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.
Note: This air cleaner is suggested for use in a single, closed
room up to 335 square feet. Portable air cleaners will be much
more effective in rooms when all the doors and windows are
closed.
Tested per ANSI/AHAM AC-1 National Standard.
