Outstanding design that boosts filtration and longevity
- Reinforced center cores: Extruded PVC cores with round holes distribute stress evenly, preventing collapse under heavy debris loading and extending time between cleanings.
- Premium filter media: Durable polyester media provides sustained filtration efficiency and lasting water clarity, even with regular use.
- Antimicrobial end caps: End caps are reinforced and treated to repel odor-causing bacteria and mold, helping protect your system in salt and high-chlorine environments.
- Wider break-resistant bands: Strengthened bands keep pleats evenly spaced, reduce flutter from turbulence, and maintain optimal flow through the cartridge.
- Sharp pleat folds: Innovative synthetic fiber construction prevents bridging, allowing dirt to penetrate deep into the folds for improved filtration and easier cleaning.
- End caps with integrated fittings: Molded-in fittings simplify installation and removal, eliminating the need for PAD adapters that can impede flow.
- Embossed part numbers: Clear identification for quick, accurate re-orders and minimal downtime.
- Salt and chlorine tolerance: Formulated to resist deterioration in saltwater pools and high-chlorine spas, delivering reliable performance in modern water systems.
