A unit cartridge with a support ring gasket, and upper debris sweep, and debris retention bin is presented for use in filtering storm water runoff. Unlike some other configurations of cartridges, which rest the bottom of the cartridge on a support grate and ring, the present configuration rests on a support ring formed or built to the top of the cartridge. A debris bin is formed above and as part of the unit cartridges to capture sediment which would otherwise lie on top of the cartridges or filter baskets to prevent or impede removal. At the top of the cartridge is a debris sweep to remove adhering debris to allow easier installation and removal of the cartridge. Below the support ring may be formed or placed a gasket to prevent further debris or water bypass when the cartridge is seated. The cartridge is adapted to existing or new storm water or water infiltration wells which have been adapted to receive and support the cartridge filter. The cartridge can be fit into conventional storm water infiltration wells that are pre adapted to receive filters.
