The regeneration medium filter container includes a housing, an inlet, and an outlet. The diffuser is fluidly connected to the inlet and disposed within the regeneration medium filter container. The at least one pump is configured to direct water through the water filtration system. The housing of the regeneration medium filter container includes a concave lower portion centered about the vertical axis of the container. The position of the diffuser along the height of the regeneration medium filter container is determined at least by the ratio of the height to the inner diameter of the regeneration medium filter container and the radius of curvature of the concave lower portion. A regeneration medium filter container is also disclosed, comprising a diffuser having asymmetrically spaced apertures. This filtration system can only filter water and cannot filter water containing a large amount of impurities. Its overall filtration effect is average. Utility Model Content
