Abstract
A flow-directing water filtration system provides a flow of water through a cylindrical filter cartridge that is more uniform by inclusion of multiple water-directing ridges that form channels between them between the inner wall of the housing and an outside wall of the water filter cartridge for directing laminar flow of water along the outside wall of the water filter cartridge to improve distribution of water flow through the water filter cartridge along its length. The ridges may be formed on the inner wall of the housing, may have a half-circular profile and may be helical ridges that spiral along the extent of the cartridge and may taper in profile toward the bottom of the cartridge.
