The respirator ffp3  should be cleaned and disinfected every day. Whether it is a gauze mask or an air filter mask, it can be disinfected by heating. The specific method is:

1. Wash. First, 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 clean water. Please be careful not to rub it 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 mask in 2% peracetic acid solution for 30 minutes or boil it in boiling water for 20 minutes or steam it in a steamer for 15 minutes, then dry it for later use. This method is suitable for gauze masks and bowl masks.

3. Check. Masks and face coverings should be carefully checked to see if they are still in good condition before being used again. In any case, the respirator ffp3 generally needs to be updated after 3 to 7 times of cleaning, and a particularly good quality mask can be cleaned 10 times.
