In general, the protective effect of disposable medical masks is better than that of disposable masks. Disposable medical masks need to meet YY / t0969 standard, which is a mask with a lower level of protection than medical surgical masks. It can be used in non epidemic period, second and third line personnel in hospital or medical occasions with lower protection level.

      The civil masks are all plane masks, which are one level lower than the disposable medical masks. The structure of the masks is the same as that of disposable medical masks, but the melt blown cloth used in the middle is ordinary melt blown cloth without electret treatment, and only has the barrier effect of droplets. If the fiber is made smaller, it can also block bacteria for a short time, but there is no adsorption force between the charges. When inhaled, bacteria will enter the body with the pressure difference, and the protection effect is general.
