Understanding CADR
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 the air purifer is at capturing fine
particles. Higher CADR rates indicate improved performance
in all room sizes.
