373045 Sundance Pleated Filter. This 50 sqft 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.
