Abstract
A reusable two-way respirator mask comprising a filter cover, a filter base, a facepiece, and a filter adapted to remove airborne pathogens. The facepiece is configured to interface with the face of the user and deform under moderate pressure to create a substantially airtight seal with the user's face. The filter cover and filter base a removably coupled such that the user may easily replace the filter by decoupling the filter cover and filter base. Both inhalation and exhalation pass through the filter, reducing the user's inhalation of pathogens and reducing the spread of pathogens from the user to others. The reusable two-way respirator mask is constructed of head resistant materials, suitable for repeated disinfecting.
