  • Publication number: 20160082392
    Abstract: A reverse osmosis filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with the raw water ingress, permeate egress, and reject water egress. The reverse osmosis filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

  • Publication number: 20160059155
    Abstract: A carafe filter cartridge for reverse flow applications where the filter housing and filter media top end cap directs unfiltered fluid into the filter media annular cavity, through the filter media sidewalls. And the filter media bottom end cap prohibits egress, filter fluid from exiting through the filter media end or the annular cavity. Filtered fluid is instead directed out through apertures in the filter housing sidewall. The optimum ratio of annular cavity and/or top end cap orifice area to the respective perimeter is determined to remove the risk of detrimental fluid flow due to air bubble generation.

  • Publication number: 20150284260
    Abstract: A countertop water dispenser having a three tiered reservoir system for filtering water and providing immediate dispensing via a spigot, and simultaneously filling a removable pitcher for transporting filtered water to another location. Water flow in the three tiered reservoir system may be controlled by flow valves that float with rising water to stop water flow when a maximum fill level is reached in a reservoir. A flow valve is provided in the middle reservoir as well as the lower reservoir to control the amount of filtered water in each reservoir. An air vent is provided on a filter housing, the air vent venting to a heightened arcuate rib on the countertop dispenser cover. The removable pitcher is mated to the lower reservoir via a pitcher filling mechanism that includes respective plunger or pin valves to allow water to flow into the pitcher when the lower reservoir is filled with water above or equal to the height of the pitcher filling mechanism.

  • Patent number: 9061225
    Abstract: A receiver for a cassette filter housing having an upper housing surface. The receiver comprises an arrow shaped elongated member having ends. The elongated member may be parallel with an upper surface of the cassette and may include a base portion attached to the upper housing surface the cross-section of which is a substantially planer segment extending to the upper surface. The elongated member includes an upper receiver portion having at least one cavaliered retaining surface. The receiver includes a first reinforcement member extending outward from the base portion adjacent one of the ends of the elongated member and perpendicular to the elongated member, and a second reinforcement member extending outward from the base portion adjacent the opposite end of the elongated member and perpendicular to the elongated member the reinforcement members affixed to the base portion and the upper housing surface.

  • Publication number: 20150122724
    Abstract: The present invention presents a filtration system with an integrated manifold valve. The filtration system employs only one pivotal component—the pivoting of the manifold. The manifold valve includes a dual aperture design for a two-fold alignment scheme with the ingress and egress lines of the fluid source. The invention is free of multi-component rotary valve with internal, rotatable parts, or an activation component, such as a handle, for initiating the rotary valve, allowing the user to rotate the rotational components thereof. The reduction in moveable components in this design reduces the likelihood of failure and increases the reliability of the filtration system.

  • Publication number: 20150014240
    Abstract: A gravity filter media fabricated from multiple spiral wound or pleated layers, where different layers are designed for specific contaminant removal process and the layers are combined into a single pack for ease of use. The layers or fiber sheets are chemically treated for contaminant removal, with different layers having different chemical treatments, or the layers are immobilized with particles of various sizes for use as low contact-time adsorbents, with different layers having different immobilized particles, or the pore structure is varied from one fiber sheet to another—one being a tight pore structure, and the other being a more open pore structure, or any combination thereof. When using immobilized particles, the immobilized particles can be chemically treated for the specific removal of targeted contaminants, and multi-layered for custom designed removal of specific contaminants.

  • Publication number: 20150014233
    Abstract: A filter for gravity-fed applications, having filter media with a hollow center, the filter being generally prone to a degradation or cessation in fluid flow due to air entrapment or air lock within the filter housing cavity, which develops during filtering. A diffuser element is introduced to pierce the entrapped air bubble, the diffuser element being an elongated structure connected to the filter housing top end cap and extending through the entrapped air bubble to the filter media.
