Find the part number printed on your old cartridge in the Compatibility tab. If you cannot read it, measure the outside diameter and the length, check both end caps, and compare them with the Specifications tab. A difference of about 1/8 inch is normal; more than that usually means a different filter model. Matching measurements alone do not prove a fit: some of our cartridges share a size and differ in filtration area or end caps.
It replaces R173214, ULTRA-C2, C-9407, FC-0685, 59054100, Aladdin 17525, Baleen AK-8002 and OnCore OC-J16A. The Compatibility tab lists the rest.
It fits the Pentair Clean & Clear CC75 and Pentair Predator 75. Check the model on your filter tank before you order.
No. Excel Filters makes this cartridge in Austin, Texas. It is not made, sold or endorsed by Pentair; we use the name only to show which filters it fits.
Most pool and spa cartridges last one to two seasons, depending on how much the water is used and its chemistry. Rinse the cartridge monthly during heavy use, and replace it when cleaning no longer brings the flow back or the pleats show wear.
First check the part number on your old cartridge against the Compatibility tab: most fit problems come from ordering for a different filter model. If you still have a question, call us at (888) 532-2801 and we will help you find the right cartridge, before or after you order. Returns follow our standard return policy.
