CWW-1C Three Stage RO System
The CWW (Clean World Water) CWW-1C 3 stage RO system uses a sediment pre-filter to reduce particles larger than 5 microns before the RO membrane filters out impurities larger than .001 microns. The carbon block post filter treats for taste and odor. You can find and order all your filters at once in our replacement kits below.
Due to a discontinued membrane, we recommend switching to the PureValue 5EZ50-RK RO Retrofit Kit for continued use. 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.
