Artesian Filter Cartridge (Resort Line)

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.
