Prevent Fog Mask / Mask

Prevent Fog Mask
Prevent Fog Mask

As a basic hygiene product, masks are widely used in daily life. In ordinary masks, people will feel sultry when wearing them, and it is easy to make breathing uncomfortable. People wearing glasses are also likely to cause glasses to fog due to wearing masks.
Prevent fog mask uses a check valve structure to control the flow of breathing gas, slow down the breathing resistance, and control the direction of exhaled gas discharge; contact the surface of the skin to add quick-drying absorbent fabric to alleviate the condition of the mask due to exhalation.
