	IQAir®	Others
Independent Tests on Entire System	Passed EN 1822 - the toughest HEPA standard in the world - the first portable air cleaner in the world to exceed this test. Our HealthPro Plus captured 100 times more particles than other conventional HEPA air cleaners! Proven to deliver the purest air. Our units are used by the US Military, the pharmaceutical industry, electronic laboratories, and hospitals around the world. Stiftung Warentest (Germany's independent consumer products testing agency) rated HealthPro Plus the best air cleaner for allergen removal. IQAir was the only device out of ten international air cleaners to receive the top mark "very good" for the removal of airborne particulates.	Most have no independent testing on entire system. Some have independent testing using non-standard, invalid tests. Some have in-company tests on filters only, outside of the system and when tested in-system typically results in a 50% decrease in system efficiency. Some are rated according to AHAM CADR - but AHAM CADR is a substandard test. Some are rated using ASHRAE guidelines, which is designed primarily for the protection of HVAC equipment and not for human health concerns.
Individual Unit Certification	Yes - every unit comes from the factory with an individual certification complete with specific ratings per speed and actual output efficiency rating.	Most have no individual certificates
Actual Entire System Efficiency Guarantee at .3 microns or larger	99.97% + tested - certified - guaranteed per unit	Most only give theoretical ratings or ratings of filters outside the system (you'll often see "99.97% filter efficiency", but this is not a total system efficiency rating, it's only a theoretical rating of the filter outside the system). Most do not have an actual system efficiency guarantee - some have rated as low as 50% actual system filtration efficiency output
Actual Entire System Efficiency Guarantee at smaller than .3 microns	99.5% + tested - certified - guaranteed per unit	We haven't found any other manufacturer that will state an actual system efficiency guarantee at particle sizes below .3 microns.
Highest Guaranteed System CFM with Filters	280 +	Usually rated without filters installed resulting in an inflated cfm rating. Ask for CFM ratings with filters installed.
