The Watts WQCGAC11 Kwik Change GAC Cartridge is designed to fit Watts Kwik Change Reverse Osmosis Systems. Changing a filter has never been easier! The WQCGAC11 is color coded blue so you know exactly which old cartridge it replaces!
This GAC (granular activated carbon) filter is the last stage of filtration in the WQC4 RO system. It polishes the water to ensure the best tasting and highest quality water. Cartridge is 11" long. Should be replaced every 12 months.
**Please note, even though the Watts Premier RO replacement cartridges look the same as these filters they will NOT fit your system. **
