A recharge and filter assembly includes a housing with a removable recharge and filter cartridge. The housing includes a canister with a removable cover allowing access to the cartridge. The cartridge includes a filter element comprising a ring of media and upper and lower end caps. The upper end cap carries a peripheral seal which provides a fluid-tight seal with the housing canister. An annular channel is provided between an annular portion of the upper end cap and the seal. An annular support member from the cover is received in the annular channel to support the upper end cap. Latching fingers on the upper end cap and a mating ring on the cover removably couple the cartridge to the cover. The cartridge further includes a recharge canister supported by tabs on the upper and lower end caps. Fluid is recharged by inhibitor material, while particulates and other contaminants are removed by the filter media.

1. A recharge and filter cartridge, comprising:a ring of filter media having a first end, a second end, and circumscribing a central cavity, a cylindrical weir inwardly bounding and extending along at least a portion of the length of the media, and a flow passage along the length of the media allowing fluid flow between the media and the central cavity internally of the weir; a first end cap fixed to the first end of the media ring and a second end cap fixed to the second end of the media ring; and a recharge canister supported in the central cavity of the ring of filter media between said first and second end caps, and a flow path between the recharge canister and the weir, a first seal for sealing the recharge canister around its periphery to the weir at an axial location along the canister such that fluid passing radially through the filter ring and through the flow passage is directed against one end of the recharge canister, the recharge canister including a flow opening through an annular sidewall of the canister to allow fluid to pass from the one end of the recharge canister into the flow path between the recharge canister body and the weir, the flow path extending to an outlet opening in the second end cap.
