Research Progress of Air Purifier Principles and Material Technologies

摘要

This article mainly refers to purification technology and material technology of air purifiers. There are several purification technologies in air purifiers such as HEPA(high efficiency particulate air filter), Mineralization technology of ultra light structure, Negative ion technology, the photocatalyst technology, electrostatic dust collection, Activated carbon adsorption technology and etc. And material technologies are classified as Photocatalyst, Activated carbon, Synthetic fiber, HEP A, Negative ion generator and etc. The paper reviews the characteristics, purification theory, research status and applications of every kind of purification technologies and material technologies. On this basis, we put forward outlook on the future development of air purifier.
