A single-use filtration device (10) comprises a plurality of single-use filter capsules (12) connected with each other by rigid lines, of which at least a part is firmly mounted in a raster universally specified by a holder (14). The filter capsules (12), in particular as regards the type of filter, type of construction and/or size, and/or the connections of the filter capsules (12), are preconfigured for a desired filtration process.

A fluid filter element for circular locking engagement with a filter support, the fluid filter element including a filter medium arranged about a longitudinal axis, first and second end caps arranged at opposite cylindrical ends of the filter medium and sealed thereto, at least one locking protrusion located on the second end cap for rotatably locking the fluid filter to the filter support and at least one releasable retainer located on the second end cap and associated with at the at least one locking protrusion for retaining the at least one locking protrusion in locking engagement with the filter support and being operative, when released, to allow rotatable unlocking of the fluid filter element.

A separator device for removing particles from suspension in a fluid includes first and second fluid-carrying portions and a non-fluid-carrying spacer for linking the first and second fluid-carrying portions. Each of the fluid-carrying portions includes a socket for receiving an open end of a pipe and a connector for connection of the filter. The socket of the first fluid-carrying portion has a pipe receiving depth greater than that of the socket of the second fluid-carrying portion. The sockets of the first and second fluid-carrying portions are positioned on a common axis and facing away from each other when the fluid-carrying portions are linked by the spacer.

A disposable filter capsule for a filtration device comprises only one housing, which has an inflow connection for a fluid to be filtered and an outflow connection for filtrate. The disposable filter capsule also comprises at least two separate filter means, which are fixed in the housing and together with the housing form an inseparable structural unit. All the components of the disposable filter capsule consist of sterilizable, in particular gamma-sterilizable, materials.

A water filter assembly includes a filter cartridge, a Wi-Fi module, and a valve attached to a water filter housing. The water filter housing includes a base portion with a number of retention tab receivers that engage retention tabs that are inserted into retention tab openings in an exterior surface of the refrigerator.

A fixing device is adapted for installing on a water filter which includes a base seat and an outer shell. The fixing device includes first and second curved members adapted to be clipped on a junction between the base seat and the outer shell, and a fixing module. The fixing module includes a hook member and a fastener unit that includes a handle member and a ring member which is removably engaged with the hook member. The handle member is pivotable between a fastened position and a released position, where the ring member is permitted to be disengaged from the hook member to release the first and second curved members from the junction between the base seat and the outer shell. A water filter including the fixing device is also provided.

A filter base for receiving a mating filter housing assembly having a base platform having fluid ingress and egress stanchions, and a wire harness assembly including a connector housing integral with or connected to the base platform for establishing an electrical connection between the filter base and the mating filter housing assembly. The wire harness assembly having conductors extending between first and second connectors, with one or more resilient contacts provided on the second connector. The contacts are flexible from a first position to a second position when curved contact sections of the one or more contacts engage a mating connection surface of the complementary mating filter housing assembly. The mating connection surface may be a circuit pad of a printed circuit board, wherein the contact curved contact sections are configured to be positioned in mechanical and electrical engagement with the circuit pads when the filter housing assembly is received within the filter base.

A filter base for receiving a complementary mating filter housing assembly. The filter base includes a base platform having fluid ingress and egress stanchions, and a wire harness assembly including a connector housing integral with or connected to the base platform for establishing an electrical connection between the filter base and the filter housing assembly. The wire harness assembly includes conductors extending between first and second connectors, with one or more resilient contacts provided on the second connector. The connector housing has an upper surface and an oppositely facing lower surface and is dimensioned to receive a first end portion of the one or more contacts. The contacts are flexible from a first position to a second position when a mating portion of the one or more contacts engages a mating connection surface of the filter housing assembly. The mating connection surface may be a circuit pad of a printed circuit board, wherein the contact mating portions are configured to be positioned in mechanical and electrical engagement with the circuit pads when the filter housing assembly is received within the filter base.

A water filter assembly for filtering water, adapted to be coupled to piping of a piped water system, the water filter apparatus comprising: a housing having first and second housing ends, the housing having an inlet and an outlet located at the first housing end, the second housing end having an opening, the housing being for removably receiving a filter element assembly through the opening in the second housing end, and a housing bottom cover releasably mountable over the opening in the second housing end. Preferably the assembly further comprises a filter head adapted to be coupled to piping of a piped water system and means for removably securing the first housing end to the filter head. Preferably the housing bottom cover is adapted to be secured to the housing via an interference fit.

A filter coupling device couples to a filter. The filter coupling device includes a plurality of joint members for connection to a plurality of connection openings of the filter. The filter coupling device also includes an arrangement switcher for switching an arrangement of the joint members between a first arrangement and a second arrangement.
