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.
This air cleaner is suggested for use in a single, closed room up to 183 square feet.
Higher CADR rates provide improved performance in all room sizes. Portable air cleaners will be much
more effective in rooms when all the doors and windows are closed.
