Great-tasting beverages start with great-tasting water. Keep your water fresh and your beverages tasting their best with Keurig Water Filter Cartridges. Designed to be used in conjunction with the Keurig Water Filter Handle, these cartridges form an easy-to-use filtration unit that fits inside the water reservoir of your Keurig coffee maker and helps remove chlorine and other impurities from your water, so your coffee, tea, hot cocoa, or any one of hundreds of delicious K-Cup varieties tastes exactly as it should. Keurig Water Filter Cartridges are designed for use with all Keurig Water Filter Handles, and are compatible with nearly all Keurig coffee makers. To keep your beverages at the peak of their flavor, we recommend that you change your Keurig Water Filter Cartridge every 2 months or 60 tank refills, whichever comes first. Like all Keurig accessories, these cartridges are BPA-free and made from the highest quality materials.
