Copper

Ayurvedic texts mention the use of copper vessels for drinking water. Copper is the only metal with anti-bacterial properties, which proved true even during the 1800s when copper mine workers were immune to Cholera. Using copper to water can purify it. It can kill all the microorganisms, moulds, fungi, algae and bacteria, present in the water that could be harmful to the body and make the water perfectly fit for drinking. Copper is an essential trace mineral that is vital to human health.
