A respiration filtering face mask that can be washed and sterilized by common means and reused repeatedly comprised of a filtering component that is a laminate of at least one layer of particle filtering material and at least one layer of a microbe killing metallic woven cloth laminated together by adhesive or fusible material in a manner that allows low resistance to air flow, cut to a shape that is folded into a modified cone, a padding filled gasket that is continuously sealed to the outer edge of the filter cone, harness straps that are elastic and user adjustable for length and tension, and an attached shield to prevent fogging of eye ware. A method for making said anti-microbial filter and respiration filtering face mask.

Disclosed herein is a shelf-stable, two-part formula for making an antimicrobial biphasic polymer. Some variations provide a two-part formula for fabricating a biphasic polymer, wherein the two-part formula consists essentially of (A) a first liquid volume, wherein the first liquid volume comprises: a structural phase containing a solid structural polymer; a transport phase containing a solid transport polymer; a chain extender; a curing catalyst; a first solvent; and (B) a second liquid volume that is volumetrically isolated from the first liquid volume, wherein the second liquid volume comprises: a crosslinker that is capable of crosslinking the solid structural polymer with the solid transport polymer; and a second solvent. An antimicrobial agent (e.g., quaternary ammoniums salts) may be contained in the first liquid volume or in the second liquid volume. Methods of making and using the antimicrobial biphasic polymer are described.
