What should I try to find in an air purifier?

CADR (clean-air delivery rate) rating. This measures the cleaning speed of the purifier for getting rid of smoke, dust, and and pollen. Try to find a CADR of at least 300, above 350 is actually excellent.

For proper effectiveness, you require a model designed to operate in the room size. Pick a model that is designed for a location larger than the one you are outfitting it for if you want to operate it at a lower, quieter setting.

Remember, it is essential to keep in mind that in real life settings, the actual effectiveness of these devices would be far less as brand-new toxins are continuously emerging.
