What kinds of air purifiers are there?

Common types of air purifiers include the following:

Mechanical filter: Mechanical filter uses screen and electrostatic effect to filter. Fine particles such as dust, pollen and dust in the air can be filtered out through the filter screen. Through electrostatic action, bacteria, viruses and other microorganisms in the air can be adsorbed. This air purifier is suitable for small spaces such as homes and offices.

Activated carbon filter: Activated carbon filter purifies the air through adsorption. Activated carbon has a very large surface area, which can absorb harmful gases such as odor, formaldehyde and benzene in the air. This air purifier is suitable for special scenes such as oil smoke and kitchen odor.

Ultraviolet sterilization air purifier: ultraviolet sterilization air purifier kills bacteria, viruses and other microorganisms in the air through ultraviolet irradiation. This air purifier is suitable for hospitals, laboratories and other environments.

Negative ion air purifier: The negative ion air purifier uses a negative ion generator to increase the concentration of negative ions in the air by releasing negative ions, thus improving air quality.
