A water purification system for purifying water flowing through a water flow path. The system includes a water purification device having an inlet and an outlet in the water flow path and at least one interior volume communicating with the inlet and outlet. A purification medium is disposed within the interior volume of the water purification device. A flow control system is provided controlling a volume of purified water dispensed from the outlet. The flow control system includes an input device configured to allow a user to input a desired volume of purified water to be dispensed from the outlet and a sensing device coupled with the electronic input device and operative to determine the volume of purified water being dispensed from the outlet. A flow regulation device is coupled with the flow control system and operative to stop the discharge of purified water at the outlet upon reaching the desired volume of purified water.

Water purification system and method including dispensed volume sensing and control

A filter assembly for a water purifying apparatus including a plurality of cartridges. Each cartridge includes first and second ends and an interior volume containing a filtering medium. A plurality of end caps are respectively connected with the first ends of the plurality of cartridges and each end cap includes a water inlet and a water outlet. A removable manifold is coupled with the water inlets and water outlets and the manifold includes a pair of auxiliary ports. One auxiliary port directs water from the cartridge assembly to an auxiliary processing device and another auxiliary port directs the water from the auxiliary processing device back to the filter assembly. The water inlets and water outlets extend generally parallel to a longitudinal axis of each cartridge. The cartridge includes an outer tubular member in fluid communication with the water inlet and an inner tubular member in fluid communication with the water outlet. The inner tubular member has a first end connected in a sliding manner to the first end cap and a second end rigidly affixed to the second end cap.
