ANVEERUS > Why Copper
For thousands of years, long before they knew about germs or viruses, people have known of copper’s disinfectant power - role of copper in supporting and maintaining good health. Copper and health throughout history started long ago from the ancient Egyptians, to the Greeks, to the Aztecs, to the Roman empire, to 19th century France, and finally to the modern era.

Copper’s Virus-Killing Powers Were Known Even to the Ancients
United States Environmental Protection Agency (EPA) has registered about 400 copper surfaces as antimicrobial.
Heavy metals including gold and silver are antibacterial, but copper’s specific atomic makeup gives it extra killing power. Copper has a free electron in its outer orbital shell of electrons that easily takes part in oxidation-reduction reactions (which also makes the metal a good conductor). As a result, it becomes a “molecular oxygen grenade.” Silver and gold don’t have the free electron, so they are less reactive.
Copper kills in other ways as well. When a microbe lands on copper, ions blast the pathogen like an onslaught of missiles, preventing cell respiration and punching holes in the cell membrane or viral coating and creating free radicals that accelerate the kill, especially on dry surfaces. Most importantly, the ions seek and destroy the DNA and RNA inside a bacteria or virus, preventing the mutations that create drug-resistant superbugs.
