Sales Channel: Wholesale

NOTE: NOT FOR SALE OR USE IN CA The all new patented ZeroWaste Point-of-Use Reverse Osmosis System is the first ever that wastes no water. Comparable systems typically waste up to 4-12 gallons of RO water for every gallon produced. This highly efficient Watts RO system provides better-than-bottled water quality for residential applications. It features a 4-stage system of filtration: Sediment filter that removes particulates down to 1 micron; carbon block filter that removes chlorine, taste, and odors; an advanced TFC membrane that rejects impurities down to 1/10,000th of a micron, and an activated carbon final filter serves as a final polish to remove any trace residuals. This system reuses rinse water (no waste). It includes 50 gallon per day TFC membrane, upgraded Watts top mount faucet, and 3-gallon storage tank.


  • Generates zero waste water because reuses rinse water
  • Four-stage reverse osmosis filtration system
