WATER WITH BENEFITS 532w" sizes="(max-width: 175px) 100vw, 175px" width="175" height="300">
Stay Cleaner and Prevent Dry Skin and Hair
That same film that’s on your shower door ends up on your skin when you have hard water. Soft water does a much better job of rinsing soaps and shampoos to prevent
their drying effects.

Keep Everything Cleaner and Prevent Hard Water Damage
Soft water doesn’t leave scale and scum on your faucets, tubs and shower doors making it much easier for you to keep them clean and prevent hard water buildup that can cause damage.

Protect Your Favorite Clothing and Linens
Hard water is hard on fabrics, wearing them prematurely, and causing fading and brittleness. Soft water can extend the life of your clothes and household textiles by removing the dissolved minerals that create problems.

Reduce Soap and Detergent Use
Use up to 75 percent less detergent and get the same or better cleaning results with soft water on the job.

Reduce Energy Consumption
By preventing scale buildup inside of your water heater, you can make it up to 30 percent more efficient since it won’t have to heat your water through a layer of scale buildup.

Extend the Life of Your Appliances and Plumbing
Your water-using appliances and plumbing stay cleaner, work more effectively and last longer with soft water.

All North Star water softeners are built with the same quality and efficiency and are designed to save you time and money. Which model is right for you? Use the steps below to help guide you in your decision.
