When it comes to coffee, great taste starts with great water. Braun's charcoal water filter, for use with BrewSense Drip Coffee Makers, removes chlorine, calcium and water impurities that interfere with that rich, savory flavor in your cup of coffee. Easy to install and replace, the filter lets you enjoy pure, fresh-brewed flavor at home. (Braun BrewSense Drip Coffee Maker sold separately.)
