Fil-fresh Robotic Pool Cleaner Filters 4-Pack for Dolphin M400/M500 & Nautilus CC Plus (9991432-R4)

Enhance pool clarity with Fil-fresh 9991432-R4 filters

Fil-fresh offers a practical 4-pack of ultra-fine cartridge panels designed to replace worn or clogged filters in a variety of robotic pool cleaners. While not every model is identical, these panels balance thorough debris capture with long-lasting performance, providing a straightforward option to refresh your cleaning routine without paying OEM prices.

What makes these filters stand out

• Full compatibility range including Dolphin M200, M400, M500 and Nautilus CC Plus (note: not for older Nautilus CC).
• Targeted fit: measuring 10 1/2 x 6 3/8 inches, the panels slide in with minimal effort for quick swaps.
• Ultra-fine filtration paper catches finer sand and sediment, potentially reducing debris in the pool water more than standard fabrics.
• Solid structure: a thick pleated fabric paired with a sturdy plastic frame resists deformation as water flows through.
• Reuse-friendly: easy to rinse with a garden hose and reuse, helping extend overall filter life with proper care.

Real-life use and benefits

Imagine a weekend of swimming with clearer water and less visible grit on the pool floor. The combination of ultra-fine filtration and a robust frame is designed to support consistent filtration, even as the cleaner works through variable debris. While results depend on pool conditions, many users find the panels complement regular maintenance by maintaining better suction and debris handling between cleanings.

Tips to maximize performance

• Swap panels quickly when you notice reduced suction or increased debris buildup in the filter chamber.
• Rinse the panels after use and allow them to dry completely before storing to keep the fabric supple.

Notes on compatibility and care

Before purchasing, confirm that your robot model aligns with 9991432-R4. The 4-pack is designed for Dolphin M200, M400, M500 and Nautilus CC Plus; not for the Nautilus older models. For other brands like Oasis Z5i, Odyssey, Sigma, C3, C4, and Triton variants, check model-specific compatibility.
