They can block blood and body fluids from passing through the mask to contaminate the wearer, and at the same time, the filtration efficiency of bacteria is more than 70%. The filtration efficiency of the mask is limited, and most of them are rectangular in design, and the fit with the face is not as tight as that of medical protective masks.

1. Put the light-colored side close to our face. In addition, the end with the metal strip is above the mask, and then hang the ropes at both ends on the ears. 2. 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 does not leave any wrinkles.
