Key features that drive real value
- Reinforced center cores with extruded PVC construction and round holes for even distribution of stress. This design supports higher debris loading and helps prevent cartridge collapse during heavy filtration, extending time between cleanings.
- Premium filter media—high‑quality polyester keeps up with durable, cleanable filtration and sustained water clarity for longer life.
- Antimicrobial end caps reinforced for strength and treated to repel odor‑causing bacteria and mold. The formulation resists deterioration in salt pools and with high chlorine levels, protecting both the cartridge and your water quality.
- Wider break‑resistant bands keep pleats evenly spaced, minimize flutter from turbulence, and maintain optimum flow for thorough filtration.
- End caps with integrated fittings—molded‑in fittings allow easy installation and removal, eliminating the need for pad adapters that can impede flow and filtration.
- Embossed part numbers for straightforward identification and re‑ordering, so you can keep your pool or spa running smoothly without guesswork.
- 75 sq ft filtration area delivers substantial surface area for efficient dirt capture and longer cycles between cleanings, making it well suited for average to demanding spa/pool setups.
