Abstract

An apparatus for the treatment of water. A water filter is mated with a housing base and cover to form an integral unit to treat water. A valve connected to a water faucet diverts the flow of water from the tap through a filter inlet tube, through the filter and back to the valve via a filter discharge tube. A second position on the valve permits the water flow from the faucet to by-pass the treatment filter. The replaceable filter has indicator means to visually indicate whether or not satisfactory flow is being maintained through the unit and whether or not the filter should be changed.
