Bacteria, yeasts, and viruses are rapidly killed on metallic copper surfaces, and the term “contact killing” has been coined for this process. The antimicrobial activity of copper and copper alloy is now well established, and copper has recently been registered at the US Environmental Protection Agency as the first solid antimicrobial material. The oldest recorded medical use of copper is mentioned in the Smith Papyrus, one of the oldest known books. The Egyptian medical text, written between 2600 and 2200 B.C. describes the application of copper to sterilize chest wounds and drinking water. This product does not cure anything. It is a preventative tool to keep bacteria and viruses out of the nose.
