Cleanroom H13

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.

The 4 vendors with the best VOC filters are Airpura, Allerair, Austin, IQAir. Absorbent media composition and weight vary by manufacturer. IQAir has models that go up to 32 pounds of media, at least according to google search. Note that no VOC filter will remove all VOCs. They do well with some chemicals, partially control some, and totally ignore others. I use IQAirs and Austin Immunity Machines, multiple units per room unless you want to put up with the noise running the fans on high speed. Had a room repainted and requested a low VOC paint. Was pleasantly surprised that I had no problems with the paint even though I am extremely chemically sensitive. It is possible that the renovations don't cause a VOC problem at all, or maybe just for a few days.

My Austin, IQAir, Honeywell and Whirlpool filters all work with smart plugs. When you purchase make sure you can return if it doesn't work as features change over time.

Alen is excellent. So is IQair

Iqair if you can afford it… I’m sure there are even better in an industrial setting but for home iqair is goat.

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

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 is the way to go.
