Traditional air purification equipment adopts different filtration systems, and the types of air pollution removed are also different.
There are three main types, one is filter type air purification equipment, usually with activated carbon as a filter material.
Through activated carbon filter out benzene, formaldehyde and other harmful substances in the air, to achieve the purpose of purifying indoor air.
The second is the electrostatic air purification equipment, which concentrates the dust in the air in the dust collecting board by adsorption, and kills bacteria and viruses by the strong electric field on the dust collecting board, so as to achieve the purpose of purifying the air. However, the adsorption effect of this air purification equipment on harmful substances such as formaldehyde and benzene is worse than that of filter air purification equipment.

The third is the photocatalytic air purification equipment, which can be converted into harmless water and carbon dioxide through a series of chemical reactions after adsorption of various harmful substances. But it only works when exposed to sunlight or ultraviolet light, and the effect on bacteria is limited

Ozone disinfection function absorbs, decomposes and transforms various pollutants in the air, including dust, pollen, odor, bacteria, second-hand smoke, etc., and can also purify pollutants caused by decoration formaldehyde, benzene, bacteria, allergens, etc., to improve air cleanliness.
Ozone disinfection machine purification air efficiency is high, ozone distribution in the air, as long as the ozone concentration in the air reaches a certain value, it can effectively kill bacterial viruses. The raw material of ozone preparation is oxygen in the air, ozone has an unstable effect, at normal temperature and pressure, can be automatically decomposed into oxygen, no secondary pollution concerns.

In the choice of functions, it depends on the environment and the needs of different people.
In areas where the humidity is moderate, or where the air quality requirements are not too high, pure purification air purification equipment can be purchased;
Dry areas, or often open air conditioning indoor air dry families, should buy air purification equipment with humidification and purification function;
In areas or seasons with high air humidity, such as Shenzhen in the rainy season in March and April, air purification equipment with dehumidification and purification function should be selected.
The indoor area is small, or people who are in a large number of people and indoor pollution for a long time can choose a small desktop air purification equipment.
Motorists should choose vehicle air purification equipment. Families with infants should choose air purification equipment with multiple filtration systems.
Families with better economic conditions can choose an intelligent air purification equipment
