  As we all know, the air pollution in this city is particularly serious, a lot of people are wearing masks, to prevent smog when a mask on the market now more and more, but, anti-smog masks are more popular among users, here is to introduce what users should pay attention to when choosing a disposable medical mask.

  When buying an anti-haze mask, one is to check whether the anti-haze mask is suitable for the face, whether there is a lot of air leakage around the nose and chin, and whether the mask is poor in sealing, so don't wear it. Here we tend to set the mask on the head rather than hanging it on the ear of the mask.

  Check to see if you're breathing well, that is, if you can keep your breathing normal. If breathing is not smooth, there will be a lot of water vapor, students wearing glasses have such experience, glasses will be covered by a layer of fog. Therefore, we recommend that you choose a mask with a breathing valve.

  Because the outer layer of the mask often accumulates a lot of dirt, bacteria and other dirt in the outside air, while the inner layer blocks the exhaled bacteria and saliva, the two sides cannot use it alternately. Otherwise, the dirt infected by the outer layer will be inhaled directly to the face and become the source of infection.
