A water purification system (10) inlcudes an activated carbon filter (24) and a reverse-osmosis (RO)(26) filter. The activated carbon filter is typically formed with a central aperture that receives an upper portion of a central tube (28). Trie RO filter, which is positioned downstream from the carbon filter, may be formed around a perforated section of the central tube, the sstem further includes a head that is structured to received a sump (22) that contains the carbon and RO filters, as well as the central tube, an inlet (16) formed in the head enables unpurified feed water to flow into the carbon filter. A first channel (38), which is defined by an annular surface formed in the carbon filter and an outer surface of the central tube, enables water to flow into the RO filter. A channel within the central tube enables water to flow from the RO filter through the perforated section of the central tube, and into an outlet (30) formed within the head. |
