Hardness is removed by a process called “ion exchange.” Hardness-causing particles and debris are positively charged. The water runs through DRF’s resin system, which has millions of negatively charged sites. As the water flows past these sites, calcium, iron and magnesium attach to the sites and are “bumped off.” This results in water that will not harm your appliances, cloud your shower door and help with the quality of your laundry.
