More Details on Our Top Picks
Replacement Robotic Pool Cleaner Filter Cartridges, Ultra Fine Cartridge Filter Panels, for Hayward Robotic AquaVac, TigerShark, and SharkVac Pool Cleaners (2 Pack)
This ultra-fine filter cartridge set stands out for its broad compatibility with multiple Hayward robotic cleaners, including TigerShark, SharkVac, and AquaVac models. Compared to the RCX70101PAK2 filters, these cartridges are more impact resistant and easier to disassemble for cleaning, making routine maintenance simpler. While they require regular rinsing every 4-6 weeks, their durable construction means they can last 2-3 years with proper care, providing excellent value. However, their specificity means they won’t fit non-Hayward models, and they need periodic cleaning to prevent clogging. This pick is ideal for owners of Hayward robots seeking a long-lasting, high-performance filter set.
Pros:- Highly effective at filtering dirt and debris
- Impact resistant and durable materials
- Reusable and easy to clean
Cons:- Requires regular cleaning every 4-6 weeks

- Lasts:2-3 years
Our verdict“This filter set offers long-lasting, effective filtration for dedicated Hayward robot users willing to maintain it regularly.”
Replacement Part RCX97417SPAK2 Door Filter Element (4 Pack)
This 4-pack of door filter elements is a practical choice for maintaining consistent water clarity in pools using suction cleaners. Compared with the more specialized robotic filters like the Ultra Fine Filters for Dolphin, these are designed to fit standard suction systems, making them versatile for different setups. While they are effective at removing impurities, the lack of detailed material info means you may need to monitor their condition more closely. They are an economical option for those who prefer bulk replacements but are less suited for owners of robotic cleaners or systems requiring ultra-fine filtration. If your focus is on simple, ongoing filtration, these offer a reliable solution.
Pros:- Effective at filtering impurities
- Includes four filter elements for extended use
- Cost-efficient for ongoing maintenance
Cons:- Designed specifically for compatible systems, not universal
- Limited material detail, potential durability concerns
Best for: Pool owners with suction-based cleaning systems needing affordable, bulk replacement filters
Not ideal for: Owners of robotic cleaners like Dolphin or Hayward robots who need specialized or ultra-fine filters
- Part Number:RCX97417SPAK2
- Quantity:4-pack
Our verdict“A solid, budget-friendly option for maintaining water quality in suction-based pool cleaners.”
Ultra Fine Filters Compatible with Dolphin Nautilus CC Plus, M200/M400/M500, 4 Pack
This set of pleated ultra-fine filters excels at trapping small particles in Dolphin Nautilus series cleaners, making water visibly clearer. Compared to the Ulticor Ultra Fine Filter Basket, these filters are designed specifically for Nautilus and M series models, offering a precise fit and effective filtration. Their 2-3 year lifespan with regular rinsing makes them a cost-effective choice for owners prioritizing clean water. However, they are incompatible with older Nautilus, Triton, or Triton PS models, which may require different filters. For Dolphin owners focusing on fine particle removal, these filters deliver noticeable results but require routine maintenance.
Pros:- Excellent at removing small particles
- Durable construction with 2-3 year lifespan
- Cost-effective pack of four
Cons:- Not compatible with older Nautilus or Triton models
- Requires rinsing every 4-6 weeks
Best for: Dolphin Nautilus and M series users seeking effective small-particle filtration
Not ideal for: Owners of older Dolphin models or Triton series who need different filter sizes
- Compatibility:Dolphin Nautilus CC Plus, M200, M400, M500
- Part Number:9991432-R4
- Size:10-1/2”(L) x 6-3/8” (W)
- Material:Heavy-duty ABS plastic
- Pack Quantity:4
Our verdict“Ideal for Dolphin Nautilus owners who want to improve water clarity with reliable, fine filtration.”
RCX70101PAK2 Robotic Pool Filter Compatible with Hayward TigerShark and SharkVac (2 Pack)
This 2-pack of filters offers a reliable solution for Hayward TigerShark and SharkVac owners who want a consistent cleaning experience. Compared to the Replacement Robotic Pool Cleaner Filter Cartridges, these filters include a fixed PET polyester layer that prevents detachment, ensuring long-term durability. The 74-micron filtration accuracy strikes a good balance between debris removal and water flow, making them suitable for regular use. Regular rinsing is still necessary, but their compatibility with multiple models and sturdy design make them a practical choice for routine maintenance. They do not, however, match the ultra-fine filtering of some Dolphin models, which may matter for those seeking the clearest water possible.
Pros:- Compatible with multiple Hayward models
- Durable, fixed filter layer prevents detachment
- Efficient 74-micron filtration
Cons:- Requires regular rinsing
- May need replacement if heavily clogged
Best for: Hayward robotic cleaner owners who want broad compatibility and durable filters
Not ideal for: Owners of Dolphin models or those requiring ultra-fine filtration for very small particles
- Compatibility:Hayward TigerShark, SharkVac, Aqua Vac
- Material:ABS plastic frame, PET polyester filter
- Filtration accuracy:74 microns
- Package:2 Pack
- Warranty:1 year
Our verdict“This filter set is well-suited for Hayward users seeking dependable, long-lasting filtration without ultra-fine particle removal.”
Ulticor Ultra Fine Filter Basket Compatible with Dolphin Robotic Pool Cleaners
This high-grade microfiltration basket excels at trapping tiny debris, making it ideal for Dolphin models like the S50, S100, and Prowler series. Compared to the Ultra Fine Filters for Dolphin, this basket emphasizes high-quality microfiltration technology, which results in cleaner water and fewer particles passing through. It’s easy to rinse and maintain every 4-6 weeks, and its compatibility with a broad range of Dolphin cleaners makes it a versatile choice. However, it does not fit older or specialized Dolphin models like the Nautilus CC Pro, and some users may need to remove a plastic piece for fit on certain models. For those prioritizing microfiltration, this basket offers a significant upgrade.
Pros:- High-quality microfiltration technology
- Compatible with many Dolphin models
- Easy to rinse and maintain
Cons:- Not compatible with Nautilus CC Pro or Nautilus CC Supreme
- May require removal of plastic parts for older models
Best for: Dolphin owners seeking superior microfiltration for cleaner water and minimal maintenance
Not ideal for: Owners of Nautilus CC Pro or models requiring larger capacity baskets
- Compatibility:Dolphin S50, S100, Active 10, Active 15, Echo, T15, T25, Prowler series, and more
- Material:Microfiltration technology
- Note:Not compatible with Nautilus CC Pro, Nautilus CC Supreme
Our verdict“A prime choice for Dolphin users who want to maximize particle removal and enjoy easy upkeep.”
Replace Part#9991467-R4 Ultra-Fine Filter Panels Compatible with Dolphin Robotic Pool Cleaners
This set of ultra-fine filter panels excels at capturing fine dirt and debris across a broad range of Dolphin models, including the S200 and M600, making it a versatile choice for pool owners seeking high filtration efficiency. Unlike the single-model-specific filters, these panels are washable and reusable, which can save money over time despite the slightly more involved cleaning process. Compared to the Ultra-Fine Filter Panels for Dolphin (Product 9), these offer broader compatibility and durability, but their installation requires careful matching to model to avoid fit issues. The high-quality, washable plastic ensures longevity and effective debris trapping, which is ideal for maintaining a pristine pool. However, the installation process may be tedious for some users, and the price is not specified, which could impact value perception for budget-conscious buyers.
Pros:- Compatible with numerous Dolphin robotic pool cleaner models
- Reusability reduces ongoing costs and environmental impact
- Made from durable, high-quality washable plastic
- Effective at capturing fine dirt and debris
Cons:- Installation may require careful model matching, which could be tricky
- Cleaning process is slightly tedious for some users
- Price information is not provided, making cost evaluation difficult
Best for: Pool owners with multiple Dolphin models who want a durable, reusable filter solution that covers a wide range of cleaners.
Not ideal for: Casual users or those with only a single Dolphin model, as the time and effort to install and clean may outweigh benefits.
- Part Number:9991467-R4
- Compatible Models:Active 20, Active 30, Active 30i, Active 40, Active 60, Advantage Ultra, Discovery (New), Explorer E30, E50, E70, M600, Mercury, Premium, Proteus Dx4, Dx5i, Prowler 920/930/930w, Quantum, S200, S300, S300i, S400, T35, T45, T55i, Triton Ps, Triton Ps Plus, Warrior Se, Warrior Si
- Material:High-quality washable plastic
- Type:Ultra-fine pleated filter panels
Our verdict“This pick is ideal for pool owners seeking versatile, long-lasting filters for multiple Dolphin models who don’t mind a bit of maintenance.”
Pool Replacement Filter Compatible with Hayward RCX70101PAK2
This replacement filter offers reliable dirt and debris filtration for Hayward Tiger Shark models, such as RC9990GR and RC4702, providing a solid option for seasonal or annual replacements. Compared to the 4-pack of Hayward Sharkvac filters (Product 8), this single filter is more suited for ongoing, regular replacements rather than extended use, but it simplifies compatibility and replacement. Its durable plastic frame and high-quality filter material ensure consistent performance, and its straightforward replacement process makes it accessible for most pool owners. However, the need for periodic replacement depending on debris levels could add ongoing costs, and thorough cleaning is recommended to maintain optimal flow and filtration.
Pros:- Effective at filtering dirt and debris
- Durable plastic frame ensures longevity
- Compatible with multiple Hayward Tiger Shark models
- Easy to replace and clean
Cons:- Requires regular replacement based on debris load

- Filter Material:High-quality filter material
- Frame:Plastic
- Replacement Frequency:Seasonal or annual
Our verdict“This filter is a practical choice for Hayward Tiger Shark owners who need reliable, easy-to-maintain replacements at an affordable price.”
4 Pack Replacement Pool Filter Cartridges for Hayward Sharkvac Robotic Pool Cleaners
This 4-pack of replacement cartridges is designed for Hayward SharkVac and similar models, featuring a 3-layer design with PET fiber material that enhances filtration and impact resistance. Compared to individual filters, this set offers better value and convenience for regular replacements, especially for owners with larger or in-ground pools. The cartridges are compatible with multiple Hayward robotic cleaners, making them versatile. While their impact-resistant PET fiber ensures durability, the filters require routine maintenance and rinsing to maintain optimal performance. The absence of specific pricing or user ratings means buyers should weigh the cost-effectiveness based on their usage patterns.
Pros:- Compatible with a wide range of Hayward robotic cleaners
- Includes four filters for ongoing use
- Enhanced PET fiber material improves filtration and impact resistance
- Cost-effective for frequent replacements
Cons:- No specific price data available for comparison

Our verdict“This set offers good value and durability for owners who need frequent filter replacements for heavy debris loads.”
Ultra-Fine Filter Panels for Dolphin Robotic Pool Cleaner (4 Pack)
This 4-pack of ultra-fine filter panels is compatible with a wide array of Dolphin models, such as the Active 20 and M600, and offers high-efficiency filtration via pleated plastic panels. Compared with the 4-pack of generic Dolphin filters (Product 10), these panels provide a straightforward, easy-to-clean design, but their effectiveness depends on regular maintenance. Their compatibility with many Dolphin models makes them versatile, though they require careful installation and regular rinsing to sustain performance. The numbered panels facilitate correct placement, reducing user error. However, some users might find the need for frequent cleaning a minor inconvenience, especially if they have multiple cleaners or a heavily debris-laden pool.
Pros:- Compatible with numerous Dolphin models
- High-efficiency filtration captures fine dirt
- Reusable and easy to clean
- Panels are numbered for correct placement
Cons:- Requires regular cleaning to maintain effectiveness
- Compatibility limited to specified Dolphin models
- Potentially tedious if multiple panels are used frequently
Best for: Dolphin owners who want a reliable, high-efficiency filtration solution that is easy to maintain and compatible with multiple models.
Not ideal for: Casual users or those with non-Dolphin cleaners, as compatibility is limited beyond Dolphin models.

9991468-R4 Ultra-Fine Filter Compatible with Dolphin Robotic Pool Cleaners
This set of four ultra-fine pleated filter panels is designed for durability, with heavy-duty ABS plastic construction that withstands regular use and lasts 2-3 years. Compared to the other Dolphin-compatible filters, such as Product 9, this option emphasizes longevity and broad compatibility with models like the Nautilus CC and Explorer E20. The filters trap small particles efficiently, helping maintain a clearer pool, and their durable build resists ripping and damage over time. However, they require rinsing every 4-6 weeks, which may be a slight inconvenience for busy pool owners. The inclusion of a one-year warranty adds peace of mind, but the lack of specific pricing info could be a consideration for budget-conscious buyers.
Pros:- Durable ABS plastic construction resists ripping and lasts 2-3 years
- Compatible with a wide range of Dolphin models
- Includes four filters for extended use
- Effective at trapping small particles
Cons:- Requires rinsing every 4-6 weeks for optimal performance
- No specific price info available

Replacement Pool Filter Cartridge for Dolphin M400/M500, Nautilus CC Plus (4 Pack)
This set of four replacement cartridges stands out for its advanced PET fiber material and three-layer design, which together boost filtration performance and impact resistance. Compared with ultra-fine filters like the one for Dolphin Nautilus CC Plus, these cartridges prioritize durability and effective debris trapping for common pool dirt and larger particles. However, they are not compatible with Nautilus CC Pro or earlier models, which could be limiting for owners with different Dolphin units. The easy replacement process makes these a convenient choice for routine maintenance, though the need for regular replacement when filtration declines means ongoing costs. The durable three-layer design helps prevent damage during handling, making them more reliable over time.
Pros:- Effective debris filtration thanks to enhanced PET fiber material
- Durable 3-layer design increases impact resistance
- Simple to replace, minimizing downtime
Cons:- Not compatible with Nautilus CC or Nautilus CC Pro models
- Requires regular replacement as filtration performance declines

How We Picked
These products were evaluated based on a combination of filtration efficiency, compatibility with popular robotic pool cleaners, build quality, ease of installation, and value for money. We prioritized filters that deliver consistent performance and are easy to replace, ensuring they meet the needs of both casual pool owners and more frequent users. The ranking reflects a balance between cost and performance, with top picks offering the best combination of durability and cleaning power. Filters that stand out in these categories were positioned higher, while those with notable tradeoffs or limited compatibility ranked lower.Factors to Consider When Choosing Replacement Filters For Automatic Pool Cleaners
Choosing the right replacement filter involves more than just matching model numbers. Consider how often you clean your pool, the types of debris you encounter, and your budget. A filter that captures fine debris is ideal for crystal-clear water but may need more frequent cleaning. Compatibility is key—ensuring the filter fits your specific cleaner prevents unnecessary returns and exchanges. Durability matters, especially if your pool is in frequent use, as longer-lasting filters can save money over time. Additionally, ease of maintenance can influence your overall satisfaction, so look for filters that are simple to install and clean.Filtration Efficiency and Debris Size
Filters with ultra-fine meshes are better suited for pools with lots of fine dirt, algae, or debris that cloud the water. While they do a superior job capturing tiny particles, these filters might clog faster, requiring more frequent cleaning. Conversely, coarser filters are easier to maintain but may miss finer particles, leading to less clear water. Think about your typical pool conditions and choose a filter that strikes the right balance between filtration performance and ease of maintenance.
Compatibility and Fit
Matching the filter to your specific pool cleaner model is critical. Some filters are designed for a broad range of models, offering versatility, while others are highly specific. Incorrect fit can lead to poor sealing, reduced cleaning efficiency, or damage to your cleaner. Always verify the model number compatibility before purchasing and consider whether you might upgrade your pool cleaner in the future, which could influence your choice of a more universal filter.
Durability and Longevity
Higher-quality filters often boast more durable materials, enabling them to withstand frequent use and harsh pool chemicals better. While these may come at a higher upfront cost, they can reduce the frequency of replacements, saving money in the long run. Cheaper filters might seem appealing initially but could degrade faster or require more frequent replacement, ultimately costing more over time.
Ease of Installation and Cleaning
Some filters are designed for quick and tool-free installation, which can be a real time-saver. Consider how easy it is to remove, clean, and reinstall the filter—especially if you plan to do it regularly. Filters with accessible design features or washable components tend to make maintenance less of a chore, encouraging more consistent upkeep and better overall performance.
Cost-Effectiveness and Value
While premium filters typically cost more upfront, they often last longer and perform better, offering better value over their lifespan. Cheaper options might fit tight budgets but could lead to more frequent replacements and reduced cleaning efficiency. Balancing initial cost with expected longevity and performance is key to making a satisfying purchase.
Frequently Asked Questions
How often should I replace my pool cleaner’s filter?
The frequency of replacement depends on your pool’s usage and debris levels. Generally, filters should be checked weekly and replaced or cleaned every 4-6 weeks during regular use. If your pool accumulates a lot of debris or you notice reduced cleaning performance, more frequent replacements may be necessary. Proper maintenance extends the life of your filters and helps maintain optimal cleaning efficiency.
Can I use a generic or universal filter with my pool cleaner?
While some universal filters are compatible with multiple models, compatibility is not always guaranteed. Using the wrong size or type can lead to leaks or poor filtration. It’s best to verify the specific model number and compatibility details before choosing a generic option. When in doubt, sticking with manufacturer-recommended filters ensures a proper fit and reliable performance.
Are ultra-fine filters worth the extra cost?
Ultra-fine filters are a good investment if you want crystal-clear water and have fine debris like pollen, algae, or small dirt particles. They do tend to clog faster and may require more frequent cleaning, but the improved water quality often justifies the expense. For pools with high debris loads or for owners who prioritize water clarity, these filters deliver noticeable benefits.
What is the best way to clean and maintain replacement filters?
Most filters should be rinsed thoroughly with a hose to remove debris after each use, especially if they are washable. Avoid using harsh chemicals that could degrade the filter material. Regular inspection for tears or damage is important, and replace filters that show signs of deterioration. Proper cleaning and handling extend the lifespan of your filters and keep your pool cleaner.
Should I buy more than one filter at a time?
Purchasing multiple filters can be a smart move if your pool gets heavy use or if you want to minimize downtime. Having replacements ready allows for quick swaps during routine maintenance, ensuring your cleaner operates without interruption. Consider your frequency of use and storage space—buying in bulk often reduces the overall cost per filter and simplifies maintenance scheduling.
Conclusion
For casual pool owners seeking reliable performance without breaking the bank, the Replacement Part RCX97417SPAK2 Door Filter Element offers affordability and decent filtration. Those who prioritize the clearest water should consider high-quality, ultra-fine options like the Replacement Robotic Pool Cleaner Filter Cartridges for their superior debris capture. If durability and long-term value matter most, investing in premium filters that last longer can be worthwhile. Beginners will benefit from filters that are easy to install and maintain, while experienced users with heavy debris loads should opt for filters with fine mesh and high durability. Overall, matching the filter to your specific pool conditions and budget will lead to the best results.Fall Picks
