More Details on Our Top Picks
4 Pack Pool Filter Cartridges for Hayward Sharkvac RCX70101PAK2
This set stands out for its broad compatibility with multiple Hayward robotic pool cleaners, including SharkVac and TigerShark models. The use of enhanced PET fiber material boosts filtration efficiency and impact resistance, making it a reliable choice for regular pool maintenance. Compared with the Dolphin filters, this option offers more compatibility across Hayward models, though it lacks specific details on filter lifespan. The inclusion of four cartridges adds convenience, especially for those who prefer to stock up for seasonal replacements. However, buyers should verify their model compatibility before purchasing, as it doesn’t specify exact filter lifespan or cleaning frequency. Choosing these filters makes the most sense for Hayward users seeking a cost-effective, compatible replacement that simplifies maintenance.
Pros:- Compatible with a wide range of Hayward robotic pool cleaners
- Enhanced PET fiber material improves filtration and impact resistance
- Includes four filters for extended use and convenience
Cons:- Compatibility check required to ensure fit with specific models
- No specific information on filter lifespan or cleaning schedule
Best for: Pool owners with multiple Hayward robotic cleaners who want a versatile, all-in-one replacement pack.
Not ideal for: Dolphin users seeking filters optimized specifically for Dolphin models or those needing detailed lifespan info.
- Model Number:RCX70101, RCX70101PAK2
- Compatible With:TigerShark, SharkVac, AquaVac 500 Series
- Number of Filters:4
Our verdict“This pack offers excellent value for Hayward owners needing multiple filters and broad compatibility, though verification is essential.”
Replacement Robotic Pool Cleaner Filter Cartridges, Ultra Fine, for Hayward and Maytronics Pool Cleaners (2 Pack)
This set excels at capturing tiny dirt and debris, thanks to its ultra-fine diamond-shaped grid, making it ideal for those aiming for crystal-clear water. Unlike the Hayward-specific filters, these are compatible with both Hayward and Maytronics models, offering versatility for owners with different brands. The filters are reusable, which can reduce long-term costs, but require regular rinsing every 4-6 weeks to maintain performance. While durability is an advantage, their lifespan is dependent on usage frequency, and they are limited to certain models. This pick makes the most sense for pool owners who prioritize high filtration precision and are comfortable with routine cleaning.
Pros:- Effective ultra-fine dirt and debris filtration
- Reusable design reduces replacement costs
- Durable materials withstand frequent cleaning
Cons:- Requires regular rinsing to sustain performance
- Compatibility limited to specific models
- Filter lifespan varies with usage and cleaning routine
Best for: Owners of Hayward or Maytronics robotic cleaners seeking ultra-fine filtration and reusable options.
Not ideal for: Users with infrequent pool cleaning needs or those seeking disposable, low-maintenance filters.
- Compatibility:Hayward TigerShark, SharkVac, AquaVac 500 series, Maytronics RCX70101PAK2, RCX70101

- Filter Type:Ultra-fine, diamond-shaped grid
- Reusability:Yes
- Lasts:2-3 years with proper maintenance

Dolphin Filters 9991432-R4 Replacement Pool Filter (4 Pack) for Dolphin M400/M500, Nautilus CC Plus
This set is tailored for Dolphin M400, M500, and Nautilus CC Plus models, featuring a three-layer diamond grid that enhances impact resistance and filtration. Compared with the ultra-fine filters, these offer more robust construction, ideal for environments with tougher debris or frequent use. The filters are made with enhanced PET fiber, ensuring better filtration performance. However, they are limited to specific Dolphin models and lack detailed lifespan data, which might be a concern for those wanting long-term replacements without frequent checks. This product suits Dolphin owners who prioritize durability and impact resistance over ultra-fine filtration.
Pros:- Compatible with popular Dolphin robotic cleaners
- Enhanced PET fiber improves filtration
- Three-layer diamond grid increases impact resistance
- Includes four filters for convenience
Cons:- Limited to specific Dolphin models
- No detailed filter lifespan info
- Less suited for small particle filtration compared to ultra-fine types

Not ideal for: Owners of older Dolphin models or those seeking ultra-fine filtering for very small particles.
- Product Dimensions:6 x 3 x 2 inches
- Item Weight:15.2 ounces
- Part Number:9991432-R4
Our verdict“Best for Dolphin users seeking a durable, impact-resistant filter that withstands tougher debris, though it’s less ideal for ultra-fine particle removal.”
Ultra Fine Filters Compatible with Dolphin Nautilus CC Plus, Nautilus CC Supreme, M200/M400/M500 – 4 Pack
This set offers ultra-fine pleated filters designed to target tiny particles, making it ideal for pool owners who want a crystal-clear experience. Made from heavy-duty ABS plastic, these filters are built for durability, lasting 2-3 years with good maintenance—comparable to the Dolphin impact-resistant options but with a focus on small particle filtration. Compared to the previous impact-resistant filters, these excel at fine filtering but are less suited for heavy debris or impact-heavy environments. Regular rinsing every 4-6 weeks is necessary to sustain performance, which might be a consideration for busy pool owners. This choice makes the most sense for those prioritizing ultra-fine particle removal and long-term durability.
Pros:- Highly effective at removing small particles
- Durable construction with a 2-3 year lifespan
- Cost-effective pack of four filters
Cons:- Not compatible with older models or Triton series
- Requires regular rinsing for optimal performance
Best for: Owners of Dolphin models who want to maximize small particle filtration and long-lasting filters with minimal replacements.
Not ideal for: Those dealing with heavy debris or seeking impact-resistant filters for rougher pools.
- Compatibility:Nautilus CC Plus, Nautilus CC Supreme, M200, M400, M500
- Part Number:9991432-R4
- Size:10-1/2″ (L) x 6-3/8″ (W)

Pool Replacement Filter Compatible with Hayward RCX70101PAK2
This filter is designed specifically for Hayward TigerShark models, featuring a three-piece filter assembly with a plastic frame that facilitates quick replacement and cleaning. It’s a good choice for those who want a straightforward, effective filter for seasonal or annual updates. Compared with the reusable ultra-fine options, this filter is simpler to replace and clean, but it may not last as long under heavy debris conditions. The plastic frame, while lightweight, might be less durable over time, especially in harsher environments. Nonetheless, it provides reliable filtration for regular use with minimal fuss. This product suits Hayward owners seeking a practical, easy-to-replace filter for routine maintenance.
Pros:- Effective at filtering dirt and debris
- Easy to replace and clean
- Compatible with multiple Hayward TigerShark models
Cons:- Requires frequent replacement depending on debris level

- Product Dimensions:11.5 x 8.65 x 0.78 inches
- Item Weight:9.1 ounces
- Part Number:RCX70101
- Compatible Models:Tiger Shark rc9990gr, rc36000qc, rc9950, rc9952, rc9742, rc4702, w3rc9740cub, Sharkvac rc9740
Our verdict“Best for Hayward TigerShark owners needing a straightforward, easy-to-replace filter for regular maintenance, with some durability tradeoffs.”
2 Set Ultra Fine Filter Basket for Dolphin M600, Explorer E30, Active 20
This set stands out for its broad compatibility across multiple Dolphin models like the M600, Explorer E30, and Active 20, making it a flexible choice for owners with several Dolphin cleaners. Compared to the Dolphin Filters 9991432-R4, which focus on specific models, this set offers a more universal fit and includes both a complete filter basket and replacement panels, providing a comprehensive solution. The high-fiber pleated fabric enhances filtration efficiency, trapping finer debris such as mud and sediment, which is ideal for pools with heavy dirt. Its durable ABS frame ensures long-term use, and the ease of installation without tools saves time during maintenance. However, the need for rinsing every 4-6 weeks and panel replacements every 2-3 years introduces ongoing upkeep. This pick is best suited for pool owners seeking a durable, multi-model compatible filter that balances long-term performance with manageable maintenance.
Pros:- Compatible with a wide range of Dolphin models, reducing the need for multiple types
- Durable, washable filter material with high filtration efficiency
- Easy to install without tools, saving time during setup
Cons:- Requires rinsing every 4-6 weeks for optimal performance, which may be frequent for some users
- Replacement panels need to be replaced every 2-3 years, adding ongoing costs
Best for: Homeowners with multiple Dolphin robotic cleaners or those who prioritize high filtration efficiency and durability.
Not ideal for: Owners with very infrequent pool use or minimal debris, since rinsing every few weeks might be unnecessary for light cleaning needs.
- Compatibility:Dolphin Robotic Pool Cleaners (Active 20, M600, Explorer E30, and more)
- Replacement Part Numbers:9991458-R1, 9991467-R4
- Material:ABS plastic frame, high-fiber pleated fabric
- Includes:1 complete filter basket, 4 replacement panels

Our verdict“This set is ideal for owners who want a versatile, long-lasting filter that keeps their pool clean across multiple Dolphin models.”
Pool Cleaner Spring Filters for Dolphin Nautilus, Triton, DX6, Wave 75, Edge, Quest, Discovery (Old), Prowler 830 – 4 Pack
Compared with the Ultra Fine Filter Basket for Dolphin M600, the Spring Filters focus on quick, straightforward debris removal for popular Dolphin models like Nautilus and Triton. They are a straightforward solution, especially for pool owners who prefer simple, quick swaps rather than detailed maintenance routines. While they effectively trap dirt and debris, their rinsing frequency—monthly—may be less demanding than the more sophisticated filters, making them suitable for pools with moderate debris. The four-pack offers extended value, reducing the need for frequent repurchasing. Nonetheless, the lack of specific durability info means they might not last as long as more premium filters, and they are limited strictly to replacement rather than offering enhanced filtration features. This product makes the most sense for budget-conscious users who prioritize easy, frequent replacements over long-term durability.
Pros:- Compatible with multiple Dolphin models, including Nautilus and Prowler 830
- Includes four filters, providing good value for ongoing replacements
- Effective at trapping dirt and debris, maintaining pool cleanliness
Cons:- Requires rinsing monthly, which may be inconvenient for some users
- No specific durability or material longevity information provided
Best for: Pool owners seeking affordable, easy-to-replace filters for Dolphin models like Nautilus and Prowler 830, especially if they prefer quick swaps over detailed maintenance.
Not ideal for: Owners with heavily debris-laden pools or those wanting filters with extended lifespan, since rinsing is needed monthly and durability info is limited.
- Fit for:Dolphin Nautilus, Triton, DX6, Wave 75, Edge, Quest, Discovery (Old), Prowler 830
- Filter Dimensions:10.9″ x 5.2″
- Pack Count:4
Our verdict“This pack suits budget-minded pool owners who want straightforward, quick-to-replace filters for regular debris removal in Dolphin models.”
How We Picked
These products were evaluated based on their compatibility with popular pool cleaner models, filtration efficiency, build quality, and value for money. We prioritized filters that fit a range of models but also included some specific to top brands like Dolphin and Hayward. Durability and ease of installation were key factors, along with customer feedback on performance and longevity. Our ranking balances performance with affordability, helping buyers find options suited to different budgets and needs.Factors to Consider When Choosing Replacement Filters For Automatic Pool Cleaners
When selecting replacement filters for automatic pool cleaners, understanding the key factors can help you make a smarter choice. Compatibility is the most important aspect; ensure the filter matches your specific cleaner model to prevent leaks or poor filtration. Filtration efficiency, especially ultra-fine capabilities, directly impacts water clarity, but these filters may require more frequent changes. Consider the build quality and material durability, as higher-quality filters often last longer and save money over time. Price is another factor—sometimes paying more upfront results in fewer replacements and better performance. Finally, check if bulk packs are available, which can be more economical for regular replacements.Compatibility and Fit
Ensuring the filter matches your specific pool cleaner model is essential for effective operation. Even minor mismatches can cause leaks or reduced filtration performance. Always verify model numbers and compatibility details before purchasing. Some filters are designed for a range of models, which can simplify selection, but always double-check fit to avoid costly mistakes.Filtration Quality
The main purpose of replacement filters is to improve water clarity by trapping dirt, debris, and fine particles. Ultra-fine filters excel at capturing smaller contaminants, resulting in cleaner water but potentially requiring more frequent replacements. Balancing filtration efficiency with replacement frequency is key—premium filters usually offer better performance and longer lifespan.Durability and Material
Filters made from high-quality, durable materials withstand the wear and tear of frequent use. Cheaper options may fall apart or clog quickly, leading to more replacements and higher long-term costs. Investing in well-made filters can save money and effort over time, especially for regular pool maintenance.Price and Value
While cheaper filters might seem appealing initially, they often require more frequent replacements, increasing costs over time. Bulk packs or multi-packs often provide better value, especially for frequent users. Consider your budget and how often you plan to replace filters to determine the best balance of cost and performance.Ease of Installation and Maintenance
Filters that are straightforward to install and remove can save time and frustration. Look for models with simple clip or screw-on mechanisms. Additionally, some filters are easier to clean, which can extend their lifespan and improve overall cleaning performance.Frequently Asked Questions
How often should I replace my pool cleaner filters?
The frequency of replacement depends on usage, water quality, and filter type. Ultra-fine filters tend to clog faster and may need replacement every 2-4 weeks with regular use, while standard filters can last longer. Regular inspection and cleaning can extend their life, but if you notice decreased suction or water flow, it’s time for a new filter. Following your manufacturer’s recommendations and monitoring performance are best practices to keep your cleaner operating efficiently.
Can I use filters designed for one brand of pool cleaner on another?
While some filters are compatible across multiple brands, most are designed specifically for certain models or brands. Using incompatible filters may cause poor fit, leaks, or reduced filtration. Always check the compatibility details before purchase. If in doubt, consult your cleaner’s manual or manufacturer to find suitable replacements that meet the required specifications.
Are ultra-fine filters worth the extra cost?
Ultra-fine filters are particularly effective at capturing tiny particles, leading to clearer water and better overall pool hygiene. However, they tend to clog faster and may require more frequent cleaning or replacement, which can add to maintenance costs. For pools with high debris levels or those requiring pristine water quality, ultra-fine filters can be a worthwhile investment. For less demanding conditions, standard filters may suffice and offer better value.
Should I buy filters in bulk or individual packs?
Buying filters in multi-packs or bulk sets generally offers better value, especially if you replace filters regularly. Bulk options reduce per-unit costs and prevent last-minute shopping. However, ensure the filters are compatible with your cleaner and of good quality, as cheaper bulk packs sometimes compromise on durability or fit. If you only replace filters infrequently, individual packs might be more economical and reduce waste.
What are the signs that my filter needs replacing?
Common signs include decreased water flow from the cleaner, longer cleaning times, or visible debris bypassing the filter. A noticeable reduction in suction or the cleaner struggling to pick up debris indicates that the filter may be clogged or worn out. Regular inspections and cleaning can help extend filter life, but if performance drops despite maintenance, replacing the filter is usually the best step to restore efficiency.
Conclusion
For most users, the 4 Pack Pool Filter Cartridges for Hayward Sharkvac RCX70101PAK2 offers reliable performance and great value, making it the best overall choice. Budget-conscious buyers will find the Replacement Robotic Pool Cleaner Filter Cartridges, Ultra Fine a cost-effective solution without sacrificing too much filtration quality. If you prefer premium durability and top-tier filtration, the Dolphin Filters 9991432-R4 suits dedicated pool owners. Beginners or casual users should prioritize ease of installation and affordability, while those with high-performance needs should consider ultra-fine or bulk packs to ensure consistent clarity. Ultimately, your choice depends on your pool size, debris load, and maintenance preferences.
