The respirator mask has a filter that extends around at least a portion of the perimeter of the mask itself, leaving a central area that coincides with the position of the wearer's mouth unobstructed. A front panel of the mask may be transparent over at least the central area in order to allow the mouth to be seen while the mask is worn. The filter may be a pleated particulate filter, a chemical/gas filter, or a filter of mixed type. The front panel may also include other features, like a port for a drinking straw. The respirator mask may include headgear. ## Claims ### Claim 1 A respirator mask, comprising: sealing structure arranged to seal around at least a nose and mouth of a wearer; a filter cartridge operatively coupled to a front of the sealing structure and configured such that air essentially only enters the respirator mask through the filter cartridge, the filter cartridge including a pleated particulate filter medium and a transparent front cover, the filter cartridge, having the pleated particulate filter medium and the transparent front cover, configured to be removable, the filter medium extending around a perimeter of the filter cartridge, an arrangement of the sealing structure and a portion of the filter cartridge leaving a central area of the respirator mask unobstructed, the central area defined so as to coincide with at least the mouth of the wearer when the respirator mask is worn; the transparent front cover sealed over the central area; a bezel adapted to be releasably attached to a front of the filter cartridge to cover at least a portion of the filter cartridge, the bezel having an opening, wherein the opening coincides with the transparent front cover and leaves the transparent front cover exposed so that at least the mouth of the wearer is visible when the respirator mask is worn; and strap structure adapted to hold the respirator mask in place on a face. ### Claim 2 (depends on 1) The respirator mask of claim 1, the filter cartridge comprising: a perforated inner frame arranged to support the filter medium along an inner aspect thereof; and a perforated outer frame arranged to support the filter medium along an outer aspect thereof, the inner frame and the outer frame being connected together. ### Claim 3 (depends on 1) The respirator mask of claim 1, wherein the bezel covers at least a perimeter of the transparent front cover and extends rearwardly over the filter cartridge. ### Claim 4 (depends on 1) The respirator mask of claim 1, wherein the bezel carries connecting structure for the strap structure. ### Claim 5 (depends on 4) The respirator mask of claim 4, wherein the strap structure holds the bezel in place over the filter cartridge. ### Claim 6 (depends on 1) The respirator mask of claim 1, the strap structure further comprising: a head strap; a neck strap; and an elongate, extensible member connecting the head strap and the neck strap. ### Claim 7 (depends on 6) The respirator mask of claim 6, the strap structure further comprising: a length-adjustment mechanism in the head strap or the neck strap; and a quick-release mechanism in the head strap or the neck strap. ### Claim 8 (depends on 7) The respirator mask of claim 7, the quick release mechanism further comprising: an anchorage; and an anchor that receives the elongate, extensible member; wherein the anchor and the anchorage include complementary engaging structure adapted to allow the anchor and the anchorage to releasably engage one another. ### Claim 9 (depends on 1) The respirator mask of claim 1, wherein the filter medium traverses an entire perimeter of the filter cartridge. ### Claim 10 (depends on 1) The respirator mask of claim 1, wherein the filter medium is shaped, angled, or tapered along multiple planes. ### Claim 11 (depends on 1) The respirator mask of claim 1, further comprising a face shield. ### Claim 12 (depends on 11) The respirator mask of claim 11, wherein the face shield is attached to the strap structure.
