ABSTRACT:
A water treatment system and related components for reducing contaminants in normal drinking water are provided. An enlongated tube has first and second ends and is connected with an interference fit at its first end to the interior surface of a neck of a conventional bottle. Water treatment media is disposed within the tube adjacent its second end, such as activated charcoal, silver impregnated media, ion exchange resins, or calcium and/or magnesium leaching material. The tube includes a flange adjacent its first end which minimizes the possibility that water will enter the bottle except by flowing through the open first end of the tube. A cap is provided for disposition over the tube, a lower portion of the cap sealing the open first end of the tube to prevent water from flowing through it, and apertured substantially 360 degrees around its circumference to allow free flow of water from the bottle which has already been treated by the treatment media wuen an upper portion of said cap is moved axially relative to the lower portion from a closed to an open position. An adaptor is also provided for converting a snap-on cap bottle neck to a screw-on cap bottle neck so that a screw-on type cap may be utilized with either type bottle neck.
