Dolphin Filter Cartridge M400 M500 M4 M5 Mesh Filters (Ideal for leafy pools)

Genuine Dolphin M-Series Mesh Filter Cartridge Kit – M400, M500, M4, M5 

Genuine Maytronics Dolphin Mesh / Spring Filter Cartridge Kit – ideal for pools with leaves and larger debris.

The Maytronics 9991433-ASSY Mesh Filter Kit is designed for compatible Dolphin M-Series and Supreme robotic pool cleaners, including the popular Dolphin M400, M500, M4 and M5.

These mesh filters are ideal for leafy pools and situations where your Dolphin regularly collects larger debris. The open mesh design allows good water flow and assist wth Wall climbing, while capturing leaves and other larger material.

Ideal for Leafy Pools & Larger Debris

Choose these mesh filters if your pool commonly collects:

• Leaves
• Larger debris
• Insects
• Organic material
• General everyday pool debris

The mesh design is particularly useful during periods of heavy leaf fall, when finer filters can fill or restrict water flow more quickly.

IMPORTANT – Not Recommended for Fine Sand or Silt

These are NOT the best filters if your main problem is fine sand, dust or silt.

The mesh material is designed primarily for larger debris. Very fine particles may pass through the filter and return to the pool.

If you have fine sand, silt or very fine debris in your pool, choose our Ultra-Fine Dolphin Filters instead.

Selecting the correct filter for your pool conditions can make a significant difference to your Dolphin's cleaning performance.
