The Unicel 8CH-66 hot tub filter with 2 inch male MPT threads on the bottoms is compatible with select Master Spa models that use the 8 inch outside diameter by 9-1/4 inch tall cartridge. Due to the range of filter sizes Master Spas has used in its hot tub models over the years, it’s best to confirm that this Unicel cartridge is the same size with the same threads as the existing cartridge in your Vita Spa model to ensure proper fitment and performance.

How long should Unicel hot tub filters last?
While most hot tub filters need to be changed every six to twelve months, Unicel brand filters are made with REEMAY premium trilobal filtration media that delivers 45% more surface area over standard rounded filter fibres and can last up to two years or more, depending on your level of use and cleaning routine.
