The problem
Clean at the waterworks doesn't mean clean in your glass.
PFAS: the “forever chemicals”
From pans, packaging and industry, they have long since found their way into groundwater and drinking water. They practically never break down – and only since January 2026 has there been a limit value at all.
The last few metres are down to you
The waterworks only guarantees the quality up to the house connection. Nobody is responsible for old lead and copper pipes in the building – except you.
Germs love standing water
Dead-end pipes, water heaters, two weeks' holiday: germs multiply in standing water. The first glass afterwards comes from exactly that pipe.

The solution
Two stages under the sink: first pollutants, then germs.
The Fusion filters your water twice, right before the tap: the Active stage adsorbs pollutants, the Nano membrane stops microorganisms.
- Active: 3,000–5,000 l, change every 4 months
- Nano: 5,000–7,000 l, change every 6 months – 99.999% germ reduction
- Quick coupling: cartridge change without tools
What the two stages hold back
Bacteria, germs and legionella
The certified 0.1 µm hollow-fibre membrane (ASTM F838-15A) retains 99.999% of microorganisms.
Chlorine and off-flavours
The activated carbon stage adsorbs odours and off-flavours – for fresh, neutral-tasting water.
Heavy metals such as lead and copper
The adsorbent effect of the activated carbon binds and reduces heavy metals from old pipes.
Pesticides, pharmaceuticals, hormones and PFAS
Organic compounds – from pesticides and pharmaceutical residues to PFAS – are reduced in the Active stage.
Microplastics
Anything the activated carbon doesn't bind is stopped by the 0.1 µm membrane at the latest – even the tiniest plastic particles.

Frequently asked questions
Who is better off with the Fusion than with a single-stage filter?
For anyone who wants to reliably rule out germs as well as pollutants: families with small children, old buildings with old pipes, households with immunocompromised people – or anywhere legionella is an issue.
How often do I change the cartridges?
The two stages have different lifespans: Active every 4 months (3,000–5,000 l), Nano every 6 months (5,000–7,000 l). With the quick coupling, the change takes just minutes – without tools.
Will the Fusion fit under my sink?
The double housing measures a compact 227 × 69 mm (830 g) and fits under practically any kitchen sink – mounted between the angle valve and the tap, with a wall bracket if required. Good to know: with the quick-coupling set, the adapters extend the housing by approx. 7 cm each at the inlet and outlet.
I rent my home – will that work?
Yes. Installation requires no drilling, and the filter can be removed without leaving any trace when you move out.
How do I know the germ filtration works?
The Nano membrane is certified to ASTM F838-15A and achieves a germ reduction of 99.999% – the filtration is mechanical, not chemical.
Do minerals stay in the water?
Yes. Neither the activated carbon nor the 0.1 µm membrane removes dissolved minerals such as calcium and magnesium.
Two are better than one. Literally.
Pollutants and germs – from today, both stop under your sink.
