Embodiments of a multi-purpose shower/tub filter unit are shown and described, the filter unit containing a chlorine-removal media and a scale-inhibiting media. The housing of the filter unit is adapted to attach universally to various water sources, such as a pipe or faucet and to a showerhead or hand-held spray unit. The filter unit preferably has an arm extending out from the main body of the filter unit, and the filter unit preferably extends upward and outward from the attachment point on the pipe or faucet. This way, a single filter unit may either be positioned a) substantially above a shower pipe to place the showerhead generally at a similar level as it would be without the filter unit in place, as in a United States shower configuration; or b) to fit under but extend out from a tub faucet, as in a European shower configuration. The filter unit has a replaceable cartridge that includes a carbon block and scale-deposit-inhibiting phosphate spheres contained in a space inside the carbon block. The filter unit housing is designed to be opened by hand for easy replacement of the filter cartridge and to have seals between two portions of the housing and between the filter cartridge and the housing which are held securely in place and are, therefore, not prone to damage during cartridge change-out. The filter cartridge is designed to be symmetrical and bi-directional, in that it can be inserted into the filter housing with either end in an upward orientation, to make installation trouble-free. Connections to plumbing, showerheads, and hand-held sprayers may be adapted to a wide variety of baths/shower around the world, by threading changes or by couplers or showerheads designed for particular configurations.
