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 purifier is at capturing fine par-
ticles. Higher CADR rates indicate im-
proved performance in all room sizes.
Note: The PCO500 Air Purifier is sug-
gested for use in a single, closed room
up to 265 square feet. The PCO300 Air
Purifier is suggested for use in a single,
closed room up to 175 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.
