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.

Helpful Filter Information

Not all filters have the same replacement schedule. Replace the RO membrane filter every two years. Replace all other filters every 6-12 months. Help keep your system sanitary by never using filters longer than 12 months, except the RO membrane filter, regardless of how much water you use.

Filter Replacement Schedule

We’ve taken the guesswork out of replacing your filters. Begin a filter replacement cycle by replacing all filters on your system (Filter Kit "YSM"). The following year, or sooner if recommended by the manufacturer, replace all filters except the RO membrane (Filter Kit "YS"). Repeat this cycle by following the helpful diagram below.
