| Abstract: |
A face mask is provided that includes a filter body capable of filtering liquids, particles and aerosols of a size appropriate for the mask's intended purposes, while providing excellent breathability and comfort for extended periods of time. The filter body may be formed from multiple layers of filtration material having a generally rectangular configuration with a plurality of pleats. The mask may be secured to the head of a wearer by tie strips attached to flaps extending from the filter body to form a fluid seal between the periphery of the mask and the wearer's face. For some applications, the flaps may be formed from resilient or stretchable material which further enhances both the fluid seal formed by the mask and comfort for the wearer. A clear visor may also be attached to the mask to protect the wearer's eyes and portions of the wearer's face not covered by the mask.

What is claimed is:
1. A surgical style face mask comprising:
- a non-molded flexible filter body sized to fit over the mouth and nose of a wearer, the filter body having top and bottom edges with the top edge arranged to extend across the nose and cheeks of the wearer and the bottom edge arranged to extend under the chin of the wearer, and said filter body having multiple pleats and a generally rectangular configuration, and an elongated malleable member located in the top edge for conforming the top edge to the contours off the wearer's nose and cheeks;
- a flap attached to each side of the filter body and arranged to extend from the filter body;
- each flap formed from flexible material that is different from the material used to form the filter body;
- means for gathering said flaps into sealing contact with a wearer's face, said means for gathering comprising first securing means and second securing means attached to the respective flaps and arranged to extend generally about the head of the wearer, the first and second securing means extending through the flaps for urging the top edge and the bottom edge into tight engagement with the face of a wearer and for gathering said flexible flap material to prevent undesired fluid flow between the top edge, the bottom edge between the respective sides of the filter body and the face of the wearer.
