Wash your hands before wearing a mask, or avoid touching your face with the inside of the mask during wearing the mask to reduce the possibility of the mask being contaminated. 2. Distinguish the inside and outside of the mask, up and down. 3. Do not squeeze the mask with your hands. The mask can only isolate the pollution on the surface of the mask. If you squeeze the mask with your hand the pollution will wet the mask with the droplets, which will easily cause infection. 4. Try to make the mask fit tightly to the face. The simple test method is: after putting on the mouth, the ribs exhale and the air cannot leak out from the edge of the mouth. 5.The protective mask must be close to the user's face, the user must shave the beard to ensure that the mask can fit tightly to the face, and the beard and anything placed between the mask seal and the face will cause the mask to leak. 6.After adjusting the position of the mask according to your face shape, press the nose clip along the upper edge of the C mask with the index fingers of both hands so that it fits tightly on the face
