Abstract: A reusable, porous mask with a concealed respiratory filter and exhalation valves is provided. The mask comprises a flexible porous outer frame, a detachable semi-rigid respiratory filter that nests within the outer frame, and one or more exhalation valves attached to the respiratory filter so they are concealed behind the outer frame. The mask is flexible enough to be folded to fit inside a pocket or purse. The mask has the capability of enhancing the lives of people with respiratory disorders, people who wish to minimize their exposure to chemicals, particles and germs, and professionals who require respiratory protection.
