Rainsoft Ultrefiner UF10 Three Stage RO System
If you're needing filter replacements for the Rainsoft Ultrefiner UF10 Three Stage RO System, we carry high-quality generic replacement filters and filter replacement bundles. The Rainsoft Ultrefiner UF10 RO system was used prior to 2013 and allowed for generic replacement filters. The Ultrefiner UF10 featured 3 stages with a 5 micron polyspun sediment pre-filter, a since discontinued 10 GPD CTA membrane, and a 5 micron carbon block as a post filter. This 3 stage Rainsoft RO system uses a sediment pre-filter to reduce sediment particles before the membrane filters out impurities larger than .001 microns. The carbon block post filter treats for taste and odor. Because the required membrane has been discontinued, we highly recommend converting to the 5EZ50-RK to keep your old tank and spout with the same high quality water you expect.
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.
