Flat masks, also known as strap-on masks, are mainly used in medical and health fields, such as medical surgical masks.
The adhesion of flat masks is the worst compared to folding masks and cup masks, and basically cannot be used for anti-smog and dust, so it is not recommended for use in dusty environments. The correct way to wear a flat mask is as follows:
1. Medical surgical masks have white and blue sides. Place the white side inward and the side with metal strips upward. First, tie the two lower straps behind the neck and tighten them. The bottom of the mask reaches the base of the chin.
2. Pull up the upper edge of the mask to cover the mouth and nose. The two upper straps are pulled behind the ears and fastened on the head. Those with elastic bands can be fastened to the ears.
3. Use the index fingers of both hands to press the metal wire on the upper nose of the mask to make it close to the skin of the nose, and then gradually move the index finger to the sides, so that the entire mask is close to the facial skin.
4. After taking off the mask, put it in tape or paper bag and put it in a covered trash can for disposal. Wash your hands in time; do not reuse disposable masks.
