Specifications

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.
