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.

Embodiments of a gravity filter for potable water comprise a loose filter bed comprising ion exchange resin particles and activated carbon particles, and a porous non-woven filter substrate disposed downstream of the loose filter bed, wherein the porous non-woven filter substrate comprises an impregnated heavy metal scavenger.

Systems and methods of eliminate filter air locks by maintaining a constant water table at the water head layer of the filter. The constant water table eliminates air locks in the filter as the filter drains. Water flows from the water head layer through a filtration medium in a filter cartridge, and the filtered water is output from a water outlet at the top of the cartridge. For a water table retention filter, where the water (or other liquid) being filtered, is re-directed to the top of the filter to the water head layer to avoid drawing air into the filter. Unfiltered water drains down the center of the filter to the water head layer and then flows up through the filter and is directed out near or at the top of the filter.

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.

A fluid filter for a motor vehicle includes a filter housing and a filter cartridge which is fixable on the filter housing by rotating around a longitudinal axis of the filter cartridge. A holding element having a web is disposed on an end plate of the filter cartridge where the web protrudes from a wall of the holding element and where the wall is formed as a spiral shape. The web of the holding element is engageable behind a holding web of a counter bearing disposed on the filter housing that is spiral shaped. The holding web has an incline in a rotational direction in comparison to an abutment region of the filter housing on which a sealing element of the filter cartridge abuts.
