The Advanced Water Filtration System is Moen’s best water filtration system. Moen’s Advanced Water Filtration packs a similar performance of multi-stage carbon filtration into a single-stage design if you're looking to improve at-home water quality. The system removes over 30 known water contaminants while also improving the taste, color, and clarity of your drinking water—all while reducing the frequency and quantity of replacement filters to keep your system running at its best. Pair this system with a Moen Sip™ drinking water faucet or 3-in-1 water filtration pulldown kitchen faucet to customize your filtration system and get the style and functionality you desire. An LED indicator light on the unit lets you know when it’s time to change the filter, ensuring your water is always clean and fresh tasting. By utilizing at-home water filtration, you also can cut back on plastic bottle use, which is better for your wallet and the environment. The filter is backed by Moen’s Warranty, for your long-term peace of mind.
