Abstract: A sock style filter is disclosed that incorporates the embossing of filtration media to create rigid raised geometry embodiments that prevent collapse between the upper and lower filtration media sides of the filter to maintain and ensure a flow passage of fluid inside the filter for flow to the pump or downstream system. The embossed rigid embodiments keep the filtration media from collapsing under suction and eliminates the use of secondary inserted structures; such as a plastic comb or folded net, or injection mold plastic ribs or bones onto or around the filtration media.

Abstract: Provided is a filter assembly including at least one end cap and at least one retainer mechanically locked to the end cap in a cavity and defining a region into which the bonding agent can flow to form a mechanical interlock with the retainer. Even if the bonding agent does not fully adhere to the end cap, the filter media will be secured in the end cap via the mechanical interlock of the bonding agent and retainer, thereby preventing end cap separation from the element.

Abstract: Embodiments of the technology disclosed herein include disposable filter cartridges for use with a water dispenser that dispenses hot water, flavored water, and chilled, sparkling water. An exemplary filter cartridge may be assembled by screwing or inserting a filter into filter cap until the filter cap engages a lock, such as an agnail lock, on the filter. Once engaged, the lock permanently secures the filter to the filter cap without adhesives, heat treatment, or curing. The filter cartridge includes one or more protrusions, or partial flanges, that twist into a recess formed by an injection-molded, two-piece locking assembly affixed to the water dispenser. Twisting the filter cartridge to a predetermined angle with respect to the locking assembly locks the filter cartridge into place. In some embodiments, the locking assembly and the filter cartridge audibly “click” or “snap” to indicate that they are secured together.

Abstract: A liquid recovery filter assembly for recovering filtered liquid trapped within a core or downstream side of a filter element. Multiple embodiments each include a recovery port and a recovery filter in fluid communication with the core or downstream side of the filter element. The recovery port is opened following filtration operations to permit and to facilitate filtered liquid to flow from a downstream or outlet port, thus allowing recovery of liquid remaining in the filter core or downstream side following filtering operations. The recovery filter permits the introduction of pressurized gas to force the filtered liquids from the filter assembly without compromising the sterility and/or non-contaminant condition of the liquid.
