About This Item

The Pleatco Ultra ULTRA-C2 is a premium 75 sq. ft. replacement filter cartridge engineered for Pentair Clean & Clear and Predator filter systems. Combining PurePleat™ construction, Point Bonded Fabric, and a Free Flow Core in a single cartridge, the ULTRA-C2 delivers an upgrade in filtration performance over the standard Pleatco Advanced equivalent — with precise OEM-matched dimensions that drop straight into your existing housing without modification.

⚠️ IMPORTANT: Pleatco Ultra Upgrade — Replaces PAP75
The ULTRA-C2 is the Pleatco Ultra upgrade for the standard Pleatco Advanced PAP75. It is dimensionally identical and fits the same Pentair filter housings — you get the same precision fit with the added performance benefits of PurePleat™ construction and Free Flow Core technology.

Pleatco Ultra Features

  • Fits most major pool equipment manufacturers and brands.
  • Combines three performance technologies into a single replacement cartridge:
    • PurePleat™ — engineered pleating that prevents bunching and drives dirt capture to the outer edges, making the cartridge easier to rinse clean.
    • Point Bonded Fabric — manufactured for uniform pore structure and dimensional stability, delivering consistent direct-capture filtration throughout the cartridge's life.
    • Free Flow Core — an open-center core design that maximizes the space available for water to reach more filter fabric faster, reducing operating pressure on the system.
