Two ear straps: mainly for fixing on the face.
Nose bridge: mainly for shaping.
The arc-shaped reserved layer of the face: It can be opened to form an arc so that the mask will not touch or stick directly to the face.
The first step before wearing a mask is to wash your hands, but when you wear an activated carbon mask, one more action is to remove some small activated carbon particles from the activated carbon mask.
Distinguish that the front and back of the activated carbon mask are different, don’t bring it wrong
On the basis of the above parts, fix the mask on the face with ear straps, and adjust the curvature of the mask to be more comfortable.

Adjust the air tightness of the chin and mask
