The Unicel 6CH-925 hot tub filter has been used in select Gulf Coast Spas models. Gulf Coast Spas also used a couple of other filter sizes in their hot tubs over the years. Therefore it’s best to confirm that this filter is same size with the same threads as the existing cartridge in your Gulf Coast 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.
