What should I try to find in an air purifier?

CADR (clean-air shipment rate) rating. This measures the cleansing speed of the purifier for getting rid of smoke, dust, and and pollen. Look for a CADR of at least 300, above 350 is actually terrific.

For proper effectiveness, you require a model developed to work in the space size. Select a design that is created for an area larger than the one you are outfitting it for if you want to operate it at a lower, quieter setting.

The market requirement for such is that the system needs to be able to get rid of at least 99.97% of particulates measuring 0.3 micron diameter in a laboratory setting. Keep in mind, it is very important to note that in reality settings, the real efficacy of these gadgets would be far less as new pollutants are constantly emerging.
