Air purifiers, also known as “air cleaners”, air purifiers and purifiers, refer to household appliances that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.) to effectively improve air cleanliness, mainly including household, commercial, industrial and building products.
There are many different technologies and media in the air purifier, so that it can provide users with clean and safe air. Common air purification technologies include adsorption technology, negative (positive) ion technology, catalysis technology, photocatalyst technology, super structure light mineralization technology, HEPA high efficiency filtration technology, electrostatic dust collection technology, etc; Material technology mainly includes photocatalyst, activated carbon, polar carbon core filter element technology, synthetic fiber, HEAP efficient material, negative ion generator, etc. Most of the existing air purifiers are of composite type, that is, a variety of purification technologies and materials are used at the same time.
