(2) If used repeatedly, the outer layer of the protective mask often accumulates a lot of dirt, bacteria, viruses and other contaminants in the outside air.

2. Disinfection. Soak the cleaned face protective mask in a 2% peroxyacetic acid solution for 30 minutes or cook in boiling water for 20 minutes or steam in a steamer for 15 minutes, and then air dry for later use. This method is suitable for gauze masks and bowl masks.
3. Check. Before using it again, you should carefully check whether the protective masks are still intact. For gauze masks and masks, you can use the light transmission inspection method, that is, take care of them before the lamp to see if there are obvious light spots, and the middle and edge parts are transparent Is the rate consistent? If in doubt, replace it with a new one. Regardless, protective masks are generally updated after 3 to 7 times of washing, and masks of particularly good quality can be washed 10 times.
