What is CADR?
CADR stands for "Clean Air Delivery Rate," which indicates the volume of filtered air delivered by
an air purifier. CADR ratings show the effectiveness of how efficient the air purifier is at capturing
fine particles from things like tobacco smoke and plant pollens from the room.
Clean Air Delivery Rate
From air cleaner to air cleaner, compare the CADR numbers. First look at suggested room size. Then refer
to the Clean Air Delivery Rate (CADR) numbers. The higher the number, the faster the unit filters the air.
Refer to website for individual model CADR numbers.
