ABSTRACT:
Filter cartridge for the improvement of the quality of drinking water, consisting of a vessel (10) with sieve-type covered apertures (18, 44) filled with a compound (16) of ion exchange resin and/or absorbent carbon together with a bacterio-statically effective material, in particular silver, in dissociable form, through which the water to be treated is conducted mainly in a downwards direction, the vessel having a collection space (48), for a limited quantity of water, originating from the vessel's floor (42), which is separated from the outlet aperture (44). Thus drying out of the cartridge through non-use over a longer period of time or through misuse is prevented and the effectiveness of the bacterio-statically effective material is retained to combat the feared multiplication of germs in the treatment compound.
