The Brita Filter's activated carbon and ion exchange resin work together to filter ordinary tap water and turn it into healthier, great tasting drinking water. The Riviera pitcher is NSF and Water Quality Association certified to reduce chlorine (taste and odor), copper, sediment, 98% lead, benzene, and more. A feature that sets the Riviera filtration pitcher apart from others is its SMART technology, a built-in electronic indicator automatically notifying users when to change the filter. For optimum performance, change the filter every 2 months or 40 gallons. Filter replacement is essential for the product to perform as represented. The filter change indicator contains a non-replaceable sealed battery designed to last 5 years, depending on usage. After 5 years the pitcher is still functional, but the electronic filter change indicator will eventually stop working. Designed with a 64-ounce capacity, this pitcher makes it easy to get the eight daily recommended 8-ounce glasses of water. Its streamlined body allows the pitcher to fit in most refrigerator side doors. Included in the box are the pitcher, a flip-top, easy-pour lid, and 1 filter. This model is available in a choice of colors to better accessorize with any kitchen decor.
