Abstract:
1. A portable hand held water purification device comprising: a container suitable for grasping in a user's hand with said container including a water chamber therein; an opening in the container for introducing non-potable water to be purified into the water chamber; a drinking tube having a first end located within said container and a second end extending out of said container; a housing containing a porous structure located proximal said first end of said drinking tube; a water purification material located within said housing on the porous structure, said water purification material retained in a water contacting condition in said water chamber, said water purification material comprises a source of silver ions and a compound containing a hydantoin ring whereby the solubility of the silver ions in the non-potable water is increased by the presence of the compound containing the hydantoin ring therein to thereby enhance the ability of the water purification material to quickly convert the non-potable water into potable water without the aid of additional water purification agents; and a filter media located between said water purification material and said second end of said drinking tube, said filter media lowering the level of silver ions in said water before ingestion by the user through said drinking tube.
