Did you know that conventional reverse osmosis systems typically waste 4-12 gallons for every gallon of R.O. water produced? If you’re looking for a more economical and environmentally friendly way to enjoy top quality drinking water, the H.E.R.O. is a perfect system for you. The H.E.R.O. wastes virtually no water with over 99.9% recovery. Purified water is collected in the storage tank and then rather than sending the un-purified water to the drain, it is recycled back to be used throughout your house.
