Material preparation: disposable mask.
1. First, fold the mask in half and tie a knot on the ear rope. This knot is tied at the innermost part, and the ropes on both sides are also tied with a knot. These two knots are used to fix the shape of the mask.
2. Then, press both sides of the mask inward to make it a corner, and press both corners in. When finished, it looks like a ship.
3. Then, open the inside of the mask, flatten the corners on both sides, and adjust the bridge of the nose to make the inside of the mask oval, so that the disposable mask is deformed.
4. When wearing this mask, the front position of the mask will be raised, and the shape is similar to that of N95 mask. When wearing this mask, the sealing around the mask will be better, thus improving the protection of the mask. If you wear a disposable mask normally as usual, the sealing will not be as good as this.
5. Usually used in an emergency, if a friend thinks this mask is not beautiful, he can also wear a disposable mask, put the modified mask inside and put the other mask outside, so wearing two masks at a time will make the protection more strict.
