1. When kn95 receives contamination such as saliva, blood, tears and other bodily fluids, it should be replaced
2. The user obviously feels that the respiratory resistance is greater than before and must be replaced
3. The masks are damaged and must be replaced
4. It is recommended to replace it after using it 4 times.
However, the masks cannot be reused if people go to the hospital, come into contact with an infected person or are suspected of being infected.
