Put the final refreshing touches on your water with the Brio stage 3 coconut carbon replacement filter. A replacement filter that's compatible with the Brio clpou320uvf3, clpou720 uvf3, clctpou320uvf3, and clctpou720uvf3 water coolers, the stage 3 post carbon filter reduces any lingering impurities in water by using activated coconut carbon, a form of carbon that's been processed to produce a large surface area with microscopic pores. This type of filter is incredibly efficient at meticulously adsorbing chlorine, volatile organic compounds, and any remaining particulates. The Brio stage 3 filter - the final one in a thorough 3-stage filtration process - ensures your water looks great and tastes fantastic.
