A filter cartridge assembly intended for replaceable installation in a demountable cartridge housing includes in one embodiment, a retaining ring (30) that is attached to the product water tube (20) of the filter cartridge (11), is inserted with the cartridge into the housing, and is locked to the housing such that, upon subsequent removal of the housing to change the cartridge, the cartridge will be forced from sealing engagement with the end cap header and caused to remain in the housing until the housing has been removed.

Brine ring embodiments (31, 110, 120) that are welded to the housing or attached to the housing with a snap-in connection are also disclosed.
