Filbur Quad Pack Replacement Filter Cartridges for Hayward SwimClear C3020, C3025 and C3030 | FC-6425
The Filbur FC-6425 is a complete four-cartridge replacement set for compatible Hayward SwimClear pool filters. Each cartridge provides 81 square feet of filtration area and is sized to replace the Hayward CX580XRE cartridge element. The four-pack format allows all cartridges in a compatible filter tank to be replaced together for balanced filtration performance and consistent water flow.
These replacement cartridges are designed to capture dirt, debris, and other contaminants as pool water passes through the filter. Replacing worn or damaged cartridges can help restore filtration performance, improve water clarity, and reduce unnecessary restriction within the circulation system.

- Confirm the filter tank model and existing cartridge dimensions before ordering.
- Do not select a replacement cartridge set using filtration area alone. Cartridge length, diameter, end-cap openings, and filter model must also match.
- This listing includes replacement filter cartridges only. The filter tank, manifold, air-relief components, O-rings, and other filter parts are sold separately unless specifically stated otherwise.

Maintenance Tips
- Turn off the pool pump and relieve all filter pressure before opening the filter tank.
- Clean cartridges periodically with a garden hose using a gentle spray pattern between the pleats.
- Avoid using a pressure washer, as excessive pressure can damage the filter media.
- Replace all four cartridges together when possible to maintain balanced water flow through the filter.
- Inspect the tank O-ring and internal manifold components while the filter is open.
- Replace cartridges when the media becomes damaged, cleaning no longer restores normal filter pressure, or water clarity begins to decline.
