02The signature
“Water, mastered — end to end.”
03The house — since 2006
Twenty years defending the health heritage.
No fear, no vague promises: a Geneva house that measures, installs and services.
The commitment
Defending the health heritage of a home is a craftsman's work: measure first, equip second, service always. The house was built on that order, installation after installation.
2006
Geneva. The first installation fitted by the house.
The last kilometre
Public water is controlled up to the network. The final metres — pipework, tanks, taps — belong to each building. Those are the metres we take charge of: no speeches, just measurements.
“Drinkable is a threshold. Perfect is a standard.”
The technicians
No subcontracting: certified installers, trained by the house, who return every year for servicing. The face you see at the installation is the face you will see again.

A question first?
The house replies in English, Monday to Friday. Support →
09Questions
Straight questions, clear answers.
The rest lives at Support — or on the phone, with a technician of the house.
Is the kit really free?
Yes — the kit, the postage and the analysis are complimentary. We would rather begin the relationship with a measurement than with a speech.
Does installing ANNA require building work?
No. ANNA sits under the sink, with a dedicated tap fitted cleanly by our technicians, in half a day.
And the servicing?
Three cartridges. One motion — under thirty seconds, no tools. The house lets you know when the moment has come.
Does the taste really change?
Water freed of what clutters it recovers a clean, neutral taste — the kind that lets tea, coffee and cooking express themselves.
And if my water is already good?
All the better: the report will say so, figures in hand — and so will we. The house does not install where it is not useful.
