This 125 square foot replacement cartridge is designed exclusively for Sundance spa systems. Measuring 19 inches in length by 8.5 inches in diameter, it features a 2.5-inch open hole on one end that slides over the mounting fitting and secures with a nut, while the opposite end has a 2.5-inch nipple that inserts into the plumbing connection.
This cartridge serves as an excellent upgrade from the older dual-filter configuration that included the main filter, faceplate, and toilet paper roll style filter combination.
We recommend this single large-capacity filter as a superior replacement for the two-filter setup. The smaller cartridge in the original dual system tends to clog quickly, which commonly triggers FLO1 or FLO error codes on your control panel.
