Why Copper?

Copper is one of the few materials that is naturally antibacterial, endlessly recyclable, and built to last.

We use pure copper for its durability, sustainability, and ability to keep water fresh, without the need for plastics or coatings.

Every Nira Earth piece is made to serve you for years, with zero waste and timeless design.

But Why Now?

Because we’re at a turning point.

More than 2 billion people around the world lack access to safe drinking water.
Microplastics have been found in 94% of U.S. tap water samples.
Plastic bottles continue to flood oceans, releasing toxins and never truly breaking down.

Copper is the most natural, sustainable upgrade we have. It is:

• 100% recyclable

• Naturally antibacterial

• Built to last a lifetime

• Zero-waste when properly cared for

For over 4,000 years, cultures from Egypt to Greece, Rome and India have stored drinking water in copper vessels. They valued copper's ability to keep water fresh and safe.

These benefits are now confirmed by modern science.

What You Should Know About Copper?

Copper evolves, and that’s part of its beauty.

It may develop a natural patina, a soft matte layer that reflects its living surface. This doesn’t affect its benefits — in fact, it adds character.

To keep your copper vessel in its best form:

• Rinse daily with warm water

• Avoid harsh soaps or dishwashers — copper prefers a gentle han

• Polish occasionally with lemon + salt, or a natural copper cleaner

• Store dry to avoid water stains

• Use for still water only — not for acidic drinks, citrus, or hot beverages

Treat it like something alive, because, in many ways, it is.

It asks for care, but gives back far more in return.

It purifies, heals, and lasts.

With every sip, it’s elevating your water.

Choose Copper.

Choose Nira Earth.

1. Natural Antimicrobial Effect

Study Title: Storing drinking-water in copper pots kills contaminating diarrhoeagenic bacteria
Published in: Journal of Health, Population & Nutrition (2012)
Summary: This study demonstrated that storing water in copper pots for 16 hours at room temperature killed harmful bacteria such as E. coli, Salmonella Paratyphi, and Shigella flexneri.

2. Practical Application in Households

Study Title: Killing of enteric bacteria in drinking water by a copper device for use in the home
Published in: Indian Journal of Medical Research (2007)
Summary: Researchers tested copper water storage at the household level and found effective elimination of enteric pathogens, including Vibrio cholerae and E. coli, validating its real-world antimicrobial use.

3. Biological Impact on Pathogens

Study Title: A Murine Model to Study the Antibacterial Effect of Copper on Infectivity of Salmonella Enterica Serovar Typhimurium
Published in: International Journal of Environmental Research and Public Health (2011)
Summary: This in vivo study on mice showed that exposure to copper significantly reduced bacterial infectivity, suggesting copper’s health-protective role extends beyond water storage to biological effects.

4. Safe Copper Leaching Levels

Study Title: Water quality and risk assessment of copper content in drinking water stored in copper containers
Published in: Desalination and Water Treatment (2021)
Summary: Water stored in copper containers remained within safe copper content limits set by WHO and EPA, even after extended storage. This confirms both the safety and long-term usability of copper vessels.

Scientific evidence supports what traditional systems like Ayurveda have long taught: storing drinking water in copper vessels is an effective, sustainable, and health-supportive practice.

These studies confirm copper’s ability to purify water, reduce bacterial risks, and do so without introducing harmful substances — making it a meaningful alternative to plastic or chemically treated water containers.
