Abstract: A funnel for filtering particulate from a liquid with improved filtration flow rate using flow paths through a filtering interface defined by a filter element and orifices predominantly on the wall of a conical inner funnel member. Particulate accumulates at the vertex of the inner funnel member. Filtered liquid passes through a collecting chamber between the inner funnel member and an outer funnel member and discharges through a spout. Filtration through the funnel may be assisted by application of a vacuum suction on the filtered liquid side of the filter element or application of a positive pressure on the unfiltered liquid side of the filter element. The inner and outer funnel members can be easily disassembled for cleaning.
