The clue to what they do is in the name — air purifiers help clear the indoor air of dust, harmful chemicals, allergens and many other airborne pollutants. Some appliances even come with built-in humidifiers or germ-killing features. But do air purifiers help with bad smells, too?
The answer to this question is not straightforward. Certain air purifiers can remove some of the particles that may cause bad smells. However, no air cleaner or filter will be able to eliminate all the particles that can cause strong odors, according to the United States Environmental Protection Agency (EPA).
