Before Ordering

Please check your existing system size, filter layout and cartridge requirements before ordering. This product is a replacement filter cartridge only and does not include the full whole-house filtration system.

When to Replace

Replacement frequency depends on household water usage, local water quality and system flow rate. Follow your system instructions and replace the cartridge when due, or sooner if flow rate or taste changes noticeably.

Note: Water quality varies by location. For specific concerns, consider independent water testing before and after filter replacement.
