Air purifier particulate matter purification technology

The particle purification technology of air purifiers can mainly be classified into three categories: physical filtration, electrostatic collection, and active ion purification. Currently, most products on the market are composite purifiers that integrate multiple technologies.

Adsorption utilizes the large specific surface area and porous structure of materials to capture particulate pollutants. It is prone to clogging and is more effective for removing gas pollutants. The materials used are generally activated carbon.

Filtering mainly involves direct interception. Usually, it uses HAPE filters, which have good collection effects on fine particles but have high wind resistance. To achieve high purification efficiency, the filter needs to be replaced regularly after saturation. At the same time, the accumulated particles on the HAPE filter are prone to breeding microorganisms, which can easily cause secondary pollution. The purification efficiency is high and stable, with clear quantitative standards (such as 99.97%), and no secondary pollutants such as ozone are produced.
