Hayward CX880XRE Filter Cartridge
Hayward OEM number • 106 sq ft • 7″ OD × 25.5″ long
CX880XRE is Hayward's number for this cartridge, not a part you have to buy from Hayward. The filter itself is a 106 square foot cartridge measuring 7 inches across and 25.5 inches long, and Pleatco, Unicel, and Filbur all build it. If you read CX880XRE off an old cartridge or found it in your manual, any of the numbers below drops into the same housing.
Fitment notes
3-inch top and bottom openings. Hayward SwimClear C4020, C4025, C4030 (4 cartridges required, 425 sq ft total).

Frequently Asked Questions
What filter replaces the Hayward CX880XRE?
The PA106 replaces it directly, and so does every cross-reference for it: C-7488, FC-1226. All of them are the same 106 sq ft cartridge at 7" outer diameter and 25.5" long. Buy whichever is cheapest at the time with solid recent reviews.
Is the Hayward CX880XRE the same as the PA106?
Yes, physically the same filter. Hayward CX880XRE is an OEM number, meaning it is the code Hayward put on the cartridge that shipped with the equipment. Hayward does not manufacture cartridges. Pleatco, Unicel, and Filbur do, and they sell the identical part under their own numbers at a lower price. Match the dimensions against your old cartridge before ordering and you are covered.
Do I have to buy the Hayward version?
No. Nothing about the housing requires an OEM-branded cartridge, and the warranty on your equipment is not voided by using an aftermarket filter that meets the same spec. The reason to buy OEM is convenience, not performance. The reason not to is price, which is often a meaningful gap for an identical part. What matters is that outer diameter, length, and end-cap style all match.
What size is the Hayward CX880XRE?
7 inches in outer diameter, 25.5 inches long, with 106 square feet of filter media. Both measurements need to land within about an eighth of an inch, and the end caps have to match so the cartridge seats correctly when you close the lid. Measure your old one rather than trusting a number that has worn off the label.
