Medical surgical masks are relatively thin to the touch, but their filtration efficiency is very high. The three layers of water blocking layer, filter layer and moisture absorption layer effectively block virus invasion.

Although the general cotton masks on the market are thick, they basically do not have the effect of preventing infectious diseases and are unreliable.

As long as it is a regular mask, one is enough!
