Under-sink RO purifier
Drinking water from its own tap. A very fine membrane holds back most dissolved salts.

Under your sink
The unit sits in the cabinet under your sink.
Water in
Your mains or tank water comes in here.
Sediment
Catches sand, rust and silt, so the finer stages last longer.
Carbon
Reduces chlorine, odours and off-tastes.
RO membrane
A very fine membrane that holds back most dissolved salts. What it holds back leaves through the drain line.
Final stage
A last polishing stage for taste, just before the tap.
Tank and tap
Some models keep clean water in a small tank; tankless models make it as you pour. It comes out of its own tap.
Under your sink
The unit sits in the cabinet under your sink.
The service visit
These are the parts we replace at service visits. How often depends on your water and how much you use.
Questions and answers
How is it installed?
It sits in the cabinet under your sink and connects to your water supply and the drain. The treated water comes out of its own tap on your sink or worktop.
What does a service visit replace?
The sediment, carbon and final-stage cartridges, and the RO membrane when it's due. How often depends on your water and how much you use.

Does it send water to the drain?
Yes. What the membrane holds back leaves with some of the water through a drain line. How much differs by model and by your water.
Tank or tankless?
Some models keep treated water in a small tank; tankless models make it as you pour. Ask us which suits your kitchen.
What doesn't it do?
It holds back most dissolved salts, not all, and it treats the water at its own tap, not the tank or the pipes. For less scale across the house, ask about a water softener.
Where are the specifications?
Stages, tank, tap, drain connection, dimensions and power are confirmed on the data sheet for each model. Ask us for it on WhatsApp.
