behind choosing copper water vessels for daily wellness.

Rooted in Tradition. Backed by Research.

Copper has been used to store and purify water for thousands of years — long before modern science had the tools to explain why it worked. From ancient Ayurvedic practice to contemporary microbiology, the evidence has only grown stronger. Studies by researchers such as V.B. Preethi Sudha, D. Patel, and Ravi Marine have documented copper's measurable impact on water quality in controlled conditions.

In a landmark study, water stored in copper vessels showed a significant reduction in coliform bacteria — including E. coli — within hours of contact. The mechanism is well understood: copper ions disrupt bacterial cell membranes, preventing reproduction and eventually eliminating contamination entirely through what scientists call the Oligodynamic Effect.

Separate research confirmed that copper concentration in stored water increases gradually but stays well within WHO and US EPA safe limits — even after 168 hours of continuous storage. The result is water that is not just cleaner, but carries trace copper your body can actually use.

Researches & Insights


Before we had antibiotics — before we even knew what bacteria were — we already knew that copper had this 'magical quality' that stopped diseases. The earliest recorded medical use of copper is from around 4,500 years ago, where it was described as being used to sterilise wounds and drinking water.

When drinking-water contaminated with bacteria was stored in copper pots for 16 hours at room temperature, no bacteria could be recovered on the culture medium. Copper vessels are passive, requiring no fuel, electricity, or replaceable filters to operate or maintain.

Copper is an essential trace element in human diet as it is directly involved in maintenance and development of immune system as well as the functioning of several enzymes, bone strength, red and white cell maturation and brain development.

Water stored in a copper container for up to 168 hours showed an increase in copper concentration over time, but it remained within safe limits according to both the World Health Organization and the United States Environmental Protection Agency.
