WHAT IS 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® 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.
