A container (30) for housing a beneficial agent (66) that can be removably coupled to a structure (12) defining a fluid flow path. The container (30) comprises a body (32) defining a first (56) and second (58) interior area separated by a wall (60) that terminates at an opening (62) providing fluid communication between the first (56) and second (58) interior area. A cannula (34) is provided that extends from the body (32) for being removably received by the structure (12) defining the fluid path. The cannula (34) including an inlet opening (44) and inlet fluid flow path (36) and an outlet opening (54) and outlet fluid flow path (37). The inlet fluid flow path (36) being in fluid communication with the first interior area (56), and the outlet fluid flow path (37) being in fluid communication with the second interior area (58). The second interior area (58) housing the solid beneficial agent (66) and allows fluid that flows through the inlet fluid flow path to pass by at least a portion of the beneficial agent (66).
