Who knows that 3m masks can be washed ?
No, the 3M mask is maintenance-free, ie the mask cannot be cleaned. Professional anti-particle masks are not washable and sterilizable, otherwise the filter material in the mask and the structure of the mask will be damaged.

To be discarded, no longer use. Haze is harmful to the cardiovascular system of the human respiratory system. The 3m masks are made of high-static filter material, which filters the particles in the air and pm2.5. It can't be washed, otherwise it will destroy the filtering ability of the material. At the same time, when the mask is used for a period of time, the filtration efficiency will be reduced to none. Generally, the dust mask should be discarded in the following cases:
1. The particles absorbed by the mask are too high, and the user obviously feels that the breathing is blocked;
2. Damage, aging, damage or failure of the parts (such as broken headband, looseness, broken nose, falling off, damaged or deformed mask body);
3. The mask is contaminated, such as liquid splashes.
