All the benefits of reverse osmosis but with a water saving membrane. This new technology can save 1-3 gallons of water for every gallon produced. The system reduces dissolved salts, solids, and impurities by use of reverse osmosis technology. Sediment filtration removes dirt, sand, gravel and larger items in the water. Carbon filtration improves the taste and odor of the water and even removes chlorine, sediments, and volatile organic compounds (VOCs).
