The vast majority of dissolved impurities in modern water supplies are ions such as calcium, sodium, chlorides, etc.


The deionization process removes ions from water via ion exchange. Positively charged ions (cations) and negatively charged ions (anions) are exchanged for hydrogen (H+) and hydroxyl (OH-) ions, respectively, due to the resin's greater affinity for other ions.

The ion exchange process occurs on the binding sites of the resin beads. Once depleted of exchange capacity, the resin bed is regenerated with concentrated acid and caustic which strips away accumulated ions through physical displacement, leaving hydrogen or hydroxyl ions in their place.


* DI filter treated dissolved mineral salts from water by Ion-exchange resins and produces a high purity water without scale buildup.

* Size : 9” / 11” / 13”
* Service Life : 6 Month
  (Service life of De-Ionization filter could be changed depending on raw water condition.)
