A Reverse Osmosis System (RO) provides clear, clean tasting water by removing impurities in your water that give it a bad taste. RO processes water at the molecular level by filtering water through a series of filters. The filter squeezes the tap water against a special membrane that forces the Total Dissolved Solids (TDS) down the drain and allows the high quality drinking water to be stored in a storage tank to be used at your convenience.
