Your water bottle should be doing more than holding water.
Most bottles store water.
This one purifies it.
Every time you fill this bottle and leave it to rest overnight, on your desk, on your bedside table, trace copper ions are quietly moving into the water. Eliminating bacteria. Alkalising. Charging the water at a cellular level in a way that no stainless steel or plastic bottle ever could.
This isn't a new idea. It's a 5,000-year-old one. Ayurvedic medicine called it Tamra Jal — copper water — and prescribed it as a daily morning ritual for immunity, digestion, and energy.
Modern science has spent the last few years working out why it was right.
What happens in 8 hours
Fill it before bed. Here's what the water becomes by morning.
Here's what they found in a litre of bottled water.
In January 2024, researchers at Columbia and Rutgers Universities published a study that made headlines around the world.
They found 240,000 plastic particles in a single litre of standard bottled water.
90% of them were nanoplastics — particles so small they can cross cell membranes, enter the bloodstream, and reach organs. Subsequent research has detected them in human lungs, blood, and placentas.
And here's the part most people haven't thought about yet:
Your stainless steel bottle has a plastic lid. A silicone seal. Plastic threading your water contacts every single day.
You switched from single-use plastic. Good. But the problem didn't fully go away — it just got smaller and harder to see.
A Copperwell bottle is different. The water inside touches only one material from the moment you fill it to the moment you drink:
No plastic. No liner. No coating. No compromise.
Built to last a lifetime. Designed to use every day.
The hammered finish isn't decorative, it's the mark of a bottle made by hand, one at a time, by craftspeople who have been working copper for generations. No two are identical. The surface you're holding has been shaped by a human, not a machine.
The interior is left deliberately unlined and uncoated. That's not cost-cutting, it's the point. A lined copper bottle doesn't give you copper water. It gives you a copper-coloured water bottle. We didn't build that.
The simplest healthy habit you'll build this year.
What the research says about copper.
On heart health:
A longitudinal study published in BMC Public Health in March 2025, analysing nearly 20 years of US health data, found that higher dietary copper intake was associated with significantly lower cardiovascular disease prevalence and mortality. Researchers identified an optimal copper threshold — and found the protective effect was particularly pronounced in people with high blood pressure.

On brain health:
A study published in Scientific Reports in July 2025, analysing data from 2,420 adults over 60, found that people with optimal dietary copper intake scored measurably higher on memory and cognitive processing tests. Separately, researchers at Rush University found that higher copper concentrations in brain tissue were associated with slower cognitive decline and fewer Alzheimer's-related markers.

On water purification:
A peer-reviewed study published in the Journal of Health, Population and Nutrition found that water contaminated with dangerous bacteria — including E. coli, Salmonella, and Vibrio cholerae — showed zero recoverable bacteria after 16 hours of storage in copper vessels. Zero. Not reduced. Eliminated.

These findings relate to dietary copper intake and copper's antimicrobial properties. We share them because we believe informed customers make better decisions. We make no therapeutic claims about this product.
Not all bottles are created equal.
Stainless steel is better than single-use plastic. We'll give it that. But "better than plastic" is a low bar. We built for higher.

Try it for 30 days. On us.
We're confident enough in this bottle that we'll take it back, no questions asked, within 30 days if you don't love it.
We can offer that because less than 1% of customers ever ask for a refund. Not because we make it hard — because the bottle earns it.
If it doesn't become part of your morning, we don't want your money. Simple.
Good Questions. Honest Answers.
Q: Will it actually taste metallic?
Q: Will it actually taste metallic?
Not if you use it correctly. A faint copper taste on first use is normal — it's the bottle telling you it's real. After your initial rinse and first fill, most customers describe the water as cleaner, crisper, and cooler tasting than what they drink from stainless or plastic. If you notice a strong metallic taste at any point, check that you're using plain still water (no citrus, no carbonation) and that you're cleaning regularly with our lemon-and-salt method.
Q: How do I look after it?
Q: How do I look after it?
Easier than you think. Daily: a quick warm water rinse. Weekly: a gentle scrub inside with half a lemon dipped in salt, then rinse thoroughly. That's genuinely it. No chemicals, no dishwasher, no special equipment. The natural patina (darkening) that develops over time is not a defect — it's proof the copper is real and active. If you prefer a shinier look, your weekly lemon-and-salt routine keeps it looking new.
Q: Why is my bottle changing colour?
Q: Why is my bottle changing colour?
That's the copper doing exactly what pure copper does — developing a natural patina through oxidation. It's cosmetic, not functional, and it doesn't affect the safety or the benefits of the water. Think of it the way you think about a good leather wallet or a cast iron pan: it's aging beautifully, not degrading. If you prefer bright copper, the lemon-and-salt clean restores it in about 60 seconds.
Q: How much copper am I actually getting from the water?
Q: How much copper am I actually getting from the water?
A meaningful trace amount — within safe dietary ranges and well below any level of concern. Studies on water stored in copper vessels overnight have found copper ion concentration in the range of 0.01–0.1 mg/L — comparable to what you'd find in many copper-piped water systems. The recommended daily intake of copper for adults is 0.9mg/day. Two glasses of copper water contributes a fraction of that — enough to be beneficial, not enough to be a concern when used as directed.
Q: I already have a stainless steel bottle. Why should I switch?
Q: I already have a stainless steel bottle. Why should I switch?
Because stainless steel stores water — it doesn't do anything to it. It also has a plastic lid, a silicone seal, and threading that your water contacts every day. We're not here to alarm you — stainless steel is significantly better than single-use plastic. But if you want water that arrives in your glass genuinely cleaner, bacterially purified, and mineralised — stainless can't do that. Copper can. And unlike your stainless bottle, this one won't need replacing.
Q: How is this different from a lined copper bottle?
Q: How is this different from a lined copper bottle?
A lined or lacquered copper bottle is at best, a copper-coloured water bottle. The lining creates a barrier between the water and the copper, which means the oligodynamic effect (bacteria elimination), mineral transfer, and alkalisation don't happen. Our bottle is deliberately unlined and uncoated. The water touches pure copper from the moment you fill it. That's not a compromise we were willing to make.
Q: Can I use it for hot drinks, juice, or sparkling water?
Q: Can I use it for hot drinks, juice, or sparkling water?
Room temperature and cold still water only. Acidic liquids (juice, citrus-infused water, kombucha) react with the copper and will accelerate patina, affect taste, and potentially deliver more copper than intended. Hot liquids can cause burns and damage the bottle over time. Sparkling water's carbonation creates a similar acidic reaction. Keep it simple — pure water, overnight, every day. That's the ritual that works.
