Do I Need to Use a Water Softener in Naperville?

A water softener is likely worth the investment. Naperville tap water is rated “moderately hard” (130 to 145 mg/L), drawn from Lake Michigan water via DuPage Water Commission. Hard water can leave cloudy glassware, stiff laundry, and crusty mineral buildup on fixtures, and that scale can shorten the life of water-using appliances. A properly sized softener can help protect them. Learn how ion-exchange water softeners work.
