ERO 300 3-Stage RO Compatible Replacement Filters

This is a three stage reverse osmosis system. The carbon block pre-filter removes chlorine and small particulates so the RO membrane is not damaged. The carbon block post-filter adds a finishing touch for taste and odor. Find compatible filters below. Due to a discontinued membrane, we recommend switching to the PureValue 5EZ50-RK RO Retrofit Kit for continued use if your tubing is 1/4" in size. This allows for continued use the tank and faucet and for an upgraded membrane to be used for updates in filtration technology. Please check your system as a different retrofit kit may be required.
