An improvement in a water filter cartridge of the type having a substantially frustoconical vessel member defining a vertical axis and containing a granular purifying agent which is insoluble in water. The vessel member has a screen-like end wall portion at the lower end thereof. A hollow substantially frustoconical cover member is attached to the vessel member and coaxial with the vertical axis thereof. The cover member defines an annular rim portion and a first slanted portion extending upwardly and inwardly from the rim portion, and a substantially flat-topped second portion, the first portion having a multiplicity of vertically oriented water entry flow slots arrayed therearound. The vessel member and the cover member together define a container for receiving and retaining said granular purifying agent therein. The water filter cartridge is for use in a water filtration device. The improvement comprises the provision of a water flow directing ring positioned above the granular purifying agent. The water flow directing ring has a substantially peripherally disposed main body portion shaped and dimensioned to contact the container at its interior surface at a level above the granular purifying agent and below the water entry flow slots. At least one drip arm extends radially inwardly from the main body portion in overlying relation to the granular purifying agent.
