In a multiunit filter apparatus for removing solid particulate matter from a flowing fluid, automatic cleaning of the filter units is effected without employing valves and without interrupting the flow of fluid to be filtered, by connecting the filter units in parallel between a common inlet and outlet and forming the inlet as a multistable diverter of the coanda-type which periodically switches the incoming fluid from one filter unit to another and creates a reverse flow of fluid through a filter unit from which the incoming flow has been temporarily switched.
