How to distinguish the front and back of disposable activated carbon mask and how to wear it?

Refer to venetian blinds to distinguish the front and back of the mask. On the outside of the blinds are leaves facing down, which provides shade and rain protection. The mask is the same, the outer side is also folded down, so pick up the mask, the side with the pressure belt is on it, and then look at the folding, and the downward side is the front.

Wearing method:

1 Both disposable masks and medical masks have two sides. Take the disposable mask as an example, the dark color is the front, and the front should be outward. The medical mask has a nose clip metal strip (the metal strip is facing up when worn);

2, facing the face should be the opposite of the medical mask, that is, the lighter side. It should also be noted that the part with metal strip should be above the mask. Don't wear it backwards.

3. After distinguishing the front, back, upper end and lower end of the mask, wash your hands first, and then hang the ropes at both ends on your ears after confirming whether the mask is correct.

4. The last step, which is also the most important step, is also the metal bar problem mentioned above. After wearing the mask, you need to press the metal strips on both sides of the bridge of the nose with both hands, so that the upper end of the mask is close to the bridge of the nose, and then stretch the mask downward, so that the mask will not wrinkle, and it is best to cover the nose and mouth, so that the effect of the medical mask will be better.

Extended data

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 between inside and outside the mask, up and down.

3. Don't squeeze the mask with your hands. N95 mask 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, which is easy to cause virus infection.

4. Try to make the mask fit the face. The simple test method is: after wearing the mask, exhale forcefully, and the air cannot leak from the edge of the mask.
