Coral Single-Stage Under Counter Water Filter System Performance

Drinkable? We can top that.

Your water may look clear. But it could contain impurities, like lead, mercury, microplastics, and chloramine. Wielding 3 stages of filtration, the Coral Three-Stage Filter System reduces those contaminants and more. Have peace of mind knowing the water you drink flows through a sediment filter, a pre-carbon filter, and a carbon block filter.

This easy-to-install water filter system is certified to reduce over 75 contaminants—particulates, chemicals, turbidity, bad taste and odors, and more. The Coral UC300’s filters attach neatly under the sink to preserve your precious storage space. Its elegant, chrome drinking water faucet installs easily through a separate 7⁄16" hole on your sink. Enjoy cup after cup of healthier, better-tasting water while reducing single-use plastic water bottle waste.
