- Works with a wide range of popular Dolphin robot models, reducing the need for multiple filter types.
- Easy to clean and maintain with no special tools required.
- Affordable price compared to manufacturer replacement filters.
- Solid build quality with lightweight yet sturdy plastic construction.
Cons
- Not compatible with Dolphin Nautilus CC Pro or CC Supreme models, limiting its use for newer variants.

The Ulticor Ultra Fine Filter Basket is an aftermarket replacement designed specifically for a wide array of Dolphin robotic pool cleaners. It is an ideal choice for pool owners who already own compatible models such as the Dolphin S50, S100, Active 10/15, Echo, T15, T25, Proteus DX3, Saturn, Cayman, Escape, and others. This basket is not intended for the Nautilus CC Pro or Supreme versions, so buyers should verify compatibility before purchasing.
What sets this filter apart is its microfiltration technology, which captures even the tiniest debris particles. In real-world use, this translates to a noticeably cleaner pool with clearer water, as fine dirt, sand, and pollen are effectively trapped. The basket is easy to rinse and clean every four to six weeks, maintaining peak performance without hassle. Users report that it fits snugly and works reliably cycle after cycle.
The design is straightforward: a white, lightweight plastic basket measuring roughly 9x5x7 inches. Build quality feels solid for an aftermarket part, though it may not have the exact finish of an OEM component. The inclusion of installation tips for older Active 10 or S50 units (which may need a small internal plastic piece removed) shows attention to compatibility details. A video guide is available upon request to assist with that adjustment.
Potential drawbacks are mostly centered on fitment limitations. Owners of Nautilus CC Pro or Supreme will need to look elsewhere. Also, the need to modify older robots could be a minor inconvenience for those not comfortable with simple DIY tasks. However, for the vast majority of compatible users, installation is plug-and-play.
Overall, the Ulticor Ultra Fine Filter Basket offers excellent value for money. It delivers superior filtration at a lower price than official replacements, while covering a wide range of popular Dolphin models. If you own one of the listed robots and want to keep your pool sparkling clean without breaking the bank, this filter is a smart buy.
Pros
- Ultra-fine filtration traps even tiny particles for superior water clarity.
- Easy numbered installation system reduces setup time and guesswork.
- Washable and reusable design offers long-term value and eco-friendliness.
- Broad compatibility with many Dolphin and Maytronics robotic pool cleaner models.
- Sturdy build quality withstands regular use and cleaning without tearing.
Cons
- May require more frequent cleaning than standard filters due to ultra-fine mesh trapping more debris.
- Not compatible with all Dolphin models; double-check compatibility before purchase.
- Some users may find the initial fit slightly tight on certain cleaner baskets.
The Henkgo ultra-fine filter panels are a direct replacement for the OEM part 9991467-R4, designed specifically for Dolphin robotic pool cleaners. These pleated cartridge filters are ideal for pool owners who want to maintain sparkling water without frequent skimming. They fit a wide range of models including the S200, Active 20, Proteus DX4, M600, and many more, making them a versatile upgrade for most Dolphin owners.
Standout features include the ultra-fine pleated material that captures sand, gravel, leaves, and even microscopic debris. In real-world use, these filters dramatically improve water clarity compared to standard mesh filters. The numbered panels (1-4) simplify installation: remove in order and replace in reverse, so even first-time users can swap them in minutes. The filters are also washable with a garden hose, retaining their shape and effectiveness after repeated cleanings.
Build quality is reassuringly sturdy. The pleated material holds up well under water pressure and regular cleaning. Each panel measures 9 x 8 x 2.1 inches and weighs just over a pound, making them lightweight yet durable. The white color blends inconspicuously into most pool cleaner baskets. Compatibility is extensive, covering over 25 Dolphin and Maytronics models, which adds significant value for households with multiple cleaners or future upgrades.
One potential drawback is that the ultra-fine mesh may clog faster than coarser filters, especially in heavily debris-laden pools. This means more frequent cleaning sessions, but the ease of rinsing offsets this inconvenience. Additionally, while compatibility is broad, it is not universal, so buyers should verify their specific model before ordering. The initial fit on some cleaner baskets might feel snug, but this ensures a secure seal.
Overall, the Henkgo ultra-fine filter panels offer an excellent balance of performance, durability, and affordability. They deliver professional-grade filtration at a fraction of the OEM cost. For Dolphin pool cleaner owners seeking clearer water and less maintenance, these filters are a smart investment. The simple installation and reusable design make them a practical choice for any pool season.
Buying Guide: What to Look for in a Leaf-Focused Replacement Filter
Filtration Mesh Size and Leaf Capture
For leaf debris, you need a filter that balances openness to allow water flow with fine enough mesh to trap shredded leaves and small fragments. Fine mesh baskets (around 180 microns) catch sand and silt but can clog quickly with leaves. Microfiltration technology, like that used in the Ulticor Ultra Fine Filter Basket, offers a middle ground: it captures tiny particles while allowing larger leaf pieces to be trapped without blocking flow. Look for filters labeled “ultra-fine” or “hyper-fine” that specify leaf capture capability.
Compatibility with Your Robot Model
Not all filters fit every robot. The Ulticor basket works with many Dolphin models but not all (e.g., Nautilus CC Pro). The Chasing Hyper-fine basket is specific to Hydro3, Hydro3S, Hydro4, and Hydro4SE. Sponge filters for cordless cleaners like PoolMr and Ray are model-specific. Always check the compatibility list before buying. A mismatched filter can leak debris or fail to seat properly, reducing cleaning efficiency.

Ease of Cleaning and Maintenance
Leaf-heavy pools require frequent filter cleaning. Basket-style filters (like the Ulticor) are easy to rinse with a hose, but you may need to remove large leaves manually. Sponge filters (like the csyls 5-pack for WYBOT A1) can be squeezed clean, but they wear out faster. Pleated cartridge filters (Henkgo 9991467-R4 panels) are numbered for easy replacement and can be sprayed clean. Consider how often you are willing to maintain the filter; some designs allow quick top-load access (Chasing) while others require opening the robot.
Durability and Build Quality
Filters that handle leaves repeatedly need robust construction. Reinforced stitching on mesh bags (SIFFOI XL bags) prevents tearing when full of wet leaves. UV- and chemical-resistant materials (Chasing basket) ensure longevity in harsh pool conditions. High-density cotton sponge (Wowewk for PoolMr) resists deformation. A durable filter saves you money over time by reducing replacement frequency. Cheaper filters may fray or lose shape after a few cleanings.
Final Thoughts
After reviewing these eight replacement filters, the Ulticor Ultra Fine Filter Basket Compatible stands out for Dolphin owners who want a balance of fine filtration and leaf-handling capacity, while the Chasing Hyper-fine Filter Basket is the top choice for Chasing Hydro series users who value easy top-load cleaning and hyper-fine mesh. Both options are built to capture leaves and keep your pool water clear. Remember to match the filter to your specific robot model and clean it regularly for best performance in 2026.

Frequently Asked Questions
How often should I replace my robotic pool cleaner filter for leaves?
It depends on usage and leaf load. For heavy leaf debris, check the filter after each cleaning cycle. Most manufacturers recommend replacing sponge filters every 1 to 2 months and basket or cartridge filters every 3 to 6 months. In 2026, many filters are washable and reusable, extending their life if cleaned promptly.
Can I wash and reuse these leaf filters?
Yes, most of the filters reviewed here are washable. Rinse basket filters with a garden hose, squeeze sponge filters clean, and spray pleated panels. Avoid using harsh chemicals or bleach. Let them air dry completely before reinstalling. Proper care can make them last several seasons.
Which filter is best for large leaves versus fine debris?
For large leaves, a mesh bag like the SIFFOI XL (18.5″ x 16.5″) holds big loads and prevents clogs. For a mix of leaves and fine dirt, the Ulticor ultra-fine basket or the Henkgo pleated panels offer balanced filtration. If your robot is a Chasing Hydro series, the hyper-fine basket catches both leaves and silt effectively.
Are these replacement filters compatible with all robotic pool cleaners?
No, each filter is designed for specific models. Always verify compatibility before purchasing. For example, the Ulticor basket fits many Dolphin models but not Nautilus CC Pro or Supreme. The csyls sponges are only for WYBOT A1. Check the product description or contact the seller if unsure.
