ERO 200 Three Stage RO System


The ERO 200 by GE (General Electric) is a discontinued three stage reverse osmosis system. The sediment pre-filter removes large particulates to preserve the RO membrane. The carbon post filter treates for chlorine, tastes and odors. 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.
