Then there are these so I am really in a tizzy as to what to do.

Performance Test Results - Large Room Air Purifiers
Recommendations: Air Purifiers America highly recommend the IQAir, Alen or

BlueAir air purifiers as these units remove over 98% of all air borne particles such as pollen, mold, dander and dust. Air Purifiers America does not recommend the Friedrich C-90, Ionic Breeze or Oreck XL air cleaners as these units generate ozone which is harmful to the body according to laboratory research conducted by California DHS' Indoor Air Quality Program.

The air purification technology in the EdenPURE™ is that used by the federal government to purify air in the Space Shuttle and the International Space Station.

Oreck Air Cleaners Use the same technology as that found on U.S. Navy submarines.

IQAir Beats Them All Out!
Hey All,

Air purifiers really have been an issue of confusion for many years from a performance and quality standpoint. Every company pretty much touts that theirs is the best. A prime example is the Ionic Breeze. That machine sold millions and millions of units and it turns out that it was utterly useless. In fact Sharper Image, the primary pusher of those, has not only gone bankrupt but they also lost a $50,000,000 class action lawsuit brought on by the hundreds of thousands of people that bought that junk.

I have done a great deal of research on the subject of air purifiers. After a lot of reading and also a tremendous amount of testing, all my research kept point to IQAir. I firmly believe that they by far are the most exceptional manufacturer of air purifiers. They are German engineered and Swiss made. Their machines truly produce zero particles. In other words, what comes out is 100% fresh, clean air and nothing else.
Anyone who really wants the best of the best has to look into their product line. I bought the HealthPro Plus model which contains 3 filters including 5 pounds of activated carbon.
Highly recommended.

May I install my 2 cents worth. I own two (2) Hunter Brand room type air purifiers. One of the units has the electronic grid that I think is supposed to somehow make the air cleaner (tells you how much I have used it). These units were bought at Lowes in my hometown. My problem>after about three(3) years Lowes discontinued selling the Hunter units. Now, where do I buy replacement filters? The closest place I could find was something like "Service Merchandise" in Tallahassee, FL., but they went out of business within that next year. So- -I called Hunter and convinced them to sell me the filters if I would buy six (6) of each size at a time. The filters will last me two monts easily, Hunter may not like this but I do. These are quite expensive but, the units are good and the cost of replacing them was high also. Thes units do help keep the dust down in our house. My advise>look into a unit that you believe you will be able to find filters and/or parts for over the next few years. Thanks, David

I've used the Austin Healthmate , you get what you pay for

seawiz 02-22-2010 09:25 AM

You definitely get what you paid for, but after a few hundred dollars you start to hit a point of diminishing returns. Something for like $100 won't be as good as something that is maybe $300, but the difference between a 300 purifier and a 500 one would be less than the difference between the 100 and 300. That being said if consumer reports has a cheaper one by a couple hundred than some of the others I would go with that. Why spend more unless you really need something a more pricey model has?

Best Air Purifier
You have done your research! Of those you listed, I like BlueAir Purifiers the best. I don't have one, but my cousin does and when she was pregnant and her home was full of toxic fumes and dust from their remodel project, she had the purifier running in the bedroom and the air was dust and odor free. It was amazing. Also, they are energy star rated and won't cost as much to run. The other brands you listed do not have as high quality HEPA filters and air processing, which is why they are cheapter. The best cheap one is the Honeywell 50250.

These work and are cheaper then standard purifiers
Ozone Lites - I use them in my basement by my cats litter boxes, and the nightlights I use in my kids rooms. I've seen a bunch of posts asking if these actually work. They do!!

air purifers
When buying air purifier for your home keep these in mind:
- Affordability
- Noise
- Efficiency, do they only remove certain pollutant inside your home?
- Ease and cost of filter replacement
- Is it for the whole house or a single room
- Ozone production
- Warranty

My Mother was one of those people that bought an IONic Breeze many years ago. She still uses it and cleaned it every week. The fins are always full of crap, so we always assumed it worked.

What are you saying that it doesn't do? And where does she get some of this $50million?

Myself and my wife recently purchased a brand new home in a new build development where most of the house's are still being built around us. Not only is the noise of the construction work annoying, but the dust in the air in and around
our neighbourhood causes my asthma to flare up at a worrying rate. And this was worsened further when there would be a storm in the area, even with all the windows sealed tight, the general quality of the air around us was seriously reduced. So out of desperation and alot of research we decided to invest in the AQAir Health Pro Plus purifier. Yes its an expensive (and large) piece of equipment, but its done absolute wonders for our home and general quality of life.

Several months later, even with the construction work now over, there was still the large storms to consider, blowing dust and other random junk particles around the area, but now we have the purifier this isnt even a concern. I have a blog up at

To purchase the most appropriate air purifier for one's personal needs, it is important to know what is causing the allergic reaction. Is it a reaction to particles in the air, such as pollen or dust, or is it a reaction to gasses or airborne chemicals? Different air purifiers address different causes.

I had to explore the many kinds of air purifiers when our son moved into an apartment in Los Angeles where he was affected by the residue left by the air conditioner, exhaust fumes and particles that came in when the windows were open, and also by the off-gassing of chemicals from a new micro-suede couch. The Air Wellness Power5 solved all his problems. I started a website to address this because i have met so many people with similar challenges:

I personally use Honeywell, I believe it's the best manufacturer so far. Their ozone purifiers do their job just greatly. If you want to choose what type of air purifier is suitable for your needs: ozone, ionic, HEPA, UV, carbon, or any other, you can check a chart here:

Austin Air HealthMate also for me. We've been using it for years.

sparklepools 11-03-2010 02:17 PM

I have an Austin Air Health Mate Jr. listed on ebay for a great price. I've had it for awhile, but never used it. It's in new condition. Here is the link:

Air Purifiers - Most people get teh wrong type of filter.
As a technician a lot of people ask me about air purifiers and the best one is really the one that fit's the room size and problem you have. Some are good for dust,and many aren't, while others are good at dust - yet bad at mold.
The following site was helpful to me - with videos about which filters do what and independent (objective) reviews and lots of info.
