A single-use device for filtration of a large volume of medium comprises a plurality of single-use filter units, at least some of which, preferably all of which, are connected to each other by rigid pipes. The filter units include at least one prefilter and at least one main filter for virus filtration which is configured as a hollow fiber capsule.

An improved cartridge housing assembly and distributor is provided for a water filtration system installed at a point-of-use or a point-of entry of plumbing networks in buildings. The improvements include a mechanism for actuating a shut-off valve and a pressure-relief valve upon removing the housing assembly from the distributor, a bayonet-type mount between the housing assembly and the distributor, a housing lid to prevent spilling of water when the housing assembly is removed from the distributor, and fastener clips that allow for modular attachment of the distributor to plumbing fittings and a mounting bracket.

A purification device is provided that includes a porous container, purification media retained in the porous container, and a flow controller integral to the porous container. A purification device is also provided that includes a porous elastic container, purification media, and a flow controller. The porous elastic container has a pocket formed therein. The purification media is compressibly retained in the porous elastic container. The flow controller is elastically retained in the pocket of the porous elastic container.

A purification device comprises a main body having an opening in a front-face thereof; a rotator disposed in the opening to be rotatably mounted on the main body; a manipulation structure spaced from and above the rotator and rotatably connected to a top face of the main body, the manipulation structure protruding forward of the main body; and a water-outlet including; a first cover fixed to the rotator through the opening, the first cover protruding forward of the main body, and a top of the first cover being connected to a bottom of the manipulation structure; a second cover vertically movable while being held in contact with the first cover; and a nozzle on a bottom of the second cover; wherein when the second cover rises to a highest level, a top of the second cover is located in a space between the rotator and the manipulation structure.

A filtration system has a filter unit and a holder module. The filter unit has an inlet side and an outlet side being opposite each other, and has at least one filter module. The holder module has at least one holder element and two tightening assemblies. The at least one holder element fixes the at least one filter module, and the tightening assemblies are respectively mounted at the inlet side and the outlet side of the filter unit. The quantities of the filter modules of the filter unit may be increased or decreased.

A pipeline filter assembly comprising a base assembly, an outer wall, and a lid assembly. The base assembly comprises a filter base, a base plate, and a support collar. The outer wall has a lower end portion and an upper end portion, wherein the lower end portion is coupled to the base assembly and the upper end portion comprises a lower collar. The lower collar comprising at least one lock notch spaced around an exterior surface thereof. The lid assembly comprises an upper collar and an upper cover. The upper collar comprises at least one housing that projects from the upper collar, at least one biasing clip pivotally mounted within the housing for releasable engagement with the lock notch, and at least one biasing spring that biases its corresponding biasing clip to a locked position around a corresponding lock notch.

A filter manifold is provided for processing fluid being provided to a fluid dispenser, featuring a new and unique combination of a mounting bracket, a filter cartridge and an accumulator cartridge. The mounting bracket is configured with porting connections. The filter cartridge may include a filter cartridge porting connection configured to plumb into one of the porting connections on the mounting bracket and also configured to filter the fluid being provided to the fluid dispenser. The accumulator cartridge includes an accumulator cartridge porting connection configured to plumb into another one of the porting connections on the mounting bracket and also configured to receive, accumulate and provide the fluid to the filter cartridge to be filtered before being provided to the fluid dispenser.

A fluid filter apparatus comprising an upper housing shell; a lower housing shell; a pleat pack element comprising a peripheral frame and a folded pleated media. The frame is at least partially molded over the media to secure the media in the frame, and the media comprises two or more types of media of different densities from each other. A flow control element is disposed for changing the proportion of flow between the first media and the second media responsive to changes in at least one of temperature, pressure, flow rate and/or viscosity of the fluid.

A purification device comprises a main body having an opening in a front-face thereof; a rotator disposed in the opening to be rotatably mounted on the main body; a manipulation structure spaced from and above the rotator and rotatably connected to a top face of the main body, the manipulation structure protruding forward of the main body; and a water-outlet including; a first cover fixed to the rotator through the opening, the first cover protruding forward of the main body, and a top of the first cover being connected to a bottom of the manipulation structure; a second cover vertically movable while being held in contact with the first cover; and a nozzle on a bottom of the second cover; wherein when the second cover rises to a highest level, a top of the second cover is located in a space between the rotator and the manipulation structure.
