Before ordering, compare your existing cartridge's measurements and connection details with the specifications below. Compatibility depends on the filter fitted to your spa, so the Legend or Passport model name alone should not be used to confirm the correct replacement.

  • Length: 9-3/4 inches.
  • Top: 2-1/8-inch opening.
  • Bottom: 1-1/2-inch male MPT thread.
  • Filter media area: 45 square feet.

Compatible replacement references

  • Pleatco PFF50P4.

Check the diameter, length, top opening and threaded bottom against your current cartridge before purchasing. Use the replacement references together with those measurements to confirm fit for your Freeflow spa.
