Abstract

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.
