A cooking oil filtering apparatus has a frame and a filter supported therein. The filter is an assembly of juxtaposed layers including a filter layer formed of a uniformly porous web comprising randomly distributed, randomly interentangled, synthetic polymeric blown microfibers that are less than 10 microns in diameter and a support layer of highly porous, relatively stiff, light weight sheet material, more porous than the filter layer.

A cooking oil filtering apparatus especially suited for gravity filtration, said apparatus comprising a frame and a filter in the shape of a cone or a bag supported in said frame comprising an assembly of juxtaposed layers, as follows: (a) an inside filter layer formed of a uniformly porous web comprising uniformly distributed, randomly interentangled, synthetic polymeric, blown micro-fibers that are less than 10 microns in diameter, said web having a weight in the range of about 30 to 47 g/m2, a flow time to pass 200 ml of cooking oil of less than about 40 seconds, and a pressure drop of less than about 42 Pa, and (b) an outside support layer of a highly porous, relatively stiff, light weight sheet material, more porous than said filter layer wherein said layers are formed of materials which are resistant to thermal degradation and appreciable softening at normal cooking temperatures of said cooking oil and are disposed within said frame with said filter layer positioned to initially receive cooking oil passing through said layers.
