NOTE: Please see more details about this controversy in this post.
Clean Air Kits has published third-party testing data by Intertek, who is able to certify ANSI/AHAM AC-1-2020 standards on CADR.
The test report for the Luggable with the Artic P14 fans only has a CADR of of 189.1 for dust, which is the easiest particle to capture. They declined to publish results for smoke and pollen, which are harder to capture and more dangerous as noted on the Wikipedia page for CADR:
The AHAM seal (usually found on the back of an air cleaner’s box) lists three CADR numbers, one each for smoke, pollen, and dust. This order is from the smallest to largest particles and corresponds to the most dangerous to the least dangerous particles.
The filters used in Clean Air Kits purifiers are typically Filtrete 1900 and while these filters have a fitration efficiency of 95% for dust, they are only 62% efficient for ultrafine particulates. The official CADR values for pollen and smoke for these purifiers would be far lower, however, HEPA filters have efficiencies that are generally comparable for all AHAM CADR categories due to having 99.97%/99.95% or greater for all particles from ultrafine to coarse (DOE/ASME HEPA and EU EN 1822-1, respectively).
The owner of Clean Air Kits has said to ignore the reports for the Artic P14 because they are now using Sicklelflow fans, which are more powerful than the Artic P14. Unfortunately, the results for the Sickleflow are not much better. The Sickleflow-based purifiers only have a smoke CADR of 170 CFM, which is absolutely abysmal compared to other CADR results from the official AHAM database.
False Statements Regarding Filter Performance
Clean Air Kits is publishing false information stating that non-HEPA filters are HEPA compliant and fabricated a non-existant HEPA class “H12” that does not exist. I detailed in this post the problem:
I found some more false information on your website. This purifier talks about a HEPA class called “H12”, however, no such class exists. There is an E12, which as you would know is not HEPA, rather a lower class called EPA that is explicitly non-HEPA grade.
Why are you selling EPA filters as HEPA?
Since you are so litigious, here is standard EN 1822-1 which dictates these ratings (Ctrl+F “H12”, no results). I think you’re just threatening me because you know everything I’m saying is accurate.
| We stock Nyemo H12 grade, Taotronics TT-AP006 compatible filters. H12 grade capture 99.5% of > .5um particles, while H13 “medical grade” HEPA capture 99.97% of .3um particles (at ~5% lower airflow and CADR than H12).
99.5% is not HEPA by either the US ASME/DOE or EU definition (99.97% and 99.95%, respectively).
I think you’re taking “fake it til you make it” a little too far and should stick to doing user interfaces. I’ll remind you that you are posting as a business so I’m allowed to hold you accountable for your bad business practices. I’m sure Reddit doesn’t appreciate you threatening them either.
The owner simply responded to this allegation with:
SmartAir is much bigger than we are. Maybe you should pick on someone bigger:
Intertek Testing Results
The cited reports are as follows:
Rainbow Purifiers - Luggable 16x25 5 Arctic P12 Fan Configuration
Rainbow Purifiers - Luggable 16x25 5 Sickleflow Fan Configuration
I have made copies of all the testing reports in the event that Clean Air Kits removes them from the website.
