The present invention provides a disposable drain filter comprising a central shaft having a first end region and second end region, and a plurality of snaring discs having a central opening to accommodate the shaft. The snaring discs having radially emanating fins that form a fin snaring disc, wherein each fin is defined by a flat upper wall and a pair of side wall surfaces that meet at a single point, the flat upper wall having a plurality of upwardly projecting protrusions placed at the junction of the upper wall and side walls, to further grip materials. The fin has a narrow first end region affixed to the hollow tube, and a wide second end region. The second end regions of adjacent fins are separated by a 0.25 inch gap. A barb snaring disc is placed sequentially after each fin snaring disc, thereby forming an alternating sequence of snaring discs, wherein the barb snaring discs have radially emanating bristle extensions with barbs to further grip materials. The filter is dimensioned to take a resting position above the trap region of a shower drain. The filter can also be applied to a kitchen and lavatory drain.
