Benefits of Reverse Osmosis Water Treatment in the Home

  • Eliminate up to 99% of dissolved solids, chlorine, fluoride, microorganisms and heavy metals such as barium, cadmium, chromium, lead and mercury from your water. Use RO purified water for drinking, cooking, and ice for improved taste superior to bottled water.
  • Designer chrome-plated faucet adds an attractive feature to your kitchen while dispensing filtered water right to your sink - making it convenient to use for drinking, cooking, making beverages and ice, pets, and watering houseplants.
  • System can be used to supply filtered water to a refrigerator ice-maker/water-dispenser by inserting a branch tee fitting (sold separately) between the post filter and the faucet.
  • Systems are equipped with automatic shut-off valves to eliminate waste by closing the feed line when the tank is full.
  • Save Money & Help the Environment! Consumers spend billions each year on bottled water, sending 3 billion pounds of plastic into landfills. Use of a reverse osmosis system for your home's drinking water eliminates your need to buy expensive bottled water, and reduces your carbon footprint and personal waste.

Benefits of Alkaline Mineralization

  • Restores calcium and magnesium minerals (ions) removed during the reverse osmosis process to create pH-balanced, alkaline mineral water on tap.
  • Enhanced flavor for great tasting water, coffee, and beverages.
Clean Fresh Water from the Tap

6 Stages of Filtration for Clean, Great-Tasting Water

Home RO Alkaline Water Treatment System Drinking Water Filter

  • Stage 1 - Sediment Filter
    A 5-micron filter removes sediment including dirt, sand, rust, grit, and other suspended matter from the water. This protects the rest of the filtration stages and equipment from damage and clogging due to buildup of sediment.
  • Stage 2 - Carbon Filter
    A carbon block filter removes chlorine, chemicals, and objectionable tastes and odors from the water. This filter also protects the membrane from exposure to chlorine, which would irreparably damage the membrane.
  • Stage 3 - Carbon Filter
    A second carbon block filter is an extra layer of filtration to ensure the removal of any remaining chlorine, chemicals, and flavors – ensuring great tasting water and maximum membrane protection.
  • Stage 4 - AMI RO Membrane
    Made-in-USA RO membrane removes TDS from the water, including arsenic, barium, cadmium, chromium (hexavalent), chromium (trivalent), copper, turbidity, fluoride, lead, radium 226/228, and selenium while washing the rejected contaminants down the drain.
  • Stage 5 - Carbon Polishing Filter
    The coconut shell carbon filter gives one last stage of filtration to perfect the flavor of the water. The water is filtered as it flows from the storage tank, directly before being dispensed from the faucet.
  • Stage 6 - Alkaline Minerals Cartridge
    In-Line Mineral Cartridge to alkalize the water, raising pH, enhancing the flavor, and enriching water with natural minerals In-Line design with ¼” threaded female in/out connections and quick-connect fittings installed.
