A fan in a fluid conduit draws odor-laden air from the internal environment and passes it through an ozone-rich vicinity provided for example by one or more ozone generators, then exhausts the treated deodorized air to the external environment. Fresh air is introduced into the negative-pressure enclosure from the external environment through one or more gaps or cervices in the structure. ## Claims ### Claim 1 An apparatus for reducing scent emanating from a substantially enclosed structure’s internal environment to the external environment, the apparatus comprising. ### Claim 2 A fluid conduit between the internal environment and the external environment. ### Claim 3 A descenting agent source within the fluid conduit; and. ### Claim 4 A fan within the fluid conduit configured to exhaust air from the internal environment to the external environment. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the descenting agent comprises ozone. ### Claim 6 (depends on 2) The apparatus of claim 2 wherein the ozone is provided by an ozone generator. ### Claim 7 (depends on 3) The apparatus of claim 3 wherein the ozone generator is located within a housing, said housing comprising an inlet port fluidly connected to the internal environment and an outlet port fluidly connected to the external environment. ### Claim 8 (depends on 4) The apparatus of claim 4, wherein the fan is located within the housing. ### Claim 9 (depends on 4) The apparatus of claim 4, wherein the fan is located proximate to the inlet port. ### Claim 10 (depends on 4) The apparatus of claim 4, wherein the fan is located proximate to the outlet port. ### Claim 11 (depends on 4) The apparatus of claim 4, wherein the housing is configured to be mounted on a sidewall of the substantially enclosed structure. ### Claim 12 (depends on 8) The apparatus of claim 8, wherein the mounting configuration comprises a retainer encircling the fluid conduit proximate the outlet port. ### Claim 13 (depends on 1) The apparatus of claim 1, wherein the fluid conduit comprises PVC pipe. ### Claim 14 (depends on 1) The apparatus of claim 1, wherein the fluid conduit comprises flexible ducting. ### Claim 15 (depends on 4) The apparatus of claim 4, wherein the housing is configured to be suspended within the substantially enclosed structure. ### Claim 16 (depends on 3) The apparatus of claim 3, wherein the fan and the ozone generator are electrically connected to one or more power sources. ### Claim 17 (depends on 13) The apparatus of claim 13, wherein the rate of ozone generation is variable. ### Claim 18 A method of reducing scent emanating from a substantially enclosed structure’s internal environment to the external environment, the method comprising. ### Claim 19 Providing a fluid conduit having an inlet located inside the structure and an exhaust outlet outside the structure. ### Claim 20 Providing a descenting agent at one or more vicinities within the fluid conduit. ### Claim 21 Producing lower air pressure at the inlet relative to air pressure at the outlet. ### Claim 22 Deodorizing air from the internal environment as it moves through the one or more vicinities in the fluid conduit; and. ### Claim 23 Exhausting deodorized air to the external environment. ### Claim 24 (depends on 15) The method of claim 15, wherein the descenting agent comprises ozone. ### Claim 25 (depends on 16) The method of claim 16, wherein the ozone is provided by one or more ozone generators. ### Claim 26 (depends on 17) The method of claim 17, wherein the air pressure differential is produced by a fan located within the fluid conduit. ### Claim 27 (depends on 18) The method of claim 18, wherein the fluid conduit comprises a housing that encloses the fan and at least one ozone generator. ### Claim 28 An apparatus for reducing scent emanating from a substantially enclosed structure’s internal environment to the external environment, the apparatus comprising. ### Claim 29 A fluid conduit having an inlet inside the structure and an exhaust outlet outside the structure. ### Claim 30 A housing comprising an inlet port fluidly connected to the inlet and an outlet port fluidly connected to the exhaust outlet. ### Claim 31 A retainer configured to secure the housing to a wall of the structure. ### Claim 32 A variable output electric ozone generator configured to generate an ozone-rich vicinity within the housing; and. ### Claim 33 A variable speed electric fan located within the housing, said fan configured to draw air from the internal environment at the inlet and exhaust the air to the external environment at the exhaust outlet after the air passes through the ozone-rich vicinity. ### Claim 34 Wherein at least one of (the inlet port and the outlet port) is configured for convenient attachment and detachment to a standard-dimension PVC pipe.
