A filter assembly includes a filter head and a filter cartridge. The filter head includes a filter head coupling surface, a filter head outlet, a filter head inner wall, and a filter head outer wall. The filter head coupling surface defines a filter head opening. The filter head outlet is configured to provide a fluid. The filter head inner wall extends around the filter head outlet. The filter head outer wall extends around the filter head inner wall. The filter head inner wall and the filter head outer wall collectively define a filter head channel. The filter cartridge includes a filter cartridge shell and a filter element. The filter cartridge shell has a filter cartridge coupling surface that is configured to be coupled to the filter head coupling surface. The filter cartridge shell defines a filter cartridge opening.

To move a filter along a manifold assembly the filter may be seated on a moveable shuttle assembly. Seating the filter on the shuttle assembly may include mating a key portion on the filter with a key portion on the shuttle assembly, each key portion corresponding to a filtration characteristic of the filter. The shuttle assembly and the seated filter may then be moved between a first position, wherein the key portions of the filter and the shuttle assembly are mated to one another and first and second fittings of the filter are spaced from first and second fittings of the manifold assembly, and a second position, wherein the key portions of the filter and the shuttle assembly are mated to one another and the first and second fittings of the filter sealingly engage the first and second fittings of the manifold assembly.

A liquid filter for a motor vehicle may include a hollow cylindrical housing bowl, a cover that closes the housing bowl, a suspended, hollow cylindrical particle filter arranged in the housing bowl, a catch basin that is opened towards the cover, and an edge overflow. The particle filter may extend parallel to a longitudinal center axis of the housing bowl and may divide the housing bowl into a clean liquid chamber and into a raw liquid chamber. The raw liquid chamber may be fluidically connected to at least one inlet arranged in the cover and the clean liquid chamber to at least one outlet arranged in the cover.

A completely biodegradable cartridge for a water filter that can replace traditional non-biodegradable cartridges. The cartridge may also include one or two caps also made from biodegradable material.

A disposable dental waste filter device has a body having a receiving end, and a separable cap having a tip end, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap. A disposable dental waste filter device also has a body having a receiving end, a central lumen for receiving and capturing amalgam, a filter, and a circular leg portion having an exterior channel, and a separable cap having a tip end, a circular outer rim having a circular end ridge portion with the ridge portion adapted to be inserted into the exterior channel of the body for a snap fit engagement between the cap and the body, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap.

A disposable oil filter containment sheath is provided for use during oil changes for combustion engines. The sheath has a closed bottom, a cylindrical sidewall, and an open top. The resilient sheath is rolled to an initial collapsed position for placement on the bottom of an oil filter mounted on the engine, and it is partially unrolled along the filter. The filter can then be loosened to allow oil to drain into the sheath for capturing a reservoir. After the filter is removed from the engine, the sheath is completely unrolled and tied at the top so as to fully enclose and contain the oil filter and oil. The sheath and its contents are then ready for disposal.
