Why Dutch households filter their tap water
Dutch tap water meets the legal standards. But those standards don't cover everything researchers find in it. In six minutes: what the measurements show, how reverse osmosis works, why the Osmora Premium then gives minerals back to the water, and what a litre costs you.

What is in your tap water?
Water utilities measure the legal parameters. What falls outside them comes from research — and that research finds traces.
Tap water comes from groundwater and surface water. Both are in contact with farming, industry and sewers. Water utilities take a great deal out, and what comes from the tap meets the standard the law sets.
That standard does not cover everything. For some of the substances researchers find, no drinking water limit exists yet. They are in the reports all the same.
Three groups that keep coming back in the reports
- PFAS — a group of substances that barely breaks down, hence "forever chemicals"
- Pharmaceutical residues — from sewers and farming
- Microplastics — found in tap water and in bottled water
What these figures do and do not say
What follows is measurements, not a verdict on what a substance does. Every figure has a source; they are collected on the sources page.

Why reverse osmosis
A filter jug improves taste and odour. Reverse osmosis works at 0.0001 micron: a completely different scale.
In reverse osmosis, water is pushed under pressure past a membrane that works at 0.0001 micron. Dissolved substances stay on one side, your drinking water comes out on the other. It is the same technique used to make drinking water on board ships.
Then the minerals go back in. You can taste it.
Everyone knows the downside of reverse osmosis: the water ends up bare. The Osmora Premium solves that. After the membrane, a remineralisation step adds calcium and magnesium back. So you get thoroughly filtered water that still tastes full.
The membrane works at 0.0001 micron. Dissolved substances stay on one side, your drinking water comes out on the other. Osmora Premium filter specification
Why FluoFree
Filtration, remineralisation and hydrogen in one appliance. With a membrane and carbon block tested by NSF.
- Remineralisation: calcium and magnesium back after filtration
- NSF/ANSI-tested components: the RO membrane (58) and the carbon block (42)
- Hydrogen enrichment after filtration, in the same device
- Dutch water technology
- One filter change a year; nothing else to do
About the NSF test
NSF tested the RO membrane (NSF/ANSI 58) and the carbon block (NSF/ANSI 42) for material safety. Both passed. This is a component listing covering those two parts.
Filtration, remineralisation and hydrogen: three steps, one appliance on your worktop. Nothing extra to buy, nothing to build in.

Drink truly clean water from £0.14
Per litre, including filter set and electricity. No hauling bottles, no deposit, and remineralised water from your own tap.
Filter set £86.00 / 2000 L
Electricity per litre £0.09
Per litre £0.14
Electricity is our own assumption of €0.09 per litre, not a measured figure; it matches the default budget of €100 a year in the calculator below. The filter price comes straight from the shop.
