“Drinking tap water felt like playing hydration roulette.”
Louise-Jane Paul
One bottle, every situation.
The 4pm office tap.The one that tastes like the building’s pipes.
The gym water fountain.The one you use because you forgot a bottle, then regret it.
The hotel sink at 2am.Thirsty, jet-lagged, and not drinking that.
The supermarket shop.Hauling another six-pack home because the tap isn’t an option.
How it works
Fill it. Twist it. Drink.
No batteries, no charging your bottle, no firmware to update. Every sip passes through the cartridge before it reaches your mouth — the same way good water filters have worked for decades, built into something you can take with you.
- 1
A non-woven layer that catches sediment and rust before the water reaches the core. (Pre-filter)
- 2
The filter core. Jacobi coconut-shell activated carbon, carbon fibre, and heavy-metal removal media. Chlorine taste goes here. So do heavy metals like lead, copper and mercury. (Multi-media core)
- 3
A second non-woven layer that polishes the water on its way out of the cap. (Post-filter)
Why this, not that
You’ve already tried the alternatives.
Bottled water
Solves trust, but you carry it home, you pay every time, and the recycling bin tells the story.
A jug filter at home
Fine for the kitchen. Useless once you walk out the door.
Whatever tap is nearest
Hydration roulette. You know the drill.
A FlowPure filter bottle
The same filtration as a kitchen system, in something you can take with you.
Independently tested
Numbers from a third-party lab, not our marketing team.
No calibration, no recalculation. Same performance from the first sip to the last. The bottle’s body is BPA-free 304 stainless steel — the only thing your water touches between the tap and your mouth is filter media and metal.

What goes, what stays
What’s actually in your water — and what shouldn’t be.
From your pipes
Older plumbing leaches metal.
The metals older pipes give up to whatever flows through them.
- Lead
- Copper
- Mercury
From treatment
The ‘swimming pool’ smell.
What gets added to keep tap water safe in the network — and what you can taste.
- Residual chlorine
- Chlorine taste & odour
From the journey
Things that come along for the ride.
Picked up between the treatment plant and your glass — or your bottle.
- Sediment
- Rust
- PFAS
What stays in
We’re not stripping water.
The cartridge is built to leave the good stuff in — calcium, magnesium, trace minerals, the natural pH. We’re cleaning it up, not gutting it like an RO system would.

Why this exists
Filtered water shouldn’t end at your front door.
Most filter systems live in one place — a jug on the counter, a unit under the sink, a cartridge on the tap. None of them help at 4pm on the office floor, in a hotel bathroom at 2am, or on a path in the Lake District.
This bottle exists for the rest of the day. Same media you’d want at home, in something that fits in your bag.
30-day returns
Send the bottle back inside 30 days for a full refund.
Lifetime body warranty
If the stainless body ever fails — insulation, threads, anything structural — we replace it.

“Filled it at four different taps on a trip last month — office, hotel, gym, train station. Water tasted the same every time. That’s the whole point.”
Ann
“Chlorine odour gone instantly. No aftertaste — water actually tastes like water for the first time.”
Ian Gentry
“Already had the FlowPure tap filter at home. Added the bottle for the rest of my day — double-filtered water everywhere I go. Couldn’t go back.”
Mike R.
“Refilling the bottle from the kitchen tap is now the morning routine. The kids actually drink water now — no more half-empty plastic bottles coming home in lunchboxes.”

Common questions
The honest answers.
Around 150 litres of filtered water through the cap — roughly two months for an average user. Heavier use shortens that. The Subscribe & Save plan ships replacements at the right cadence by default — skip or cancel anytime.
The cartridge that ships with the bottle handles chlorine taste, heavy metals like lead, copper and mercury, sediment and rust, and PFAS. It’s the same media you’d want in a kitchen filter — just built into a cap you can take anywhere.
Lifetime warranty on the stainless body — if the insulation fails, the threads strip, anything structural goes, we replace it. 30-day returns for any reason: send it back for a full refund. Cartridges are consumables.
Yes — in your account, two clicks. You can also pause, skip a month, or change cadence whenever you want.
The 680 ml fits standard car cup-holders. The 1 L is a touch wider — fine in most cars, but worth measuring if you have a tight one.
