The medical mask is composed of a mask body and a tension belt. The mask body is divided into inner, middle and outer layers. The inner layer is skin-friendly raw material, the middle layer is an isolation filter layer, and the outer layer is a special material antibacterial layer. This high-efficiency medical mask has strong hydrophobicity and air permeability, and has a significant filtering effect on small virus-bearing aerosols or harmful dust, but cannot effectively filter PM10 and PM2.5. The overall filtering effect is excellent, and the materials used are non-toxic and harmless. Comfortable to wear.
There are many types of medical masks. Common medical masks are disposable non-woven masks and gauze masks. They are mainly made of special raw materials, with a filter layer in the middle. Generally, the filter layer is made of activated carbon felt or meltblown cloth. Disposable masks can only be used once, cannot be reused, and must be used within the useful period. After use, they should be placed in a special storage bin, and should not be thrown around casually to avoid the spread of the virus. Disposable masks should be stored in an environment where the relative humidity does not exceed 80%, in a room with no corrosive gas and good ventilation, and avoid high temperature.
