Hydrotech 4VTFC9G-PB (1240300-00) 4-Stage RO Replacement Filters

This 4 stage RO system uses sediment and carbon pre-filters to reduce sediment, chlorine and chlorine by-products before the 9 GPD membrane filters out impurities larger than .001 microns. The carbon post filter treats for taste and odor. Due to a discontinued membrane, we recommend switching to the PuROTwist PT4000T50-SS-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.
