The guard further comprises at least one agent stored in the one or more compartments wherein the at least one agent may be a counteracting agent, a masking agent or a disinfectant agent. The masking agent may be coffee, oil and self encapsulated oil beadlet. The counteracting agent may be activated charcoal, sodium bicarbonate, zeolite, diatomaceous earth, silica gel and bentonite clay. The disinfectant agent may be a water based coating containing a cationic siloxane. In another embodiment of the invention the compartments may store the agents in a portion of the guard that is adapted to come in contact with the wearer's nostrils. ## Claims ### Claim 1 An air-permeable guard adapted to attach to a covering, the air permeable guard comprising: a plurality of layers attached, together to create one or more compartments; at least one agent stored in a first compartment holding one agent adapted to fit a left nostril and a second compartment holding same or different agent adapted to fit a right nostril; and wherein the at least one agent may be a counteracting agent, a masking agent or a disinfectant agent. ### Claim 2 (depends on 1) The air-permeable guard of claim 1 wherein the covering is a surgical mask and wherein the air permeable guard is further adapted to fit a human face. ### Claim 3 (depends on 2) The air-permeable guard of claim 2 wherein the plurality of layers are comprised of one or more material selected from the group consisting of paper, cloth, plastic, or fiber. ### Claim 4 (depends on 3) The air-permeable guard of claim 3 wherein the plurality of layers are attached together with an adhesive. ### Claim 5 (depends on 3) The air-permeable guard of claim 3 wherein the plurality of layers are attached together by bond heating the plurality of layers. ### Claim 6 (depends on 3) The air-permeable guard of claim 3 wherein the plurality of layers are attached together by stitching the plurality of layers. ### Claim 7 (depends on 6) The air-permeable guard of claim 6 wherein the plurality of layers comprises three or more layers wherein the three or more layers form two or more compartments. ### Claim 8 (depends on 7) The air-permeable guard of claim 7 wherein a masking agent is stored in a first compartment and a counteracting agent is stored in the second compartment. ### Claim 9 (depends on 8) The air-permeable guard of claim 8 wherein the masking agent is coffee. ### Claim 10 (depends on 6) The air-permeable guard of claim 6 wherein the plurality of layers comprises five layers, the first layer adapted to fit a human face, the second and third layers adapted to store between 0.5 and 2.5 grams of ground coffee, the third and fourth layers adapted to store between 0.1 and 2.5 grams of activated charcoal and 0.1 to 5 grams of sodium bicarbonate, and wherein the plurality of layers are rectangular in shape. ### Claim 11 (depends on 1) The air-permeable guard of claim 1 wherein the counteracting agent is selected from the group consisting of, sodium bicarbonate, zeolite, diatomaceous earth, silica gel and bentonite clay. ### Claim 12 (depends on 11) The air-permeable guard of claim 11 wherein a disinfectant agent is stored in one of the two or more compartments and wherein the disinfectant agent is a water based coating containing a cationic siloxane. ### Claim 13 (depends on 1) The air-permeable guard of claim 1, wherein the first and second portions of the first compartment are stitched closed. ### Claim 14 (depends on 13) The air-permeable guard of claim 13 therein the guard is attached to the surgical mask with an adhesive.
