Cleaning And Maintenance Of Masks

The outer layer of the mask often accumulates a lot of dust, bacteria and other dirt in the outside air, while the inner layer blocks the exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the dirt on the outer layer will be directly attached to it. It becomes a source of infection when it is inhaled into the human body when it is in the face. When you are not wearing the mask, you should fold it and put it in a clean envelope, and fold the side close to your nose and mouth. Don't just stuff it in your pocket or hang it around your neck.

If the mask is wetted by exhaled heat or saliva, its function of blocking germs will be greatly reduced. Therefore, it is best to prepare a few more masks so that they can be replaced. They should be changed and washed once a day. When washing, it should be scalded with boiling water for 5 minutes.
