    How It Works

    The CU-A4 is a multi-layered filter system that provides protection against a wide range of contaminants while retaining healthy minerals.
    Stage One: A Polypropylene (PP) sediment filter (5 microns) removes larger particles like rust, sand, and dirt
    Stage Two: A Ultra Filtration Filter contains hollow fiber membrane technology with a pore size of just 0.01 microns.
    Stage Three: The third stage is a hybrid Kinetic Degradation Fluxion (KDF) Media and activated charcoal (GAC) filter. The KDF media sets the CU-A4 apart from other systems by providing control of particularly problematic contaminants including chlorine, hydrogen sulfide, iron, lead, nickel, chromium, cadmium, calcium, aluminum, mercury, arsenic, and other compounds.
    Stage Four: The last fine activated carbon (GAC) filter provides final polishing before the filtered water is delivered to the faucet, removing any possible residual chlorine, tastes or odors.
