Abstract: In various aspects, a water supply assembly comprises a water assembly housing, a water pump positioned within the water assembly housing and comprising a water pump inlet and a water pump outlet, a water inlet and a water outlet, and a filter element fluidly coupled to the water pump. The filter element is positioned within the water assembly housing along a water flow path between the water pump outlet and the water outlet and the water inlet is positioned along the water flow path upstream of the water pump inlet. The water supply assembly may be mounted on a water supply tank in a water purifier.

Abstract: A water filter is provided. The water filter includes a filtration material and a filter housing spaced for accommodating at least a portion of the filtration material therein. The water filter also includes a housing cap coupled to an upper end of the filter housing for enclosing the filtration material within the water filter. The housing cap includes an upper portion, a lower portion, and a channel formed through the upper portion and the lower portion. The water filter also includes an interface adapter accommodated in the channel, wherein the interface adapter includes a side wall vertically extending from an upper surface of the interface adapter and partially around a perimeter of the upper surface, and a projection vertically extending from the upper surface, wherein the projection is integrally formed with the upper surface and a portion of the side wall.

Abstract: A water filter element for use within a water purification system includes a housing, a locking protrusion, and a handle. The housing comprises a first end comprising a water inlet and a water outlet and a second end opposite the first end. The locking protrusion is positioned on the housing proximate the second end of the housing, and the handle is disposed on the second end of the housing. The handle comprises an outer side oriented away from the first end of the housing. When the water filter element is installed within the water purification system, the outer side of the handle causes the second end of the housing to be radially displaced such that the locking protrusion is engaged by a lock of the water purification system. Water filter assemblies including the water filter element and methods of installing and removing the water filter element are also described.
