InLine DI

High quality mixed bed DI cartridge. Both cation and anion resin beds combined into a mixed bed. Typically, this filter was found only in pharmaceutical and other laboratories. Today however, these filters are found in home reverse osmosis systems for control of arsenic, nitrates, perchlorates and phosphates. They are also a favorite of reef keepers and salt water fish enthusiasts. So if you need zero(0) TDS water, you need one of our DI cartridges.
