Abstract
The invention provides a water filter, particularly suited for household use, with valving (22) which enables either a bypass mode or a filtering mode. During the filtering mode the water flows through a number of filtering layers (8,12) one of which is a microporous membrane (12) and during the bypass mode the water flows parallel to and against the membrane (12) so as to cleanse the membrane (12) of material accumulated thereon during the filtering mode.
