Water Softener Sizing Guide
Which model is right for you? Use the steps below to help guide you in your decision.

All North Star water softeners are built with the same quality and efficiency and are designed to save you time and money.

Step 1—Capacity

Determine the grain capacity of the unit for you. Family size, peak flow rate needs, hardness and iron minerals in water, and desired regeneration frequency, are some of the considerations to use when sizing the proper system. The chart below is a general reference.
