Claim:
A disposable drain filter comprising: a central shaft having a height, a first end region, a second end region and two looped handles formed at the first end region and the second end region, respectively; wherein said looped handles permit insertion and removal of the disposable drain filter from a vertical drain pipe of a kitchen sink or a lavatory from either end regions; a plurality of snaring discs defined by extensions emanating radially along the height of the central shaft, wherein each extension is spaced to form a gap along a latitudinal axis and longitudinal axis of the shaft to form a continuous helix along the height of the central shaft from the first end region to the second end region, wherein the gap between each extension is uniform; a railing, wherein the railing spirals around the plurality of snaring discs and stabilizes the helix, wherein extensions protrude through the railing and are dimensioned to form a gap between the snaring discs and an inner surface of the vertical drain pipe; two support arms extend generally perpendicularly from distal ends of the railing, the support arms connecting the railing to the first and second end regions of the shaft thereby stabilizing the railing; and wherein the railing is made of a flexible material to enable insertion from the vertical drain pipe of the kitchen sink or a lavatory through a trap region.
