The retaining member may include a flexible elongated body having a central portion and opposing ends, and a bottom surface arranged to be attached to the respiratory mask. The liner may include a liner body constructed from an absorbent material and having an outer edge, an inner edge, and an opening bounded by the inner edge, wherein an extending portion of the liner body is defined which extends outwardly beyond the face-engaging portion and includes at least one aperture for engaging the retaining member. A kit for use with a respiratory mask includes at least one liner and at least one retaining member. ## Claims ### Claim 1 A respiratory mask, comprising: a mask body having a face-engaging portion; and at least one retaining member connected to the mask body, the at least one retaining member including a flexible elongated body and at least one engaging member, the at least one engaging member having a proximal end and a distal end, the at least one engaging member extending upwardly from the flexible elongated body at the proximal end and then outwardly beyond a perimeter of the flexible elongated body at the distal end, the at least one engaging member configured for receiving a liner and tethering the liner to the respiratory mask to generally overlie the face-engaging portion. ### Claim 2 (depends on 1) The respiratory mask of claim 1, wherein the at least one retaining member is removably attached to the mask body. ### Claim 3 (depends on 1) The respiratory mask of claim 1, wherein the at least one retaining member is integrally formed with the mask body. ### Claim 4 (depends on 1) The respiratory mask of claim 1, wherein the at least one engaging member includes a hook. ### Claim 5 (depends on 1) The respiratory mask of claim 1, wherein the at least one engaging member includes two spaced engaging members extending from the flexible elongated body. ### Claim 6 A retaining member for use with a respiratory mask, comprising: a flexible elongated body having a central portion and opposing ends on either side of the central portion, the flexible elongated body having a bottom surface arranged to be attached to the respiratory mask; and at least one engaging member having a proximal end and a distal end, the at least one engaging member extending upwardly from the flexible elongated body at the proximal end and then outwardly beyond a perimeter of the flexible elongated body at the distal end, the at least one engaging member configured for receiving a liner and tethering the liner to the respiratory mask. ### Claim 7 (depends on 6) The retaining member of claim 6, wherein the at least one engaging member includes at least one hook. ### Claim 8 (depends on 6) The retaining member of claim 6, wherein the central portion is narrower than the opposing ends. ### Claim 9 (depends on 6) The retaining member of claim 6, wherein the central portion includes a marker for identifying a center of the flexible elongated body. ### Claim 10 (depends on 6) The retaining member of claim 6, wherein the at least one engaging member includes two spaced engaging members extending from the flexible elongated body. ### Claim 11 A kit for use with a respiratory mask, comprising: at least one liner including a liner body constructed from an absorbent material, the liner body having an outer edge, an inner edge, and an opening bounded by the inner edge, wherein the liner body includes at least one aperture; and at least one retaining member arranged to be connected to the respiratory mask, the at least one retaining member including a flexible elongated body and at least one engaging member, the at least one engaging member having a proximal end and a distal end, the at least one engaging member extending upwardly from the flexible elongated body at the proximal end and then outwardly with respect to the flexible elongated body at the distal end, the at least one engaging member configured for receiving the at least one aperture of the liner and tethering the liner to the respiratory mask. ### Claim 12 (depends on 11) The kit of claim 11, wherein the at least one engaging member includes a hook. ### Claim 13 (depends on 11) The kit of claim 11, wherein the at least one aperture includes a first pair of spaced apertures adjacent a first end of the liner. ### Claim 14 (depends on 11) The kit of claim 11, wherein the at least one aperture includes a first pair of spaced apertures adjacent a first end of the liner and a second pair of spaced apertures adjacent a second end of the liner. ### Claim 15 (depends on 11) The kit of claim 11, wherein the liner includes at least one tab extending outwardly from the outer edge of the liner body. ### Claim 16 (depends on 15) The kit of claim 15, wherein the at least one tab includes an aperture. ### Claim 17 (depends on 11) The kit of claim 11, wherein the liner body includes a notch at one end thereof. ### Claim 18 (depends on 11) The kit of claim 11, wherein the at least one engaging member includes two spaced engaging members extending from the flexible elongated body.
