Kenmore® 350 Water Softener

Where to Buy

The Kenmore 32,000 Grain Water Softener is the ideal fit for households of 1-4 that are looking for a reliable and effective system to provide soft water. Designed with intuitive technology, the Kenmore 350 offers cost savings that other models can’t match. IntelliSoft® technology keeps track of your water usage over time and regenerates beforehand, using only what it needs in salt and water. This helps you save money on costs needed to keep your system operating at peak efficiency—and ensures you’ll never run out of soft water.

Designed with advanced electronic controls, you can easily monitor water flow, salt level in the tank and more with the Kenmore 350.

This system will help reduce mineral stains, calcium buildup in appliances and promote healthier skin and hair. Soft water also helps you save money on soap and detergent, keeps clothes bright and soft, and allows your water-using appliances to run more efficiently with fewer maintenance issues.
