Rainsoft RO Frequently Asked Questions
Do Rainsoft compatible filters work directly in my Rainsoft system?
Some filters will require a system "conversion kit" be installed first (such as for the Rainsoft Ultrefiner II, Ultrefiner UF22, and Ultrefiner UF50 systems). A retrofit kit pays for itself pretty quickly as it 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 in the future.
