? ? ? Air purifiers, also known as “air cleaners”, air purifiers, purifiers, are capable of adsorbing, decomposing or converting various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.). , bacteria, allergens, etc., products that effectively improve air cleanliness, mainly divided into household, commercial, industrial, and building.
? ? ?There are many different technologies and media in the air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalytic technology, superstructure photomineralization technology, HEPA high efficiency filtration technology, electrostatic dust collection technology, etc.; material technology mainly includes: photocatalyst, activated carbon, Synthetic fiber, HEPA high-efficiency material, negative ion generator, etc. The existing air purifiers are mostly compounded, that is, a plurality of purification technologies and material media are simultaneously used.
