    Masks should be cleaned and disinfected daily. Both gauze masks and air filter masks can be disinfected by heating. The specific approach is:

    1. Cleaning. Gently rub the gauze mask with warm water and soap. The bowl-shaped mask can be gently cleaned with a soft brush dipped in detergent, and then washed with water. Please be careful not to rub hard, because if the warp and weft gap of the gauze is too large, it will lose the effect of preventing droplets.

    2. Disinfection. Soak the cleaned face mask in a 2% peroxyacetic acid solution for 30 minutes or cook in boiling water for 20 minutes or put it in a steamer for 15 minutes, then dry it for use. This method is suitable for gauze masks and bowl masks.

    3. Check. Before using it again, you should carefully check whether the masks and masks are still intact. For the gauze masks and masks, you can use the light transmission inspection method. Is the rate consistent? If in doubt, replace it with a new one. In any case, masks and masks are generally updated after 3 to 7 times of cleaning, and masks of particularly good quality can be washed 10 times. Activated carbon adsorption masks should be replaced regularly with activated carbon interlayers. If activated carbon interlayers are not replaceable, they must be replaced after 7 to 14 days. This type of mask cannot be reused after cleaning.


    The outer layer of the mask often accumulates a lot of dirt, bacteria and other dirt in the outside air, and the inner layer blocks exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the dirt contaminated by the outer layer will directly adhere to When inhaled on the face, it becomes a source of infection. When not wearing the mask, it should be folded into a clean envelope, and the side that is close to the nose and mouth should be folded inward. Do not put it in your pocket or hang it around your neck.

    If the mask is wet with exhaled heat or saliva, its barrier effect will be greatly reduced. Therefore, it is best to prepare a few more masks in order to replace them, and they should be changed and washed once a day. When washing, first blanch with boiling water for 5 minutes.
