What should I try to find in an air cleanser?

CADR (clean-air delivery rate) score. This measures the cleaning speed of the purifier for getting rid of smoke, dust, and and pollen. Search for a CADR of a minimum of 300, above 350 is actually terrific.

For correct efficacy, you need a design designed to work in the room size. Pick a model that is created for a location larger than the one you are outfitting it for if you want to run it at a lower, quieter setting.
