ZeroWaste® Reverse Osmosis System

The ZeroWaste® Reverse Osmosis System with its patented design wastes no water where other systems waste as much as 4 or more gallons for every 1 gallon of drinking water produced. This system revolutionized the industry; the patented ZeroWaste® Reverse Osmosis System is the first RO system that does not waste water by returning unused water from the system back to the home's hot water supply. Reverse Osmosis reduces particles down to the molecular level—the same process used by major bottled water companies. The process of Reverse Osmosis reduces salts and other impurities, giving you a high-quality, great tasting water. This system is 100% efficient, as no water is lost to drain in the production of the Reverse Osmosis Water. 

The ZeroWaste® Reverse Osmosis Filtration System uses a 4-Stage Filtration based upon separate treatments.

  • Sediment - A 5 Micron Sediment Filter traps sediment and other particles like dirt, silt and rust which affect the taste and appearance of your water.
  • Carbon - A 5 Micron Carbon Block Filter reducing Chlorine, Chloramines and other materials that cause bad taste and odor.
  • 24 GPD Membrane - A Semipermeable Membrane removes TDS, Sodium and a wide range of contaminants such as Chromium, Arsenic, Copper, and Lead.
  • Carbon In-Line (GAC) - A high quality In-Line Granular Activated Carbon (GAC) Final Polishing Filter is used after the water storage tank to remove any remaining chlorine or other chemicals that cause bad taste or odor before being dispensed.

Important Information -
  • Requires a 110-volt electrical outlet independent from the garbage disposal.
  • Not recommended for use on homes equipped with tank-less water heaters.
  • Not recommended for use on homes equipped with a backflow prevention on the hot water heater.
  • Must be installed a minimum of 25 Pipe Feet from water heater.
  • A Non-Switched outlet is needed to provide power to the pump.
  • Not compatible with the 75 GPD Membrane.
