The Unicel 7Ch-40 hot tub filter is compatible with select Coleman and Vita Spas that used the OEM 100433 and 3301-1019 filters. Due to the range of filter sizes used by Coleman and Vita Spas, it’s best to confirm that this Unicel cartridge is the same size with the same threads as the existing cartridge in your hot tub 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.
