Air purification sterilizer Difference from air purifier!
First of all, we should understand the difference between medical air disinfection purifier and air purifier, and what are their uses.
Medical air disinfection purifier: it has disinfection and sterilization effect, and the number of sterilization falls meets the requirements of the National Health Commission. Hospital operating rooms and public supply places are the main use places. At present, the air disinfection purifiers commonly used in the market have electrostatic field skills, which are relatively common.
Air purifier: It has the effect of air purification and filtration, and can effectively block the dust, hair and particles (PM2.5) in the air. At present, the air purifiers on the market are mainly blocked by HP high-efficiency filter cotton and activated carbon, which have a certain effect on air purification and enable the air in the home environment to breathe freely.
It is difficult to remove the virus, because its size is very small, only 0.1 μ m. It is one thousandth of bacteria. Virus is a non cellular life form, and many methods of removing bacteria have no effect on virus.
The traditional filter type air purifier is a composite filter screen composed of HEPA filter screen+multiple structures to filter, absorb and purify air. The subtle presence of virus is difficult to filter, and further disinfection equipment is required.
At present, there are two ways for air purifiers to kill viruses on the market. One is ozone. The higher the ozone content, the better the virus removal effect. However, ozone overexpenditure will also cause damage to the human respiratory system, nervous system, immune system and skin. If you are exposed to excessive ozone for a long time, there is a potential risk of cancer. Therefore, people cannot be present in the air purifier disinfection method.
The other is that the ultraviolet ray with the wavelength of 200-290nm can penetrate the outer shell of the virus, causing damage to the internal DNA or RNA, making it lose the ability to reproduce, so as to achieve the effect of killing the virus. The air purifier can embed ultraviolet ray in the machine to avoid ultraviolet ray leakage, and people can be present at work.
