Precautions for wearing KN95 mask:
1. Wash your hands before wearing a mask, or avoid touching the inner side of the mask while wearing a mask to reduce the possibility of contamination of the mask.
2. Distinguish the inside, outside, top and bottom of the mask; the KN95 mask has the printed side as the outside; one end of the metal strip/sponge strip is above the mask.
3. Do not squeeze the mask with your hands. The mask can only isolate the virus on the surface of the mask. If you squeeze the mask with your hands, the virus will soak through the mask with the droplets, and you may get the virus.
4. Try to make the mask and the face have a good fit. The simple test method is: After putting on the mask, exhale forcefully so that air cannot leak from the edge of the mask.
