Whole-house water filter cartridges

Point-of-entry and big blue–style housings need the right length, diameter, and micron rating—not just a similar-looking cartridge. Search by system model or the OEM number on the filter you’re replacing; we list what our data ties together so you can verify against your installed hardware.

  • Model page: cartridges matched to your system or housing SKU.
  • Cartridge page: which systems use that part number.
  • Double-check dimensions and rating with what’s in the sump.
