Abstract: A canine mask is provided for filtering air pollution from inhaled air. A main body of the mask may comprise flexible/semi-flexible material that is formed in a generally hollow cylindrical-, hollow frustrum-, or hollow frustoconical-shape. The proximal end of the main body may comprise strap(s) providing a securing mechanism, and the distal end may provide a panting valve. An adjustment mechanism may be provide near the proximal end to allow adjustment of muzzle circumference. The main body may provide a filter pocket where an air filter may be placed to filter inhaled air, whereas the panting valve allows exhaled air to exit. When properly placed and secured on a canine's snout, the mask forms a seal so that exhaled air exits the panting valve and inhaled air only enters through the air filter cleaning incoming air of pollutants.
