The disclosed airflow treatment device can also be maintained substantially free of any interruptions, disassembly or downtime to the air handling system after initial inline installation of the disclosed device. In one arrangement, the airflow treatment device is capable of accepting a threaded odor neutralizer container at its base. Ductwork need only be disassembled once to attach the disclosed device inline in the airflow path of the ductwork. When the odor neutralizing agent needs replenished, the container can be detached from the device, replenished, and reattached to the device free of disruption to the air flow of the air handling system. ## Claims ### Claim 1 A kit for use in treating airflow in ductwork, comprising: an airflow treatment device, including: a first body including a first wall having inner and outer surfaces, wherein the inner surface defines an airflow passageway, and wherein the first wall includes first and second opposite open ends, and wherein the airflow passageway extends between the first and second opposite open ends of the first wall; and a second body including a second wall that defines a first portion of an air treatment passageway that intersects the airflow passageway, wherein the second wall includes first and second opposite open ends, wherein the first portion of the air treatment passageway extends between the first and second opposite open ends of the second wall, wherein the first open end of the second wall is disposed outside of the airflow passageway; a first securement member for releasably securing the first open end of the first body to a first duct of the ductwork; a second securement member for releasably securing the second open end of the first body to a second duct of the ductwork; and an air treatment container that is one of releasably securable or releasably secured to the first open end of the second wall, wherein the air treatment container includes a third body having a third wall that defines a second portion of the air treatment passageway that feeds into the first portion of the air treatment passageway, wherein the third wall includes a closed first end and an opposite open second end, and wherein the second portion of the air treatment passageway extends between the closed first end and the opposite open second end of the third wall; wherein the airflow passageway includes an airflow passageway axis extending between the first and second opposite open ends of the first wall, and wherein the air treatment passageway includes an air treatment passageway axis that extends between and through the first closed end and the opposite open second end of the air treatment container and also between and through the first and second opposite open ends of the second wall. ### Claim 2 (depends on 1) The kit of claim 1, wherein the airflow treatment device includes a first releasable interconnection apparatus and wherein the air treatment container includes a second releasable interconnection apparatus that is complimentary to the first releasable interconnection apparatus. ### Claim 3 (depends on 1) The kit of claim 1, wherein the second open end of the second wall extends into the airflow passageway by an amount equal to at least 5% of an inner maximum cross-dimension of the airflow passageway and not more than 50% of the inner maximum cross-dimension of the airflow passageway. ### Claim 4 (depends on 1) The kit of claim 1, further including: an adapter that releasably secures the air treatment container to the second body. ### Claim 5 (depends on 4) The kit of claim 4, wherein the adapter includes a fourth body having a fourth wall that defines a third portion of the air treatment passageway that intersects the first and second portions of the air treatment passageway, wherein the fourth wall includes first and second opposite open ends, wherein the third portion of the air treatment passageway extends between the first and second opposite open ends. ### Claim 6 (depends on 5) The kit of claim 5, wherein the fourth body includes a first releasable interconnection apparatus that is releasably interconnectable with the third body, and a second releasable interconnection apparatus that is releasably interconnectable with the second body. ### Claim 7 (depends on 1) The kit of claim 1, wherein the airflow passageway axis is perpendicular to the air treatment passageway axis. ### Claim 8 (depends on 1) The kit of claim 1, wherein the first securement member is a hose clamp. ### Claim 9 (depends on 1) The kit of claim 1, wherein the second securement member is a hose clamp. ### Claim 10 (depends on 1) The kit of claim 1, wherein the airflow passageway axis is non-perpendicular to the air treatment passageway axis. ### Claim 11 A kit for use in treating airflow in ductwork, comprising: an airflow treatment device, including: a first body including a first wall having inner and outer surfaces, wherein the inner surface defines an airflow passageway, and wherein the first wall includes first and second opposite open ends, and wherein the airflow passageway extends between the first and second opposite open ends of the first wall; and a second body including a second wall that defines a first portion of an air treatment passageway that intersects the airflow passageway, wherein the second wall includes first and second opposite open ends, wherein the first portion of the air treatment passageway extends between the first and second opposite open ends of the second wall, wherein the first open end of the second wall is disposed outside of the airflow passageway; a first securement member for releasably securing the first open end of the first body to a first duct of the ductwork; a second securement member for releasably securing the second open end of the first body to a second duct of the ductwork; an air treatment container that is one of releasably securable or releasably secured to the first open end of the second wall, wherein the air treatment container includes a third body having a third wall that defines a second portion of the air treatment passageway that feeds into the first portion of the air treatment passageway, wherein the third wall includes a closed first end and an opposite open second end, and wherein the second portion of the air treatment passageway extends between the closed first end and the opposite open second end of the third wall; and an adapter that releasably secures the air treatment container to the second body, wherein the adapter includes a fourth body having a fourth wall that defines a third portion of the air treatment passageway that intersects the first and second portions of the air treatment passageway, wherein the fourth wall includes first and second opposite open ends, wherein the third portion of the air treatment passageway extends between the first and second opposite open ends, wherein the fourth body includes a first releasable interconnection apparatus that is releasably interconnectable with the third body, and a second releasable interconnection apparatus that is releasably interconnectable with the second body wherein the first releasable interconnection apparatus is a first set of threads and wherein the second releasable interconnection apparatus is a second set of threads. ### Claim 12 (depends on 1) A system, comprising: the kit of claim 1;
