What should I search for in an air cleanser?

CADR (clean-air shipment rate) ranking. This determines the cleaning speed of the cleanser for getting rid of smoke, dust, and and pollen. Look for a CADR of a minimum of 300, above 350 is really fantastic.

For proper efficacy, you need a design developed to operate in the room size. Select a design that is developed for a location larger than the one you are outfitting it for if you want to run it at a lower, quieter setting.
