The drinking water stage
An under sink unit feeding a dedicated faucet at the kitchen tap.
Some of what it takes care of
The last of the taste that the whole house stages leave behind
Dissolved solids that the whole house stages do not touch
Ice, coffee and everything you cook in water
And when the assessment finds something this stage does not do, you get pointed at the one that does.
The system
Reverse osmosis works at one tap rather than across the whole house. It is the point of use answer for the unregulated compounds Charlotte Water reported in 2025, including PFPeA, PFBA and PFHxA at low parts per trillion, for which no federal drinking water standard exists.
What it costs
Free with the system
There is no standalone price to compare, because it is not sold that way. The RO rides free with the whole home system, inside the one number that page shows. If drinking water is your whole situation, the assessment sorts out what that looks like.
Get Your Free Water AssessmentThe tap you drink from deserves its own stage.
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 assessment.
Next to your main kitchen tap, a small faucet of its own. The box lives in the cabinet under the sink.
That is an assessment conversation, not a menu item. Start there and the answer comes with a number in writing.
