Reverse Osmosis (RO) drinking water systems include mechanical filtration to remove particles, carbon absorption and absorption to remove chlorine, taste, odor and chemical contaminants, as well as membrane separation down to 0.0001 microns. RO membranes remove dissolved solids at the ionic level. No other purification system can provide better removal. System provides your family with premium water for drinking and cooking at a fraction of the cost of bottled water. That means no more deliveries, heavy containers, storage problems, spills, or bottle deposits.
