Ultra-fine cartridge filter panels help capture smaller debris inside a compatible robotic cleaner, and this Maytronics version is designed for DX3 and DX4 applications and supplied in a quantity of four using the 9991422-ASSY reference. Fine filtration panels are useful when the cleaning environment calls for tighter debris capture than a more open filter style can provide.

This set has practical value because replacing all four panels together helps maintain even filtration performance across the cleaner rather than mixing old and new cartridges. A properly selected Maytronics replacement helps preserve original fit and contributes to more dependable fine-particle collection.

This type of part is especially useful when existing panels are worn, damaged, or no longer trapping smaller debris effectively. That helps restore the filtration system in a more complete and more balanced way.

Installed in the proper application, these filter panels help support finer debris capture and more dependable overall cleaning results.

  • Ultra-fine cartridge filter panels for compatible Maytronics DX3 and DX4 cleaner applications
  • Supplied in a quantity of four
  • Helps capture smaller debris during robotic cleaning cycles
  • Useful when replacing worn or damaged original panels
  • Improves filtration performance and maintenance confidence
