There are four kinds of disposable masks, of which the disposable three-layer masks are made very tightly and finely. There are two layers of woven cloth and filter paper. The two-layer woven cloth is more comfortable and does not have any facial irritation. The filter paper is more effective in filtering some toxic gases or small molecule toxic gases such as particles to protect people's health.

Precautions for wearing disposable masks:

1. Do not reuse disposable masks. The wearing time of disposable mask is generally 6 ~ 8 hours, which needs to be replaced once.

2. 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 can not be used alternately. Otherwise, the dirt on the outer layer will be inhaled into the human body when it is directly close to the face, and become the source of infection.

3. When the mask is not worn, it should be folded into a clean envelope, and the side close to the mouth and nose should be folded inward. Do not put it into the pocket or hang it around the neck.

5. If it is in a hospital and other high-risk places, no matter how long it is used, once the mask is taken off, it should not be used again, so as to avoid contamination caused by touching the mask by hands.

6. When wearing or removing the mask, the hands may be exposed to bacteria attached to the mask surface. In order to reduce the chance of infection due to contact, special attention should be paid to the cleaning and disinfection of hands.
