Gladon WFSG12525 Replacement Pool/Spa Filter Cartridge (WFSG12525)
The Gladon WFSG12525 is a replacement cartridge filter element designed to restore strong water flow, clear filtration, and reliable circulation in compatible pool or spa cartridge filter systems. Replace your cartridge when pleats are torn, the core is cracked, the end caps are deteriorating, or when cleaning no longer restores normal pressure and flow.
Key Features
- Replacement cartridge element for cartridge-style pool/spa filters
- Helps improve water clarity by trapping dirt, oils, and debris in the pleats
- Durable filter media and reinforced internal core for dependable performance
- Designed for easy rinse-clean maintenance to extend service life between replacements
Compatibility / Fit Notes
- Designed to fit select cartridge filter housings that use this cartridge style
- Always match by your current cartridge measurements (overall length, outer diameter, and top/bottom opening style)
- If your filter takes multiple cartridges, replace the full set for balanced flow and more consistent filtration
When to Replace
- Filter pressure rises quickly after cleaning
- Visible tears, frayed pleats, collapsed media, or a cracked core
- End caps are swollen, brittle, or separated
- Cloudy water persists even with correct chemistry and run time
Cleaning & Maintenance
- Rinse pleats top-to-bottom with a hose nozzle after shutdown and pressure relief.
- For oily buildup, soak in a cartridge cleaning solution, then rinse thoroughly.
- For scale (calcium), use a dedicated descaler after degreasing (never acid-wash an oily cartridge).
- Keep a second cartridge on hand to rotate—this reduces downtime and extends overall cartridge life.

Maintenance Tips
- Clean cartridges when pressure rises 8–10 PSI over your clean starting pressure.
- Rinse after heavy debris events and maintain proper run time—filters can’t clear water without circulation.
- Keep water chemistry balanced to reduce oils and scale that shorten cartridge life.
- Never run the system without the cartridge installed—this can damage equipment and send debris downstream.
