Title: Apparatus for altering the characteristics of a fluid

Abstract: An apparatus for altering characteristics of a fluid. The apparatus includes a canister having a side wall, a first end wall, and a second end wall defining a chamber therein. A beneficial agent is disposed in the chamber. The end walls define apertures therethrough. The apparatus further includes a tubing portion defining a first end portion constructed for connection to a fluid source and an outlet portion. The tubing portion also defines a canister-receiving portion intermediate the first end portion and the outlet portion. The canister-receiving portion defines a first fluid flow channel fluidly connecting the first end portion and the second outlet portion of said tubing portion. The canister-receiving portion also defines first and second fluid flow orifices therethrough. The canister-receiving portion is constructed to be selectively connectable to the canister such that fluid from the tubing portion can be selectively directed through the canister chamber, thereby causing the beneficial agent to become dispersed in the flowing fluid.
