Introduction:air purifierIt is a small household appliance product used to purify indoor air, mainly solving indoor air pollution problems caused by decoration or other reasons. Due to the persistent and uncertain release of pollutants in indoor air, using air purifiers to purify indoor air is the most effective method to improve indoor air quality.
　　
There are various technologies and media in air purifiers that enable them to provide users with clean and safe air.

The commonly used air purification technologies include: low-temperature asymmetric plasma air purification technology, adsorption technology, negative ion technology, negative oxygen ion technology, molecular complexation technology, TiO2 technology, HEPA filtration technology, electrostatic dust collection technology, reactive oxygen species technology, etc; The material technology mainly includes photocatalysts, activated carbon, synthetic fibers, HEAP materials, etc.
　　
At present, the existing air purifiers in the domestic market mostly adopt composite types, which simultaneously use multiple purification technologies and material media.
　　
Air purifier (also known as "air cleaner" or air freshener) refers to a product that can adsorb, decompose, or convert various air pollutants (generally including decoration pollution such as dust, pollen, odors, formaldehyde, bacteria, allergens, etc.), effectively improving air cleanliness. Currently, household and commercial air purifiers are mainly used to remove indoor air pollution.
　　
Composition of air purifier
　　
The main components of an air purifier include: chassis shell, filter section, air duct design, motor, power supply, LCD display screen, etc. The motor determines the lifespan, the filtration section determines the purification efficiency, and the air duct design, chassis shell, filtration section, and motor determine whether it is quiet or not.

Shanghai Anjule Biotechnology Co., Ltd., the air purifier supplier for the 2008 Beijing Olympics and 2010 Shanghai World Expo, pointed out that the important part of air purifiers is the technical core, which refers to the principle and method used for purification.
