Common types of air purifiers include the following:
Mechanical filters: mechanical filters use screens and electrostatic effects for filtration. Through the filter, it is able to filter out fine particles such as dust, pollen and dust in the air. And through the electrostatic effect, it can adsorb bacteria, viruses and other microorganisms in the air. This kind of air purifier is suitable for small spaces such as homes and offices.
Activated carbon filter: activated carbon filter uses adsorption to purify the air. Activated carbon has a very large surface area and can adsorb odors, formaldehyde, benzene and other harmful gases in the air. This kind of air purifier is suitable for special scenarios such as smoke, kitchen odor and so on.
Ultraviolet germicidal air purifier: ultraviolet germicidal air purifier can kill airborne bacteria, viruses and other microorganisms through ultraviolet irradiation. This kind of air purifier is suitable for hospitals, laboratories and other environments.
Negative ion air purifier: Negative ion air purifier adopts negative ion generator, through the release of negative ions, to increase the concentration of negative ions in the air, so as to improve air quality.
