The Unicel 6CH-45 hot tub filter is used in select Master Spas models and the following Freedom Spas models: Statesman, Lexington, Enterprise, Aristocrat and Franklin. Both hot tub manufacturers have used different filter sizes for many of their models over the years, and therefore it’s best to confirm that this filter is the same size as the existing cartridge in your spa model before ordering 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.
