The best pool cleaner replacement filter depends on your cleaner model and the debris you need to catch. My best overall pick is the Ulticor Ultra Fine Filter Basket for Dolphin, which offers a basket-style option for compatible Dolphin cleaners. For value, the Spring Filter Cartridges for Dolphin Nautilus CC Plus, M400, M500 come as a four-pack, while the 3µm Aiper Scuba S1 inserts suit owners seeking very fine filtration for a specific model. The main tradeoffs are exact fit, filter fineness, cleaning effort, and how many replacements come in a pack. Read on for all 13 options and guidance on matching a replacement to your cleaner.

Key Takeaways
- Exact model fit matters more than a broad brand match: the lineup separates Dolphin, Hayward, Polaris, Aiper, and WYBOT filters into distinct model families.
- Dolphin owners have the widest choice here: options range from an Ulticor basket to ultra-fine panels and multi-cartridge packs, so check the cleaner model and filter format before choosing.
- Pack size changes the value calculation: several Dolphin options and the Hayward cartridges come in four-packs, while the Polaris and Aiper options are sold as two-packs.
- Fine filtration is a specialized choice: the Aiper inserts specify 3µm filtration, but finer capture may call for more frequent cleaning than a less restrictive filter.
- Cleaner type shapes replacement needs: Polaris pressure-side cleaners use bags, while the robotic cleaner options use baskets, cartridges, panels, or sponges.

More Details on Our Top Picks
Nylon Mesh Pool Cleaner Bag for Polaris 280 & 480
This replacement bag makes the most sense when your cleaner is a Polaris 280 or 480 and you mainly need to collect leaves, small twigs, and everyday debris. Its wide zipper opening gives you room to empty the bag without wrestling debris through a narrow opening, while the enhanced clip is intended to hold the bag securely during cleaning. Compared with the 2 Pack Zippered Bag Replacement Fits for Polaris 360, 380 Pool Cleaner, this is the model-specific choice for 280 and 480 owners; the other bag is not listed as compatible with those models. The tradeoff is that this is a single bag with no supplied dimensions or micron rating, so buyers seeking a multi-pack or a defined fine-filtration level should look elsewhere. It also needs replacement if the mesh tears.
Pros:- Nylon mesh is suited to collecting leaves and small twigs.
- Wide zipper opening makes debris removal easier.
- Enhanced clip is designed for a secure fit.
- Strong stitching supports repeated use.
Cons:- Compatibility is limited to Polaris 280 and 480 models.
- The listing gives no size or filtration-micron specifications.
- A torn mesh bag needs replacement rather than repair.
Best for: Polaris 280 or 480 owners who want a reusable mesh bag for leaves and small twigs and value easy emptying.
Not ideal for: Owners of Polaris 360, 380, or other cleaner models, or buyers who need a stated micron rating or multiple replacement bags.
- Material:Nylon mesh
- Compatibility:Polaris 280 and 480
- Debris use:All-purpose collection, including leaves and small twigs
- Opening:Wide zipper opening
- Attachment:Enhanced clip
- Construction:Strong stitching
Our verdict“Choose this bag for a Polaris 280 or 480 when secure attachment and easy emptying matter more than a multi-pack or specified fine filtration.”
Replacement Robotic Pool Cleaner Filter Cartridges, Ultra Fine, for Hayward Robotic AquaVac, TigerShark, and SharkVac
For owners of compatible Hayward robots, this two-cartridge set pairs a rigid ABS frame with PET fiber mesh for reusable, ultra-fine filtration. That construction is a better match for catching finer dirt than the Spring Filter Cartridges for Dolphin Nautilus CC Plus, M400, M500, which are described as trapping larger debris. The practical benefit is a closer fit for pool owners who want their robot to collect smaller particles rather than focus mainly on leaves and larger material. Compatibility covers TigerShark, SharkVac, and AquaVac series, but the listing does not claim it fits every Hayward model, so checking the exact cleaner is essential. The cartridges also need regular rinsing—about every four to six weeks—and their stated two-to-three-year lifespan depends on maintenance and use.
Pros:- Ultra-fine PET fiber mesh targets smaller dirt and debris.
- ABS plastic frame is described as durable and impact-resistant.
- Reusable design can serve for two to three years with proper care.
- Two cartridges are included.
Cons:- Fit is limited to compatible Hayward models and must be checked.
- Regular cleaning is recommended every four to six weeks.
- Lifespan varies with use and maintenance.
Best for: Hayward TigerShark, SharkVac, or AquaVac owners seeking reusable cartridges for finer dirt and debris.
Not ideal for: Owners of Dolphin or other non-listed robots, and buyers who prefer a low-maintenance filter that needs infrequent cleaning.
- Part number:RCX70101PAK2
- Compatibility:Hayward TigerShark, SharkVac, and AquaVac series
- Frame material:ABS plastic
- Mesh material:PET fiber
- Dimensions:12.2 x 6.97 x 1.65 inches
- Weight:11.7 ounces
- Package quantity:2 cartridges
- Filter type:Ultra fine
Our verdict“Pick this two-pack if your Hayward robot is confirmed compatible and finer particle capture matters more than less frequent filter upkeep.”
Spring Filter Cartridges for Dolphin Nautilus CC Plus, M400, M500 – 4 Pack
This four-cartridge set suits Dolphin owners who want replacement capacity on hand and primarily need to trap larger debris. The screen material is described as helping prevent clogging, while the ABS frames are reusable with regular cleaning. Compared with the Ulticor Ultra Fine Filter Basket for Dolphin Robotic Pool Cleaners, this set is positioned for larger debris rather than microfiltration, making it a more straightforward match when leaves and similar material are the priority. Its compatibility list spans several Dolphin models, including Nautilus CC Plus, M400, and M500, but the product specifically excludes models such as Nautilus CC and M600. That model dependence is the main buying risk: confirm your cleaner before ordering. Rinsing every four to six weeks is also part of keeping the cartridges working as intended.
Pros:- Four cartridges provide replacements to keep on hand.
- Compatible with a range of listed Dolphin cleaners.
- ABS frames support reuse with proper cleaning.
- Screen design targets larger debris and helps limit clogging.
Cons:- Not suitable for some Dolphin models, including Nautilus CC and M600.
- Designed for larger debris rather than ultra-fine filtration.
- Regular rinsing every four to six weeks is recommended.
Best for: Dolphin Nautilus CC Plus, M400, or M500 owners who want four reusable cartridges for collecting larger debris.
Not ideal for: Buyers seeking ultra-fine filtration, or owners of excluded Dolphin models such as Nautilus CC or M600.
- Compatibility:Dolphin Nautilus CC Plus, M400, M500, M4, M5, Wave 65, Wave 90, and other listed models
- Material:ABS plastic and screen material
- Dimensions:10.5 x 6.375 inches
- Quantity:4 cartridges
- Filter purpose:Traps larger debris
- Care:Regular rinsing recommended
- Stated reusable lifespan:Two to three years with proper cleaning
- Excluded models:Nautilus CC and M600
Our verdict“Choose this four-pack for a compatible Dolphin cleaner when larger debris capture and spare cartridges matter more than fine-particle filtration.”
Ulticor Ultra Fine Filter Basket for Dolphin Robotic Pool Cleaners
The Ulticor basket stands apart from the spring-cartridge four-pack because it is built around microfiltration, not simply replacement quantity or larger-debris capture. That makes it the more suitable choice for compatible Dolphin owners focused on fine debris. Its compatibility list is broad, spanning models such as S50, S100, Active 10, T25, E10, and Nautilus CC, though it explicitly excludes Nautilus CC Pro and Nautilus CC Supreme. The basket is also an aftermarket part, so the long compatibility list should not replace checking the exact model and fit. Some cleaners may require removal of a plastic piece for proper installation, adding a step that the Spring Filter Cartridges for Dolphin Nautilus CC Plus, M400, M500 do not call out. Regular rinsing every four to six weeks is recommended, and the listing’s capacity figures are not a measure of filtration fineness.
Pros:- Microfiltration design targets fine debris.
- Compatibility list covers many Dolphin models.
- Basket format is easy to rinse for routine care.
- Manual, self-propelled cleaner use requires no separate power source for the filter.
Cons:- Not compatible with Nautilus CC Pro or Nautilus CC Supreme.
- Some models may need a plastic piece removed for fit.
- Regular rinsing every four to six weeks is recommended.
Best for: Dolphin owners of a listed compatible model who want an aftermarket basket aimed at fine-debris capture.
Not ideal for: Nautilus CC Pro or CC Supreme owners, and buyers who want a direct-fit part without possible plastic-piece removal.
- Compatibility:Dolphin 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, and Nautilus CC
- Not compatible with:Nautilus CC Pro and Nautilus CC Supreme
- Material:Plastic
- Dimensions:9.1 x 5.3 x 7.1 inches
- Item weight:0.87 kg
- Load capacity:0.87 kg
- Power source:Manual
- Filtration type:Ultra fine microfiltration
Our verdict“Select this basket if your Dolphin model is listed and fine-debris capture outweighs the fit caveats of an aftermarket replacement.”
2 Pack Zippered Bag Replacement Fits for Polaris 360, 380 Pool Cleaner
This two-pack is a practical replacement choice for Polaris 360 and 380 owners who want one bag in use and another available. Its nylon mesh is specified to filter down to 120 microns, and the zipper makes the bag easier to empty than a closure-free design. That stated micron support gives buyers more filtration detail than the Nylon Mesh Pool Cleaner Bag for Polaris 280 & 480, but the model fit runs the other way: this set is for 360 and 380 cleaners, not 280 or 480. The bags are described as durable and strongly stitched, though no expected service life is provided. The listed weight is just 0.01 ounces, which may be a data error, so I would not use it to judge sturdiness. Verify the cleaner model before ordering.
Pros:- Two replacement bags are included.
- Compatible with Polaris 360 and 380 cleaners.
- Nylon mesh supports filtration down to 120 microns.
- Zipper opening simplifies emptying and cleaning.
Cons:- Not compatible with Polaris 280, 480, or 180 models.
- Listed weight of 0.01 ounces may be inaccurate.
- No expected replacement interval is provided.
Best for: Polaris 360 or 380 owners who want two zippered mesh bags and a stated filtration level for small debris.
Not ideal for: Polaris 280, 480, or 180 owners, or buyers who need reliable published weight and service-life details.
- Compatibility:Polaris 360 and 380
- Material:Nylon mesh
- Micron support:Down to 120 microns
- Package quantity:2 bags
- Opening:Zippered
- Product dimensions:5.2 x 4.7 x 3.4 inches
- Listed item weight:0.01 ounces
- Construction:Strong stitching
Our verdict“Buy this two-pack for a Polaris 360 or 380 when the 120-micron specification and spare bag are useful, after confirming your model.”
M400 Ultra Fine Cartridge Filter Replacement for Dolphin Nautilus CC Plus
For owners of several supported Dolphin cleaners, this four-cartridge set covers the Nautilus CC Plus, M200, M400, and M500, giving it broader listed compatibility than the M400/M500-specific Replacement Pool Filter Cartridge for Dolphin M400/M500 and Nautilus CC Plus. Its super-fine filter paper is intended to catch debris, leaves, and hair, while the heavy-duty ABS frame provides a rigid cartridge structure. The tradeoff is a strict compatibility boundary: it does not fit the Nautilus CC, so checking the exact cleaner model matters before ordering. The product information also recommends rinsing every four to six weeks, adding upkeep that buyers seeking less frequent maintenance may not want. I’d choose it over the Aiper 3µm basket insert when a supported Dolphin model is the priority, not when a stated micron rating is required.
Pros:- Listed compatibility spans four Dolphin cleaner models.
- Super-fine filter paper is designed to trap debris, leaves, and hair.
- Heavy-duty ABS plastic provides a rigid cartridge frame.
- Four filters provide spares for continued rotation.
Cons:- Does not fit the Dolphin Nautilus CC.
- Requires regular rinsing, with the supplied guidance calling for cleaning every four to six weeks.
- No micron rating is provided for comparing filtration fineness.
Best for: Owners of a Dolphin Nautilus CC Plus, M200, M400, or M500 who want four fine-filter cartridges in one set.
Not ideal for: Nautilus CC owners or buyers who need a filter with a stated micron rating or less frequent rinse maintenance.
- Compatible models:Dolphin Nautilus CC Plus, M200, M400, and M500
- Frame material:Heavy-duty ABS plastic
- Filter media:Super-fine pet filter paper
- Dimensions:10.5 x 6.38 inches
- Package quantity:4 filters
- Excluded model:Dolphin Nautilus CC
- Suggested rinse interval:Every 4–6 weeks
Our verdict“Choose this four-pack if you own one of its listed Dolphin models and want fine filtration with broader model coverage than the M400/M500-focused alternative.”
Replacement Pool Filter Cartridge for Dolphin M400/M500 and Nautilus CC Plus (4 Pack)
This cartridge set is a focused alternative for Dolphin Nautilus CC Plus, M400, and M500 owners who favor a reinforced media design. Its three-layer diamond grid and enhanced PET fiber are described as improving filtration and impact resistance, a different emphasis from the super-fine filter paper in the M400 Ultra Fine Cartridge Filter Replacement. Both options include four cartridges, but this one does not list the M200 as compatible, so the wider model coverage belongs to the other set. The product details also omit a micron rating and a recommended replacement interval; buyers who want a measurable fineness target or clear maintenance guidance may prefer another option. I’d put this ahead of the Aiper Scuba S1 insert only for owners whose cleaner matches its narrower Dolphin compatibility list.
Pros:- Three-layer diamond-grid design is intended to improve impact resistance.
- Enhanced PET fiber provides a defined filter-media construction.
- Four cartridges are included.
- Fits three listed Dolphin cleaner models.
Cons:- Does not list the Dolphin M200 as compatible.
- Not compatible with Nautilus CC or Nautilus CC Pro models.
- No lifespan, replacement schedule, or micron rating is provided.
Best for: Nautilus CC Plus, M400, and M500 owners seeking a four-pack with PET media and a reinforced grid structure.
Not ideal for: Dolphin M200 or Nautilus CC and CC Pro owners, and buyers who require a stated micron rating or service interval.
- Compatible models:Dolphin M400, M500, and Nautilus CC Plus
- Filter media:Enhanced PET fiber
- Media design:Three-layer diamond grid
- Product dimensions:6 x 3 x 2 inches
- Item weight:15.2 ounces
- Part number:9991432-R4
- Package quantity:4 cartridges
Our verdict“Pick this set over the broader-coverage Dolphin cartridge when your cleaner is an M400, M500, or Nautilus CC Plus and the reinforced PET-grid construction is your priority.”
2-Pack 3µm Filter Basket Insert for Aiper Scuba S1 Pool Cleaner
The standout here is a clearly stated 3 µm filtration size, making this insert the most specific choice in this group for Scuba S1 owners targeting microscopic debris. Its snap-in installation needs no tools, unlike the Polaris 280/480 replacement bag, which uses a different cleaner system and a bag-style filter. The set includes two inserts, but not the white frame, so buyers must already have a compatible basket support rather than expecting a complete filter assembly. Compatibility is also narrow: it fits the Aiper Scuba S1, not the S1 Pro. Compared with the Aiper Scuba V3/S3 3µm filters, this option serves a different cleaner family, so the micron rating alone should not guide the choice. Check the exact model and frame needs first.
Pros:- Stated 3 µm filtration targets microscopic debris.
- Snap-in installation requires no tools.
- Silicone edging is described as durable.
- Two inserts provide a spare.
Cons:- Not compatible with Aiper Scuba S1 Pro.
- White frame is not included.
- Compatibility is limited to the Scuba S1.
Best for: Aiper Scuba S1 owners who want a stated 3 µm filter insert and already have the required basket frame.
Not ideal for: Scuba S1 Pro owners or buyers who need a replacement frame included with the filter.
- Compatibility:Aiper Scuba S1; not S1 Pro
- Filter size:3 µm
- Package quantity:2 inserts
- Frame included:No
- Installation:Snap-in; no tools required
- Edge material:Silicone
Our verdict“Choose this insert for a Scuba S1 when fine particle capture matters and you already own the compatible basket frame.”
Pool Cleaner Replacement Filter Bag Fits for Polaris 280 and 480
Unlike the cartridge and basket inserts elsewhere in this roundup, this is a reusable nylon mesh bag for Polaris 280 and 480 cleaners. Its main practical draw is the chemical-resistant zipper, paired with a two-step installation and a secure fit, giving these Polaris owners a bag-style replacement rather than a cartridge to rinse and reinstall. That makes it a more relevant match than either Aiper 3µm filter, but it offers no stated micron rating or special fine-filtration feature. Buyers focused on capturing microscopic debris have clearer filtration information from the Aiper options; this bag’s appeal is its reusable mesh construction and model-specific fit. Compatibility is limited to the Polaris 280 and 480, so owners of other Polaris models should not assume the dimensions alone guarantee a match.
Pros:- Reusable nylon mesh construction.
- Zipper is described as resistant to corrosion from pool chemicals.
- Two-step installation is designed to be straightforward.
- Listed fit covers Polaris 280 and 480 cleaners.
Cons:- Compatibility is limited to Polaris 280 and 480.
- No micron rating or additional filtration detail is provided.
- Bag format is not interchangeable with the cartridge and basket inserts in this roundup.
Best for: Polaris 280 or 480 owners replacing a reusable mesh filter bag and prioritizing a secure, chemical-resistant zipper.
Not ideal for: Owners of other Polaris models or buyers seeking a stated fine-particle filtration rating.
- Compatible models:Polaris 280 and 480
- Material:Nylon mesh
- Dimensions:2.7 x 9.8 x 13.3 inches
- Item weight:6.7 ounces
- Zipper:Resistant to corrosion
- Filter format:Reusable bag
- Installation:Two-step installation
Our verdict“Choose this bag if your cleaner is a Polaris 280 or 480 and you want a reusable mesh replacement rather than a cartridge-style filter.”
2-Pack Ultra-Fine 3µm Replacement Filters for Aiper Scuba V3 & Scuba S3 Robotic Pool Cleaners
For owners of the Aiper Scuba V3 or Scuba S3, this set pairs 3µm ultra-fine filtration with tool-free replacement. That gives it a clear fineness specification, much like the Scuba S1 basket insert, but the models do not overlap: this pair is listed for V3 and S3 cleaners, while the other Aiper option is for the Scuba S1. The main catch is that the filter basket support frame is sold separately, so these filters are not a complete frame-and-media replacement. Two filters are included, and their listed dimensions and weight provide more handling detail than the S1 insert’s supplied specs. Buyers should also note the stated incompatibility with Gosvor Pool Vacuum LiteVac G1. Choose by cleaner model first; the shared micron rating does not make these parts interchangeable.
Pros:- 3µm filtration is specified for targeting fine debris.
- Tool-free replacement simplifies filter changes.
- Two replacement filters are included.
- Listed compatibility clearly covers Scuba V3 and Scuba S3.
Cons:- Basket support frame is sold separately.
- Not compatible with the Aiper Scuba S1 or Gosvor LiteVac G1.
- Limited to the specified cleaner models.
Best for: Aiper Scuba V3 or Scuba S3 owners who want a stated 3µm filter and already have the basket support frame.
Not ideal for: Scuba S1 owners, LiteVac G1 owners, or anyone who needs the support frame included.
- Compatibility:Aiper Scuba V3 and Scuba S3 cordless robotic pool cleaners
- Filter size:3µm ultra-fine filtration
- Package quantity:2 filters
- Product dimensions:12.2 x 4.72 x 0.87 inches
- Item weight:4.2 ounces
- Installation:Tool-free replacement
- Support frame:Sold separately
- Listed incompatibility:Gosvor Pool Vacuum LiteVac G1
Our verdict“Choose this two-pack for a Scuba V3 or S3 only if you have the separate support frame and want a stated 3µm replacement filter.”
8 pcs Filter Sponges for WYBOT A1 Robotic Pool Cleaner Replacement Filters
This eight-piece set is the most straightforward choice here for owners of the WYBOT A1: the cotton-foam sponges are designed for that cleaner and can be rinsed and reused, giving you replacements ready when a filter needs cleaning. Compared with the Ultra-Fine Filter Panels for Dolphin Robotic Pool Cleaner, this set does not claim fine-particle filtration or broad model compatibility; its appeal is simple upkeep for one specific cleaner. The product information also gives no filtration rating or capacity, so I would not choose it based on a need to capture a particular particle size. Its WYBOT-only fit is the main limitation, and regular rinsing remains part of keeping performance up. For A1 owners who want spare washable sponges rather than a more specialized panel, the eight-count pack is a practical match.
Pros:- Designed specifically for the WYBOT A1
- Eight sponges provide several replacements on hand
- Cotton foam can be rinsed and reused
- Described as easy to install and clean
Cons:- Not compatible with other listed cleaner models
- No filtration capacity or particle-size rating is provided
- Regular cleaning is needed to maintain performance
Best for: WYBOT A1 owners who want a supply of reusable replacement sponges they can rinse between cleaning cycles.
Not ideal for: Owners of other robotic pool cleaners, or buyers who need a stated fine-particle filtration rating before choosing a filter.
- Material:Cotton foam
- Quantity:8 pieces
- Dimensions:9 x 0.3 x 9 inches
- Item weight:3.17 ounces
- Compatible model:WYBOT A1
- Filter type:Replacement filter sponge
Our verdict“Choose this set if you own a WYBOT A1 and want multiple washable sponge replacements, but skip it if you need broader compatibility or specified fine filtration.”
Ultra-Fine Filter Panels for Dolphin Robotic Pool Cleaner – 4 Pack
These panels are the stronger fit when a compatible Dolphin cleaner needs to catch fine dirt and debris, rather than simply replace a general-purpose filter. Their pleated design and stated compatibility with several Dolphin models give them a different role from the 8 pcs Filter Sponges for WYBOT A1, which are washable foam sponges for one cleaner model and have no stated filtration rating. This pack is a direct replacement for part 9991467-R4, and numbered panels help with correct placement during installation. You can rinse and reuse them, though regular cleaning is still required, and the product data does not list a particle-size rating. Model fit is specific, so check your Dolphin’s part compatibility before buying; owners with frequent replacement needs may also find four panels insufficient as a long-term supply.
Pros:- Pleated panels are described as capturing fine dirt and debris
- Direct replacement for part 9991467-R4
- Numbered panels help guide placement
- Reusable and hose-rinsable
Cons:- Fits only certain Dolphin models
- Requires regular cleaning to maintain filtration performance
- Four panels may not cover frequent replacement needs
Best for: Dolphin robotic cleaner owners whose compatible model uses part 9991467-R4 and who want reusable pleated panels for fine debris.
Not ideal for: Owners of WYBOT, Hayward, or other non-compatible cleaners, and buyers who need a stated micron rating or a larger replacement supply.
- Quantity:4 panels
- Filter type:Pleated ultra-fine filter panels
- Replacement part:9991467-R4
- Model number:FP-001
- Product dimensions:9 x 8 x 2.5 inches
- Item weight:1.15 pounds
- Maintenance:Reusable; clean with a garden hose
Our verdict“Pick these panels for a compatible Dolphin cleaner when fine-debris capture matters more than universal fit or a larger pack.”
4 Pack Hayward Sharkvac RCX70101PAK2 Pool Filter Cartridges for Robotic Pool Cleaners
This cartridge set makes the most sense for Hayward owners who want one replacement option covering a range of listed cleaners, including TigerShark, SharkVac, and AquaVac 500 Series models. Its three-layer PET-fiber construction is described as durable and impact resistant, giving it a sturdier filtration format than the WYBOT A1 cotton-foam sponges. The four-cartridge pack also leaves spares available, though the product data does not specify service life or a particle-size rating. Compatibility remains firmly within the listed Hayward families, so this is not a cross-brand substitute for the Dolphin panels in this roundup. Maintenance calls for rinsing and periodic soaking, adding more care than a quick rinse alone. I would choose it for model-matched Hayward coverage and cartridge construction, not for buyers seeking quantified fine-filtration performance.
Pros:- Compatible with several listed Hayward cleaner families
- Three-layer PET-fiber design is described as durable and impact resistant
- Four cartridges provide spares for replacement rotation
- Designed for straightforward replacement and maintenance
Cons:- Compatibility is limited to specified Hayward models
- No lifespan information is provided
- Rinsing and periodic soaking add maintenance
Best for: Hayward robotic cleaner owners with a listed TigerShark, SharkVac, or AquaVac model who want four replacement cartridges in one set.
Not ideal for: Owners of Dolphin or WYBOT cleaners, or buyers who need a published filtration rating or cartridge lifespan.
- Model number:RCX70101PAK2
- Quantity:4 cartridges
- Compatible models:TigerShark, TigerShark QC, TigerShark Plus, TigerShark2, TigerShark2 Plus, SharkVac XL, SharkVac, Aqua Vac 500 Series

How We Picked
I compared these pool cleaner replacement filters by the factors most likely to affect a purchase: stated compatibility, filter format, debris-capture claims, pack quantity, and the likely upkeep involved. Exact model fit received the most weight because a filter that does not seat correctly cannot do its job. I also separated bags for Polaris pressure-side cleaners from cartridge, basket, panel, and sponge replacements for robotic cleaners rather than treating them as interchangeable.
The ranking favors options with a clear use case and useful buyer tradeoffs, not a single filtration claim. Multi-packs rise when they offer a practical replacement supply for a named cleaner family, while highly specific inserts rank for owners who need that exact fit. I did not infer compatibility beyond the product names provided, so buyers should verify their cleaner’s model and existing filter shape before ordering.

Factors to Consider When Choosing Pool Cleaner Replacement Filters
Before choosing a replacement, start with the cleaner itself rather than the filter’s advertised fineness. A filter can look similar and still have the wrong attachment, dimensions, or fit for your machine. These broader checks can help prevent a mismatch and set realistic expectations for cleaning and upkeep.
Match the cleaner model and filter format
Find the cleaner’s full model name or number on its label or in its manual before shopping. Brand alone is not enough: a Dolphin cartridge is not automatically a fit for every Dolphin cleaner, and the lineup includes model-specific AquaVac, Nautilus, M-series, Polaris, Aiper, and WYBOT options. Check whether your cleaner takes a bag, a rigid basket, panels, cartridges, or foam sponges. Compare the replacement’s shape and attachment points with the part you are removing. If the listing names only a broad family, verify that your exact model is included rather than assuming. This simple check matters more than choosing the finest filtration rating.
Choose filtration for the debris you actually collect
Think about what regularly reaches the cleaner: leaves and larger debris call for a different balance than very fine dust or sediment. The Aiper Scuba S1 and Scuba V3/S3 options specify 3µm filtration, which gives those models a clearly fine-filtering choice in this roundup. That specification does not prove every fine filter will suit every pool or cleaner. Finer media can load with debris sooner and may need more frequent rinsing, so it can add upkeep. If your pool mainly collects large debris, a very fine replacement may add maintenance without a meaningful benefit. Use your current filter’s performance and the debris left behind as guides.
Weigh pack size against replacement frequency
A multi-pack can be useful when a filter needs regular replacement or when keeping a spare prevents a cleaning interruption. This roundup includes four-packs for several Dolphin and Hayward options, as well as two-packs for Polaris and Aiper models. Pack count alone does not reveal how long each filter will last; cleaning frequency, debris load, and care all affect service life. Check whether the quantity refers to complete filters, panels, inserts, or another component, since those formats are not equivalent. A smaller pack may make more sense if you are confirming fit for the first time. Avoid stocking up until you know the replacement matches your cleaner.
Account for cleaning and drying between uses
Maintenance needs can differ even when two replacements fit similar cleaners. Bags, cartridges, baskets, panels, and sponges have different shapes and may take different effort to rinse thoroughly. Before buying, consider whether the filter opens easily, whether debris can be removed without damaging the media, and how quickly it can dry before storage. Keeping a second compatible filter can let one dry while the other is in use, but that only helps if the replacement is a complete, matching part. Follow the filter maker’s care directions rather than using aggressive cleaning methods that could damage the material. Easy upkeep can matter more over time than a small difference in stated filtration fineness.
Do not assume finer filtration is always better
Fine filtration is appealing when cloudy-looking water or small particles are a recurring problem, but it can create a maintenance tradeoff. As debris builds up, a fine filter may restrict water flow sooner than a more open option. That can mean stopping to rinse more often, especially during heavy debris periods. Check whether your cleaner’s manual supports the filter type and whether the replacement is intended for routine use or a particular cleanup need. If you switch to a finer option, watch how quickly it loads rather than assuming it will reduce total cleaning work. Fit and usable cleaning intervals matter alongside particle-size claims.
Treat compatibility claims as a checklist, not a promise
Replacement listings can name several cleaner models, but buyers should still compare the product with the original part. Confirm the model number, number of pieces, filter dimensions if listed, and the attachment or locking method. Pay close attention to differences within a cleaner family, where similar names can refer to different filter assemblies. If the old part is damaged or missing, use the manual or the cleaner manufacturer’s parts diagram to identify the correct form. Do not substitute a basket for a cartridge or a bag for a robotic filter just because the brand matches. A few minutes of verification can prevent a filter that cannot be installed or sealed properly.
Frequently Asked Questions
How do I know whether a replacement filter will fit my pool cleaner?
Start with the cleaner’s exact model number, then compare it with the models named for the replacement. Check the filter’s shape and how it attaches, not just the brand name. A bag, cartridge, basket, panel, and sponge are different parts even when they serve the same broad purpose. If you cannot find the model on the cleaner, consult its manual or parts diagram. When the listing leaves your exact model unclear, confirm compatibility before ordering.
Should I choose a 3µm filter for finer pool debris?
A 3µm filter may suit owners of the named Aiper Scuba models who are targeting very small particles. Finer filtration is not automatically the best everyday choice, because fine media can load quickly and require more frequent rinsing. Check that your cleaner supports the filter and consider how much fine dust your pool collects. If larger debris is your main concern, a finer rating may add upkeep without helping with your primary problem. Treat the stated rating as one factor, not a guarantee of overall cleaning performance.
Is a multi-pack a better choice than buying one replacement filter?
A multi-pack can be useful if you replace filters regularly or want a spare ready while another filter dries. The roundup includes four-packs for several Dolphin and Hayward options, alongside two-packs for Polaris and Aiper cleaners. First confirm that every piece in the pack is the complete replacement part you need, not a set of inserts or panels with a different function. If you are unsure about fit, ordering a smaller quantity can limit the risk of ending up with unusable spares. Pack size is most useful when compatibility and replacement frequency are already clear.
Can I use a robotic cleaner filter in a Polaris pool cleaner?
No, do not treat these formats as interchangeable. The Polaris options in this roundup are replacement bags for named Polaris models, while the robotic cleaner options include cartridges, baskets, panels, and other filter media. The cleaners use different assemblies, so the filter needs to match the cleaner’s design and attachment points. Check the model-specific compatibility information before buying. A filter from the same general product category will not fit just because it captures pool debris.
When should I replace a filter instead of rinsing it?
Rinse a filter according to its care instructions when debris is visible or cleaning performance drops. Replacement becomes more likely when the media is torn, the frame or attachment points are damaged, or rinsing no longer clears the buildup. A filter that cannot seat securely may also let debris bypass the media. How often this happens depends on debris levels and cleaning frequency, so a fixed replacement schedule may not suit every pool. Keeping a compatible spare can help you avoid downtime while you inspect or clean the used filter.
Conclusion
For the best overall fit in this roundup, I’d start with the Ulticor Ultra Fine Filter Basket for Dolphin if your robotic cleaner is compatible and you prefer a basket format. For value, the four-pack Spring Filter Cartridges make more sense for owners of the named Dolphin models who want multiple replacements on hand. Buyers seeking a more specialized fine-filter option can look at the Aiper 3µm inserts for the exact Scuba model listed, while the Hayward four-pack suits owners of compatible Sharkvac cleaners. For beginners, I recommend choosing the replacement that most closely matches the original part and explicitly names the cleaner model, rather than starting with the finest filtration claim. Polaris owners should stay with the model-specific bag options, and WYBOT A1 owners should choose the sponge set made for that cleaner. Verify the exact model and filter format first; that is the clearest way to narrow these 13 choices.
