Think of it as a water-bottle vending machine built into your house, with a second faucet (color-matched to your existing one) just for the water you actually drink and cook with. Your regular faucet still handles the dishes; this one is for drinking, cooking, and washing produce.
Reverse osmosis is a point-of-use step. It sits at the kitchen tap and treats only the water you drink and cook with, rather than the whole house, which is why it is the piece people add when they want the drinking water treated to a finer level than a whole-home system is built for. For most homes it is also the upgrade that makes the clearest difference in how the water tastes.
The unit is about the size of an Xbox, takes up almost no under-sink space, and looks clean. It's included in both flagship bundles, a near-automatic yes because it's inexpensive to add while we're already installing your whole-home system.
The dedicated drinking-water faucet comes in four finishes, so it fits right in with the rest of your kitchen hardware. No upcharge games, just tell us which one you want.
