How much do Rainsoft water filters cost? Rainsoft propriety water filters can be very expensive. We offer a variety of high-quality (yet low-cost) alternatives for Rainsoft water filters. By installing the filters and conducting routine system maintenance yourself, you'll see substantial savings. 

 

NOTE: Some filters require a system "conversion kit" be installed first (such as the Rainsoft Ultrefiner II, Ultrefiner UF22, and Ultrefiner UF50 systems). A retrofit kit allows you to keep using your current Rainsoft tank and faucet, but by installing a new manifold (component that holds the filters), you're able to use less expensive Rainsoft-compatible filters going forward. Our customer support team is happy to answer any questions you might have about this process. 877-377-9876 Mon-Friday, 8 am to 5 pm CT.
