air cleaner

Air purifier, also known as "air cleaner", air freshener and purifier, refers to the products that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, peculiar smell, formaldehyde and other decoration pollution, bacteria, allergens, etc.) and effectively improve air cleanliness, mainly divided into household, commercial, industrial and building.

空气净化器中有多种不同的技术和介质，使它能够向用户提供清洁和安全的空气。常用的空气净化技术有：吸附技术、负（正）离子技术、催化技术、光触媒技术、超结构光矿化技术、HEPA高效过滤技术、静电集尘技术等；材料技术主要有：光触媒、活性炭、合成纤维、HEPA高效材料、负离子发生器等。现有的空气净化器多采为复合型，即同时采用了多种净化技术和材料介质。

There are many different technologies and media in the air purifier, which can provide clean and safe air for users. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalysis technology, photocatalyst technology, super structure photochemical mineralization technology, HEPA high efficiency filtration technology, electrostatic dust collection technology, etc.; material technology mainly includes: photocatalyst, active carbon, synthetic fiber, HEPA high efficiency material, negative ion generator, etc. Most of the existing air purifiers are of composite type, that is, a variety of purification technologies and material media are used at the same time.
