Reverse osmosis at the kitchen tap.

It puts a second, smaller faucet at the sink, matched to your existing hardware. The main tap still handles dishes. The second one is for drinking, cooking and rinsing produce.

Why it matters in this county

How much this is worth to you depends on which system serves your house. Woodway reports average total dissolved solids of 584 mg/L, with a range of 314 to 808, and average sodium of 185.93 mg/L. Waco reports sodium of 16.0 to 17.9 mg/L. Those are two very different starting points for the water coming out of a kitchen tap.

How the stages work

• A pre-filter stage, roughly the size of a large fridge filter.
• The membrane itself, which is the stage that acts on dissolved solids.
• A post-filter stage that puts minerals back, so the water does not taste flat.

It fits under the sink

The unit is small enough to leave most of the cabinet usable. It can go in on its own, or at the same time as a whole-home setup, which is the simpler job of the two.
