1, identify the direction of the mask and cover it on the nose, mouth and chin. If you want to wear a head-mounted N95 mask, you need to distinguish the direction of the mask first, and make sure that the metal nose clip of the mask faces outwards. Next, put the mask on your nose and mouth, let it hold your chin and fix it with one hand.

2. Pull up two hair bands. The head-mounted N95 mask has two headbands, one at the top and the other at the bottom. You need to pull the headband below your head first, and then put it behind your neck and under your ears. The headband above is pulled over your head and placed on the back of your head, above your ears. Make sure that the two headbands are in the right position, and don't just use one headband, otherwise the tightness will be greatly reduced.

3. Press the metal nose clip. After wearing the headband, you need to press the metal nose clip. Press your hands and fingers in the center of the nose clip and slowly move to both sides so that it can be tightly attached to the bridge of the nose. After pressing, confirm the correct wearing position and check the air tightness, as long as there is no obvious air leakage.
