Built to OEM dimensions for Hayward SwimClear C4520, CX875RE, and SwimClear C4520 cartridge filter systems, this replacement matches the original cartridge geometry, end-cap style, and media surface area — without the OEM markup.

Every cartridge is manufactured in our Austin, TX facility, ships free, and is backed by the Excel Filters Perfect Fit Guarantee on its listed cross-references.
The XLS-719 4PACK replacement cartridge is engineered for Hayward and built for dependable day-to-day filtration performance. Each cartridge is sized at 7" diameter x 25 1/2" length, with Open End top and Open End bottom end caps for direct-fit installation with no housing modifications.
Measure your old cartridge cap-to-cap. A variance of ⅛" is normal — anything larger likely means a different housing model.
