Wearing a new mask is an effective way to block the transmission of respiratory secretions. At present, the masks that can be seen on the market mainly include medical protective masks (such as N95 masks), medical surgical masks and general disposable medical masks. In addition, there are cotton masks and sponge masks on the market. We choose surgical masks for daily protection. N95 mask has better disease prevention effect, but it is not suitable for wearing for a long time due to its poor air permeability and high respiratory resistance.

2. How to wear the mask correctly?

When wearing the mask, fully unfold the folded face, completely wrap the mouth, nose and mandible, and then compress the nose clip to make the mask fully fit the face.

Wash your hands before wearing the mask, or avoid touching the inner face of the mask during wearing, so as to reduce the possibility of contamination of the mask. To distinguish the inside and outside, up and down of the mask, the light color should be the inside, the inside should be close to the mouth and nose, the dark side should face out; one end of the metal strip (nose clip) is the top of the mask. The mask should be replaced regularly. It is not allowed to wear it on the inside and outside, not to mention on both sides in turn.
