Gladon AG75 Replacement Pool/Spa Filter Cartridge (AG75)
The Gladon AG75 is a replacement cartridge filter element designed for select pool and spa cartridge filter housings that use this cartridge style. Replacing a worn cartridge helps restore normal flow, lower filter pressure, and improve water clarity when cleaning no longer brings the cartridge back to performance.
Key Benefits
- Restores filtration performance by trapping dirt, oils, and fine debris in the pleated media
- Helps maintain strong circulation for better heater, salt system, and overall equipment performance
- Improves water clarity and reduces rapid pressure rise caused by clogged or collapsed pleats
Compatibility / Fit Notes (Important)
- Cartridge fit depends on exact dimensions and the top/bottom end cap style (open/closed ends, center opening size, handle, etc.).
- Before ordering, match your existing cartridge by measuring: overall length, outside diameter, and top & bottom opening (and whether either end is closed).
- If your filter uses multiple cartridges, replace the full set for balanced flow and consistent filtration.
When to Replace
- Filter pressure rises quickly even after a thorough cleaning
- Pleats are torn, frayed, or separating
- Core is cracked/collapsed or end caps are swollen/brittle
- Cloudy water persists despite proper chemistry and run time
Cleaning & Care Tips
- Clean when pressure rises 8–10 PSI above your clean starting pressure.
- Rinse pleats top-to-bottom with a hose nozzle.
- Degrease first for oils; descale only after degreasing (never acid-wash an oily cartridge).
- Rotating a second cartridge set reduces downtime and can extend cartridge life.

Maintenance Tips
- Keep skimmer/pump baskets clean—restricted suction can mimic a “dirty cartridge” problem.
- Maintain balanced water chemistry to reduce scale and oil loading on the media.
- If you get frequent algae or heavy debris, clean cartridges more often to avoid crushing pleats and shortening cartridge life.
