ABSTRACT A disposable filter unit for use with a parts washer or the like. The filter consists of a body in the general form of a bag, made from a softenable but substantially solvent-impermeable thermoplastic material having a neck portion attached to a mount- ing collar. The mounting collar is a stiff but resilient element suitable for being positioned and retained within the drain opening of the parts washer, being constantly held in place by a cup or screen. The filter body has large by-pass openings in the neck, smaller openings in the upper body portion and still smaller openings in the lowermost portion. The filter acts by trapping sharp-edged or jagged particles such as slivers and filings, both on the interior surface of the bag and within the openings. Entrapment of the filtered material effectively creates a finer mesh filter, and the graduated opening sizes provide a combination filtration and settling action.
