The Unicel 8CH-502 hot tub filter has a v-groove semi-circular handle on the top and 2 inch male MPT threads on the bottom and fit Vita Spas that use the OEM filter PVT 50WH. Vita Spas has used several different filter sizes in its models and series over the years. Therefore 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.
