7 Stage Pro RO/DI Systems - Perfect for almost any water condition, but if you have contaminants that use excessive amounts of DI resin, the 7 Stage RODI system is the ideal choice. It uses cation and anion single bed resins that give you added control and cost savings over traditionally used mixed bed resins. Most water supplies tend to exhaust either the positively or negatively charged resin more quickly than the other, and by separating the standard mixed bed resin into single beds, you are no longer throwing away good deionization resin.
