ABSTRACT:
A wash basin drain filter for entrapping elongated flexible fibers such as hair while permitting the passage of relatively small particulate matter is disclosed herein. The filter has a generally cylindrical body which, after installation, about the shank of a pop-up drain plug has a plurality of spikes protruding outwardly therefrom. The spikes are resilient to permit insertion of the filter into the drain opening and, after insertion, the spikes extend to touch or nearly touch the inside wall of the drain pipe into which the filter has been inserted.
