The Aqua-Pure 3M Under Sink Water Filter System Aqua-Pure AP-DWS1000 Under Sink Dedicated Faucet Water Filter System helps reduce particulate, chlorine taste and odor, lead, turbidity, parasitic protozoan cysts, volatile organic compounds (VOCs) and methyl tert-butyl ether (MTBE) that may be in your drinking water. This system connects easily under the kitchen sink and incorporates an advanced dual stage carbon-block filtration process to help provide cleaner, clearer better tasting drinking water filtration on demand. It is ideal for drinking (water, coffee, tea, baby formula, etc.) as well as for cooking. Its universal system design is effective for use in both chlorinated (municipal) and non-chlorinated (well water) systems. The innovative Sanitary Quick Change (SQC) design allows for fast and easy cartridge change-outs without having to contact the filter media or without the need for tools. In many filtration applications, carbon is often the preferred media of choice to absorb certain impurities and one of the most powerful absorbents available. Carbon is highly effective due to the vast surface area contained within a small footprint. One pound of carbon contains a surface area of approximately 100 to 125 acres and can absorb an extremely wide range of substances which may be in drinking water. Filter Specs: 0.6 gpm/2.27 lpm flow rate, 625 gallon/2,366 liter capacity, 1/4" push-in connection fittings, 25-125 psi/172-862 kPa pressure range, 40-100F/4.4-37.8C. The AP-DWS1000 System includes everything needed for most installations, including: a polished chrome dedicated faucet, quick-connect fittings, an attached mounting bracket, shroud and tubing. Also included is a built-in shut-off valve that allows for changing the Sanitary Quick Change filters without shutting off the water supply. Tools required for installation: drill, adjustable wrench, #8 gauge fastening screws appropriate for mounting surface, Phillips head screwdriver, razor knife or tube cutter. To maximize system performance and efficiency, regularly scheduled maintenance including replacement of the filter cartridges at the required interval, at the rated capacity, or sooner if a reduction in water flow occurs is required. Cartridge should be changed at least every 6 months. Filter life is dependent on actual use and incoming water quality.
