Disposable protective masks
First understand the masks, whether it is disposable masks or other masks, there are front and back, as far as disposable masks are concerned, the darker color is the front, and the front is outward. Take a look at the picture below, where the circled in red contains the metal clip of the nose clip.
The reverse side of the disposable mask is lighter in color and the reverse side is inward, which means that the lighter side is close to our face. In addition, please also note that the end with the metal strip is above the mask, do not bring it upside down. After clearly distinguishing the front, back, top, and bottom of the mask, it is not far from the correct wearing of the mask. Wash your hands, make sure that the light-colored side of the mask is facing inward (reverse side), and the end with the metal strip is facing upward (upper side). Hang the rope at both ends on your ears. Seeing this, do you think the mask should be worn Anymore?
The most important step is to use both hands to press the metal strips on both sides of the bridge of the nose so that the upper end of the mask is close to the bridge of the nose. Then stretch the mask downwards so that the mask does not leave wrinkles and better cover the nose and mouth.
