What should I try to find in an air cleanser?

CADR (clean-air shipment rate) score. This determines the cleaning speed of the cleanser for getting rid of smoke, dust, and and pollen. Try to find a CADR of at least 300, above 350 is truly terrific.

For appropriate effectiveness, you need a design developed to operate in the space size. Choose a model that is designed for a location larger than the one you are equipping it for if you wish to operate it at a lower, quieter setting.
