The Unicel 5CH-25 hot tub filter with closed top and 1-1/2 inch male threads on the bottom was mainly used in the Elegant, Intrigue and Joli spa models made by MAAX Spas in Chandler Arizona. Those three hot tub model names have also been used by other manufacturers over time for spas that use different filters. Therefore it’s best to confirm that this filter is the same size as the existing cartridge in your MAAX Spa model before ordering to ensure proper fitment.
