How does our SoftnKlear water softener work? Raw water is forced through the ion exchange resin that is charged with salt ions. The hard water, including iron and manganese, is attracted to the ion exchange resin. An equal amount of sodium ions are bumped off into the water supply. Thus making your water soft and not harsh on your skin, appliances, or pipes. Give your experts at AquaKlear Filtration LLC a call for your new water softener system today!
