Clean Air Delivery Rate (CADR)
Most air purifiers are certified by the Association of Home Appliance Manufacturers (AHAM) with
Clean Air Delivery Rate (CADR). If a unit is not AHAM certified, this should raise a warning signal about
the unit.
CADR measures the performance of an air purifier and is an important feature consumers can use
worldwide to compare different brands of air purifiers. The CADR is a rating determined by AHAM that
reflects how fast a unit removes airborne pollutants such as dust, pollen and tobacco smoke from a
room by indicating how much 100% clean air is delivered. The higher the CADR, the faster is the unit
able to filter the air in a particular room.
For example, if an air cleaner has a CADR of 375 cfm for tobacco smoke particles (as the Blueair 503
does), it will reduce smoke particle levels to the same concentration as would be achieved by adding
375 cu. ft. of 100% clean air every minute. Each model’s performance has been independently veri-
fied through testing at a third party laboratory.

ENERGY STAR
®
ENERGY STAR is a program that certifies products for low energy consumption and running cost.
When ENERGY STAR measures the energy efficiency of an air purifier, not only wattage is taken into
account but also the performance in comparison to the energy consumption.
Blueair was among the first air purifier brand to get ENERGY STAR designation for all units. Blueair air
purifiers significantly exceed minimum standards and with the ECO10, Blueair has the most energy
efficient air purifier in the world.
