Disposable general masks are generally made of two layers of 28g non-woven fabric with an environmentally friendly full plastic strip at the nose bridge. Medical surgical masks, on the other hand, are generally made of non-woven material, including the filter layer, mask band and nose clip. In addition, because disposable ordinary masks can only filter the air entering the mouth and nose to block harmful gases, odors and droplets, they are suitable for use in electronic factories, food service industry, daily life and other scenarios. Medical surgical masks, on the other hand, are suitable for basic protection of medical personnel or related personnel as they can block most bacteria and some viruses, as well as protection to stop the spread of body fluids and splashes during invasive operations.
