Your water may look clear. But it could contain impurities, like lead, mercury, and chloramine.

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.
