Filter apparatus for filtering liquids comprising a hollow filter body (12) mounted in a housing (18) having an inlet port (22) for supplying liquid to be filtered to the interior of the housing. An outlet port (24) for filtered liquid communicates with the interior of the filter body. A motor (16) is arranged to rotate the filter body around a vertical axis and paddles on the filter body cause liquid to be filtered to flow in a direction around the axis. In operation, at least some of the matter, such as particulate matter held in suspension or carried by the liquid which is heavier than the liquid, is caused to be directed outwardly in a direction from said filter body towards said housing. This matter would also be downwardly directed towards the bottom of the housing.
