Valueline RO System Replacement Prefilter and Postfilter Kit
Complete Three-Stage Replacement Set
Filter Kit Details
Component Breakdown
| Sediment Prefilter | 1 × 5 micron spun polypropylene cartridge |
| Carbon Block Prefilter | 2 × activated carbon block cartridges |
| Inline Postfilter | 1 × granular activated carbon (GAC) inline with 1/4" female pipe thread |
| Replacement Interval | Prefilters and postfilter: 12 months | Membrane (not included): 24–36 months |
| Operating Temperature | 40–100°F (4–38°C) typical municipal water range |
| Housing Compatibility | Standard 10" filter housings on Valueline RO systems |
| Installation Note | Transfer existing fittings from old inline postfilter to new unit using Teflon tape |
System Match and Use Cases
This kit is specifically dimensioned for Valueline reverse osmosis systems and provides all prefilter and postfilter cartridges required for one year of operation. The sediment prefilter protects the membrane from particulate fouling, while the dual carbon block prefilters remove chlorine and organic compounds that can oxidize and damage the RO membrane. The inline GAC postfilter connects directly into the permeate line using 1/4" female pipe thread fittings, delivering final taste and odor polishing before the faucet. Note that the RO membrane itself is not included in this kit and typically requires replacement every 2–3 years depending on source water quality and system usage. Ideal for residential point-of-use applications where municipal or well water feeds the Valueline RO platform.
