Drinking water at a glance
An under-sink system with its own kitchen faucet — a final, finer step for the water you drink and cook with.
Step 1 of 3 · How RO works
Reverse osmosis uses your water pressure to push water through a membrane with extremely small pores. Clean water passes through; dissolved solids and many other substances are held back and rinsed down the drain.
Works with your whole-home system
Your whole-home tanks treat every tap. RO adds one more layer of treatment at a single dedicated faucet.
Pre-filters and post-filters
Carbon stages before and after the membrane help protect it and polish taste.
Some water goes to the drain
That's how the membrane rinses itself — every RO system does this.
Step 2 of 3 · Your two options
Option 1 · Tankless
Compact, no storage tank — makes filtered water on demand.
Option 2 · With storage tank
Keeps filtered water ready in a small pressurized tank.
