A biohazard mask for civilian use comprises bidirectional HEPA filtering
to protect both personal and public health during an outbreak. Several
measures are taken to maximize comfort and wearability, such as
comfort-fit through a gel seal, anti-fogging protection through
separation of the eye volume from the mouth-nose volume and through eye
moisture release valves, heat-dissipation through a net suspension, and
overpressure release valves to maintain the face seal during coughing or
sneezing. Wicking exhalation filters promote moisture abatement around
the mouth and nose. Attractive and stylish designs, combined with
accommodation for telephone communication or audio entertainment, helps
wearers keep the mask on during an outbreak.
