The airtightness of the cup-shaped mask is the best among the three types. Because the appearance design of the mask is concave and convex, and there is an airtight pad on the nose bridge of the mask, it is more comfortable to wear while ensuring the airtightness of the mask.
How to wear a cup mask
1. Hold the medical mask in your hand, with the nose clip at your fingertips, and let the headband hang under your hand.
2. Make the mask support the chin and cover the nose.
3. Hold the position of the medical mask with your hands, place the upper headband above the ears and higher behind the head, and place the lower headband below the ears of Jinhou.
4. Put the tips of your two fingers on the metal nose clip, starting from the middle position, press the nose clip with your fingers inward, and move and press it to both sides respectively to shape the nose clip according to the shape of the nose bridge.
Remember, no matter what type of mask, after wearing the mask correctly, you must check the air tightness of the positive pressure wearing mask. Cover the mask completely with both hands and exhale quickly. If there is a gas leak on the edge of the mask, the nose clip and headband must be readjusted, and the wearing air tightness check must be repeated. It is very important to firmly press the nose clip on the face to form a good fit.
Master the correct way to wear a mask as required. The mouth and nose are completely close to the inner wall of the mask, and there should be no gaps to prevent dust from entering the lungs through the mouth and nose. When buying a mask, you must first understand the way the mask is worn, the filtering efficiency of the mask, and the brand of the mask. The use of the mask must be clean, especially the parts in contact with the mouth and nose.
