1. An apparatus for introducing additive into a fluid stream comprising an additive pod comprising at least one sidewall defining an additive holding chamber and at least one depressible engagement tab extending from the at least one sidewall that is flared at an angle to a longitudinal axis of the additive pod, the engagement tab having a distal portion configured to cooperatively engage with at least one receiving member on an outlet portion of a fluid handling apparatus;at least one additive disposed in the additive holding chamber, wherein the additive holding chamber is configured to disperse the additive into the fluid stream and wherein the additive holding chamber is configured to be disposed in an outlet portion of the fluid handling apparatus,wherein the additive pod has a first at least partially open axial end, a second at least partially open axial end, and the sidewall is a closed wall extending between the first at least partially open axial end and the second partially open axial end that allows fluid to flow into the additive pod along its longitudinal axis and allows fluid to exit the additive pod along its longitudinal axis. 2. The apparatus of claim 1 wherein the at least one sidewall is a substantially cylindrical tube. 3. The apparatus of claim 1 further comprising at least one additive retaining member configured to retain the additive within the additive holding chamber prior to dispersion of the additive into the fluid stream. 4. The apparatus of claim 1 further comprising a downstream trap member configured to prevent portions of non-dispersed additive from escaping the additive holding chamber. 5. The apparatus of claim 1 further comprising a storage container comprising at least one sidewall defining an enclosed volume, wherein the additive pod is disposed within the enclosed volume. 6. The apparatus of claim 5 wherein the additive pod is hermetically sealed within the enclosed volume. 7. The apparatus of claim 1 wherein the additive comprises a sanitizer. 8. The apparatus of claim 7 wherein the sanitizer is selected from the group consisting of chlorine, chlorine dioxide, iodine, hypoiodous acid, bromine, hypobromous acid, hypochlorous acid, fluorine, alcohol, hydrogen peroxide, ozone, and combinations thereof. 9. The apparatus of claim 1 wherein the additive comprises substances selected from the group consisting of flavoring agents, vitamins, dyes, scale inhibitors, and combinations thereof. 10. An apparatus for introducing an additive into a fluid stream comprising an additive pod comprising at least one sidewall defining an additive holding chamber and at least one depressible engagement tab extending from the at least one sidewall that is flared at an angle to a longitudinal axis of the additive pod, the engagement tab having a distal portion configured to cooperatively engage with at least one receiving member on an outlet portion of a fluid handling apparatus, wherein at least a portion of the at least one sidewall is porous;at least one additive disposed in the additive holding chamber, wherein the additive holding chamber is configured to disperse the additive into the fluid stream and wherein the additive holding chamber is configured to be disposed in an outlet portion of a fluid handling apparatus;wherein the additive pod further comprises:at least one upstream sealing member configured to form a seal with the outlet portion of the fluid handling apparatus;at least one downstream sealing member configured to form a seal with a downstream article. 11. The apparatus of claim 10 further comprising at least one additive retaining member configured to retain the additive within the additive holding chamber prior to dispersion of the additive into the fluid stream. 12. The apparatus of claim 10 further comprising a storage container comprising at least one sidewall defining an enclosed volume, wherein the additive pod is hermetically sealed within the enclosed volume. 13. The apparatus of claim 10 wherein the additive comprises a sanitizer selected from the group consisting of chlorine, chlorine dioxide, iodine, hypoiodous acid, bromine, hypobromous acid, hypochlorous acid, fluorine, alcohol, hydrogen peroxide, ozone, and combinations thereof. 14. A system for introducing an additive into a fluid stream comprising a filter cartridge having a housing and an outlet portion, wherein an outlet flow stream exits the housing through the outlet portion;an additive pod comprising at least one sidewall defining an additive holding chamber and at least one depressible engagement tab extending from the at least one sidewall that is flared at an angle to a longitudinal axis of the additive pod, the engagement tab having a distal portion configured to cooperatively engage with at least one receiving member on an outlet portion of a fluid handing apparatus,wherein the additive pod has a first at least partially open axial end, a second at least partially open axial end, and the sidewall is a closed wall extending between the first at least partially open axial end and the second partially open axial end that allows fluid to flow into the additive pod along its longitudinal axis and allows fluid to exit the additive pod along its longitudinal axis;at least one additive disposed in the additive holding chamber, wherein the additive holding chamber is configured to disperse the additive into the fluid stream;wherein the additive holding chamber is configured to be disposed in the outlet portion of the filter cartridge. 15. The system of claim 14 wherein the outlet portion further comprises at least one release member configured to cooperate with the additive pod to facilitate disengagement of the additive pod from the outlet portion. 16. The system of claim 14 further comprising a storage container comprising at least one sidewall defining an enclosed volume, wherein the additive pod is disposed within the enclosed volume. 17. The system of claim 14 wherein the additive holding chamber is disposed in the outlet portion of the filter cartridge.
