Abstract: A multi-stage drain filter insert (10) comprises a first basket (14) installed in a drain (D) inlet (I). A second basket (20) fits inside the first basket and is installed therewith for debris in the water flowing into the insert to be collected in a bottom of the second basket. An absorption media in a pouch (26) installed in the second basket for removes hydrocarbons from water flowing into the drain through the insert. A filtration media in a pillow (24) installed in the first basket between the first and second baskets removes contaminants, including bacteria, from water flowing through the second basket into the first basket. As a result, debris and contaminants are substantially removed from water flowing from the insert into the drain.
