Hot Tub Filter for Freeflow Spas

The ProAqua hot tub filter cartridge is used in select FreeFlow Spas models TLX and RLX. Occasionally hot tub manufacturers can vary the filter size for the same hot tub model. Therefore it’s best to confirm that this filter is the same size as the filter in your FreeFlow spa model before ordering to ensure proper fitment.
