Medical Face Mask

a single-use medical product that covers the mouth and nose of the wearer and serves a barrier for direct transmission of infectious particles from the mask wearer to other people around. A modern mask commonly consists of a filter layer (MELT BLOWN), which is settled between the two outer layers of non-woven material (spunbond), plus a flexible aluminum insert that maintains a snug fit mask in the shape of a nose [1]. The mask is fixed upon the face with elastic ear loops.
