Facemask with filtering closure
View Patent ↗There is provided a protective media and a method of manufacturing the same. In one aspect, the protective media includes a porous dielectric carrier, an active agent incorporated in the porous dielectric carrier, and an electrostatic charge across at least a portion of the porous dielectric carrier. This innovative media is capable of eradicating microorganisms and/or toxins more efficiently than prior art solutions and can also self sterilize.
1. A combination comprising:
a facemask having a periphery adapted to abut a user's face; and a compressible gasket formed of a breathable filtering material on said periphery of said facemask adapted to provide an air path there through and to sit between said periphery of said facemask and a face of a user thereby filling any space that may exist there between: said facemask having an area for filtering air which is interior to said periphery and not covered by said gasket.
2. The combination as in claim 1 wherein said compressible gasket includes an active agent incorporated therein.
3. The combination as in claim 2 wherein said active agent is selected from the group consisting of metals and chemical compounds.
