Clean water shouldn't be this hard.
The UK has some of the most regulated tap water in the world. Regulated doesn't mean pure. Here's why that matters — and what we're doing about it.
To make genuinely pure drinking water accessible to every UK home — without the plastic waste, without the plumbing bills, and without the compromises.
Your tap water is treated. That doesn't mean it's clean.
The problem isn't regulation. It's what happens between the treatment plant and your glass.
Chlorine & Disinfection By-products
UK water suppliers use chlorine to kill bacteria. It works — but leaves a taste, an odour, and chemical by-products that travel through your pipes and into your glass.
Microplastics
Studies have found microplastics in over 72% of UK tap water samples. Particles too small to see, too persistent to ignore, and not fully removed by standard treatment.
Ageing Infrastructure
Some UK water pipes date back to the Victorian era. Lead, copper, and sediment can leach into your supply long after water leaves the treatment plant.
Regional Variation
Water quality in London differs from Manchester, which differs from Bristol. Your neighbour’s water quality can differ from yours depending on local pipe conditions.
Limescale & Hard Water
Over 80% of UK homes have hard water. Limescale builds up in your kettle, your pipes, and your appliances — and affects the taste of everything you drink.
Pitcher filters catch some of it. They miss most of it. Under-sink systems work — if you have £2,000 and a plumber. Bottled water? The UK uses 7.7 billion plastic bottles a year. That's not a solution. That's a different problem.
Pluvia exists because nothing else was good enough.
A countertop reverse osmosis purifier that removes 99.9% of contaminants — chlorine, microplastics, lead, limescale, and more — through 4-stage filtration. No plumber. No permanent changes to your kitchen. Installed and pouring pure water in under 30 minutes.
Hot, cold, and room temperature. One unit replacing your kettle, your filter jug, and your bottled water habit. NSF and WQA certified, designed by a team with 17 years of UK water purification experience, and backed by a 30-day risk-free trial.
The most sustainable bottle is the one you never buy.

Designed for longevity, not landfill
Most people who buy bottled water do it because they don't trust what comes from the tap — not because they want to generate waste. Pluvia eliminates the reason. When your tap water is genuinely pure, the bottles stop making sense.
Replaceable filters — not disposable units. Recyclable packaging. A product built to last years, not months. Because the most sustainable product is the one you don't have to replace.
Pure water access shouldn't depend on your postcode.
We started with Pluvia — a single, uncompromising product. But our goal is larger: to make advanced water purification standard in UK homes, not a luxury.
That means continuing to listen. Continuing to improve. Developing new models for different spaces, different needs, different budgets. Investing in water quality research and publishing what we find — because transparency about what's in your water is the first step to fixing it.
MonsoWater isn't just a product company. It's a commitment: every UK family should be able to pour a glass of water and know — not hope, not assume — that it's genuinely pure.
Stop paying for water that isn't pure.
Every day without Pluvia is another day drinking unfiltered tap water. Switch once — save £4,500+ over 5 years.
