A housing of the filter cartridge has an interface positioned at an outer surface of the housing. The interface is configured to engage with a post of the support ring in order to mount the filter cartridge to the manifold.

Abstract: A liquid filter assembly is provided for an appliance. The liquid filter assembly may define an axial direction and a radial direction. The assembly may also include a filter medium, a housing, a pair of end caps, one or more interlocking ring, and/or a leveling tube. The filter medium may extend along the axial direction between a first end and a second end. The filter medium may define an interior passage to receive liquid passed through the filter medium. The housing may be disposed about the filter medium. The housing may define a liquid inlet opposite the first end of the filter medium.

Abstract: A filter cartridge includes a filter medium disposed within a housing. At least one lug is mounted to the housing at a port of the housing. The lug is sized, positioned and/or oriented such that the filter cartridge couples to a manifold in one orientation. As an example, a cross-sectional shape of a first lug mounted to the housing may be different than a cross-sectional shape of a second lug mounted to the housing.

Abstract: A passive fluid dosing assembly and system is provided. The passive fluid dosing system may include a passive dosing body, a pressure plate, and a treatment enclosure. The passive dosing body may define a primary flow path and a liquid treatment path. The primary flow path may be defined between a fluid inlet and a fluid outlet. The liquid treatment path may be defined between a high pressure port and a low pressure port, bypassing a portion of the primary flow path. The pressure plate may be disposed within the passive dosing body between the high pressure port and the low pressure port. The pressure plate may define an internal orifice. The treatment enclosure may be positioned in fluid communication between the high pressure port and the low pressure port along the liquid treatment path. The treatment enclosure may define a solute chamber housing a dosed media.

Abstract: A filter for a non-plumbed appliance is provided. The filter includes a filter housing defining a filter chamber. A filter medium is positioned within the filter chamber, each end of the filter medium being enclosed by an endcap formed from a resilient material, such as molded silicone or a thermoplastic elastomer. The endcaps slide on the ends of the filter media with no need for adhesive and form a fluid seal with both the filter media and the filter housing once installed. One or more fluid bypass channels may be defined by the filter housing or in the endcaps to allow water to flow as desired within the filter chamber. The resulting filter requires fewer components and less assembly time while improving filtration performance and reliability.

Abstract: A performance indication device for a filter is provided. The performance indication device includes a water metering device to convert the energy of water flowing through the filter into mechanical rotation of a drive gear. A gear reduction assembly operably couples the drive gear to a valve gear and reduces the rotational speed of the valve gear relative to the drive gear. A flow controlling device is operably coupled to the valve gear and is configured to reduce or terminate the flow of water through the performance indication device and the filter when a target flow capacity is reached. The performance indication device thus provides an accurate indication to the user as to when the filter capacity has been expended without the need for a complex control system or communication link or any modification of the appliance in which the filter is installed.

Abstract: A filter for a non-plumbed appliance is provided. The filter includes a filter housing having a sidewall extending along a longitudinal direction between a first end wall and a second end wall. A flow distribution channel is also defined by the sidewall of the filter housing, the flow distribution channel extending outwardly from the sidewall along the radial direction and along the longitudinal direction between the flow aperture and the first end wall of the filter housing. The flow distribution channel equalizes the pressure gradient on the outer surface of the filter media, resulting in an improved flow pattern, increased clogging resistance, and improved filter performance capacity.

Abstract: A filter for a non-plumbed appliance is provided. The filter includes a filter housing defining a filter chamber. A filter inlet and a filter outlet are positioned along a bottom portion of the filter housing, and filter media is positioned within the filter chamber to remove contaminants from water flowing through the filter media. A divider wall is positioned within the filter chamber to direct the flow of water through a flow aperture at a top portion of the filter chamber, such that the filter chamber remains filled with water during operation. As a result, the filter media remains completely submerged, thereby improving filtration performance, reducing pressure drop, and more evenly depleting the filter media.

Abstract: Non-plumbed appliances and filters are provided. A filter includes a body which includes a sidewall extending along a longitudinal axis between a first end wall and a second end wall, the body defining a body interior. The filter further includes an inlet defined in the body, and a nozzle protruding from the second end wall along the longitudinal axis and defining an outlet, the nozzle offset along an outer surface of the second end wall from a centroid of the outer surface. The filter further includes a tab configured on the body, and a filter medium disposed within the body interior, the filter medium operable to remove contaminants from water flowing through the filter medium.

Abstract: Audible features are provided for a fluid filter assembly and a filter cartridge for use with a fluid filter assembly. The audible features generate sound when the filter cartridge is installed in the filter system so as to provide a signal indicating proper installation. Sound can also be created when the filter cartridge is removed. The filter system can also be provided with features for reducing clogging of the fluid path leading to the filter element.
