A water filter for use in connection with a replaceable cartridge is disclosed. The cartridge filter has four stages, and a housing for the cartridge filter has a base in which the cartridge filter is mounted on a water-flow-control section extending from the base. The water-flow-control section includes a linearly slidable plunger that directs water either toward or away from the cartridge filter by means of a rotatable lever connected to a slot in the plunger.
