Mask is a kind of hygienic product, which is usually worn in the mouth and nose to filter the air entering the mouth and nose, in order to prevent harmful gases, odors, droplets from entering and leaving the wearer's mouth and nose. It is made of gauze or paper.
Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, when working in a polluted environment such as dust, wearing masks has a very good effect.
Reasons for respirator replacement:
1. Masks contaminated with foreign bodies such as bloodstains or droplets
2. Users feel greater respiratory resistance
3. Mask damage
4. Dust-proof filter cotton, under the condition that the mask is close to the user's face, when the user feels great respiratory resistance, it means that the filter cotton is covered with dust particles and should be replaced.
5. Anti-virus filter box, under the condition that the mask and user's door are well closed, when the user smells the odor of toxic substances, it should be replaced.
6. Ordinary masks need to be cleaned for about 2 hours. Before cleaning, they should be soaked in boiling water for 5 to 8 minutes. Activated carbon masks can be used for 2 days and N95 for one week. If the mask is not worn for a long time after cleaning, it is better to clean it again before wearing it.
