We do, but only as a small part of the system. Using reverse osmosis for your whole home is not efficient and extremely expensive, with the maintenance costing up to $100 per month or more. The process wastes a lot of water and energy. Also, reverse osmosis drinking water, while clean, is not optimal as a reverse osmosis membrane can’t distinguish between “good” and “bad” and removes all the mineral out of the water. For this reason, reverse osmosis water is actually acidic and can flush minerals out of your body. At the same time, reverse osmosis is the best way to clean water, so we use it as one step only for the drinking water used, followed by six extra stages and a remineralization process, producing the healthiest, best tasting water possible.
