1. filter adsorption type
The use of porous filter materials, such as non-woven fabrics, filter paper, fibers, foam cotton, etc., adsorbs suspended particles in the air, harmful gases, thereby purifying the air.
2. electrostatic dust collection
The pollutants in the air are charged by static electricity, and then the air dust adsorbing the charged particles is collected by the dust collecting device to purify the air.
3. composite type
At the same time, the air is cleaned by filtration and electrostatic dust removal.
