125 sqft Sundance Pleated Hook Filter. This filter is not a reproduction like many on-line stores carry. This filter is a certified O.E.M filter straight from the Sundance factory and is engineered with a proprietary filter chamber that is designed to pull the correct amount of water through your pump in-order to produce crystal clear water and elimate pump failure un-like many other reproductions or non-Sundance Filters.
**This filter fits all Sundance Spas designed to attach onto a Filter Hook that is installed in the filter well of your spa. The length of this filter is 18″-18.5″ and the diameter is 8.5″
**Please make sure to check your filter measurements to ensure proper fit
