Rainsoft Ultrefiner II Three Stage RO System
The Rainsoft Ultrefiner II is Rainsoft's latest Reverse Osmosis system and requires proprietary filters that are only available from a Rainsoft dealer. This results in the replacement filters that are typically very expensive. If your Rainsoft reverse osmosis system is from 2013 or newer, it most likely is the Ultrefiner II.
