Save money with high-quality compatible filter replacements for the Rainsoft 9596 Four-Stage Reverse Osmosis System. The Rainsoft 9596 features four filtration stages including 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, lead, fluoride, and more, before the membrane filters out impurities larger than .001 microns. The Granular Activated Carbon (GAC) post filter treats for taste and odor. **The Rainsoft 9596 RO system was used circa 2000 and allowed for generic replacement filters. 

 

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. These proprietary replacement filters can become very costly over time. Installing a retrofit kit is a great alternative. Learn more about how the Ultrefiner II can be upgraded/retrofitted with a "conversion kit". Conversion kits to generic non-OEM replacement filters are available.
