IQAir - Cleanroom H13

These are the 3 air filters I personally have. Most air filters only get down to 0.3 microns; these get down to 0.003 microns, which captures mold - which is my main concern - as well as viruses, bacteria, etc.  AirDoctor IQAir AirOasis I also have a Levoit that I like but doesn't capture as small of stuff as the ones above.

I can clearly tell when my IQAIRs are running, I sleep so much better. You might already have good air quality Fixing your furnace filter and central filtration will make a bigger difference than buying an air purifier

I keep my IQAir on medium 24/7 and kick it up to the highest setting after housework or during weather advisories (smoke, wind, high particulate, etc). When I lived in the house I was exposed to toxic mold—after I found out about it, of course—I had several (different brand) purifiers on the highest setting 24/7, and though they looked like hell after switching out the filters about once a month, did an extremely good job with professional AQI tests in the interim before the landlord let me out of the lease.

No idea about Merv 16 since I just buy what they have so I don’t have to think about anything, lol, but I use and travel with their car filter—bringing it into hotel rooms and letting it filter in different areas before going inside. Not sure how well it filters all the air in the room, but it’s a relatively small space, so I’m willing to take the chance since otherwise there would be no filtration. I am thinking about buying one of their large round models for the same reason since it would be easier to store at the side of the car instead of a bulky IQAir and would know the filtration would be on point. We actually have two IQAirs: one upstairs and one downstairs. The lower level is far larger than the second level, but they both seem to do a good job, especially on the highest setting (it does an incredible job filtering after-dinner “food smells” from the kitchen, too!).

I run 3 filters, Austin and IQAIR, in each of 2 spaces - one 300 square feet the other 600 square feet. If the air is poor outside my Purple Air sensors will still show green. However there are so many chemicals in wildfire smoke, particularly if structures have burned, that they don't get everything. I am sensitive to terpenes and right now they don't help with the Camphor tree flowers. So they can greatly improve air quality but don't expect all VOCs to be removed from the air.

For best VOC removal, such as mycotoxins, you need a lot of absorbent media. Checkout Airpura, Allerair, Austin, IQAir. All are in the $1k range. I'm unsure whether any filter will eliminate mold sensitivities. Did see an improvement when upgraded my Austins with Immunity Machine filters but molds still aren't totally controlled. There are clinics which can treat mycotoxin sensitivities. Can be quite expensive.

Running both IQAir and Austin Immunity Machines in my major rooms particulates run from 0 to under 10.

I have had my Austin, IQAir, Honeywell and Whirlpool machines for as much as \~20 years and have had no problems with filter replacements.

Alen is excellent. So is IQair

I use mine mostly during wildfire season. Works better than any other units I tried in the past. Got mine directly from IQAir.

Thank you! I purchased a Austin Air and IQair purifier + Miele C3 vacuum cleaner + Mold cleaner for a full revamp. This may be the root cause of my illness which is terribly affecting my quality of life, going all out! Thanks again!

IQAir and Austin Air are the go-to “buy it for life” purifiers. They really have long-lasting filters and proven performance on my end

I consider IQAir to be the top dawg. I have one and a Coway. Both are awesome but IQAir are NOT cheap!

IQAir has been a lifesaver with allergies, pollen and mold.
