Rainsoft 9596 Four Stage RO System
If you're needing filter replacements for the Rainsoft 9596 Four Stage RO System, we carry high-quality generic replacement filters and filter replacement bundles. The Rainsoft 9596 RO system was used circa 2000 and allowed for generic replacement filters. The Rainsoft 9596 featured 4 stages with a 5 micron polyspun sediment pre-filter, a 5 micron carbon block filter, a 22 GPD TFC membrane, and a 5 micron granular activated carbon inline post filter. The Rainsoft 9596 RO system uses sediment and carbon block pre-filters to reduce sediment, chlorine, and chlorine by-products before the membrane filters out impurities larger than .001 microns. The Granular Activated Carbon (GAC) post filter treats for taste and odor.
Note: If your Rainsoft reverse osmosis system is from 2013 or newer, it most likely is the Ultrefiner II. The Ultrefiner II requires proprietary filters that must be purchased from a Rainsoft dealer. Conversion kits to generic non-OEM replacement filters are available.
