More Details on Our Top Picks
Ultra Fine Filtration Basket Compatible with Dolphin Robotic Pool Cleaners
This ultra-fine filtration basket stands out for its ability to trap larger debris while allowing fine particles to pass, helping prevent clogging in a way that enhances overall cleaner performance. Compared with the Ultra-Fine Filters Compatible with Dolphin Nautilus CC Plus, this basket’s durability and compatibility with a broad range of Dolphin models make it a more flexible choice for owners with multiple or varied cleaners. Its ABS plastic frame ensures long-lasting use, but it requires rinsing every 4-6 weeks to maintain optimal function. If maintenance frequency isn’t an issue, this basket offers a reliable, cost-effective solution that can last 2-3 years with proper care.
Pros:- Effective at trapping larger debris and preventing clogging
- Durable ABS plastic frame ensures long-lasting use
- Compatible with a wide range of Dolphin robotic pool cleaners
Cons:- Requires regular rinsing every 4-6 weeks for consistent performance
- May need replacement if damaged or heavily clogged
Best for: Dolphin owners seeking a durable, broad-compatibility debris basket that reduces clogging during regular use
Not ideal for: Pool owners looking for ultra-fine particle filtration or a filter specifically for small debris, as this basket primarily targets larger debris
- Compatibility:Dolphin S50, S100, Active 15, Echo, T15, Proteus DX3, E20, Cayman, Escape, Nautilus CC, Encore, E10, Solo, Advantage
- Material:ABS plastic
- Dimensions:Same as original model number 9991460-R1
- Durability:Supports filter layer, prevents breakage
- Maintenance:Rinse every 4-6 weeks
Our verdict“This pick is ideal for Dolphin owners who prioritize durability and broad compatibility for debris collection with moderate maintenance.”
Ultra Fine Filters Compatible with Dolphin Nautilus CC Plus, Nautilus CC Supreme, M200/M400/M500 – 4 Pack
This 4-pack of pleated ultra-fine filters offers excellent efficiency at removing small particles, making it a strong choice for owners who want to keep their pools exceptionally clear. Unlike the Ultra-Fine Filter Panels for Dolphin Models, which are limited to certain Dolphin models, this set provides a cost-effective bulk solution that can last 2-3 years with regular rinsing. The filters’ heavy-duty ABS plastic construction ensures durability, but they are not compatible with older Nautilus or Triton models, which could be a drawback for those with legacy cleaners. For those who need frequent filtration of fine debris, this pack offers long-term savings and reliable performance.
Pros:- Highly efficient at removing small particles
- Durable construction with heavy-duty ABS plastic
- Cost-effective 4-pack for long-term use
Cons:- Not compatible with Nautilus (old), Triton, or Triton PS models
- Requires rinsing every 4-6 weeks for optimal performance
Best for: Owners of Dolphin Nautilus CC Plus, Nautilus CC Supreme, or M200/M400/M500 cleaners seeking economical, high-capacity replacements
Not ideal for: Owners of older Nautilus or Triton models, as these filters are incompatible with those units
- Size:10-1/2″(L) x 6-3/8″ (W)
- Pack Quantity:4
Our verdict“This set is best suited for Dolphin owners wanting a bulk, budget-friendly solution for fine particle filtration in compatible models.”
Dolphin Filters 9991432-R4 Replacement Pool Filter (4 Pack) for M400/M500, Nautilus CC Plus
This 4-pack leverages a 3-layer diamond grid design with enhanced PET fiber material to boost filtration and impact resistance, outperforming basic filters like the Ultra-Fine Filter Panels for Dolphin Models in durability and filtration depth. While it covers multiple Dolphin models, it’s not compatible with Nautilus CC or Nautilus CC Pro, which limits its versatility for some owners. The specialized 3-layer construction helps capture finer debris, but the 4-pack may be more than necessary for small pools, leading to unused filters over time. Still, for larger pools or frequent cleaning needs, this set provides a reliable, durable upgrade.
Pros:- Enhanced PET fiber material for durability
- 3-layer diamond grid improves filtration performance
- Compatible with multiple Dolphin models
Cons:- Not compatible with Nautilus CC or Nautilus CC Pro
- Only available in 4-pack, which may be more than needed for small pools
Best for: Dolphin owners with M400, M500, or Nautilus CC Plus cleaners who want enhanced filtration and long-lasting filters
Not ideal for: Owners of Nautilus CC or Nautilus CC Pro, due to incompatibility, or small pools with infrequent cleaning needs
- Product Dimensions:6 x 3 x 2 inches
- Item Weight:15.2 ounces
- Part Number:9991432-R4
Our verdict“This filter set suits Dolphin owners needing durable, high-filtration upgrades for larger or heavily used pools.”
Ultra-Fine Filter Panels for Dolphin Robotic Pool Cleaner (Part# 9991467-R4)
Designed for a wide range of Dolphin models, these ultra-fine filter panels provide high-efficiency filtration to capture fine dirt and debris, making them ideal for pools with lots of small particles. Compared to the basket-style filters, these panels offer easier cleaning and reusability, especially for owners of models like the Active 20 or Explorer E30. However, their compatibility is limited to specific Dolphin models, which could be a constraint for owners with different cleaners. The requirement for manual cleaning means regular maintenance, but for those who prioritize fine debris removal, these panels deliver reliable performance.
Pros:- Provides high-efficiency filtration for cleaner pools
- Easy to install, remove, and clean
- Reusable with simple hose cleaning
Cons:- Compatibility limited to specific Dolphin models
- Requires manual cleaning for consistent performance
Best for: Owners of Dolphin models like Active 20, 30, or Mercury who need high-efficiency, easy-to-clean filtration panels
Not ideal for: Owners of models outside the listed compatible units or those seeking disposable filters for occasional use
- Part Number:9991467-R4
- Compatibility:Active 20, 30, 30i, 40, 60; Advantage Ultra; Discovery; Explorer E30, E50; M600; Mercury; Premium; Proteus DX4, DX5i; Prowler 920, 930, 930W; Quantum; S200, S300, S300i, S400; T35, T45, T55i; Triton PS, PS Plus; Warrior SE, SI
Our verdict“This filter panel set is best for Dolphin owners wanting high-quality, reusable filters for fine debris in compatible models.”
Ulticor Ultra Fine Filter Basket Compatible with Dolphin Robotic Pool Cleaners S50, S100, Active 10, Active 15, Echo, T15, T25, Proteus DX3, Saturn, Cayman, Escape, Prowler 910, Prowler 917, Warrior SL, Encore, E10, Explorer E20, Solo, Advantage, Nautilus CC
This aftermarket ultra-fine filter basket from Ulticor emphasizes microfiltration to keep pool water clear, compatible with many Dolphin models. Compared with the Ultra Fine Filters for Dolphin Nautilus CC Plus, it covers more models, making it a versatile choice for owners with multiple cleaners. Regular rinsing every 4-6 weeks is recommended to maintain performance, but some older Active 10 or S50 models might require modifications for optimal fit. Its high-quality construction ensures durability, though it demands periodic maintenance to prevent clogging.
Pros:- Effective microfiltration for cleaner pools
- Compatible with many Dolphin models
- High-quality, durable construction
Cons:- Not compatible with Nautilus CC Pro or Nautilus CC Supreme
- Requires regular rinsing every 4-6 weeks
- Potential modification needed for some older models
Best for: Dolphin owners with multiple models wanting a comprehensive, microfiltration solution that emphasizes durability
Not ideal for: Owners with Nautilus CC Pro or Nautilus CC Supreme, or those seeking filters requiring minimal maintenance
- Compatibility:Various Dolphin models (see list for specific models)
- Material:Microfiltration technology
- Maintenance:Rinse and clean every 4-6 weeks
Our verdict“This filter basket suits Dolphin owners seeking versatile, durable microfiltration across multiple models with regular maintenance.”
PUREBURG Ultra-Fine Filter Panels Compatible with Dolphin M200 M400 M500 and Nautilus CC Plus Robotic Pool Cleaner, Pack of 8
This set of 8 ultra-fine filter panels offers an excellent solution for maintaining a spotless pool, especially when compared to standard filters that often miss tiny particles. Made with sturdy pleated fabric and a durable plastic frame, these filters excel at capturing sand, sediment, and leaves, making them ideal for pools with frequent fine debris. They are specifically compatible with Dolphin M200, M400, M500, and Nautilus CC Plus models, which means you get a tailored fit but not universal compatibility—something to keep in mind. While rinsing every 4-6 weeks is necessary to maintain peak performance, the high-efficiency filtration makes this a worthwhile tradeoff for pool owners focused on clarity. Compared with other ultra-fine options like the Hayward cartridges, these panels are more about debris capture than longevity, requiring more frequent rinsing. Overall, this pack is perfect for those who prioritize fine debris removal and are comfortable with periodic maintenance, but less so for users seeking universal compatibility or longer-lasting filters.
Pros:- High-efficiency ultra-fine filtration captures small debris effectively
- Sturdy pleated fabric ensures durability during cleaning
- Easy to rinse and maintain for optimal performance
- Includes 8 panels for extended use and replacement
Cons:- Requires rinsing every 4-6 weeks, which can be frequent
- Limited compatibility—only fits selected Dolphin and Nautilus models
Best for: Pool owners with frequent fine debris like sediment or algae spores, seeking high-efficiency filtration for Dolphin or Nautilus models
Not ideal for: Owners looking for universal filters or those with minimal fine debris who prefer low-maintenance options
- Quantity:8-pack
- Product Dimension:10 1/2″ x 6 3/8″
- Compatible Models:Dolphin M200, M400, M500, Nautilus CC Plus
- Filtration Type:Ultra-fine pleated fabric
- Material:Plastic frame with fabric
- Maintenance:Rinse every 4-6 weeks
Our verdict“Best suited for owners who need reliable, high-efficiency debris removal for specific Dolphin and Nautilus models and don’t mind regular rinsing.”
Replacement Robotic Pool Cleaner Filter Cartridges, Ultra Fine, for Hayward Robotic AquaVac, TigerShark, and SharkVac Pool Cleaners (4 Pack)
This 4-pack of ultra-fine filter cartridges is designed for Hayward robotic cleaners like TigerShark, SharkVac, and AquaVac, offering a durable and long-lasting solution. Made with impact-resistant ABS frames and PET fiber filters, these cartridges are built to withstand rough use and last 2-3 years—far longer than the typical filters like the PUREBURG panels, which require more frequent rinsing. They are highly effective at filtering dirt and debris, ensuring your pool stays clean with regular cleaning every 4-6 weeks. Compared to other ultra-fine filters that may need frequent replacement, these cartridges are a practical investment for owners who want durability and less maintenance. However, their compatibility is limited to specific Hayward models, and if your pool has heavy debris loads, you might find yourself replacing them sooner. These cartridges are ideal for those prioritizing longevity and durability over universal fit or extremely fine debris capture.
Pros:- Highly effective at filtering dirt and debris with ultra-fine grid
- Impact-resistant ABS frame ensures durability
- Long-lasting filter life of 2-3 years reduces replacement frequency
- Easy to clean and replace, simplifying maintenance
Cons:- Requires cleaning every 4-6 weeks, similar to other filters
- Limited compatibility—only fits specific Hayward models
- May need earlier replacement if used in heavily debris-laden pools
Best for: Hayward owners seeking durable filters that last multiple seasons and require minimal replacement
Not ideal for: Pool owners with non-Hayward cleaners or those needing ultra-fine debris capture in highly sediment-heavy environments
- Part Number:RCX70101

Factors to Consider When Choosing Replacement Filters For Automatic Pool Cleaners
Selecting the right replacement filter involves more than just matching it to your cleaner. Consider compatibility, filtration quality, and durability, but also be mindful of your pool size and typical debris load. A filter that performs well with heavy debris might be overkill for a lightly used pool, while a budget option may struggle with fine particles or frequent use. Understanding these factors can help you avoid common mistakes like buying incompatible filters or choosing ones that wear out quickly. Here are some key considerations to keep in mind:Compatibility and Fit
Ensuring your replacement filter fits your specific pool cleaner model is essential. Many filters are designed for particular brands like Dolphin or Hayward, and even within those brands, models may have different sizes or connection types. Buying an incompatible filter can lead to poor performance or even damage your cleaner. Always double-check the model number and compatibility notes before purchasing, and consider universal or multi-brand filters if you own multiple cleaners.
Filtration Efficiency
The primary purpose of a replacement filter is to trap dirt, debris, and microscopic particles. Ultra-fine mesh filters excel at capturing smaller contaminants, resulting in cleaner water and less maintenance. However, these filters can clog faster, requiring more frequent cleaning or replacement. Conversely, coarser filters last longer but may let smaller debris slip through. Decide whether your priority is maximum cleanliness or ease of maintenance, and choose accordingly.
Durability and Maintenance
Durability is a key factor in total cost of ownership. A high-quality filter may cost more upfront but can last significantly longer, especially with proper cleaning and storage. Some filters are easier to clean than others—look for models that can be rinsed quickly without deteriorating. Keep in mind that filters exposed to heavy debris or high usage may need more frequent replacement, so balancing cost and longevity is vital for ongoing performance.
Value and Pack Size
Buying in bulk often reduces the per-unit cost, making large packs appealing for frequent users or multiple cleaners. However, not all bulk options are equally durable or compatible with your equipment. Consider how often you need to replace filters and whether the lower-cost, multi-pack filters meet your performance standards. Sometimes, investing in fewer, higher-quality filters can save money in the long run by reducing replacements and maintaining better cleaning efficiency.
Price and Overall Investment
While budget filters might seem attractive, they can compromise durability or filtration quality, leading to more frequent replacements. Premium filters typically offer enhanced durability and finer filtration but come at a higher initial cost. Think about your long-term cleaning needs: if you have a large or heavily used pool, spending more on a durable, high-performance filter can be worthwhile. For smaller or less-frequent pools, budget options may suffice, provided they meet your cleaning standards.
Frequently Asked Questions
How often should I replace my pool cleaner filters?
The replacement frequency depends on your pool’s debris load and filter quality. Typically, ultra-fine filters need cleaning every 1-2 weeks and replacement every few months if used regularly. Coarser filters may last longer but could require more frequent cleaning to maintain optimal flow. Always inspect your filters regularly and replace when they show signs of deterioration or clogging that cleaning cannot resolve effectively.
Can I use filters from different brands interchangeably?
Interchanging filters from different brands is only advisable if they are explicitly designed to be compatible or are universal models. Incompatible filters may not fit properly, leading to reduced suction or leaks, and could damage your cleaner. Always verify compatibility details before trying to substitute filters from different brands, and when in doubt, stick with recommended or universal options tested for your specific model.
Are ultra-fine filters worth the extra cost?
Ultra-fine filters are particularly beneficial if you prioritize water clarity and minimal debris in your pool. They capture smaller particles that coarser filters might miss, reducing the need for frequent skimming or chemical adjustments. However, they can clog faster and often require more maintenance, which might be inconvenient for some users. For those who want the cleanest water and are willing to maintain their filters regularly, ultra-fine options are a solid investment.
What is the best way to clean and maintain replacement filters?
Most filters can be rinsed with a garden hose to remove accumulated debris. Avoid using harsh chemicals or brushes that could damage the mesh. Regular cleaning after each use prolongs the filter’s lifespan and maintains proper water flow. For filters that are heavily soiled or clogged, some may be gently washed with a mild soap solution, but always check manufacturer instructions. Proper storage when not in use also helps prevent deterioration and mold growth.
Should I buy filters in bulk or as singles?
Bulk packs often provide better value if you have a high-use pool or multiple cleaners, but not all bulk options deliver the same quality or compatibility. If you only need occasional replacements, singles or smaller packs might be more cost-effective and less wasteful. Evaluate your cleaning frequency, budget, and the durability of the filters to decide whether investing in bulk packs makes sense for your situation.
Conclusion
For most users, the Ultra Fine Filters Compatible with Dolphin Nautilus CC Plus stand out as the best overall choice due to their superior filtration and compatibility. Budget-conscious buyers will appreciate the value offered by the PUREBURG Ultra-Fine Filter Panels Pack of 8, while owners seeking durability might prefer the Advanced Ultra Fine Filter Basket for Dolphin Cleaners. Beginners or those with infrequent use should opt for simpler, more affordable options, whereas serious pool enthusiasts may find the higher-end filters justified by their longevity and performance. Matching your pool’s size, debris load, and cleaning schedule to the right filter ensures optimal results and a cleaner pool season after season.
