Clean Air Delivery Rate

Clean Air Delivery Rate (CADR) is the number of cubic feet of clean air that an air-filtration system delivers in a minute.

That’s a Lot of Clean Air

Recognized industry-wide by retailers, manufacturers, the EPA, and more, the CADR of an air filter can tell you just how hard it’s working. 

The most common air filter, the 1” throwaway that’s found in 85% of homes, has a CADR of 10. In contrast, the Trane CleanEffects™ has a CADR of 1200. For example, that means the Trane CleanEffects™ is filtering all the air in a 12’ x 10’ x 10’ sized room every minute. The next closest air filter is a whole-house electronic air filter, which has a CADR of 660, producing half as much clean air every minute as the Trane CleanEffects™.
