The Unicel 4CH-940 hot tub filter has a closed top and non-standard 1-1/4 inch course SAE threads on the bottom made to fit select Dimension One Spa models. Dimension One Spas have used several different size filters for the same hot tub models depending on year and features. Therefore it’s best to confirm that this filter is the same size as the filter in your Dimension One Spa model before ordering to ensure proper fitment.
