  • NOTE: This filter will NOT work with the Spa Frog Mineral Purifier System. Spa Frog requires an 8 inch long filter. 
  • The Mineral Harmony and Amerse Brand sanitizer sticks WILL WORK with this filter, if the spacer stick is adjusted (cut) to correct length as to not block water flow at base of the filter where it threads on.
  • Used in the first generation of Softubs in the late 80's through the late 90's.
  • A good solution when your old-style suction cover breaks apart. The threads on these match up to the older Hydro-Air suction wall fittings (1-1/2 mpt).
