When you install a US4 high capacity under sink water filter, you're providing your family with 35,000 gallons of pure, clean drinking water.

The US4 water filter is a sealed system which means you don't have to change or replace cartridges. After 35,000 gallons, you replace the entire system. It's long reach, chrome faucet is designed to access filtered water easily and exclusively.
