A face mask to be worn upon the face of a wearer and for providing filtering of particular impurities in the air, including at least one pre-bonded composite layer formed by a combination of flexible plastic material and a non-woven fabric and with the pre-bonded composite layer molded generally to conform to the contours of the face of the wearer and forming a flexible support carrier for filter material and with the one pre-bonded composite layer providing a plurality of perforations through the one pre-bonded composite layer for allowing the free passage of air through the one pre-bonded composite layer while preventing the passage of liquid from a position outside the face mask, and a separate layer of filter material supported by the one pre-bonded composite layer and with the filter material filtering out the particular impurities in the air. |
