What filtration performance can I expect from these cartridges?

Poolzilla cartridges use dense pleated media and Dirt-Trap design to capture a wide range of particles. They remove visible debris like leaves and insects, finer sediment and suspended particles that cause cloudiness, and help maintain steady flow for your pump.

• Pleated fabric increases surface area for better dirt capture.
• Dirt-Trap design concentrates contaminants in creases for easier cleaning.
• Helps reduce turbidity and visible suspended particles in the water.
• Maintains higher flow rates even with accumulated debris.

How do I clean and maintain these replacement cartridges?

Routine cleaning keeps cartridges working efficiently and extends service life. Remove the cartridge, rinse with a garden hose, and inspect pleats for stubborn buildup; a filter cleaner soak may be used seasonally. With proper care, expect approximately 1–2 years of service life depending on pool usage and water conditions.

• Rinse with fresh water after heavy use or visible buildup.
• Use a dedicated filter cleaner soak every few months for deep cleaning.
• Inspect end caps and pleats for damage during each cleaning.
• Replace every 1–2 years, or sooner if pleats are torn or deformed.
