There are many different technologies and mediums in the air purifier that enable it to provide clean and safe air to users. Commonly used air purification technology are: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, ultra-structured optical mineralization technology, HEPA high efficiency filtration technology, electrostatic dust collection technology, etc. materials technology mainly include: photocatalyst, activated carbon, carbon core filter technology, synthetic fiber, heap high efficiency materials, negative ion generator and so on. The existing air purifier is more complex, that is, the use of a variety of purification technology and material media.
