Rainsoft 9596 4-Stage RO Compatible Replacement Filters

If your Rainsoft 9596 Four-Stage Reverse Osmosis System is due for filter replacements, we offer high-quality compatible filters for this system (see below). Purchasing proprietary filters for the Rainsoft 9596 RO system are expensive, must be purchased directly from a Rainsoft authorized dealer, and have no real benefits over standard RO systems.

Note: If your reverse osmosis system is from 2013 or newer, it most likely is the Ultrefiner II RO system which requires proprietary Rainsoft filters and our “compatible filters” will not work.

Update Recommendation: To reduce costs, save water, and produce purified water faster, consider converting your Rainsoft system to the PuROTwist Retrofit Kit (PT4000T75-RK). This conversion kit allows you to use PuROTwist filters with your existing Rainsoft faucet, tank, and tubing. Start saving on replacement filters today!
