The invention provides a faucet-mounted water filter comprising an upright tubular diverter body that is adapted to be secured to the open end of the water faucet. At the bottom of the diverter body is a water outlet through which unfiltered water can be dispensed. In the diverter body is a valve with a valve outlet duct projecting from one side of the diverter body. A manually movable valve handle projects from the diverter body and is connected to the valve for directing the flow of water either through the water outlet (when unfiltered water is required) or for diverting water through the outlet duct. A filter housing is mounted upon the duct and is preferably connected to the diverter by means of the duct. A carbon block filter element is provided in the filter housing which includes a vertical water inlet surface on an outside wall and a water outlet at the bottom. The filter housing includes an annular water distribution chamber for unfiltered water which surrounds the filter element. The outlet duct of the valve is connected through the side of the filter housing at an elevation which communicates through the annular water distribution chamber with the water inlet surface of the filter element. The water outlet at the bottom of the filter element communicates with a dispensing opening for filtered water at the bottom of the filter housing. If desired, a paper prefilter is provided for filtering the water before it enters the carbon block filter.

A water faucet-mounted water filter for filtering impurities from water received from a water faucet, the water filter comprising: (a) a diverter including: an upright diverter body with a water inlet at a top end thereof, the water inlet having an internally threaded swivel collar constructed to be connected to the water faucet for receiving unfiltered water and a water outlet at a bottom end of the diverter body opposite the water inlet for dispensing unfiltered water from the diverter to a sink or other receptacle; a diverter outlet duct projecting from one side of the diverter body; and a valve in the diverter body, the valve being movable from a first position where the unfiltered water enters the water inlet and exits the water outlet to a second position where the unfiltered water enters the water inlet and exits the diverter outlet duct; (b) filter housing defining a filter chamber, the filter housing having: a cylindrical side wall; a top portion closed by a top wall integrally formed to the side wall; a bottom portion closed by a separately formed bottom wall; a boss extending from one of said walls of the filter housing and connecting the filter housing to the diverter outlet duct such that the filter housing is supported by the diverter body, the boss having an opening through the wall from which the boss extends and the diverter outlet duct being connected through the boss opening to the filter chamber; and a dispensing opening positioned on the bottom wall for dispensing filtered water from the filter housing into the sink or other receptacle; (c) a carbon block filter element positioned in the filter chamber such that the filter housing and the filter element are supported upon the diverter in close proximity to or in contact with the diverter, the filter element including a water inlet surface on a side wall thereof and a water outlet; an annular water distribution chamber surrounding the filter element, wherein the diverter outlet duct communicates through the annular water distribution chamber with the water inlet surface of the filter element, and wherein the water outlet of the filter element communicates with the dispensing opening of the filter housing such that the filtered water is dispensed from the filter housing.
