With the official release of PM2.5, the word PM2.5 has been a hot topic, so all kinds of protective equipment began to sell, especially masks, but what kind of anti-fog mask is good? Which kind of mask can really Filter and purify PM2.5. At present, there are many kinds of anti-PM2.5 masks and anti-influenza virus masks on the market, which are complicated and complicated, and many fish eyes are mixed.
Generally, what kind of anti-fog mask is good? The subdivision category and protection level can be judged from the following categories.
1. Chemical fiber masks: The main components of chemical fiber mask materials are chemical fiber materials. The mask itself does not contain filter material for protection and blocking. Therefore, the barrier effect on dust is quite limited, let alone PM2.5 or influenza virus. But wearing one is better than not wearing it.
Second, disposable mask: The main material of disposable mask is non-woven fabric plus a layer of filter cloth, which has a small effect on dust and some PM2.5 and avian influenza virus, but for fine particles such as PM2.5 and The blocking effect of avian influenza and other pathogens is also limited.
Third, cotton mask + ordinary filter mask: Now the market hot fried PM2.5 mask is more than this one, a layer of cotton plus a common non-woven filter on the mouth said that the mask can block the filter PM2.5 micro Granules, in fact, as long as we get the product and then think about it, we will understand that the mask's role in blocking PM2.5 and bird flu virus is not particularly large. Of course, it is excellent in terms of practicality and visual beauty. In the first two.
Fourth, industrial protective mask (N95 type): The main material of N95 mask is imitation cotton cloth plus special filter cotton for mask, plus the mask design of the overall design of the mask is relatively good for the blocking and filtering effect of PM2.5 and bird flu virus. N95 masks also have good protective effects in the environment of industrial dust and toxic gases, and the historical time of use is relatively long, so the recognition of this is relatively high.
5. Nano antibacterial material + activated carbon + microfiber filter (nano anti-virus PM2.5 special mask): This mask is made of relatively mature nano material (nano silver) attached to the mask fabric. Everyone knows that nano silver can be It is used for disinfection and purification of drinking water, so it also has a strong decomposition and killing effect on micro-polluting particles such as PM2.5 and bacterial germs adsorbed on the mask. Conditionally, you can use an air purifier, use the Chuangpu Net USB Mini Purifier and open the window less in foggy weather.
The above is a good introduction to the anti-fog mask, I hope to be helpful to everyone. At the same time, I hope that you pay attention to the distinction when purchasing
