About This Item
The Unicel C-7470 is a 7000 Series 80 sq. ft. replacement filter cartridge precision-engineered for the Pentair Clean & Clear Plus 320 and Waterway Crystal Water 325 cartridge filter systems. With 170 pleats of 4 oz. Reemay® 2040 spun-bonded polyester media, it delivers the filter surface area and pleat density your system was designed to run — maintaining water clarity without compromising flow.
⚠️ IMPORTANT: 4-Cartridge System — Replacing the Full Set?
The Pentair Clean & Clear Plus 320 and Waterway Crystal Water 325 systems each require four (4) cartridges for a complete replacement. This listing is for one (1) cartridge. If you are replacing the full set, see the Unicel C-7470-4 4-Pack Set.

Pro Tip: Before ordering, confirm your filter's model number on the label or owner's manual — the Clean & Clear Plus line includes multiple sizes (CCP320, CCP420, CCP520), each requiring a different cartridge. Measure your existing cartridge: 20" long, 7" OD, 3" ID at both ends confirms C-7470 is your correct match. Replacing all four at once maximizes system performance and ensures even flow across all cartridges. Ready to replace the full set? See the Unicel C-7470-4 4-Pack Set.
