What should I search for in an air cleanser?

CADR (clean-air delivery rate) ranking. This determines the cleansing 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 model designed to operate in the space size. Choose a design that is designed for an area larger than the one you are outfitting it for if you wish to run it at a lower, quieter setting.

Remember, it is very important to note that in reality settings, the actual efficacy of these gadgets would be far less as new toxins are continuously emerging.
