RO-10 Three Stage RO System


The RO-10 is a Pure-Tel RO system that uses standard filter cartridges and membrane. Replace the pre- and post- filters annually and the membrane every 2-3 years. See below for compatible replacement filters.


Due to a discontinued membrane, we recommend switching to a RO Retrofit Kit, which allows for continued use of the tank and faucet in addition to upgrades in filtration technology. If your system features 3/8" tubing to the faucet, replace with the Goldline-50-RK RO Retrofit Kit. A John Guest Stem Reducer may be required. For systems with 1/4" tubing to the faucet, replace with the PureValue 5EZ50-RK RO Retrofit Kit. Please check your system as a different retrofit kit may be required.
