Clean Air Delivery Rate:

What is CADR?

The Clean Air Delivery Rate (CADR) of an air purifier is the measurement of the volume of filtered air that is delivered by a portable air purifier. CADR is determined by a uniform standard, and the ratings describe how effective the purifier is at reducing three common indoor air pollutants: tobacco smoke, pollen and dust.
