Replacement Filter Cartridges
Match the number on your Coleman or Maax spa cartridge, then confirm its diameter, length and end caps. The choices below use verified cartridge numbers where an exact housing model is unavailable. Check the pack quantity carefully: a bulk pack contains spare cartridges and does not indicate how many your spa uses.
Match your Coleman / Maax filter housing to the right replacement cartridge.
No cartridges match these filters.
