Apparatus for water purification and used in drinking water supply systems and individual filters. The apparatus allows an increase in quality of the water purification by means of a helical arrangement of a granular filter and an increase of the number of passages in which the water is purified. A household filter comprises a housing with distribution grids at the water inlet and outlet, two and more helical partitions having the form of a flat band or rod twisted around the longitudinal axis and having three or more beam profiles, and, optionally, comprise one or more flat partitions dividing the water inlet and outlet.
