The Unicel 4CH-950 hot tub filter has a unique 1-1/4" course SAE threads with a closed top that is used by select Dimension One and Saratoga Spas models. These hot tub manufacturers had different filter sizes that varied for the same hot tub model based on the year of manufacturer and features. Therefore it’s best to confirm that this filter is the same size as the filter in your Dimension One or Saratoga Spa model before ordering to ensure proper fitment.
