Abstract: A microplastic filter (also referred herein as fluid filter) for a washing machine has a filter housing, a first filter screen, a second filter screen, an inlet opening 16, and an outlet opening. The inlet and outlet openings communicate with each other through the first filter screen to define a direction of fluid flow. The first filter chamber has a retentate outlet, is particularly easy to handle if the second filter screen is arranged in a cavity of the filter housing, the inlet and outlet openings communicate with each other through the second filter screen, and the retentate outlet is arranged on a side of the second filter screen that faces the fluid flow.

Abstract: A liquid recovery filter assembly for recovering filtered liquid trapped within a core or downstream side of a filter element. Multiple embodiments each include a recovery port and a recovery filter in fluid communication with the core or downstream side of the filter element. The recovery port is opened following filtration operations to permit and to facilitate filtered liquid to flow from a downstream or outlet port, thus allowing recovery of liquid remaining in the filter core or downstream side following filtering operations. The recovery filter permits the introduction of pressurized gas to force the filtered liquids from the filter assembly without compromising the sterility and/or non-contaminant condition of the liquid. Additional aspects include exchangeable filter cartridges or filter elements in single and multi-round configurations, embodiments with aspiration tubes and dip tubes and still others with hydrophilic/hydrophobic recovery filters that function as filters and as valves for the recovery port.

Abstract: Aspects herein include filter systems including short-range wireless tracking features to detect insertion and/or removal of filter elements from filter systems. In an embodiment, a filtration system is included having a housing including a fluid inlet and a fluid outlet. The housing can define an internal volume. A first filter element can be removably disposed within the housing. A short-range wireless communication tag can be associated with the first filter element. A short-range wireless communication reader can be associated with the housing, the reader configured to wirelessly send data to and receive data from the tag when the reader and the tag are at a distance that is less than or equal to a maximum communication distance. Removal of the first filter element from the housing can cause the distance between the tag and the reader to exceed the maximum communication distance. Other embodiments are also included herein.

Abstract: A gravity-fed filtration apparatus includes a filter housing having a water inlet near an upper portion of the filter housing and a water outlet near a lower portion of the filter housing. A water filter having a plurality of discs is removably stacked within an interior cavity of the filter housing between the water inlet and the water outlet. An outer perimeter portion of each of the plurality of discs sealingly engages with an inner surface of the filter housing. A first disc of the plurality of discs comprises a first plurality of diffusers and a disinfectant media. A second disc of the plurality of discs comprises a mesh. The lower portion of the filter housing is configured to be disposed in the mouth of a water vessel.

Abstract: A fuel injector filter is disclosed. The filter may include an inner ring concentrically surrounded by an outer ring. The inner ring may radially extend between an inner ring inner perimeter and an inner ring outer perimeter, and comprise a first port radially extending between the inner ring inner perimeter and the inner ring outer perimeter. The outer ring may radially extend between an outer ring inner perimeter and an outer ring outer perimeter, and comprise a first aperture radially extending between the outer ring inner perimeter and the outer ring inner perimeter. The first aperture may be circumferentially offset from the first port. A filtration channel may radially extend between the inner ring outer perimeter and the outer ring inner perimeter and be configured to impede movement of a particle toward the first port.

Abstract: A filter (10) with a filter element (36) are described. A housing (12) includes at least one fuel inlet, fuel outlet (18) and a water outlet (30) for water separated from the fuel. The filter element (36) within the housing separates the fuel inlet (26) from the fuel outlet (18). The filter element (36) includes a hollow body filter medium (38) flowed through radially. A water separation unit (56) with a hollow body hydrophobic fuel-permeable separating medium (66) separates water contained in the fuel and includes at least one support structure disposed in the flow path (78) in such a way that a precipitation gap (74) is realized between the filter medium (38) and the separating medium (66). The precipitation gap (74) is connected with the water outlet (30).

Abstract: A “no filter, no run” filtration system that is designed to verify that a filter cartridge is present to safe-guard against damage to fuel injectors, associated fuel components, etc. and engine malfunctions. Fuel flow to the engine is prevented altogether or permitted in an amount insufficient to allow engine operation if a filter cartridge is not installed, and an appropriately designed filter cartridge is required to be used in order to permit sufficient fuel flow for engine operation. In one embodiment, a flow restriction valve is provided that includes a ball.
