These units soften water using a process called “ion exchange” to remove dissolved hard water minerals such as calcium, magnesium, iron and manganese. It then filters the water by running it through a media that retains the contaminants while allowing the water to pass. Some units also utilize a reaction called adsorption, in which the atomic charge of the carbon and other media causes the contaminants to abandon their bond with the water and chemically attach to the media.
