A filter assembly includes a filter element and a filter housing. The filter housing includes a shell defining an inner cavity, and a lid configured to engage the shell at an opening of the inner cavity. The filter element is disposed within the inner cavity and includes a media pack, a first endplate, and a sealing member. The first endplate is sealingly engaged with a media pack first end and includes a skirt extending along a longitudinal axis of the media pack from the first end toward the second end. The sealing member is coupled to the skirt and is positioned between and forms a seal between the lid and the shell.

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.

A submersible vacuum cleaner to clean artificial pools, such as swimming pools. A suction head connected to a suction duct leading into a filter bag. A motor coupled to an impeller located within the suction duct. The spinning of the impeller producing a suction. A battery powering the motor. The motor and the battery being placed in a watertight compartment, itself mostly placed within the filter bag, so as to obtain a compact design of the vacuum cleaner.

A composite media includes a stack with 20 or more layers, each layer including a substrate with a first major surface and an opposing second major surface; and a fiber layer deposited onto the first major surface of the substrate and including polymeric fibers with a diameter of 100 nm to 1.5 μm. Each fiber layer independently has a thickness of 5 μm to 100 μm, and each layer independently has a pore size of 0.1 μm to 10 μm. A filter may include a housing and the composite media disposed within the housing. The filter may be a syringe filter.

A water filtration housing containing a pressure vessel configured to receive a water filter cartridge; a ring enclosure attachable to an open, top end of the housing enclosure; an interface tower including a user interface; a lid assembly removably attachable to the ring enclosure, the lid assembly including (i) a pressure cap and gasket for maintaining a given pressure in said pressure vessel and (ii) a rotatable lever for disengaging the pressure cap from the pressure vessel thereby releasing pressure therein. A mating system between the lid assembly and ring enclosure prevents the lid assembly from being attached to the ring enclosure in a misaligned fashion. RFID technology may be used for identifying the water filter cartridge installed therein and wireless communication technology (e.g., Wi-Fi) to transmit collected system data (e.g., water usage) to a central location for analysis such that the customer is provided with, for example, operational suggestions.

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.
