Don't be fooled by flashing lights or interchangeable "specialty" filters. The most important part of your reverse osmosis drinking water system is the membrane. Our Platinum RO unit features a state-of-the-art Thin Film Composite (T.F.C.) Membrane that actually filters water at the molecular level, making it virtually impossible for anything but pure H20 to pass through to the other side and into your glass. Another important fact you may not hear elsewhere is that the RO membrane is very delicate. Factors such as chlorination, water hardness, and the presence of bacteria may damage the system if not accounted for. Call today for your free, comprehensive, in-home water analysis and let the professionals at Ecolo Ionex make sure your RO system is right for you.
