The role of air purifier

The function of the air purifier is to remove particulate matter in the air, including allergens, indoor PM2.5, etc., and it can also solve the problem of indoor, underground space, and car volatile organic compounds air pollution caused by decoration or other reasons. Because the release of air pollutants in a relatively closed space has the characteristics of 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 purifiers are also called "air cleaners", air fresheners, and purifiers. They are capable of adsorbing, decomposing or transforming various air pollutants (generally including PM2.5, dust, pollen, peculiar smell, formaldehyde, etc.) Decoration pollution, bacteria, allergens, etc.), products that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building.

    There are many different technologies and media in the air purifier, which enable it to provide users with clean and safe air. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, Synthetic fiber, HEPA high-efficiency material, negative ion generator, etc. Most of the existing air purifiers are of composite type, that is, multiple purification technologies and material media are used at the same time.
