The Unicel 6CH-945 hot tub filter with the 2 inch course SAE male threads on the bottom was used in select early Jacuzzi J-460 models that used the OEM 6540-498 filter. Due to the range of filters used by Jacuzzi for the J-460 model, it’s best to confirm that it 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.
