The kn95 mask is not a disposable mask. In this special case (resource shortage), it can be reused. But there are conditions:
1. When kn95 receives contamination such as saliva, blood, tears and other body fluids, it must be replaced
2. The user obviously feels that the breathing resistance is greater than before and must be replaced
3. Masks are damaged and must be replaced
4. It is recommended to replace it after using it 4 times.
However, masks cannot be reused if people go to the hospital, come into contact with an infected person, or are suspected to be infected.
