The Aqua Flo High Efficiency Reverse Osmosis system (H.E.R.O) produces crystal clear water with improved efficiency. With Hydrotech’s innovation and ingenuity has lead to a break through Reverse Osmosis system which produces little to no waste! This is comparable to the conventional R.O systems which can waste up to 12 gallons of water for every gallon of R.O water it produces. Instead of dumping the rejected water down the drain, The rejected water is instead recirculated into the cold water supply line where it can be used for washing and cleaning.
