If you include the measurements of the filter you are looking for, along with either a photo or description of the 2 ends of the filter, we can provide you with a link to the filter you need.

Many times the filter installed in a spa can be different for the same model name - it all depends on which filter canister is installed in the spa at the time of production - so it is best to measure the old filter length, diameter to get the correct replacement cartridge.
