The Unicel 6CH-502 hot tub filter has the larger 2 inch male MPT threads and is used in select Resort Line Spa models by Artesian. Resort Line Spas have also used other-size filters for their hot tubs. Therefore it’s best to confirm that this filter is the same size as the existing cartridge in your hot tub 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.
