For the optimisation crowd
You optimise everything you put in your body. Except the thing you drink most.
Sleep, training, supplements, bloodwork, all dialled in. Then you pour two or three litres a day of tap water carrying forever chemicals and microplastics, contaminants that bioaccumulate over decades. Your longevity stack has a leak, and it's the highest-volume input you never touched.
The protocol you already run
Your stack is dialled in. One input is still on default.
You measure, dose and iterate on everything. Look at what you've already optimised.
Your stack
- Sleep & circadian light
- Zone 2 & VO₂ max
- Sauna & cold exposure
- Creatine & protein targets
- Omega-3 & magnesium
- Bloodwork & biomarkers
- HRV & recovery tracking
- Nailed the supplement stack
You track HRV to two decimal places, then drink the single highest-volume input in your day straight off the tap, unmeasured.
The highest-leverage input you skipped
You consume more water than any supplement. By a distance.
Longevity is a long game about lowering lifetime load. Which makes the two or three litres you drink daily, and what rides along in it, one of the most leveraged inputs you can clean up.
- Forever chemicals bioaccumulate for years. In a game measured in decades, your baseline load compounds.
- Microplastics have now been detected in human blood and even in arterial plaque, and boiling doesn't remove them.
- Mains water isn't treated to remove either. Water company treatment targets safety and bacteria, not forever chemicals or plastic.
- It's the input you never measured. You optimise the 5-gram doses and ignore the 3-litre one.
Every other input in your stack has a spec. Your water has whatever came out of the tap.
Cleaning it up is one of the rare upgrades that's both high-leverage and near-zero ongoing effort.
Why the obvious answers underdeliver
Bottled, jug and even RO all miss.
- Bottled "spring" water is one of the largest sources of microplastics there is. You're paying a premium for plastic-exposed water.
- Supermarket jug filters mostly handle taste and chlorine, and you're drinking from plastic that can shed microplastics back in. Independent testing has shown that many of these filters can actually increase heavy metal contamination such as aluminium by significant margins.
- Reverse osmosis strips the contaminants, but also strips the minerals, leaving flat, demineralised water, plus a tank, waste water and plumbing.
The spec you actually want: remove the load, keep the minerals.
Contaminants out, trace minerals and a mild alkaline pH left in. That's the target, and it's not what a jug or an RO tank gives you.

The Waters Co difference
Removes the load. Keeps the minerals.
The BIO 500 MAX runs tap water through 13 stages, removing up to 99.9% of fluoride via a patented nano carbon compound and up to 99% of chlorine, chemicals, heavy metals and bacteria, filtering microplastics down to 0.1 microns, then re-mineralising with 60+ bio-organic trace minerals at a naturally mild alkaline pH. Unlike reverse osmosis, you don't get flat, stripped water. And it's held in a 7 litre hand-blown glass reservoir, so no plastic touches the output.
- Targets forever chemicals, pesticides and herbicides, plus lead, fluoride, chlorine and bacteria.
- Re-mineralised, not stripped, 60+ trace minerals at pH 7.6 to 8.5, no RO deadness.
- Glass reservoir, BPA / BPB / BPS-free build, no plastic in contact with your water.
- No tank, no plumbing, no power, gravity-fed and effectively zero maintenance overhead.
13 stages of sterilising, filtration and mineral activation, held in hand-blown glass.
The spec
The output profile, on paper.
Fluoride removal
Patented nano carbon compound. Few filters touch it.
Filtration stages
Sterilising, filtration and mineral activation in one pass.
Microplastics & metals
Detected in blood and plaque. Filtered to 0.1 microns here.
Trace minerals
Re-mineralised, not stripped like RO water.
pH 7.6–8.5
Naturally mild alkaline. No additives, no gimmicks.
Glass reservoir
Hand blown, BPA / BPB / BPS-free. No plastic on the output.
The leverage
High leverage. Near-zero upkeep.
Most of your stack demands daily effort and repeat spend. This one is a single change that upgrades every glass you drink, for thousands of litres.
Your highest-volume input, now on spec.
Over the filter's life. A rounding error in any stack.
Or around 18 months, whichever comes first.
Zero friction, by design
On the worktop in minutes. No plumbing, no power.
Set it on the worktop
Compact and lightweight, assembled by hand in a couple of minutes. Gravity-fed, with no drilling, no electrician, no tank under the sink.
Fill the top with tap water
Gravity pulls it through all 13 stages into the 7 litre glass reservoir. Nothing to plug in, nothing to monitor.
Set and forget
One filter set runs up to 12,000 litres or around 18 months, and a filter reminder service means you don't have to track it. Roughly the lowest ongoing effort of anything in your protocol.
Glass, not plastic
BPA / BPB / BPS-free build.
Up to 12,000 litres
Per filter set, around 3p a litre.

From people who track everything
The upgrade they were annoyed they'd missed.
"I test bloods, track HRV, dial in every input, and water was the one I'd never touched. Which is embarrassing given it's what I consume most. Removes the load and keeps the minerals. Exactly the spec I wanted, no RO flatness."
"Was drinking bottled 'spring' water thinking I was optimising, then read what's actually in bottled water. Switched to this. Glass reservoir, re-mineralised, 13 stages with published removal figures. Finally a known spec instead of guesswork."
"Lowest-friction upgrade in my whole protocol. Sits on the worktop, no plumbing, and I've changed the filter once. Genuinely set and forget, which almost nothing in this space is."
Straight answers
The questions optimisers ask us.
Isn't reverse osmosis the gold standard?
RO removes contaminants, but it also strips the minerals, leaving flat, demineralised water, plus it needs a tank, produces waste water and usually plumbing. The BIO 500 MAX removes up to 99.9% of fluoride and up to 99% of chemicals, heavy metals and bacteria, filters microplastics to 0.1 microns, then re-mineralises with 60+ trace minerals. You get the removal without the deadness or the install.
Does it actually remove contaminants, or just improve taste?
Both. The 13-stage system removes up to 99.9% of fluoride and up to 99% of sediment, rust, bacteria, cysts, chlorine, chemicals and heavy metals, and filters particulates down to 0.1 microns. Waters Co backs its removal figures with independent lab testing and holds certifications from NSF International, ISO, CE, FDA and the Water Quality Association. Taste is the by-product, not the point.
What about PFAS specifically?
The filter targets forever chemicals, pesticides, herbicides and other volatile organic compounds as part of its removal profile. We publish a specific percentage for fluoride because that's what the lab data supports for this model. If PFAS is your primary concern, get in touch and we'll point you at the testing for the relevant system.
Why not just drink bottled spring water?
Bottled water is one of the largest sources of microplastics measured, and you're paying a premium for plastic-exposed water with no consistent spec. Filtering your own gives you a known output at roughly 3p a litre.
Is the alkaline pH claim legitimate?
The water sits naturally at a mild alkaline pH of 7.6 to 8.5 after mineralisation, with no additives or ionising gimmicks. If you prefer mineral-rich, mildly alkaline water, that's the profile you get. We won't stretch it into health claims beyond that.
What's the actual maintenance overhead?
Minimal. It's gravity-fed with no power, no plumbing and no tap connection. You top it up, and swap the filter set at up to 12,000 litres or around 18 months, whichever comes first. About as low-friction as an input gets.
