purifiers available, but the only ones that places like labs and hospitals use are True HEPA air purifiers.

True HEPA Filters Stop 0.3 Micron Particles Of DOOM

Of the different specifications that True or absolute HEPA purifiers have to meet, the most important is probably the 99.97% of all 0.3 micron particles. This stat is incredibly important, and not as technical as it may sound. Of all the different pollutants floating around out there, it's been found that 0.3 micron particles generally are the hardest to filter, even including those that are smaller. They also are the most likely to cause problems in the human body, and have no problem scooting right past our natural defenses. See, 0.3 micron particles are more scary than nerdy, aren't they? If you want an idea of the size we're talking about, compare 0.3 microns to the human hair. Human hair is generally anywhere between 70 and 100 microns thick.

True HEPA Filters Actually Work Better When Dirty

Another big difference between HEPA-type purifiers and True HEPA filters is how they filter when they become dirty. This is where the "Absolute" part of the equation comes in. Any absolute filter media will actually become more effective as it gets dirtier. The more particles that are trapped in an absolute filter, the more effective it will be. The reason why is actually pretty simple. As dirt and other debris builds up around the air holes, those holes get smaller and smaller, allowing less to get through.

Is It A True HEPA Air Purifier? How To Know

Look for products that actually advertise that they are True or absolute HEPA air purifiers. The alternative is the HEPA-type purifier, which is really just an imitation, and is not held to any particular standard. If you find a purifier that doesn't say either HEPA-type or True HEPA, you can also reference other specifications on the box. Look for one that filters 99.97% or more of the 0.3 micron particles if you want a True HEPA air purifier.

Hi Saykong,

If you have found airpurifiersamerica.com then you have found likely the top independant resource for Air Purification reviews today.

They are one of few which have both a test facility and industry aligned bench testing processes and methodology putting all brands and products to the real test first and foremost in support of both their filtration levels and claims.

I'm not sure why the SHARP models were not tested and will try and find out however the top 10 are in fact PREMIUM Air Purifier Brands and meet very high levels of Air Filtration Performance.

i think you need to explain yourself here.
while we appreciate your time to share your knowledge, i think you should be more truthful earlier.
from your earliest posts, you seemed like a consumer (with your wife having problems then Alen purifier saved the day when others can't).
And you were promoting as an consumer even going as far as giving news of Alen coming to SE Asia.
now, you say you are the MD for Alen?
sounds like a conflict of interest to me and you deliberately made a big round before declaring yourself as an MD.

i am not saying you are misinforming ppl but i think you shouldn't bash other products and not expect ppl to careful who they are listening to.
*
It is quite easy to explain, I'm both and it was only the through strong consumer research and challenges for clean air at home that brought me to ALEN after doing years of research. It was during this very short time that I was formally appointed as the MD. I could not declare myself as that person until recently.

For a consumer to get good information, on which AP is the right choice for their home, they must unfortunately suffer through hundreds of claims and choices. My information is intended to articulate & educate the consumer of different technologies used in competing products to ALEN.

I encourage any interested consumer to do their own research overall but most importantly the difference between a PREMIUM AP and the others on the market today.

Let's face it, the real test for an AP comes after you have made your purchase and if you can really FEEL the difference in your health and well being. I am sad to say that most have little or no positive effect. Some builders cut costs in design or quality that effect long term performance. Some technologies require careful usage or cleaning and maintenance to keep up a level of efficiency and not have adverse effects to your health. If you believe in HEPA filtertration, in which the leading industry brands do, how do you know that product meets the qualification of both HEPA filter AND matching the claims when the unit is running.

I hope this clears up our position of WHY we are providing input for the LYN readers and where we stand on Air Purification. We hope that your decision most and foremost will not take you down the long winding and confusing road of choosing an AP and that the information provided will in fact assist in your seach.

All the Best!

Nice to see posters are getting educated on HEPA and more importantly the PREMIUM offering which are known as either TRUE or ABSOLUTE HEPA.

Be sure to do your homework which includes reviewing all the test reports and customer feedback on these.

TRUE HEPA + UV FILTER + ON/OFF IONIZER + OZONE FREE + ENERGY STAR + LIFETIME WARRANTY!

While replacement filters are an ongoing expense, none of the top PREMIUM AP's have reusable filters as these filters in the first place will never filter to 99.97% efficiency add that if reusable filters are not cleaned properly then it makes matter worse.

Compare this to a water purification system, only the best require filter replacement.

Same is easily justified and understood in the top AP's Globally!

www.airpurifiersamerica.com is the top research site for AP's.

You wont find 99% of the AP's offered in Malaysia there but you will find the top 10 out of over 800 models currently on the market today.

Word of Advise to All...there are over 800 different Air Purifiers products on the market today. It is extremely confusing for most to understand the technologies and be confident with your purchases.

Keep it simple and purchase Air Purifiers from Brands which have been both tested, approved and highly rated by the industry professionals and end users.

This is a crowded space for a reason as we are all very health concious today related to airborn viruses and for some reason more susceptable to numerous airborne particles then ever before.

Dont be fooled by outrageous marketing claims and scare tactics, take the high road and purchase and Air Purifier that is a proven success and spend as much as you can afford initially and you wont be disappointed.

We receive so many calls and email enquiries asking for help in deciding which AP to choose and to be honest there are only 2 brands within the top 10 that are available here in Malaysia.

Many think to reach the PREMIUM TRUE HEPA Air Purifier Level you need to spend quite a bit and you would be correct however if you do your research you will find that ALEN is not far out of reach.

That must be why it's the #1 Air Purifier in America!

Okay so please supply evidence of any formal testing by industry professionals, agencies, reviews by industry professionals or end users!

Anyone can get an independant test done and bench test in a controlled environment! The proof is when you take the unit home, deploy it in an everyday environment and it does what it says it will.

PREMIUM TRUE HEPA Air Purification is the proven way for decades now! Once only available for hospitals and clean room applications, the technology is now affordable for home use.

Why would you settle for less when it comes to your family health!

Great Performance....5/5 Stars July 15, 2009
Reviewer: Terry Parker from Shanghai, China
I am currently using Alen right now and have used IQ Air 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. If my child feels better so does Dad!

I based my decision by reviewing this and can say from a consumer stand point the product comparisons are spot on

Added on March 17, 2010, 12:34 pmverified performance claims 5/5 Stars! December 10, 2009
Reviewer: T. Walther from Mui Wo, Lantau Island Hong Kong
I bought a Paralda in Nov 09 and tested it (during the 30 day return period) with a Laser Particle Counter. (for the tech savvy: a swiss "Particle Scan Pro", detection range 0.3 to 30 micron)

these are the results:
- 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, on 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

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 only 1 hour.

So - it does exactly what it says on the tin, I kept it and I am buying more Paraldas and an A375UV for the rest of the house.

Thank you for clearing that up. I am very glad that we have a (very high, haha) person in the industry here speaking to us but the hard selling for Alen air purifiers gotta stop. Educating and hard selling is totally different.

And I'm not a blogger who knows the industry standards. I am also in the air filtration industry, albeit the industrial side. But I do know my stuff and can spot marketing fluff.
Also, my word of advice to all who are seeking air purifiers. DO NOT CHEAP OUT! In the cheap filter industry, some of the filters can actually cause more harm than good. They have dangerous chemicals in them.

Stick to reputable brands. I would not comment on Electronic brands like Sharp, Panasonic, etc. since I have no faith in them. Look for more specialized manufacturers. AAF, HONEYWELL are brands I know I can trust. SDMCSJ (SJMC) uses HONEYWELL air purifiers so they are probably good enough for you. HONEYWELL HEPA filters are also made in America, a country I trust to follow standards set up by the industry.

Buy an Alen if you can afford it. They look like they are really well made, especially the fan,  but of course you must 1st be able to afford it.
Also Onemorething, this statement is wrong.
"Of all the different pollutants floating around out there, it's been found that 0.3 micron particles generally are the hardest to filter, even including those that are smaller."
0.3 microns is actually when the efficiencies of the different filtration principles cross. 0.3 microns is when the efficiency of the diffusion principle is almost the same as the efficiency of the impaction & interception principle.

Smaller particles than that are much harder to filter, hence you have the ULPA filter grade. If what you say is true, this grade is no longer needed. =)
*
Thanks for this information. It's tough to see so many consumers (with limited budget) go out and purchase an AP that is just that "Marketing Fluff" at a low offered price. There is no other way to raise the awareness without a comparative marketing campaign which first dispells the difference between current AP technologies and levels of AP even related to HEPA.

ALEN was only created with the goal to make True HEPA Filtration Affordable for the first time in the industry. Yes, we are slightly more expensive than the Electronic brands however as you mentioned "DO NOT CHEAP OUT!" or you will be very disappointed. This is unfortunately the state of the AP industry today and we are here to change it!

My wording above on the pollutant aspects is a bit awkward and agree with your statement with ULPA filter grade which is the highest level of filtration available today but unreachable by the consumer and most commercial applications. Unwarranted as well. My point is only for those wishing to have the best home based AP filtration, at an affordable price, where the changes in your environment are noticeable, go with a TRUE HEPA filter which is found in PREMIUM AP's and best desribed as:

True HEPA Filtration

High Efficiency Particulate Air (HEPA) filters can remove at least 99.97% of particles 0.3 microns and larger (keep in mind 99% of the airborne particles are less than 1 micron in size — a human hair is 60 microns in diameter). HEPA filters eliminate mold spores as well as bacteria and viruses and of course larger items such as dust, pet dander and pollen from the air.

This is the same technology as recommended by the US Department of Homeland Security to remove harmful airborne particles in a terrorist threat.

nowadays air purifier is a need, not extra things anymore. for me performance of filtration is very important, not a brand.

well said! Just like clean water and quality food, clean air is as important.

O2 Media’s Hit Show Designing Spaces—Kid Spaces Series Welcomes Alen Corporation—Makers of the Paralda Air Purifier!

“Breathing” a Sigh of Relief…

(Deerfield Beach, FL March 2010) On this edition of Designing Spaces-- Kid Spaces, we researched ways on how to breathe in a more purified environment. What we found is-- the Paralda Air Purifier! Alen Corporation—makers of the Paralda Air Purifier joins Kid Spaces to give out some great advice, as well as educate our viewers on how to “breathe” a little easier.

Tune in as Kid Spaces along with Alen Corporation air on the WE network Friday, March 26th at 7:30 a.m. Eastern/Pacific, and TLC on Saturday, March 27th at 7:00 a.m. Eastern/Pacific.

Even spotless homes have microscopic particles in the air that can trigger allergy or asthma symptoms, so cleaning regularly may not be enough. Alen Corporation shares an innovative way to improve air quality-- with the award-winning Paralda air purifier.

The Paralda Air Purifier is a HEPA air purifier—which means it removes particles as small as 0.3 microns. It also gets rid of more than 99.42 percent of airborne contaminants, including pollen, pet dander, dust mites, molds, bacteria—and even viruses!

The Paralda is so effective; it was selected as “Product of the Year” by Respiratory Management magazine. Another huge benefit—is that it also comes with a lifetime warranty!

Don’t take for granted that our indoor air quality is healthy just because we can’t smell or taste anything unusual. By maintaining a higher standard of indoor air quality in our homes and workplaces-- we can empower ourselves to manage our respiratory and long term health.

Hello All, just to repeat an earlier post, if you are looking to do your research on the top Air Purifiers on the market today for home use, which are in the PREMIUM (TRUE) HEPA segment, I would suggest you visit the top researcher/reviewer in the USA. Just an observation, there are only two brands represented in SE Asia right now.

www.air-purifiers-america.com

Take the time to review all the videos. Take the time to calculate initial cost & ongoing costs before you make your decision.

In the meantime, please take the time to get familiar with what TRUE or ABSOLUTE HEPA means to you and your air filtration needs. We run accross so many brands of Air Purification who claim 99.97% efficiency but be warned, this does not mean they operate to this level.

What is a TRUE HEPA Filter?

The Letters in the word HEPA stand for High Efficiency Particulate Arrestance. (You may see others saying that the A means Arresting, Arrestor or Air but they all have the same basic meaning: "to capture") A "True" HEPA Filter is also known as an ABSOLUTE Filter because of it's efficiency!

The "True" HEPA 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 for the transmission of tuberculosis (TB) recommend that only HEPA filters with an efficiency of 99.97% tested at 0.3 microns particle size or smaller be used.

The "True" HEPA filter is recognized by OSHA / EPA as the ULTIMATE in cleansing the air and is a proven method.

The "True" HEPA filtration technology is currently the only type of air purification tool recommended by the U.S. Government’s Department of Homeland Security and FEMA.

"True" HEPA filters are regarded as the best form of air filtration. Hospitals, laboratories, even NASA spend many thousands and even millions of dollars to create contamination free environments called clean rooms to help eliminate foreign particles, infectious agents, heavy metal particles, and a variety of other undesirable contaminants.

For a filter to be called a "True" HEPA, it must retain and filter out all particles from the air that passes through it down to 0.3 microns in size at an efficiency rating of 99.97%.

A "True" HEPA Filters's efficiency DOES NOT decrease during it's life, it actually increases and its also known as an ABSOLUTE type filter media for particle capturing.

For a filter to be labeled "True" HEPA, it must be certified 99.97% efficient in capturing 0.3 micron (not 0.1 or 0.01 etc..) respirable-size-particles (RSP) according to the U.S. Military Standard MIL-STD-282, commonly known as the DOP test. The reason 0.3 micron is used and no other is because 0.3 micron is the size at which all mechanical filters are LEAST efficient in capturing. Other methods of testing do not give a true picture of efficiencies relative to respirable-size-particle (RSP) capture.

"True" HEPA filtration is recognized as one of the most efficient air filtration methods known and proven to remove airborne particles, down to the size of 0.3 microns, and is almost exclusively used in medical, laboratory, and commercial applications where totally clean air environments are required for human health and safety.

"True" HEPA filters are used for nuclear contamination, lead and asbestos abatement, surgical facilities, tuberculosis wards, clean rooms, computer rooms and other areas where clean and particle free air is essential.

Since 0.3 micron size particles are the most difficult size particles to remove from the air (not 0.1 or 0.01 or any other number) and they pass easily into the body's respiratory system, (RSP) they are specifically used in the testing and certifying of a "True" HEPA Filter.

(Please note: "HEPA-Type" filters are lower cost, not as efficient, and not an equivalent to a "TRUE" HEPA filter. "HEPA-Type" filters are simple low cost impersonators of a "TRUE" HEPA filter.)

i'm working in a very small office, the size more/less average master bedroom size. 3 ppl in it. me and 2 partners. no window, just 1 door.

I'm not smoking, the 2 partners is heavy smoker... so everyday I got stress with the smoke... It also affected my health in long run...

If I buy air-purifier will help to reduce the room's air quality in my office?

I think you mean Reduce the pollutants AND Increase the Quality of air in your office.

Absolutely, while there are studies which show inside office air can be up to 10x more dangerous than outside air, adding a smaller office and smokers has to be the worst position you can be in. We just recently did a study and video on supporting the containment of cigarette smoke given the same is true in most of Asia where smoking is allowed in the office.

Please see the following video showing how well we performed.

does it mean there will be no dust in my room ?
Right now after wiping the table i can see dust just after a week.
If i were to ue this does it mean I will no longer need to wipe my table every week?

Running a Premium "TRUE" HEPA Air Purifier will not only remove the large dust particles from your room, but will remove dust mites and fine dust you cannot even see with the human eye. If the room constantly shows dust on surfaces then this typically means you live a very dusty environment.

This can only be caused by outside dust entering in through windows and doors along with the likelihood of your AIRCON system. A dusty environment in general is an unpleasant one and depending on dust can cause very bad medium and long term problems for those occupying the space.

By deploying a TRUE HEPA Air Purifier in your home and specifically in this space, you will notice a major change to the dust you can see and cannot see and find you are also breathing much easier not to mention all the other airborne pollutants it will filter.

Hope this helps.
