Not only that, the mask is also divided into upper and lower, there is a metal bar feel hard side is the top, wear is close to the bridge of the nose.


After understanding the basic structure of the mask, let's learn how to wear the mask properly.

  1. Wash: First, Wash your hands so that dirty hands will not contaminate the inside of the mask;

  2. Second, Hang: put the mask across your face, nose and mouth, and use your hands to hang the two ends of the rope over your ears; keep the light side of your face close to ours; and, one end of the metal strip is above the mask, and the two ends of the string are hung over the ears.

  3. Three, pull: Both hands up and down direction of the folds of the mask, so that the mask can completely cover the mouth and nose and Chin;

  4. four, pressure: Finally, with both hands of the forefinger pressure on the nose on both sides of the metal bar, so that the upper end of the mask can be close to the nose. 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 it does not leave folds.


  1. 洗:首先,清洗双手,以免不干净的手污染口罩内面;

In addition, it is important to note that after wearing a mask, avoid touching the mask frequently in order to avoid reducing its protective effect; after taking off the mask, wrap it in a tape or paper bag, then dispose of it in a covered dustbin, and wash your hands in a timely manner; Do not reuse disposable masks.


The fitting effect of the mask:

The mask must be the right size, wear the way must be correct, the mask will be effective. The masks sold on the market are generally divided into rectangular and cup-shaped two. A rectangular mask must have at least three layers of paper to provide protection. Users have to put the wire mask on the bridge of the nose, and then along the bridge of the whole mask will be spread out, to play the role. The child can wear a rectangular surgical mask, because it is not fixed shape, if tied properly, can be close to the child's face. Cup-shaped mask to ensure that the density of the mask against the face is sufficient, the air will not leak out to be effective. When you wear a cup-shaped mask, try blowing with both hands over the mask to check for air leakage from the edge of the mask. If the mask cover is not tight, you have to reposition it before wearing.
