Abstract
A facemask assembly includes one or more airflow vents in a lower front section of the mask as well as within the nasal area. The airflow vent allow for the outflow of exhaled heat and CO2. The airflow vents can be configured to direct inward airflow to strike an interior air filter. In some embodiments the airflow strikes the air filter at an oblique angle. The particulate capturing air filter can be replaceable. In some embodiments the air filter contains biocidal elements. In some embodiments the internal filter design enhances the capture of exhaled H2O which activates silver ions in the filter material creating a biocidal environment. In some embodiments, the facemask has two snap-in zones—one below the nose and one under the chin that can accommodate a wide variety of straps/tubing/O-ring stock and be secured behind the head via tying or various cord locks.
