Ensure that your Brio dispenser produces consistently clean water with the 4-Stage Replacement Kit for Ultrafiltration Cooler Dispensers. Four powerful filters are compatible with Brio 4-Stage Ultrafiltration Cooler Dispensers, including CLPOU520UVF4, CLPOU320WUVF4, CLCTPOU720UVF4, and CLPOU520UVF4BLK. 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 ultrafiltration membrane is rated at 0.1 microns and meticulously filters out health-impacting contaminants like E. coli. The final post-carbon stage removes any residual tastes and odors to leave your water looking and tasting its very best.
