Doulton Imperial Sterasyl OBE W9220406 is a 10" x 3" replacement cartridge, microfilter with a high level of efficiency in removing fine particulate matter, bacteria, cysts, and turbidity. These OBE(open on both ends) cartridges are designed to fit industry-standard 10-inch filter housings for countertop and under sink systems.

Imperial Sterasyl is a highly efficient ceramic micro filter that provides genuine sub-micron filtration of drinking water. Sterasyl is manufactured with the highly consistent and controlled pore structure necessary to remove a wide range of water-borne contaminants over the life of the cartridge. The ceramic shell is infused with silver which serves as a disinfectant and inhibits the growth of bacteria and gives each cartridge enhanced bacteriostatic and self-sterilizing properties.
