Air purifiers are usually equipped with multiple layers of filters inside, which filter out particles of different sizes through different layers of filters. At the same time, the use of adsorbents to adsorb harmful gases, electrochemical principles to decompose harmful substances, ultraviolet sterilization, and other methods can comprehensively improve the air purification effect. Different filters of household air purifiers have different filtering effects on different types of pollutants. For example, HEPA filters have better filtering effects on particulate matter, while activated carbon filters have better adsorption effects on harmful gases.

Home air purifiers can remove decoration odors, board odors, etc., ensuring that people live in a fresh and odorless environment. Removing particles such as fly ash, dust, pollen, etc. is particularly important for people who are sensitive to the nasal cavity. By using technologies such as negative ions or UV lamps, indoor microbial contamination such as bacteria and viruses can be effectively removed. By using activated carbon filters or more advanced ASNC nano mineral adsorption systems, combined with formaldehyde decomposition systems, indoor formaldehyde can be effectively removed.

A household air purifier is a product used to remove indoor air pollutants. It mainly uses various technologies such as filtration, adsorption, electrochemistry, and ultraviolet radiation to remove pollutants in the air, including PM2.5, formaldehyde, benzene, bacteria, viruses, allergens, etc., in order to provide users with a healthier indoor environment. Haze, secondhand smoke, pet dander, dust mites, pollen, and harmful gases produced by indoor decoration all invisibly threaten our respiratory health. In order to create a fresher and healthier living environment, household air purifiers have emerged and become an indispensable household appliance for many families.

Physical air purifiers use high-efficiency filtering materials such as HEPA filters, which can effectively remove large and small particles such as dust, pollen, and bacteria from the air. The physical filtration method is mature and stable, and is not prone to secondary pollution. But the filter needs to be cleaned or replaced regularly, which increases the cost of use. Some products may produce significant noise during high-speed operation.

The air purifier is equipped with multiple layers of filters, including primary filters, HEPA filters (high-efficiency air filters), activated carbon filters, etc., which can effectively intercept large and small particles, harmful gases, and odors in the air. Some high-end air purifiers are also equipped with ultraviolet sterilization lamps or photocatalyst technology, which can kill bacteria, viruses and other microorganisms in the air, further ensuring the safety of indoor air.
