Air purifiers are products that can adsorb, decompose or transform various air pollutants (generally including decoration pollution such as PM2.5, dust, pollen, peculiar smell, formaldehyde, bacteria, allergens, etc.) and effectively improve air cleanliness. They are mainly divided into household, commercial, industrial and building products.

There are many different technologies and media in the air purifier, which enable it to provide clean and safe air to users. Common air purification technologies include: adsorption technology, negative (positive) ion technology, catalysis technology, photocatalyst technology, super structured light mineralization technology, HEPA efficient filtration technology, electrostatic dust collection technology, etc; Material technology mainly includes photocatalyst, activated carbon, synthetic fiber, HEPA high efficiency material, anion generator, etc. The existing air purifiers are mostly of composite type, that is, a variety of purification technologies and material media are adopted at the same time.

The air purifier can filter dust, smoke and bacteria smaller than cells to prevent lung disease, lung cancer, liver cancer and other diseases. The most harmful to human body in the air is the dust less than 2.5 microns, because it can penetrate cells and enter the blood. Ordinary purifiers use filter paper to filter the dust in the air, which is very easy to block the filter hole. The dust not only has no sterilization effect, but also is easy to cause secondary pollution.
