Ensure that your Brio dispenser produces consistently clean water with the 3-stage replacement kit for Brio 3-stage cooler dispensers, including CLPOU720UVF3, CLPOU520UVF3, CLPOU730UVF3T, CLPOU730UVF3, CLPOU720UVF3X, CLPOU720UVF3XB, CLPOU430UVF3, and CLPOU530UVF3. The sediment filter reduces dirt, dust, rust, and any other large particulates commonly found in tap water. The pre carbon filter reduces chemicals that effect taste and odor, like chlorine, as well as chemicals that are harder to detect like volatile organic compounds. The final carbon block filter removes any residual tastes and odors to leave your water looking and tasting its very best.
