摘要： A face mask including a face-contacting layer (12), an outer cover layer (14), a polymeric microfiber mat (16) disposed between the face-contacting layer and the outer cover layer, and a non-woven fibrous mat disposed between the face-contacting layer and the outer cover layer. The non-woven fibrous mat (18) includes polymeric fibers and a surface energy reducing agent. The face-contacting layer (12), the cover layer (14), the polymeric microfiber mat (16), and the non-woven fibrous mat (18) cooperate with each other to allow gas to pass through the mask while inhibiting the passage of liquid through the mask.
