    New UltraPure IEX clear refillable cartridge filter containing custom blended mixed bed ion exchange resins, with indicator dye, for water deionization and TDS reduction.

    Unlike most mixed bed ion exchange resins, our filter provides a true indication of filter media exhaustion. Why? Ion exchange resin manufacturers typically attach dye to only one resin component (anion or cation) while our resin has dye bound to both.

    Ultrapure IEX ion exchange resins are used for applications where extremely high water purity is required, such as pharmaceutical manufacture and semiconductors, and is manufactured to ensure exceptionally low levels of total organic carbon (TOCs) leaching into the RO water.  Incorporated as a post Reverse Osmosis filter, 99.99% pure water is achievable. We use the media in all our drinking water reverse osmosis systems, as well as high end saltwater/reef aquarium systems. The water quality, after ion exchange, approaches 18 MOhm-cm, the highest water purity achievable without distillation.  The resin is particularly effective for the removal of TDS at startup, due to TDS creep, a common problem with tankless RO systems. UltraPure IEX is well suited for the water quality requirements of saltwater and reef aquarium enthusiasts, or anyone desiring ultrapure water.


    A one-to-one volume mixture of a hydrogen form strong acid cation resin (purple colored) and an hydroxide form type 1 strong base anion resin(blue colored). UltraPure IEX utilizes a pH indicator dye in the cation and anion component that changes color from purple/deep blue to amber as the resin exhausts. UltraPure IEX is intended for use in applications where a color indication of resin exhaustion is desired. UltraPure IEX is supplied ready to use with the cation component in the hydrogen form and the anion component in the hydroxide form.
