The outer layer of the air-purifying respirator 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 surfaces cannot be used interchangeably, otherwise the contaminants in the outer layer will be contaminated. Inhalation of the body directly close to the face, and become a source of infection. When the mask is not worn, it should be folded and placed in a clean envelope. It should be folded tightly against the side of the mouth and nose. It should not be stuffed in the pocket or hung on the neck.

If the air-purifying respirator is moistened with exhaled hot gas or saliva, its effect of blocking germs will be greatly reduced. Therefore, it is best to prepare more masks at ordinary times so that they can be used alternately. They should be changed once a day. Wash with hot water for 5 minutes.

Air-purifying respirators should be cleaned and disinfected daily. Both gauze masks and air filter masks can be disinfected with heat. The specific approach is:

1. Clean. Gently rub the gauze mask with warm water and soap. The bowl-shaped mask can be gently brushed with a soft brush, then rinsed with water. Please note that do not rub hard, because if the longitude and latitude of the gauze is too large, it will lose the role of anti-impedance droplets.

2. Disinfection. Soak the clean mask in a 2% solution of peracetic acid for 30 minutes or boil in boiling water for 20 minutes or steam in a steamer for 15 minutes, and then dry it for use. This method is suitable for gauze masks and bowl-shaped masks.

3. Check. Before using it again, you should carefully check whether the mask and mask are still intact. For the gauze masks and masks, you can use the light transmission inspection method, that is, take a look before the lights to see if there are obvious light spots, and the middle part and the edge part of the light The rate is not the same. If there is doubt, it will be replaced with new ones. In any case, masks and masks are generally refreshed after 3 to 7 washings, and masks of particularly good quality can be washed 10 times.
