Abstract
The invention relates to a water tank (1) and a water filter cartridge (2) where the water filter cartridge (2) has two different water filter cartridge outlets connected to two different filter treatment sections in a single filter cartridge housing to provide for the different treatment of water received from a common inlet. More particularly, the new filter can treat hot water separately from cold water and discharge the separately treated water from the which can be arranged concentrically to one another.
