The function of air purifier is to remove particulate matter in the air, including allergens, indoor PM2.5, etc. At the same time, it can also solve the indoor, underground space and car volatile organic matter air pollution caused by decoration or other reasons. Since the release of air pollutants in a relatively enclosed space is characterized by persistence and uncertainty, the use of air purifiers to purify indoor air is one of the internationally recognized methods to improve indoor air quality.

Air purifier is also known as "air cleaner", air freshener, purifier, refers to the adsorption, decomposition or transformation of various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.), effectively improve air cleanliness products, mainly divided into household, commercial, industrial, building.

The HEPA screen of air purifier on the market is commonly used in several grades H11, H12 and H13. Common configurations are H12 and H13 filters, both of which can meet the need for particulate matter purification.
