A water filter unit

A water filter unit (100) for purifying pressurized water fed to the water filter unit (100) is provided, said water filter unit (100) comprising; a containment (101) defined by a wall section (110), a first end section (111) and a second end section (112), wherein the wall section (110) is attached to the first end section (111) and the second end section (112); a water inlet (120) arranged in said first or second end section (111,112) through which the pressurized water is fed into the containment (101); a filter membrane (130) arranged in said containment such that at least part of the water is fed through the filter membrane (130); a first water outlet (140) for filtered water from the membrane; wherein the water filter unit (100) further comprises an injector pump (150) arranged to create an increased flow velocity trough the injector pump (150) of said pressurized water fed to the filter membrane (130), and said injector pump (150) is furthermore arranged to receive unfiltered water not fed through the membrane and recirculate said unfiltered water within the containment (101).
