More Details on Our Top Picks
Ultra-Fine Filter Panels for Dolphin Robotic Pool Cleaner (4 Pack)
This set of four ultra-fine filter panels stands out for its broad compatibility across many Dolphin models, including S200, Proteus DX4, and Triton PS. The filters are designed for high-efficiency filtration, capturing very fine dirt and debris that can slip through standard filters, making pool water visibly cleaner. Compared with the Replace Part#9991467-R4 panels, these offer similar filtration performance but come in a larger pack, providing better value and less frequent replacements. Their ease of cleaning—simply rinsing with a garden hose—reduces maintenance time while keeping the filters effective. However, regular cleaning is needed to prevent clogging, and their compatibility is limited to specific Dolphin models, so they won’t fit all robotic cleaners. These filters are ideal for owners who want reliable, ultra-fine filtration without frequent replacements, especially if they own multiple Dolphin units.
Pros:- Broad compatibility with many Dolphin models
- High-efficiency filtration captures fine dirt
- Easy to clean and reinstall with a hose
- Numbered panels for simple installation
Cons:- Requires regular cleaning to prevent clogging
- Compatibility limited to specific Dolphin models
Best for: Dolphin owners seeking versatile, high-efficiency filters that fit a wide range of models and simplify maintenance
Not ideal for: Owners of non-Dolphin robotic cleaners or those seeking the most budget-friendly, basic filters

- Features:High-efficiency filtration, easy cleaning, numbered for installation
Our verdict“This set is perfect for Dolphin owners who want reliable, versatile filters that deliver thorough cleaning with minimal fuss.”
PUREBURG Ultra-Fine Filter Panels Compatible with Dolphin M200 M400 M500 and Nautilus CC Plus Robotic Pool Cleaner, Pack of 8
The PUREBURG 8-pack of ultra-fine filter panels offers excellent value, especially for owners with multiple compatible robotic cleaners like Dolphin M200, M400, M500, and Nautilus CC Plus. These filters feature a sturdy pleated fabric and heavy-duty ABS plastic frame, making them durable enough for regular rinsing and reuse. Compared to the smaller sets, such as the Ultra-Fine Filter Panels for Dolphin, this pack reduces per-unit cost and ensures you always have a spare on hand. They effectively trap fine debris like sand, sediment, and leaves, improving overall water clarity. The main tradeoff is that they require rinsing every 4-6 weeks to maintain their effectiveness, and over extended use, some panels may need replacing. This pick makes the most sense for budget-conscious owners who prefer bulk buying and durable filters for routine cleaning.
Pros:- Bulk pack offers great value

Their diamond-shaped grid filters out dirt, debris, and fine particles, ensuring your pool water stays clear. Compared with Dolphin-specific filters like the Replace Part#9991467-R4, these are more limited in compatibility but excel at filtering smaller debris in Hayward and Maytronics units.

The filters are made from high-quality, washable plastic, allowing repeated use after rinsing, which extends their lifespan compared to disposable options. They excel at capturing dirt, fine debris, and stains, ensuring a visibly cleaner pool. Compared to the Ultra-Fine Filter Panels for Dolphin 4-pack, this set emphasizes durability and compatibility across many models, but installation must match the specific model compatibility. Over time, heavy wear might necessitate replacement. These filters are ideal for owners seeking durable, easy-to-clean options that fit a broad range of Dolphin units.
Pros:- Compatible with extensive Dolphin models
- High-quality, washable material
- Effective at capturing fine dirt and stains

Our verdict“This flexible, washable filter set is great for Dolphin owners who prioritize durability and broad compatibility.”
Dolphin Filters 9991432-R4 Replacement Pool Filter (4 Pack) for M400/M500, Nautilus CC Plus
The 9991432-R4 set provides four high-quality filters designed specifically for Dolphin M400, M500, and Nautilus CC Plus models. The filters feature a three-layer diamond grid made from innovative PET fiber, which enhances filtration and impact resistance, especially useful for homes with heavy debris loads. Compared to older or simpler filters, such as the Ultra-Fine Filter Panels for Dolphin, this set offers improved durability and debris capture, making it ideal for more demanding pool environments. These filters are reusable, and their impact-resistant design helps them last longer, but they are limited to certain Dolphin models, so compatibility must be checked carefully. They suit owners who want long-lasting, high-performance filters for routine use.
Pros:- Enhanced PET fiber for superior filtration
- Impact-resistant three-layer design
- Includes four filters for convenience
- Reusable and easy to rinse
Cons:- Limited to specific Dolphin models
- May need occasional replacement if heavily worn
Best for: Dolphin owners needing durable, high-filtration capacity filters for heavy debris loads
Not ideal for: Owners with non-compatible Dolphin models or those seeking low-cost disposable options
- Product Dimensions:6 x 3 x 2 inches
- Item Weight:15.2 ounces
- Part Number:9991432-R4
- Compatibility:Dolphin M400, M500, Nautilus CC Plus
- Material:PET fiber, diamond grid
Our verdict“This filter set is suitable for Dolphin owners requiring durable, high-performance filters that withstand demanding conditions.”
Robotic Pool Cleaner Spring Filter Cartridges for Dolphin Nautilus CC Plus & More, 4 Pack
This set of spring filter cartridges stands out for their compatibility across multiple Dolphin models like Nautilus CC Plus, M200, M400, and M500, making them a versatile choice for owners with different Dolphin cleaners. Compared to the Funmit Ultra Fine Cartridge Filters, which focus on trapping finer debris, these filters excel at handling larger debris, reducing clogging and maintenance frequency. However, they require rinsing every 4-6 weeks to maintain peak performance, and their compatibility isn’t universal—some newer Dolphin models might not fit. The durable ABS plastic construction ensures a long lifespan of 2-3 years with proper care, but they are less effective at capturing tiny particles than ultra-fine options. This pick makes the most sense for pool owners seeking robust, reusable filters that cover multiple Dolphin models and prioritize larger debris removal.
Pros:- Compatible with multiple Dolphin models, offering great versatility
- Durable ABS plastic construction for long-term use
- Easy to clean and reusable, reducing ongoing costs
Cons:- Not compatible with some newer Dolphin models, limiting flexibility
- Requires regular rinsing every 4-6 weeks for optimal performance
Best for: Pool owners with multiple Dolphin robotic cleaners needing reliable, durable filters for larger debris.
Not ideal for: Owners with newer or less common Dolphin models, or those primarily needing ultra-fine debris filtration, as compatibility may be limited.
- Compatibility:Dolphin robotic pool cleaners (see details for specific models)
- Material:ABS plastic
- Dimensions:10-1/2″ x 6-3/8″
- Pack Size:4 filters
Our verdict“This set is best suited for owners seeking reliable, reusable filters compatible with several Dolphin models that handle larger debris efficiently.”
RCX70101PAK2 4-Pack Robotic Pool Cleaner Filter Cartridges for Hayward Models
This 4-pack of Hayward-compatible filter cartridges is tailored for TigerShark and SharkVac XL series, making it a solid choice for owners of those models. Compared with the Funmit Ultra Fine Cartridge Filters, which prioritize fine debris, these filters focus on durability and impact resistance thanks to their PET fiber material. While they fit specific Hayward models well, their limited compatibility means owners with other brands should look elsewhere. Installation involves manual removal and replacement, which can be slightly cumbersome, and no clear lifespan data is provided—implying replacement frequency may vary. This option makes sense for Hayward users seeking a durable, impact-resistant filter that can withstand tougher debris without frequent replacement.
Pros:- Compatible with multiple Hayward models like TigerShark and SharkVac XL
- Enhanced PET fiber provides better impact resistance
- Includes four filters for regular replacement
Cons:- Limited compatibility outside specific Hayward models
- Installation is manual and may be a bit cumbersome
Best for: Hayward robotic pool cleaner owners looking for impact-resistant, durable replacement filters.
Not ideal for: Pool owners with non-Hayward models or those seeking ultra-fine debris trapping, as these filters are more impact-resistant than fine filtration.
- Model Number:RCX70101, RCX70101PAK2
- Included:4 filter cartridges
- Dimensions:11-1/2″ x 6-5/8″ x 5/8″
- Top Length:11-7/8″
Our verdict“This pick is ideal for Hayward users needing impact-resistant filters that last through tougher debris loads.”
Funmit Ultra Fine Cartridge Filter Replacement for Dolphin Nautilus CC Plus, M200 / M400 / M500 Robotic Pool Cleaner Parts, Replaces Part # 9991432-R4, 4 Pack
This set of ultra-fine filters excels at trapping small debris like sand, hair, and leaves, making it ideal for pool owners who want a crystal-clear finish. Compared with the Robotic Pool Cleaner Spring Filter Cartridges, which are better at handling larger debris, the Funmit filters focus on finer particles, though they may clog faster if larger debris is present. Made from heavy-duty ABS plastic with pleated filter paper, these filters are durable but require regular rinsing every 4-6 weeks to prevent performance decline. They are not compatible with some Dolphin models, such as Nautilus CC and M600, which limits their universal appeal. With proper maintenance, they can last 2-3 years, but replacement may be necessary sooner if debris loads are high.
Pros:- Excellent at trapping sand, hair, and leaves for a clean pool
- Heavy-duty ABS plastic ensures durability
- Includes four filters for extended use
Cons:- Not compatible with some models like Nautilus CC and M600
- Requires frequent rinsing to prevent clogging and maintain performance
Best for: Pool owners prioritizing ultra-fine debris filtration to keep the water spotless and clear.
Not ideal for: Owners with models outside the specified Dolphin range or those who need to handle larger debris regularly, as these filters are optimized for small particles.
Our verdict“This set is best suited for pool owners who want ultra-fine debris capture and are willing to perform regular rinsing for optimal results.”

Factors to Consider When Choosing Replacement Filters For Automatic Pool Cleaners
Choosing the right replacement filter depends on several factors beyond just compatibility. Understanding these can help you avoid common pitfalls and maximize your investment in pool maintenance.Compatibility with Your Pool Cleaner
Always verify that the filter matches your specific model. Using incompatible filters can reduce filtration efficiency or cause damage. Check the model number and manufacturer recommendations carefully before purchasing. Some filters are designed for a broad range of models, which can be a cost-effective choice, but always double-check fit and size. Mismatched filters may also lead to poor debris capture or faster wear.
Filtration Efficiency and Particle Size
Ultra-fine filters trap smaller debris, improving water clarity but often come with tradeoffs such as higher cost or shorter lifespan. Consider your typical debris load—if your pool frequently collects fine dirt or algae, investing in high-efficiency filters makes sense. Conversely, if your pool mainly deals with larger leaves, standard filters might suffice. Balance the need for clarity against your budget and maintenance willingness.
Durability and Material Quality
High-quality materials extend the lifespan of filters, reducing the frequency of replacements. Look for filters made from durable plastics and tightly woven mesh or foam. Cheaper options might save money upfront but could degrade quickly, leading to higher long-term costs. Consider the environmental conditions of your pool area—harsh sunlight or chemicals can accelerate material wear.
Pack Size and Cost-Effectiveness
Buying in packs often reduces the cost per filter, which is beneficial for frequent replacements or large pools. However, larger packs may lead to unnecessary waste if your pool has a small surface area. Assess your cleaning schedule and pool size to determine the ideal quantity. Remember, cheaper per-unit costs can sometimes mean lower quality, so weigh pack size against filtration performance.
Ease of Installation and Maintenance
Simple, tool-free installation and easy cleaning are significant for hassle-free pool upkeep. Some filters feature snap-in designs that save time, while others require more effort. Look for filters that are straightforward to remove and clean, especially if you plan to replace them frequently. A well-designed filter can reduce the risk of damage during replacement and ensure consistent filtration performance.
Frequently Asked Questions
How often should I replace my pool cleaner’s filters?
The frequency of filter replacement depends on your pool’s debris load and usage. Typically, filters should be checked every few weeks and replaced every 2-4 months for optimal performance. If you notice a significant drop in cleaning efficiency or water flow, it’s time to replace or clean the filter. Regular maintenance extends the life of your cleaner and keeps your pool water clear.
Can I use generic filters for my specific robotic pool cleaner?
While some generic filters are compatible with multiple models, it’s safest to use filters specified by the manufacturer. Generic options may not fit perfectly or provide the same filtration quality, which can reduce your cleaner’s effectiveness. Always verify dimensions and compatibility before purchasing. Investing in proper filters ensures your device operates as intended and lasts longer.
Are ultra-fine filters worth the extra cost?
Ultra-fine filters are beneficial if your pool tends to accumulate fine dirt, algae, or pollen, as they improve water clarity significantly. However, they often cost more and may require more frequent replacements due to clogging. For pools with heavy debris, standard filters might be more practical, but if you prioritize crystal-clear water, ultra-fine options are worth considering.
What is the best way to clean and maintain replacement filters?
Most filters can be rinsed with a garden hose to remove debris, which helps extend their lifespan. Avoid using harsh chemicals or brushes that could damage the filter material. Regular cleaning after each use, especially if you notice reduced suction or cleaning performance, keeps your filters functioning properly. Replacing filters at recommended intervals prevents clogs and ensures consistent filtration.
How do I choose between different pack sizes and brands?
Consider your pool size, frequency of cleaning, and budget. Larger packs often provide better value if you need frequent replacements, but they might be unnecessary for small pools. Brand reputation and compatibility should guide your choice—trusted brands tend to offer better durability and fit. Balancing cost with quality ensures you get effective filtration without overspending.
Conclusion
For most pool owners, the Ultra-Fine Filter Panels for Dolphin Robotic Pool Cleaner provide a reliable, high-performance choice that balances durability and filtration. Budget-conscious buyers should consider the Funmit Ultra Fine Cartridge Filter for effective cleaning at a lower price point. Those with larger pools or demanding debris loads might prefer multi-pack options like the PUREBURG Ultra-Fine Filter Panels or Dolphin Filters 9991432-R4 for extended use. If you prioritize ease of installation and long-term durability, investing in higher-end brands makes the most sense. Ultimately, matching your pool’s specific needs and your maintenance routine will lead to the best filtration results.
