A method of filtering hot cooking oil including passing the oil through a screen to remove particulate matter and then pumping the oil under a relatively low positive pressure through a filter pad of uniform thickness and porosity composed in part of fibrous material and possibly other elements such as activated carbon and silica bound by a resin binder. Equipment for filtering cooking oil including a reservoir for storing strained oil, pump means for drawing oil from the reservoir and passing it under relatively low pressure through a filter pad of uniform thickness and porosity composed at least of fibrous material and possibly other elements such as activated carbon and silica bound by a resin binder and sealed in the base of a pressure chamber.
