Reverse osmosis drinking water
A dedicated stage under the kitchen sink, on its own faucet. The water you drink and cook with gets taken further than the whole house stages take it.
What it takes care of
And when the call turns up something this stage does not do, you get pointed at the one that does.
What the whole house stages leave behind in the glass you drink.
The minerals and salts that carbon and softening do not touch.
Everything you make with water at the kitchen tap.
Dealing with something else?
The tankless RO. A small box in the cabinet under the sink.
The system
One stage in a small box under the sink. Tankless, so no storage tank eats the cabinet, and it feeds its own faucet at the counter. Filter changes come on the schedule in your setup notes, and that is the whole routine.
The RO can be added as a third stage to the whole home system, which softens and filters the water for the rest of the house.
What it costs
From $599 installed
Under-sink RO drinking water is from $599 installed. It can be added to the whole home system, and your exact number comes on a 5-minute call, in writing, before anything is ordered.

Your main kitchen tap stays as it is. The drinking water faucet sits beside it and the unit lives in the cabinet below.
The tap you drink from deserves its own stage.
Good to know
Water is pushed through a very fine membrane that lets water through and holds back much of what is dissolved in it. What is held back is rinsed to the drain.
It is the stage that goes furthest, which is why it is used for drinking and cooking water rather than the whole house.
Showers, laundry and toilets do not need drinking water. Putting reverse osmosis on one faucet keeps the system small and puts the treatment where you actually drink.
The rest of the house is handled by the whole home system.
Older systems store treated water in a pressure tank under the sink. A tankless unit makes water as the faucet runs, so the cabinet keeps most of its room.
The faucet sits beside your main tap and does not change how the main tap works.
Filter changes come on a schedule, written into your setup notes when the system goes in.
That is the whole routine. There is no tank to drain and nothing to adjust.
Questions
Anything else, ask it on the call, and the answer comes back with your number.
The whole house stages handle what you feel and smell everywhere. The water you swallow is held to a tighter bar, and what this stage takes out of yours specifically is part of the call.
Next to your main kitchen tap, a small faucet of its own. The box lives in the cabinet under the sink.
That is a question for the call. Under-sink RO is from $599 installed, and the answer comes with a number in writing.
It is a small box with no storage tank, so most kitchen cabinets keep the bulk of their room.
On the schedule in your setup notes, which are written for your system when it goes in.
