Liquid filtration by means of a flow-through filter unit. An open-top housing is adapted to contain a removable filter cartridge having a center bore. Closing the housing with its cover effectively centers the cartridge and also seals both ends of the cartridge to keep unfiltered liquid from bypassing it. A concave baffle below the cartridge reorients the inflow of unfiltered liquid and defines a compartment from which the liquid flows to and enters both ends of the cartridge, flows therein and is filtered, flows radially to the center bore, and axially therefrom to an outlet for filtered liquid.

Method of liquid filtration, comprising the steps of passing liquid via an off-axial inlet opening into a generally cylindrical housing having an open end provided with a removable cover and adapted to receive an axially bored replaceable filter cartridge coaxially about an axial outflow pipe extending from within the cartridge bore to an outlet opening from the housing, sealing opposite ends of the cartridge to the cover and the axial pipe respectively by means of coaxial cylindrical edges pressed thereinto outside the cartridge axial bore upon closing the housing by the cover, and enabling the liquid to flow from the inlet to and mainly axially through the filter cartridge, then radially to the outflow pipe, and axially therethrough to and out from the outlet opening.
