A multi-functional water filtration apparatus includes an outer housing defining a receptacle for receiving a filter assembly and having an inlet port at a first end for intake of unfiltered water and being open at a second end. The filter assembly includes an endcap closing the second end of the outer housing and a filter element enclosed within the outer housing. The endcap has an outlet port for dispensing filtered water. The outer housing has a flow passageway extending between the inlet port and the outlet port. The filter element is disposed in the flow passageway and has an upstream side in fluid communication with the inlet port and a downstream side in fluid communication with the outlet port. In certain aspects, the filtration apparatus provides multiple attachment options. In further aspects, a method of filtering water is provided.

The filter for the purification of a liquid of a combustion engine, particularly lubricating oil, includes a housing that has, in a bottom part, an inlet for raw liquid and an outlet for purified liquid, and an unscrewable lid. A cartridge, defined by a filtering insert and a preassembled bypass valve, is received in the housing. The insert has a flange for fixing the valve, covering an end of the filtering medium. The bypass valve can be separated from the cover such that the cartridge can be removed. The valve has a removable connection element that axially engages with a complementary securing component formed on the flange, in a locking configuration obtained by a pivoting action.

The present invention discloses a filtering apparatus for filtering liquid and dispensing the filtered liquid into a bottle separate from the filtering apparatus. The filtering apparatus includes an elongated housing having an interior for holding liquid. The elongated housing includes an opening at one end and a ceiling at another end. The opening encompasses projections extending towards the center of the elongated housing. The filtering apparatus includes a filter configured for insertion and removal from the elongated housing. The elongated housing receives the filter at the interior through the opening. The elongated housing receives a bottle at the opening and the projections hold the bottle at the opening while preventing further entry of the bottle into the interior of the elongated housing. The interior holds liquid and allows the liquid to flow down through the filter. The filter filters the liquid as it flows through. The filtered water enters the bottle for subsequent use, storage or transport.

A filter assembly, comprising an open top housing comprising an inlet and an outlet; a filtering unit configured to be positioned within the housing, the filtering unit comprising a filter; a mounting arm connected to the d housing; and a fastener actuatable for extension from the mounting arm; wherein: iv) in a first position, the mounting arm is moved away from the open top of the housing; v) in a second position, the filtering unit is positioned within the housing, the mounting arm is positioned on top of the housing, and the mounting arm secures the filter within the housing; vi) in a third position, the filter is being positioned within the housing, the mounting arm is positioned on top of the housing and connected to the housing in fluid tightness, the mounting arm secures the filter in fluid tightness within the housing; and the inlet and the outlet of the housing are opened to a flow of fluid to be filtered through the filter.

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 rotary pressure filter suitable for use in treatment of one or more of medical products or foodstuffs, the rotary pressure filter. The rotary pressure filter comprises a filter drum that can be rotated about an axis of rotation. The rotary pressure filter comprises a plurality of filter cells arranged along an outer circumference of the filter drum, with a housing surrounding the filter drum. A process space is formed between the filter drum and the housing. The rotary pressure filter comprises at least one separating element dividing the process space into a plurality of treatment zones. At least one treatment zone is associated with a housing connector via which one or more of fluid or suspension can be introduced into the respective treatment zone.

An oil filter for a motor vehicle has a filter cartridge which is disposed in an oil filter housing of the oil filter. The filter cartridge has a channel for filtered oil which is surrounded at least regionally by a filter material in the radial direction. At least one through opening is formed in a wall of the channel. An emergence of filtered oil via the at least one through opening into a channel for the filtered oil provided on sides of the oil filter housing is preventable by bringing the filter cartridge into a first position. An inlet into the channel provided on sides of the oil filter housing fluidically connectable to the at least one through opening by bringing the filter cartridge into a second position in which the filter cartridge is shifted relative to the first position in an axial direction.

A spin-on filter assembly with replaceable coreless element comprises: a reusable spin-on housing including a filter bowl having sealing structure on a bottom of the filter bowl and a sealing structure on a top of the filter bowl; a center support tube integral with the filter bowl and including a perforated tube and an upper portion having an threaded coupling allowing for the filter assembly to threaded into position and an exterior sealing structure; and a replaceable coreless filter element mounted on the central support tube within the filter bowl and having filter media, a lower sealing structure configured to engage with the sealing structure on the bottom of the filter bowl and an upper sealing structure configured to engage with the exterior sealing structure on the center support tube.

The technology disclosed herein relates to, in part, a filter assembly having a primary media assembly and a secondary media assembly in fluid communication with the primary media assembly. A filter assembly outlet is downstream of the secondary media assembly. A filtration pathway extends through the primary media assembly, the secondary media assembly, and the filter assembly outlet. A drain pathway extends through the secondary media assembly and the filter assembly outlet, wherein the drain pathway circumvents the primary media assembly.

A water purifying apparatus including a head having a water inlet portion and a water outlet portion; a shaft provided in the head and rotatably mounted between the water inlet portion and the water outlet portion; a bypass flow path passing through a circumference of the shaft, and communicating the water inlet portion with the water outlet portion according to rotation of the shaft; a filter detachably mounted to the head, and having a filter inserting portion in which the shaft is inserted when being mounted on the head; and a filtering flow path in which an inlet port and an outlet port are formed on the circumference of the shaft in a direction intersecting the bypass flow path, and communicated between the filter, the water inlet portion and the water outlet portion with each other according to the rotation of the shaft.
