Information

In the special period when respiratory safety is concerned, we are paying more and more attention to air purifiers, especially the air purifier for viruses that can remove viruses. What kind of air purifier for viruses is really effective for virus removal?

air purifier for viruses

The reason why it is difficult to remove the virus is because its size is extremely small, only 0.1μm in size, which is one thousandth of the size of bacteria. Moreover, viruses are a non-cellular life form, and many methods to remove bacteria are actually completely ineffective for viruses.

The air purifier for viruses on the market mainly includes ozone disinfection, ultraviolet disinfection, electrostatic dust collection, and high-efficiency filter materials. However, different technologies use different principles and have different effects on virus removal.

The ozone's response to virus inactivation is very rapid. It can oxidize all parts of the virus: directly destroy the protein coat of the virus, and further damage the virus's DNA or RNA. At the same time, ozone will also interfere with the adsorption of the virus to the depository, and completely remove the virus. The higher the ozone content, the more thorough the virus removal effect will be. However, excessive ozone can also cause damage to the human respiratory system, nervous system, immune system, and skin. If you stay in an environment with too much ozone for a long time, there are potential carcinogenic risks and so on.

Add a common UV ultraviolet lamp inside the air purifier for viruses. The ultraviolet light with a wavelength of 200-290nm can penetrate the outer shell of the virus, cause damage to the internal DNA or RNA, and make it lose the ability to reproduce, so as to achieve the effect of killing the virus. . In actual use, the duration of ultraviolet radiation and the distance of the light source have a great influence on the actual antivirus effect. Most of the air purifier for viruses with ultraviolet disinfection function, the nominal virus removal rate may be due to the internal high-efficiency filter element.

Static electricity can adsorb the passing virus on the filter and kill the virus by releasing high voltage. But in fact, there is no reliable evidence to support this principle, and the virus removal rate of air purifier for viruses equipped with this kind of technology may still be the effect of the filter.

High-efficiency filter materials can not only filter PM2.5, pollen, bacteria, etc., but also have a clear removal effect on virus carriers, and the filtering method does not produce harmful "by-products" such as ozone and ultraviolet rays, and is safe. According to different filtering effects, the air purifier for viruses filter material also has a strict classification, and different countries have different classification basis for this classification.
