-
Reinforced center cores with extruded PVC construction provide even stress distribution and higher debris loading, helping prevent cartridge collapse under heavy filtration demands and extending the time between cleanings.
-
Antimicrobial end caps—also reinforced and with integrated mesh for added strength—are formulated to repel odor-causing bacteria and mold, while resisting deterioration in salt pools and high-chlorine environments.
-
Premium filter media uses durable polyester that maintains cleanability and filtration efficiency, promoting clearer water and sustained performance over time.
-
Sharp pleat folds and unique synthetic fiber construction minimize bridging, allowing dirt to penetrate deep into the pleats for improved flow and easier cleaning.

Wider, break-resistant bands keep pleats evenly spaced, reducing flutter and maintaining optimal flow even in turbulent housings.
-
End caps with integrated fittings provide easy installation and removal, eliminating the need for PAD adapters that can impede filtration and reduce flow.

Embossed part numbers simplify identification and re-ordering, helping you stock the right replacement when you need it most.
