An automatic backflow washing-type filter comprising a primary filtering unit a substantial area portion of which is employed to primarily filter a charge of oil to be filtered, a filtrate accumulation unit for accumlating and supplying a substantial portion of the filtrate from said primary filtering unit to a consuming device and for recycling the remaining minor portion of the filtrate as a backflow washing filtrate. This washing filtrate washes the primary unit to remove foreign matter deposited on the primary filtering unit. In addition, the device includes a secondary filtering unit for filtering said backflow washing filtrate containing foreign matter after the washing of the primary filtering unit, the secondary filtering unit also being washed while filtering the backflow washing filtrate from the washing operation on the primary filtering unit.
