A device includes a face mask having an exterior surface, an interior surface, a central aperture extending from the exterior surface to the interior surface, and a perimeter. The face mask is adapted to overlay a user's mouth and nose such that the perimeter forms an air-tight seal with the user's face. The device also includes an outer layer overlaying the face mask and having a pair of straps with inter-engaging ends for affixing the face mask about the user's face. The device also includes an insert adapted to be received within the central aperture of the face mask in an air-tight manner. The insert includes an exterior surface, an interior surface, a first portion adapted to prevent the user from inhaling therethrough and to allow the user to exhale therethrough, a second portion adapted to filter air inhaled therethrough, and a cap overlaying said first and second portions.
