- FFP2/N95 mask can isolate smaller particles and fit tighter to the face, it is not easy to leak air from the periphery and the filtration efficiency of particulate matter can reach 95% under standard conditions. - The FFP2/N95 mask is not a disposable mask. In this special case (resource shortage), it can be reused. But there are conditions:
When FFP2/N95 receives contamination such as saliva, blood, tears and other body fluids, it must be replaced
The user obviously feels that the breathing resistance is greater than before and must be replaced
Masks are damaged and must be replaced
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.
