ABSTRACT What is disclosed is a face mask formed from a porous sheet made of a plurality of fibers. The mask is formed into a generally cup shape shell that fits over the mouth and nose of the wearer and is held thereto by elastic straps attached to the mask that pass behind the head when the mask is worn. The mask filters breathed air passing through the mask. The border of the mask is more tightly compacted during forming. The mask of the present invention features rearwardly projecting portions located on either side of the nose bridge area of the mask parallel to and close to the border of the mask. The peak of the rearwardly projecting portions extend from the face mask in the direction of the face of the wearer of the mask to conform the portion of the mask close to its border to the contours of the face of the wearer between the bridge of the wearers nose and the upper areas of their cheekbones. The more tightly compacted rearwardly projecting portions, rib elements and border cooperate to provide shape retention to the mask, and to provide a spring action that holds the mask firmly but comfortably to the face of the wearer even when they talk or change facial expression to prevent the passage of air between the mask and the face of the wearer.
