Clean Air Delivery Rate (CADR) is the number of cubic feet of clean air that an air-filtration system delivers in a minute.
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 inch throwaway that’s found in 85% of homes, has a CADR of 10. In contrast, the Trane CleanEffects® Whole Home Air Cleaner has a CADR of 1200. For example, that means the Trane CleanEffects® Whole Home Air Cleaner 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® Whole Home Air Cleaner.
