Air purifiers are used in home, medical, and industrial fields. Home-based home air purifiers are the mainstream products in the market. The most important function is to remove particulate matter in the air, including allergens, indoor PM2.5, etc., and also solve the air pollution problem of indoor and underground space and volatile organic compounds in the car due to decoration or other reasons. The use of air purifiers to purify indoor air is an internationally recognized method for improving indoor air quality due to the persistence and uncertainty of the release of air pollutants in relatively closed spaces.
