Some under sink water softeners come with additional features such as a built-in filter or an indicator for salt levels. These features can add convenience and improve the overall performance of the unit.

5. Consider Installation and Maintenance

Before making a purchase, it is important to consider how easy it is to install and maintain the under sink water softener. Some units may require professional installation while others can be easily installed by following instructions provided by the manufacturer.
