The Clean AIR Center has dedicated labs for filter, materials, and biosafety testing. Advancing the state of IAQ technology is at the heart of AAF’s 33,000-sq.-ft. Clean AIR Center. Engineers put every new AAF filter design through rigorous testing before it is released. Existing AAF filtration products are also tested as technicians look for ways to make them perform even better – including loading HEPA filters with diesel exhaust, a byproduct of delivery trucks that can affect a building’s indoor air quality. Filters that have reached the end of their lives in the field are also examined. The Center’s test ducts meet or exceed all industry standards and use all common protocols. Testing includes ASHRAE 52.2, ISO 16890, and UL 900 with a dedicated UL filter testing room.
