WHAT IS CADR AND WHY IS IT IMPORTANT?
The Clean Air Delivery Rate (CADR) is a measure of the reduction rate (cleaning
speed) of specific particulates by an air purifier or other filtration system in a
controlled environment. A higher CADR means that the air purifier cleans the air
more quickly than a unit with lower CADR. CADR is the one performance measure
and the air volume processed by the air purifier. CADR is usually measured for
three particle types: smoke, dust, and pollen. According to the Asso ciation of Home
Appliance Manufacturers (AHAM) Room Air Cleaner Certification Program, the
recommended room size is directly related to the smoke CADR.
Look for the AHAM mark on the front of the package and the CADR rating label on
the back of the package. The CADR rating label will list the CADR rating for tobacco
smoke, dust, and pollen, and it will also list the recommended room size per the
AHAM certification.
