IQAir - Cleanroom H13

You will always need at least one purifier per room. IQAir doesn't provide Clean Air Delivery Rates (CADRs) due to their objections regarding the AHAM AC-1-2020 standard's testing limitations. Instead, they use "Air Delivery". IQAir recommends the following calculation: Air Delivery setting (in CFM) × 60 ÷ Volume of the room (cubic feet) = Air Changes per Hour (ACH). So if you use the Cleanroom H13's top speed setting with a hypothetical room volume of 2,400 cubic feet, the calculation is: 360 CFM × 60 ÷ 2,400 cu. ft. = 9 ACH. 2,400 cubic feet of room volume would be 300 sq. ft. with an 8 ft. ceiling. The Cleanroom H13 has a very large combined filter surface area: a 75 ft.^(2) pre-filter + an 81 ft.^(2) HyperHEPA H13 Filter (F2) for a total of 156 ft.^(2). This means you probably won't need to replace the filters for a very long time, although this depends on your apartment's particulate pollution levels. [Here's a link to the tech specs sheet](https://cms.iqair.com/sites/default/files/documents/Tech%20Specs_CR%20H13%20NE_120V_130723.pdf). But keep filter costs in mind. The Cleanroom H13 [pre-filter is $179.99](https://www.iqair.com/us/products/replacement-filters/premax-pre-filter-f8-xl-f1) and the [HyperHEPA H13 Filter (F2) is $289.99](https://www.iqair.com/us/products/replacement-filters/hyperhepa-h13-filter-f2).

The Cleanroom H13 has a higher top Air Delivery of 360 CFM, doesn't use any gaseous filters, has more total filter surface area (for particulates), and its main particle filter is H13 HEPA. It's also registered as a U.S. FDA Class II Medical Device and weighs more than the HealthPro Plus. Per the EN 1822-1:2019 standard, H13 and H14 HEPA filters are leak tested. If you look at this photo of the Cleanroom H13's [HyperHEPA H13 Filter (F2), you can see it says "LEAK TESTED"](https://cdn.shopify.com/s/files/1/0065/4780/0182/files/HyperHEPA-H13-F2_Filter.jpg).

Most air purifiers produce more of a rushing air sound, which is different to a large fan. And many can be quite loud on their top settings—examples are IQAir, most Medify Air models, and Winix. You could [build your own Corsi-Rosenthal box](https://engineering.ucdavis.edu/news/science-action-how-build-corsi-rosenthal-box), which is powered by a box fan. See also the related subreddit: r/crboxes If you want to listen for yourself, you can go through HouseFresh's YouTube playlist of air purifier sound tests. A few models may not be available in the USA or have been discontinued.

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.

IQair is the best. Blueair are made in China and mostly emphasize on looks

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.

Yeah, this is mine as well. 10 year warranty, Swiss made. It’s the only place my family can be when the allergies get really bad.

Wow, I didn’t know!! Thank you for explaining that. Costco had a good deal for shark air purifier and I was considering it. I have one IQ Air but their customer service hasn’t been great and the machine is really bulky, old fashioned with a hefty price tag. I was attracted to cheaper options but I’d get what I paid for it sounds like.

I have Austin Air and IQAir…both terrific. Expensive.

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!
