The Resin Filter cartridge is the most powerful and finest filtration. The filter cartridge features granulated activated carbon media. The filter is used to prevent hard water scaling and staining while eliminating chlorine, taste, odor, smell and heavy metals from the water.

  • Superior Water Softener Scale reduction filter
  • Removal of Calcium, Magnesium and Iron
  • High efficiency grade filter
  • Ideal for Hard water
  • Suitable for Big Blue Housings

The Resin filter cartridge reduces hardness and scale deposits in water, leaving all the benefits of soft, gentle, clear water. Convenient, compact design means that softened water can be provided at point-of-use.

Hard Water contains dissolved minerals in the form of Calcium (Ca), Magnesium (Mg), and Iron (Fe).  Removal of these minerals is accomplished by softening the water through an ion exchange process using water softener resin.  As the water flows through the mineral tank of the water softener, the dissolved minerals become attached to the resin, creating soft water.

GAC Carbon filtration is the best form of filtration for chemical extraction due to the longer and more thorough contact time the water has with the carbon, which in turn provides an extremely comprehensive method of chemical removal.

Fits all standard 20″ big blue filter housing with easy installation/replacement.
