The structure of disposable masks is two layers of non-woven fabric with a filter material sandwiched between them, and the filter material can filter most bacteria and viruses to a certain extent. The structure of the medical mask is special, near the skin is pro-skin material, is not irritating to the skin material, the middle can filter most bacteria and viruses, is a high-density material, outside is a kind of anti-bacterial material, and at the same time to prevent liquid spray, medical masks at the bridge of the nose there is a special structure, is in order to and the skin can fully fit. So the two are actually not the same. Content source: Dr. You Lai
