- Affordable price compared to manufacturer replacement filters.
- Solid build quality with lightweight yet sturdy plastic construction.

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.

The Fiitzn Ultra Fine Filtration Basket is a replacement filter designed for a wide range of Dolphin robotic pool cleaners, including models like the S50, Active 15, Echo, Nautilus CC, Encore, E10, E20, Proteus DX3, Solo, and Advantage. This part (9991460-R1) is ideal for pool owners seeking an affordable, high-performance alternative to the original filter. It is especially suited for those who want to improve water clarity by trapping fine particles without sacrificing cleaning efficiency.
The standout feature of this basket is its microfiltration technology, which captures small debris while allowing larger particles to pass through. This design prevents the filter from clogging quickly, ensuring consistent suction and longer cleaning cycles. In real-world use, this means less downtime for rinsing and more effective pool maintenance, even in dirty conditions. The basket maintains strong performance over weeks of use before needing a quick rinse.
Build quality is solid thanks to the ABS plastic frame, which resists cracking and deformation under pressure. The filter layer is securely supported, reducing the risk of tearing during operation. Installation is straightforward: it fits exactly like the original part, so no modifications or adapters are needed. Rinsing every 4-6 weeks keeps it working optimally, and with proper care, the basket can last 2-3 years, offering excellent value.
One potential drawback is that in extremely dirty pools, the filter may need more frequent rinsing to maintain flow. Additionally, the package includes only one basket, so owners of larger pools might need to buy a second. Also, while compatibility is broad, it does not cover every Dolphin model, so double-checking the list is wise. These are minor trade-offs for the price and performance.
Overall, the Fiitzn Ultra Fine Filtration Basket delivers on its promise of efficient fine debris capture and durability. It is a smart upgrade or replacement for Dolphin pool cleaner owners who want to keep their water crystal clear without breaking the bank. The combination of microfiltration, sturdy construction, and broad compatibility makes it a reliable choice for routine pool care.

Buying Guide
Filtration Efficiency
The primary job of a filter basket is to capture debris. Look for ultra-fine mesh options, such as 50-micron filters, which trap even microscopic particles like sand and algae. Models with microfiltration technology prevent clogging by letting fine debris pass through while trapping larger items. This keeps your cleaner running efficiently for longer periods.
For pools with heavy debris loads, consider baskets with spring-loaded bottoms that collect leaves without reducing suction. The Ulticor Ultra Fine Filter Basket Compatible and the Ultra-Fine Filter Basket Part No. 9991460-R1 are excellent choices for fine filtration.
Compatibility
Not all filter baskets fit every Dolphin model. Verify that the basket matches your specific cleaner model, such as the S50, Active 10, Nautilus CC, or Explorer series. Many aftermarket options list compatible models, but double-check the part number (e.g., 9991460-R1 or 9991458-R1). Some baskets require removing a plastic piece in older robots, so read the product details carefully.
If you have a newer model like the Active 20 or M600, the Gearwiz Ultra Fine Filter Basket Compatible is designed specifically for those units. For broader compatibility, the Ultra-Fine Filter Basket Part Number 9991460-r1 fits many popular models.
Durability and Build Quality
A filter basket should withstand chemicals, UV rays, and regular cleaning. Look for ABS plastic frames that resist cracking and warping. High-quality mesh materials last 2-3 pool seasons with proper care. Washable designs save money over disposable filters. Rinse every 4-6 weeks for optimal performance.
The Ultra-Fine Filter Basket Part 9991460-r1 from REEPLAR features a sturdy ABS frame and ultra-fine filters that last up to 3 years. Similarly, the Fiitzn Ultra Fine Filtration Basket Compatible offers durable construction with easy cleaning.
Ease of Cleaning
Large filter baskets should be easy to remove and rinse. Top-loading designs are particularly convenient, as you can empty debris without flipping the cleaner. Some baskets include multiple filter panels that can be replaced individually, extending the basket’s life. Look for models with quick-release mechanisms and washable mesh.
For a complete solution, consider the 2 Set Ultra Fine Filtration Basket for Dolphin, which includes replacement panels. The Poolzilla Pool Cleaner Ultra-Fine Filter Basket is also easy to clean and maintain.
