Generally, N95 masks, like other masks, are tied behind the ears. However, in order to fit the various faces of the public, some masks will wear hooks to prevent a few people from falling off easily because of their small faces.
Compared with ordinary masks, N95 masks have obvious advantages in blocking fine particles such as PM2.5 Ordinary masks can only block coarse particles and keep warm, but if they are worn for a long time, they may have difficulty breathing, so they should be worn according to their own specific conditions. If it is not suitable, it is not recommended to wear it.
The hook in N95 can hook the ropes of two masks together, so that the whole mask can be tightly attached to the face without air leakage, which is a humanized design considering different face shapes.
How to wear N90 mask?
1, wash your hands before wearing the mask, or avoid touching the inside of the mask during wearing the mask to reduce the possibility of the mask being contaminated.
2. Distinguish the inside and outside, up and down of the mask; N90 mask with printed edge on the outside; One end of the metal strip/sponge strip is above the mask.
3. Don't squeeze masks, including n95 masks. You can only isolate the virus on the surface of the mask. If you squeeze the mask by hand, the virus will soak the mask in the form of droplets, and there is still a chance to get infected with the virus.
4, be sure to make the mask and face have a good fit. The simple test method is: after wearing the mask, exhale forcefully, and the air cannot leak from the edge of the mask.
