Brita Pitcher Water Filter Cartridge, 3-Pack is specifically designed for use in all Brita pitchers. These cartridges play a vital role in enhancing the quality and taste of your drinking water. They reduce the presence of chlorine, which can affect the taste and odor of your tap water, and effectively lower levels of copper and mercury, two common contaminants found in water sources. To maintain optimal performance, it is to replace the filter cartridge approximately every 40 gallons of water, or roughly every two months. This ensures that the filter continues to provide clean and great-tasting water. Using Brita pitcher filters is a convenient and cost-effective way to enjoy cleaner and healthier drinking water. These filters are easy to install and remove, making the maintenance process hassle-. Model Number: 35503
