Cartridges and housings for Culligan whole-house and under-sink filter systems, original and compatible.

  • Cartridge size. Standard housings take a cartridge about 2.5 in across and 10 in long. Heavy-duty housings take 4.5 in cartridges, 10 or 20 in long.
  • Micron rating. Lower numbers trap finer sediment and clog sooner: 20 to 30 micron for sand and rust, 5 micron for fine sediment.
  • Media. Pleated and spun cartridges remove sediment; carbon cartridges reduce chlorine taste and odor.

All types: water filters and cartridges.
