Performance and filtration design

Designed for steady, efficient cleansing, the cartridge features 30‑micron precision filtration. A strengthened trilobal fiber structure enhances particle capture while preserving a stable water flow, helping to minimize pressure buildup and reduce the need for frequent maintenance.

  • 30-micron precision filtration for clear water
  • Upgrade: trilobal fiber with 40% more branches for better capture
  • Uniform fiber distribution supports consistent flow and reduced clogging

Durability and lasting value

Durability is built in through a thickened 5 oz fabric, sturdy ABS end caps, and an integrated support core. This combination is designed to bolster structural stability under pressure and extend service life by up to 30% compared with standard cartridges, depending on pool usage.

  • Thickened 5 oz fabric and strong ABS end caps
  • Integrated support core for rigidity under pressure
  • Potentially longer service life than conventional cartridges

Fit, care, and maintenance tips

To ensure optimal performance, confirm the fit against the listed dimensions before purchase. After installation, rinse the cartridge gently and monitor water flow and pressure to determine when a replacement is due. This approach supports easier upkeep and a more enjoyable swimming season.
