Which air filter rating should you trust?
here are several air filter rating systems. This can make it difficult for consumers to know who or what to trust. Learn about the different rating systems, terminology, and the pros and cons, including Clean Air Delivery Rate (CADR), room-size, HEPA, “True HEPA,” HEPA-type,” “HEPA-like,” “HEPA-style,” “99% HEPA,” “HEPAsilent,” and HyperHEPA.
The CADR rating is meant to be a standard represented by a numerical value that allows consumers to measure the effectiveness of stand-alone air purifiers (CADR ratings are not used for whole-house systems).
