Patent

CA 2741799

The invention is directed to a protective mask that has high filtration efficiency, yet is easy to breathe through and is comfortable to wear. The mask includes a thin filter body layer configured to cover the mouth and nose of a user when the mask is worn and a thicker compressible gasket positioned along a periphery of the mask. The gasket comprises a high loft, porous dielectric filtering material that forms a breathable closure about the user's face without forming an airtight seal, such that the user can draw breathable air from the sides, top, and bottom of the mask. The mask preferably includes a outer scrim coated with biocidal iodinated resin to provide surface antibacterial properties.
