Maytronics Dolphin Ultra Fine Filter Cartridges, Set of 4

These are the genuine Maytronics 9991432-R4 ultra fine filter panels, sold as a set of four, for a wide range of Dolphin robotic pool cleaners. Ultra fine panels trap the fine dirt, silt and small particles that coarser filters pass straight through, which is what leaves the water clear rather than just leaf free.

Fit

The set fits the Dolphin Supreme M4, M5, M200, M400 and M500, Liberty Wave 65, Wave 90, C3, C4, Oasis Z5, Triton Plus, Nautilus Plus and Nautilus CC Supreme. Each panel measures 10-1/2 in. by 6-1/4 in.

Keeping the robot working

Clogged or torn panels are the most common reason a Dolphin loses suction and starts leaving dirt behind. Panels change out in a minute, so a fresh set gets the cleaner back to full performance, and having four means you can replace the lot or hold spares.
