Gravity filter designs configured for increased residence time
Embodiments of water filters comprise a filter housing configured to be disposed in a pour tray of a water filter pitcher, wherein a filter media cartridge is disposed inside the filter housing. The filter housing includes a housing floor, housing sidewalls extending upwardly, away from the housing floor, and at least one filter housing outlet disposed in one or more of the housing floor or the housing sidewalls. The filter media cartridge includes filter media, where the filter media cartridge comprises a cartridge floor spaced above the housing floor, cartridge sidewalls extending upwardly, away from the cartridge floor, and at least one filter media cartridge outlet disposed along one or more of the cartridge floor or the cartridge sidewalls. The water filter pitcher further includes a riser extending upwardly, away from the housing floor, and spaced between the housing sidewalls and the cartridge sidewalls, where the riser extends a distance above the cartridge floor. The riser forms a conduit volume.

Method and device for removing particles from waste water
A filter system configured to remove microfibers released from textiles being processed in a fluid. This fluid is sent into a filter housing containing a filter cartridge which in turn contains a movable inner filter. The movable inner filter is sufficiently flexible as to permit random movement in the fluid so that the inner filter rubs against the cartridge housing thereby removing particulate matter from the cartridge housing, thereby extending the useful life of the filter cartridge.
Customizable multi-stage water treatment system
A customizable multi-stage fluid treatment assembly typically includes a connector, a plurality of cartridges, and a cap. The plurality of cartridges have a treatment medium spaced within an interior volume of the individual cartridges, between the ends thereof. The ends of the plurality of cartridges are configured to receive a fluid, bring the fluid into operative contact with the treatment medium, and dispense the fluid from the opposing end of the cartridge. The connector is coupled with one end of the plurality of cartridges and has an inlet and an outlet for receiving and dispensing the fluid to and from an appliance. The cap is coupled with the other end of the plurality of cartridges, enclosing the fluid treatment assembly, which is configured to be received in a cavity of an appliance. The cartridges of the plurality of cartridges may be individually replaced with cartridges to meet customized needs.

TURBINE ENGINE LUBRICATION SYSTEM WITH WASH FLOW FILTER
An assembly is provided for a turbine engine. This turbine engine assembly includes a turbine engine component and a lubrication system. The lubrication system directs lubricant through the turbine engine component. The lubrication system includes a wash flow filter.
Filter element and fluid filter with radial vent hole
A filter element for filtering a fluid is provided with a first end disc and a second end disc. An annularly arranged filter medium is held between the first and second end discs. The filter medium can be flowed through by a fluid to be filtered in a radial direction relative to a longitudinal axis of the filter element from an exterior of the filter element to an interior of the filter element. A fluid outlet socket is connected to the filter medium and extends away from the filter medium in an axial direction past the first end disc. The fluid outlet socket is provided with a wall and at least one vent hole extending through the wall in the radial direction. A fluid filter is provided with a filter housing and with the afore described filter element that is arranged in the filter housing.
Fluid filtration apparatus and method
An apparatus and method for filtering a liquid utilize a filter apparatus including a bypass filter, a full flow filter, and a flow balancing element for dividing a total inlet flow of fluid to the filter apparatus into a bypass portion, passing through the bypass filter, and a full flow portion, passing through the full flow filter. The bypass filter has a lower filtering efficiency than the full flow filter element, so that a venturi tube is not required for causing the bypass portion to pass through the bypass filter. The flow balancing element divides the flow into a desired bypass portion and a desired full flow portion, at a predetermined operating temperature. Below the operating temperature, the bypass portion increases and the full flow portion decreases, the bypass portion becoming greater than the full flow portion at a second predetermined temperature below the operating temperature.
FILTER AND METHOD FOR FILTERING A LIQUID
An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an oil input port. A mounting plate is fixed with an outer enclosure. The mounting plate is further adapted to conduct oil from the machine into a peripheral portion of the outer enclosure, and then returning oil from a central portion of the outer enclosure back to the machine. Oil may pass from the peripheral portion to the central portion through a primary filter having a first porosity. A pressure-actuated valve is fixed fluidly between the portions of the outer enclosure.
LIQUID DISPENSER SYSTEM
A wall mounted filtering system includes a chassis having an outwardly facing planer surface, a central recess bay and at least one of an upper recess bay and a lower recess bay. The system includes a face plate covering at least a portion of the outwardly facing planer surface and a filter assembly including at least a first stage filter oriented horizontally within the at least one bays and attached to the chassis via a first hinge, the first stage filter being operably coupled to the chassis with the first hinge and second hinge to tilt outward between an initial filter position in which the first stage filter is located within at least one of the upper recess bay and the lower recess bay below the outwardly facing planer surface, and a final filter position in which the first stage filter extends outward from the outwardly facing planer surface.
