How to wear headbands masks?

How to wear ear-loops masks?

1) Face the side without the nose clip, and pull the ear straps with both hands, so that the nose strip faces up;

2) Let the mask against your chin;

3) Pull the ear straps to the back and adjust them to feel comfortable;

4) Starting from the middle of the metallic strip with both index fingers, press down on it while moving to both sides to shape the shape of the bridge of the nose. Pinching the nose strip with one hand will cause sharp angles and air leakage, and reduce shielding performance. The nose strip should be pressed with both sides at the same time.

Whether it is a headbands or ear-loops mask, an air impermeability test is required after wearing. Cover the mask with both hands and breathe. If you feel that gas leaks from the nose strip, you should readjust it. If you feel that gas leaks from both sides of the mask, you need to further adjust the position of the headbands and earloops; if it still leaks, you need to change another one.
