Abstract: This invention is a selective drain hair filter, which allows debris to bypass the filter. The invention contains a circular disk with a centrally positioned hole that sits around a drain flange, held in place by the larger diameter posts and the pressure of flowing water over the circular disk with central hole and sloped base. Water flows around posts of varying heights and diameters and a circular wall with cutout channels. Hair flowing around the posts gets twisted into rotation by the upwardly sloped base and by hitting the wall structure and posts next to the channels. This device selectively filters hair to prevent unsightly debris build up found on other devices. It contains no discrete filtration apertures for hair and debris to get stuck within, allowing easier cleaning. The simpler and low-profile design is more aesthetically pleasing and less prone to encouraging mold growth.
