A kind of propaganda head that may exist in air purifier for dust removal is electrostatic dust removal. Speaking of electrostatic dust removal, many people may not be unfamiliar, because it is true that such sensitive words can often be captured in the advertising words of some air purifier for dust removal, and this is based on the knowledge and experience of most people. We can understand the dust removal method, but whether it is actually so effective, we still need to analyze and judge seriously, and we must not say anything.

The principle of electrostatic dust removal of air purifier for dust removal is not as simple as ordinary people understand, but a kind of gas ionization or corona phenomenon. Because the tiny particles in the air are often exposed to radiation from different directions or self-friction during their movement, they will carry a small amount of free ions. In this case, although the overall gas mass itself does not exhibit electric power. , But if an electrostatic field with a certain voltage is applied to such a gas, the free ions in the air will move to the poles and in the process of moving, they also form internal currents, and with the strength of the electric field The higher the movement, the faster the movement, and the naturally formed current will be more intense. Finally, when the voltage rises to a certain fixed value, the ions near the electrode gain higher energy and speed, so that the charged ions It will impact the neutral atoms that are originally uncharged in the air, and the neutral atoms will also be decomposed into two kinds of positive and negative ions. Such a phenomenon in which the air finally decomposes into positive and negative ions is usually called the air ionization phenomenon.

Under normal circumstances, in order to effectively eliminate this corona phenomenon, materials with higher structural parameters and better quality are selected. We have no way of knowing whether some ordinary air purifier for dust removal use such materials, because it needs to be verified by the relevant appraisal agency to draw a conclusion, in addition to many air purifier for dust removal Manufacturers use ordinary filter paper to filter the dust in the air. This approach will harm human health to a certain extent, because if only filter paper is used to filter the dust in the air, it is very easy to block the filter holes, and if no one can replace the filter paper regularly, Then there will be more dust and bacteria accumulating, and letting it go will cause a second pollution, which will pose a great threat to human health.
