Is air purifier necessary?

Air purifiers have a variety of technologies and substances, which can provide consumers with clean and safe gas. Common air purification technologies include: adsorption technology, negative (positive) positive ion technology, catalysis technology, nano photocatalyst, super structure photoacidification technology, HEPA high efficiency filtration technology, electrostatic precipitator technology, etc. Activated carbon. Artificial fiber. HEPA high efficiency raw material A plasma generator, etc. Most of the existing air purifiers are made of composite materials, that is, a variety of technical materials and substances for purification treatment are selected.

In recent years, the air purifier market has developed rapidly. Despite the rapid development of the air purifier market, the coverage rate of the air purifier in the United States is 27%, and that in Japan is 17%. There is still a very large development prospect in the sales market of air purifiers in China. On the other hand, China has made every effort to popularize the professional knowledge of indoor air, improve the ecological environment control, and issued a series of countermeasures to make the energy-saving and environmental protection industry develop rapidly and the whole industrial chain of indoor air pollution (indoor air pollution) develop rapidly. Pollution monitoring, solution, air purifier, household fresh air system, etc.).
