Rainsoft 9590-T Three Stage RO System

rainsoft-9590-system.jpg

The Rainsoft 9590-T 3 Stage RO system featured a 5 micron carbon block pre-filter, a 12 GPD TFC membrane, and a 5 micron granular activated carbon inline post filter, all of which we offer generic non-OEM replacements for. The Rainsoft 9590-T Three Stage RO System uses a carbon block pre-filter 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.
