Water to be purified contained in a reservoir (4) passes through a filter cartridge (3) to a receptacle (1). The water enters the cartridge through slots (14), travels downwards round a baffle (11), then upwards between the baffle and a wall (12) to be discharged through slots (16). The purified water is eliminated between the cartridge and a wall of reservoir recess (8). Flow is controlled by hood (18) manually positioned by screw (21) when rod (22) is turned. A manually actuated unidiriectional indicator rotor can monitor the number of operations. Reservoir (4) rests on a stand (2, 6) from which the receptacle can easily be removed but the reservoir can also rest directly on the receptacle, located by rib (36). |
