Can I wash the FFP2 Mask?Of cause not. Water vapor will also cause static discharge, which will cause the mask to fail. Then how can we clean the FFP2 Masks? 

The outer layer of FFP2 Masks tends to accumulate a lot of dust, bacteria and other dirt in the outside air, while the inner layer blocks the exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the dirt on the outer layer will be directly exposed. It becomes a source of infection by inhaling the body when it is close to the face. When you are not wearing the mask, you should fold it and put it in a clean envelope, and fold the side close to your nose and mouth. Don't just stuff it in your pocket or hang it around your neck.

FFP2 Masks are similar to N95 and KN95 masks and cannot be cleaned. Because it gets wet, the mask will release static electricity, and it will not be able to absorb dust with a diameter of less than 5um.

 

High-temperature steam disinfection is similar to water wash cleaning. If you have a UV lamp at home, you can consider using it to sterilize the surface of the mask to prevent accidental contact with the surface of the mask and cause pollution. High temperature can also be sterilized, but masks are usually made of flammable materials. High temperature may also cause Masks to burn and cause safety hazards. It is not recommended to use ovens and other facilities for high-temperature disinfection.
