The house, at your service.
The answers to the usual questions, a callback whenever you wish — and access to your client area.
01Questions
All the answers, in one place.
Eight questions that keep coming back — and, for the rest, a callback and contact details a little further down.
Is the analysis kit really free?
Yes — the kit, the postage and the analysis are complimentary, with no obligation. The complete journey (steps, timings, laboratory) is described on the Test my water page.
Does installing a purifier require building work?
No. ANNA sits in the cabinet under the sink, with a dedicated tap fitted cleanly by our technicians, in half a day. Nothing else changes in the kitchen.
How does the servicing work?
Three cartridges. One motion — under thirty seconds, no tools. The house lets you know when the moment has come, and your client area shows the calendar of your installation.
Does the taste of the water really change?
Water freed of what clutters it recovers a clean, neutral taste — the kind that lets tea, coffee and cooking express themselves.
How do I meet a technician?
Leave your number in the callback form below: a technician calls you back the same working day [to be confirmed]. After an analysis, your Water Score report also proposes visit dates — arranged on request for international addresses [to be confirmed].
What is the client area for?
It is the service after the installation: cartridge orders at member terms, delivery tracking, servicing calendar and direct contact with your technicians. You sign in with the credentials handed over at installation [to be confirmed].
What guarantees cover the equipment and the installation?
The warranty terms — equipment, fitting, follow-up — are set out in writing with every quotation [to be confirmed — exact durations]. What never changes: a single point of contact, the house, from installation to servicing.
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.
