A WATER FILTER UNIT

A water filter unit for purifying water fed to the water filter unit. The unit includes a containment defined by a wall section, first and second end sections, wherein the wall section is attached to the first end section and the second end section; a water inlet arranged in the first or second end section through which the water is fed into the containment; a filter membrane arranged in the containment such that at least part of the water is fed through the filter membrane; and a first water outlet for filtered water from the membrane. The unit further includes an injector pump arranged to create an increased flow velocity trough the injector pump of the water fed to the filter membrane, and the injector pump is furthermore arranged to receive unfiltered water not fed through the membrane and recirculate the unfiltered water within the containment.
