⚠️ IMPORTANT: VERIFY FIT BEFORE ORDERING
Compatibility varies by model and production year. Always confirm your existing cartridge measures 13 5/16″ in length and 4 15/16″ in outer diameter with open ends (2 1/8″ I.D.) before purchasing.

Pro Tip: The C-4326 uses 3 oz. Reemay 2033 media — if your filter housing supports it, the Unicel C-4625 uses the same dimensions with a heavier 4 oz. media for extended service life between cleanings.
