Six-month capacity with simple maintenance

Rated for replacement every six months, the filter handles everyday household demand for clean water and ice. When flow noticeably slows or taste changes, the cartridge has reached its limit and should be swapped.

No additional fittings, tubing or adapters are needed; the cartridge seats directly into the factory filter head. The tool-free design frees up time and avoids the risk of cross-threading or leaks during installation.
