More methods for indoor air purification in 2021 and 2022

The penetration rate of air purifiers is very high in European and American countries. We even know that the countries where these air purifiers belong are blue sky countries, and there is no problem of smog at all. Why do they still have so many people using air purifiers?

Does anyone really know what indoor air pollutants are? But we know all kinds of pollutants in the air have more or less impact on human health, so what methods can be used to remove these pollution? Now we will introduce more methods for indoor air purification.

1. Adsorption method

The adsorption method uses porous solids as adsorbents to attach certain components to the solid surface to achieve air purification, including physical adsorption and chemical adsorption. The most representative adsorption method is activated carbon, which is the most effective air purification method. Others include diatom mud, navika, methanol spray, and so on.

But the biggest problem with adsorbents is that they are saturated with adsorption and need to be desorbed, otherwise the adsorption effect will be lost. In other words, the trash can is full, bacteria will grow if it is not disposed of, and it will not be possible to continue loading.

2. Photocatalytic oxidation technology

This is a technology that uses photochemistry and catalysts to act together to cause and catalytic oxidation reactions to purify the air. The name is more difficult to understand, but when it comes to photocatalyst, I believe many people have heard of it.

Photocatalyst is a kind of catalyst. Under the action of ultraviolet light, it can effectively degrade toxic and harmful gases in the air and kill a variety of bacteria. It also has the functions of removing formaldehyde, deodorizing, anti-pollution, and purifying the air. The purification principle is not good, but it is limited to the surface with photocatalyst, so the actual effect is not ideal.

3.ozone method

Ozone has strong oxidizing properties and has obvious effects on sterilization and deodorization. Using ozone to purify air is an efficient method. However, ozone is toxic and cannot be used in an environment where organisms exist.

4. Electrostatic dust removal technology

This is an efficient air purification technology that can remove organic compounds and bacteria attached to dust particles while removing dust. However, this technology is easy to produce ozone, and more particles adsorbed on the dust collecting plate will affect the effect, and the dust collecting plate needs to be cleaned or replaced regularly.

5. negative ion method

The negative ions in the air have the effect of adsorption and condensation on the substances in the air, turning them into large ions and sedimenting, so as to achieve the purpose of air purification. Because the stability of negative ions is very poor, the actual purification effect is not obvious, but negative ions have a good impact on human health, so they are often widely used.
