The key detail in a dolphin nautilus cc pro ultra fine filter search is the part number, not simply the words “Dolphin filter.” The Nautilus CC Pro uses an S2-style top-load basket, and Maytronics directly lists ultra-fine panel set 9991467-R4 as a compatible accessory for the current Nautilus CC Pro.
That creates a clear baseline for comparing replacement panels. The genuine Maytronics pack has direct manufacturer confirmation for the CC Pro. The three aftermarket sets in this guide all claim to replace 9991467-R4 and list many of the same S2-family cleaners, but their exact Amazon compatibility lists do not currently name Nautilus CC Pro. For those products, the part-number cross-reference is relevant, but it is not identical to a direct model-specific fit statement.
The other buying decision is filtration type. Ultra-fine pleated panels are useful when the pool cleaner is dealing with fine dust, pollen, silt-like dirt and small particles that are harder for coarser screens to retain. They also require more frequent rinsing because finer media can restrict water flow sooner as debris builds in the pleats.

What to Look for When Buying a Dolphin Nautilus CC Pro Ultra Fine Filter
Match the Exact Part Number First
For the Nautilus CC Pro, 9991467-R4 is the most useful reference point. Maytronics identifies that part as its S2 Ultra-Fine Filter Panels set and lists it directly as an accessory on the current Nautilus CC Pro product page. This is stronger evidence than assuming compatibility because two filters look alike.
Dolphin uses several similar-looking filter-panel families. For example, the Nautilus CC uses a different ultra-fine panel part number in Maytronics’ current catalog. Do not move a part number from one Dolphin model to another just because both cleaners use top-load baskets.
Understand Direct Compatibility vs Part-Number Replacement Claims
The genuine 9991467-R4 set is directly connected to Nautilus CC Pro by Maytronics. The Henkgo, Zymurgoes and CLLOMAGY listings state that they replace 9991467-R4, but their model lists focus on S200, Active, Proteus, Explorer, Triton, Prowler and M600-family cleaners.
That difference does not prove the aftermarket filters will not fit a CC Pro. It means the evidence is less direct. A careful buyer should confirm the seller’s current compatibility statement or compare the replacement frames with the existing 9991467-R4 panels before discarding the originals.
Choose Fine Media for the Debris You Actually Have
Ultra-fine pleated media makes the most sense when the robot is expected to capture small suspended or settled particles. Fine dust from landscaping, pollen, very small debris and silt-like material can be more difficult for coarse screen filters to hold.
Coarser filters have their own advantage: they can maintain flow longer when the pool has a heavy load of leaves or larger debris. Some owners therefore keep both filtration types and use the finer panels after the major debris has been removed.
Inspect the Existing Basket Before Buying Panels
A four-panel kit assumes that the reusable basket structure is still healthy. Check the basket frame, panel channels, lid, latch points and any seals or edges that locate the filters. A cracked basket can allow bypass even when new filter panels are installed.
If the basket itself is damaged, buying four new panels may not solve poor filtration. The problem has to be repaired at the part that no longer seals or holds the panels correctly.
Numbered Panel Positions Matter
Several listings in this comparison describe numbered panels that correspond to basket positions. Respect those numbers. Filter frames can appear nearly symmetrical while still having small geometry differences at tabs, corners or locating edges.
Forcing a panel into the wrong slot can distort the frame and create a gap. The goal is a panel that seats naturally and closes the filtration path around its entire perimeter.
Plan for Routine Rinsing
Ultra-fine filtration has more surface area and smaller passages than a coarse screen. That is useful for fine debris but it also means dirt can accumulate deep in the pleats. A basket that looks only moderately dirty can still have restricted flow if dust is embedded between folds.
Rinse the panels after dirty cycles, using a broad water spray rather than a concentrated high-pressure jet at close range. Inspect the pleats while rinsing so damaged seams or separated material can be identified before the next cleaning cycle.
Dolphin Genuine Replacement Part — Ultra-Fine Filter Panels (4PK) — 9991467-R4
The genuine Maytronics 9991467-R4 set is the most straightforward option for a Dolphin Nautilus CC Pro because Maytronics directly lists this part number as the Ultra-Fine Debris Filter Panels accessory on the current Nautilus CC Pro product page. That direct manufacturer connection matters more than a broad marketplace compatibility claim.
The Amazon listing contains four ultra-fine panels and identifies them as Maytronics Certified Genuine Parts. Its compatibility list covers a large group of S2-platform cleaners such as the S200, S300/S300i, Active 20/30-series, Proteus DX4/DX5i, Triton PS, Explorer E30/E50/E70 and M600. The Amazon bullet list does not currently name Nautilus CC Pro, but Maytronics’ own CC Pro page does.
Design and Build
This is a panel set rather than a complete filter basket. The Nautilus CC Pro uses a top-load basket that accepts removable filter panels. Replacing only the panels allows the basket frame to remain in service when its structure and latches are still sound.
Maytronics categorizes 9991467-R4 as an S2 ultra-fine four-panel pack. The official part page gives package dimensions of 430 × 60 × 250 mm and a gross package weight of 0.3 kg. Those are package figures, not individual panel dimensions, so they should not be used to judge basket fit by measurement alone.
Important Specifications
The main specification is the exact part number: 9991467-R4. For replacement filters, part-number matching is more useful than comparing generic dimensions because Dolphin baskets use specific panel frames and locating points. Maytronics also assigns the set EAN 810071220944.
Maytronics recommends replacing the filter after approximately 200 hours of use. That is a maintenance guideline rather than a guarantee that every set will stop working at the same hour count. Water chemistry, debris type, cleaning method and how carefully the pleats are rinsed all influence usable life.
Practical Use
Ultra-fine pleated media is intended for material that can pass more easily through coarser screens. In a pool that collects fine dust, pollen, silt-like particles or small suspended debris, the extra filtration surface can improve what the robot retains during a cleaning cycle.
The tradeoff is that finer media can load with dirt more quickly. As pleats fill, water flow through the basket can decrease. Rinsing the panels thoroughly after dirty cycles is therefore more important than simply emptying leaves from the basket.
Installation and Maintenance
Remove the basket from the cleaner and replace panels with the robot disconnected from power. The panels are shaped to fit designated positions in the basket. After installation, confirm that every panel is seated fully so water cannot bypass the media through a gap at the frame.
For routine cleaning, rinse from the cleaner side of the pleats toward the dirty side when practical so trapped debris is pushed out rather than deeper into the folds. Avoid scraping the pleated material with sharp tools. Allow stubborn dirt to loosen with water instead of forcing it out mechanically.
Important Strengths
The strongest reason to choose this set is compatibility confidence. The part number is directly supported by the manufacturer for Nautilus CC Pro, so there is no need to infer fit only from similar Dolphin models.
Genuine parts also remove uncertainty about frame geometry, panel indexing and filtration specification. That can matter for owners who prefer to keep the cleaner entirely within Maytronics replacement-part specifications.
Important Limitations
The genuine set can cost more than aftermarket replacements, and the practical value of that premium depends on how strongly you prioritize manufacturer confirmation and OEM construction.
This package replaces the four panels only. If the filter basket frame itself is cracked, warped or has damaged latches, new panels alone will not correct that structural problem.
Who Should Consider It
Choose the genuine 9991467-R4 set if your priority is direct Nautilus CC Pro compatibility confirmation and you want a Maytronics-branded replacement with the manufacturer’s maintenance guidance.
Who Should Consider Another Option
Consider an aftermarket set if you are comfortable buying by replacement part number and seller compatibility claims, especially when purchase cost is a larger priority than OEM sourcing.
Pros
- Directly listed by Maytronics as a Nautilus CC Pro accessory
- Genuine 9991467-R4 four-panel S2 set
- Manufacturer provides a clear replacement guideline
- Avoids uncertainty about third-party panel geometry
Cons
- Typically positioned above generic replacements in cost
- Panels only; does not replace a damaged basket frame
- Amazon compatibility bullets do not explicitly name Nautilus CC Pro even though Maytronics does
Henkgo 9991467-R4 Ultra-Fine Filter Panels Replacement
The Henkgo GLW-A1 is an aftermarket replacement sold against part number 9991467-R4. Its Amazon listing describes direct replacement use with the same broad S2-family cleaners named on the genuine Amazon page, including Active 20/30-series models, Explorer E30/E50/E70, Proteus DX4/DX5i, S200/S300/S300i/S400, Triton PS and M600.
The important limitation for a Nautilus CC Pro owner is wording: the exact Henkgo listing does not explicitly include Nautilus CC Pro in its model list. Because Maytronics confirms that the CC Pro uses genuine part 9991467-R4, the part-number match is relevant, but it is still a step below direct third-party model confirmation.
Design and Build
Amazon identifies Henkgo as the brand and GLW-A1 as the model name. The product overview lists plastic construction, white color and product dimensions of 9 × 8 × 2.1 inches for the item. Those marketplace dimensions should be treated as listing data rather than a substitute for checking the exact basket and part number.
The listing says each panel is numbered to match a position in the filter basket. Numbering can simplify replacement because the user can maintain the intended panel orientation rather than forcing similar-looking panels into the wrong position.
Important Specifications
Henkgo markets the set as a replacement for 9991467-R4 and lists the same extended compatibility family used by Maytronics for S2 ultra-fine panels. The page also describes the pleated panels as washable and reusable.
The seller recommends removing the old panels in numerical order and installing replacements in reverse order. That is an installation convenience specific to how the numbered frames are organized, not a performance specification.
Practical Use
For normal pool dust and fine debris, the intended role is the same as the genuine ultra-fine panels: provide pleated media with more fine-particle capture than coarse screens. The practical question is whether the aftermarket frame seals and pleat construction remain consistent through repeated wash cycles.
Rinse pressure matters. A strong hose jet can clean dirt quickly, but concentrated pressure at close range can also stress pleats or seams. A broad spray and patience are better than trying to blast embedded debris out from a few inches away.
Installation and Maintenance
Before discarding the original panels, compare the Henkgo frames side by side. Check tabs, edge profile and panel numbering. If any frame needs force to seat, stop and confirm orientation rather than bending the plastic to make it fit.
After the first cleaning cycle, inspect the basket for debris tracks around the panel edges. Dirt bypassing the media can indicate that a panel is not fully seated or that the frame fit differs from the original.
Important Strengths
Henkgo provides a clearly labeled 9991467-R4 replacement with a broad model list that closely mirrors Maytronics’ S2 compatibility family. The numbered panels and washable pleated construction are practical features for routine servicing.
For buyers comparing aftermarket sets, the listing also provides identifiable brand and model information instead of presenting the item as a completely unbranded replacement.
Important Limitations
The exact Amazon compatibility list does not name Nautilus CC Pro. A CC Pro owner is therefore relying on the 9991467-R4 cross-reference rather than an explicit Henkgo fitment statement for that cleaner.
Seller language such as ‘original version quality’ is marketing wording and should not be interpreted as proof that materials, filtration performance or service life are identical to Maytronics genuine panels.
Who Should Consider It
Consider Henkgo if you want an aftermarket 9991467-R4 set from an identifiable brand and are comfortable confirming CC Pro fit through the OEM part-number relationship.
Who Should Consider Another Option
Choose the genuine Maytronics pack if direct manufacturer confirmation for Nautilus CC Pro matters more than the potential savings of an aftermarket alternative.
Pros
- Clear 9991467-R4 replacement positioning
- Numbered panels simplify basket placement
- Broad S2-family compatibility list
- Washable pleated-media design
Cons
- Nautilus CC Pro is not explicitly named on the exact listing
- Performance equivalence to OEM media is not independently established
- Marketplace dimensions should not replace part-number verification
Zymurgoes 9991467-R4 Ultra-Fine Filter Cartridge Panels, 4 PCS
The Zymurgoes set is another four-piece aftermarket replacement for 9991467-R4. Its Amazon title names Proteus DX4, Active 20/30/30i/40/60, Explorer E30/E50/E70, M600, Triton PS, S300i and S200, while the bullet list expands compatibility to additional S2-family models.
As with the Henkgo option, Nautilus CC Pro is not explicitly named on the exact product page. The connection to CC Pro comes from the replacement part number: Maytronics identifies genuine 9991467-R4 as a compatible CC Pro accessory. Buyers should understand that this is a part-number inference for the aftermarket product rather than direct Zymurgoes model confirmation.
Design and Build
Amazon identifies the brand as Zymurgoes and the model name simply as Filter Panels. The page describes the panels as plastic-framed and black-and-white. It also lists a product-dimension entry that appears internally inconsistent for a filter-panel set, so those dimensions are not useful for evaluating fit and should not drive the purchase.
The more reliable design information is the four-panel format and numbered placement. The seller says each panel corresponds with a designated basket position, which is consistent with the S2-style replacement arrangement.
Important Specifications
Zymurgoes states that the panels are intended to replace 9991467-R4 and describes them as multi-layer ultra-fine filters. The listing says they can be rinsed with a garden hose after use.
The seller also advertises a 30-day return option and a 12-month warranty. Those are seller/listing terms and can change, so they should be verified on the live Amazon page if warranty coverage is an important part of the buying decision.
Practical Use
The main buying appeal is simple: four replacement panels in the correct general S2 format without paying for a complete basket. That is useful when the existing basket is structurally sound but its pleated media is stained, clogged or physically damaged.
The page emphasizes fine-particle capture for dust, dirt and other small contaminants. In practice, very fine filtration works best when the panels are cleaned frequently enough to maintain water flow through the pleats.
Installation and Maintenance
Zymurgoes recommends removing panels from positions 1 through 4 and reinstalling from 4 back to 1. The important principle is to respect the panel numbering and ensure that every edge seats correctly in the basket.
After rinsing, inspect for pleat separation, cracked frame corners or distorted edges. Reusing a panel that no longer seals against the basket can allow water to take the easier path around the media.
Important Strengths
The listing clearly identifies a four-piece 9991467-R4 replacement and provides a detailed S2 compatibility list. It also gives straightforward maintenance and panel-position guidance.
The advertised seller warranty may appeal to buyers who want some stated support beyond Amazon’s normal return process, though current terms should be checked before relying on them.
Important Limitations
Nautilus CC Pro is not stated in the compatibility list, so CC Pro fit is not directly confirmed by the aftermarket brand on this page.
One dimension entry on the Amazon product data is not plausible for this type of filter set. Omitting that figure is safer than using questionable marketplace metadata to compare products.
Who Should Consider It
Consider Zymurgoes if you want a four-panel 9991467-R4 aftermarket set and value a listing that includes numbered installation guidance and an advertised warranty period.
Who Should Consider Another Option
Choose genuine Maytronics if you want the replacement recommendation and Nautilus CC Pro compatibility to come from the cleaner manufacturer rather than from part-number matching.
Pros
- Four-panel replacement set for part 9991467-R4
- Detailed S2-family compatibility list
- Numbered installation guidance
- Seller advertises a 12-month warranty
Cons
- Nautilus CC Pro is not explicitly listed
- Some marketplace dimension data is unreliable
- Ultra-fine performance equivalence to OEM is not independently verified
CLLOMAGY 9991467-R4 Ultra-Fine Filter Panels
CLLOMAGY’s FP-001 is an aftermarket 9991467-R4 replacement set. The exact Amazon title highlights S200, Proteus DX4, Active 20, Active 30, M600 and S300i, and the bullet list adds Active 30i/40/60, Explorer E30/E50, Proteus DX5i, Prowler models, S300/S400, Triton PS and several related cleaners.
Again, Nautilus CC Pro is not named on the third-party listing. The reason this product is relevant to a CC Pro search is the shared 9991467-R4 replacement number, which Maytronics independently confirms for the CC Pro. That is useful evidence, but it is not the same as an explicit CLLOMAGY CC Pro statement.
Design and Build
Amazon lists CLLOMAGY as the manufacturer and FP-001 as the item model number. The product details give overall item dimensions of 9 × 8 × 2.5 inches and an item weight of 1.15 pounds.
The listing describes a pleated filter system and numbered panel positions. The frame-and-pleat format is intended to slide into the existing S2 basket rather than replace the entire basket assembly.
Important Specifications
CLLOMAGY positions the item as a direct replacement for part 9991467-R4. Its model list is similar to the other aftermarket pages but slightly shorter in some places, with Explorer E70 not included in the feature-bullet list currently visible on the page.
The page emphasizes rinse-and-reuse maintenance with a garden hose. It does not provide a manufacturer-backed replacement-hour interval comparable with Maytronics’ 200-hour guidance for the genuine part.
Practical Use
The CLLOMAGY set is most relevant when an owner wants another third-party choice with clearly stated model number and basic product dimensions. Those details can make it easier to distinguish the item from visually similar generic filters in an order history.
As with any pleated aftermarket set, fit should be checked before the old panels are discarded. A panel that looks nearly identical can still differ at tabs or edge seals, and small geometry differences can affect bypass around the media.
Installation and Maintenance
Follow the numbered panel arrangement and seat each panel without forcing it. Once all four are installed, run a short cleaning cycle and inspect the basket afterward. Consistent dirt loading across panels is a better sign than one panel remaining clean while another becomes heavily loaded.
Clean the pleats after debris-heavy cycles and inspect the frames for cracking. Repeatedly flexing the plastic during removal can shorten frame life, so use the intended release points rather than pulling on the pleated media.
Important Strengths
CLLOMAGY provides identifiable item details—brand, model number, dimensions and a specific 9991467-R4 replacement claim. That makes it easier to compare with other aftermarket sets than a listing that supplies only a generic title.
The compatibility list also covers the main S2 cleaner families that use the genuine 9991467-R4 panels.
Important Limitations
There is no direct Nautilus CC Pro statement on the exact Amazon listing. Buyers must rely on the matching OEM part number and their own confirmation of basket compatibility.
The listing does not publish an equivalent to Maytronics’ 200-hour replacement recommendation, so service life should be judged by filter condition and cleaning performance rather than an assumed OEM interval.
Who Should Consider It
Consider CLLOMAGY if you want an aftermarket 9991467-R4 option with clear item identification and broad S2-family compatibility claims.
Who Should Consider Another Option
Choose the genuine part if you want direct Maytronics confirmation for Nautilus CC Pro and a manufacturer-specified maintenance reference.
Pros
- Clear 9991467-R4 replacement claim
- Identifiable FP-001 model number and item dimensions
- Numbered-panel installation approach
- Broad compatibility with common S2-family cleaners
Cons
- Nautilus CC Pro is not explicitly named on the listing
- No manufacturer-backed replacement-hour guidance
- Equivalent filtration performance to OEM is not independently established
Detailed Buying Guide
Why the Genuine Part Has the Clearest CC Pro Fitment
The genuine Maytronics set has one advantage that the aftermarket products cannot reproduce simply by printing 9991467-R4 in a title: the cleaner manufacturer itself links the part to Nautilus CC Pro. That removes a compatibility step for the buyer.
Maytronics’ general 9991467-R4 part page lists a long range of compatible S2 robots but does not include every regional product name. The Nautilus CC Pro product page resolves that uncertainty by presenting 9991467-R4 as a compatible ultra-fine accessory for the CC Pro itself.
Why the Aftermarket Listings Are Still Relevant
All three third-party products are marketed as replacements for 9991467-R4, and all three list many cleaners that also appear on Maytronics’ official compatibility information for that genuine part. That makes the part-number relationship meaningful rather than random.
The remaining uncertainty is model naming. A replacement seller may build one compatibility list from a subset of U.S. models and omit another cleaner that uses the same basket platform. The safe approach is to treat the aftermarket product as a 9991467-R4 substitute and independently confirm that your exact cleaner currently uses that part number.
Fine Filters vs Standard Fine Panels
Dolphin terminology can be confusing because “fine” and “ultra-fine” are not interchangeable labels. The Nautilus CC Pro can use filter panels of different filtration grades depending on the accessory configuration. The ultra-fine 9991467-R4 set is the option aimed at smaller particulate capture.
For routine heavy leaf pickup, ultra-fine media may not be necessary for every cycle. A useful strategy is to remove large debris first with the standard filtration setup, then use ultra-fine panels when the goal shifts to smaller dirt and water clarity.
What a Four-Panel Set Does Not Replace
The four panels do not replace the entire top-load filter basket. They also do not repair the basket handle, latches or structural grid. If a basket panel channel is warped, a perfectly good new filter panel may still sit incorrectly.
This distinction matters because “filter replacement” can refer to either the media panels or the full basket assembly. Check which part is actually damaged before ordering.
When to Replace Instead of Keep Cleaning
A pleated panel does not need replacement simply because it looks discolored. Cosmetic staining can remain after the media is functionally clean. Replacement makes more sense when pleats are torn, frames are cracked, media has separated from the frame, or normal rinsing no longer restores acceptable flow.
Maytronics’ roughly 200-hour recommendation provides a useful service reference for the genuine panel set. Use it together with physical condition rather than treating the hour count as an automatic failure point.
How Water Flow Affects Robot Cleaning
The filter basket sits in the robot’s internal water path. Water has to move through the media for debris to be retained. If ultra-fine panels become heavily loaded, the increased resistance can reduce the volume of water passing through the filtration system.
That is why a clean filter can affect more than visual water clarity. Maintaining open pleats helps the cleaner operate with the airflow—or more accurately water-flow—path its suction system expects.
Hose Rinsing Technique
Remove loose debris first, then rinse across the pleats from multiple angles. A broad spray helps lift material out of the folds. Very high localized pressure can deform pleats or stress glued/sealed edges, so more pressure is not always better.
After rinsing, hold the panel toward light and inspect the frame and pleat junction. A small separation can allow bypass and can grow with repeated removal and washing.
Storage Between Uses
If panels are removed for seasonal storage, let them dry before sealing them in a closed container. Store them flat or in a way that does not bend the frame. Avoid placing heavy pool equipment on top of dry filter panels.
Keeping the old genuine panels until an aftermarket set has been installed and checked is also practical. The originals provide a direct geometry reference if a replacement frame looks slightly different.
OEM vs Aftermarket: What the Price Difference Represents
The genuine set is not automatically the right purchase for every owner, and an aftermarket set is not automatically a poor purchase. The difference is mainly in verification and sourcing. OEM gives direct manufacturer fitment, part identification and maintenance guidance.
Aftermarket products compete by offering a replacement around the same part number, sometimes with lower purchase cost or different seller warranty terms. The buyer accepts more responsibility for confirming exact fit and judging long-term media quality.
Direct Product Comparisons
Dolphin Genuine 9991467-R4 vs Henkgo GLW-A1
The genuine Dolphin set has direct Nautilus CC Pro support from Maytronics. Henkgo GLW-A1 is sold as a 9991467-R4 replacement and lists many of the same S2 cleaners, but it does not explicitly name the CC Pro.
Henkgo does provide clear brand, model and numbered-panel information. The decision is therefore between stronger compatibility certainty from Maytronics and the aftermarket value proposition of a part-number substitute.
Dolphin Genuine 9991467-R4 vs Zymurgoes
Both are four-panel sets positioned around the same part number. Maytronics supplies the official compatibility connection and a replacement recommendation of roughly 200 hours. Zymurgoes adds seller-advertised return and warranty language but does not provide direct CC Pro model confirmation.
If warranty wording is important, check the current Amazon terms immediately before purchase because third-party seller policies can change. The genuine set’s stronger distinction is not a seller warranty claim; it is the direct relationship to the cleaner manufacturer.
Dolphin Genuine 9991467-R4 vs CLLOMAGY FP-001
CLLOMAGY provides a clearly identified FP-001 model and publishes item dimensions, which can be useful for order identification. The genuine pack provides cleaner compatibility confidence that CLLOMAGY’s page does not match for Nautilus CC Pro.
For a buyer who already confirmed that the basket uses 9991467-R4, CLLOMAGY becomes a plausible aftermarket candidate. For a buyer who is unsure which part the cleaner needs, the genuine Maytronics path is simpler.
Henkgo vs Zymurgoes
Both listings use a broad S2 compatibility list and numbered-panel installation approach. Henkgo identifies its replacement as GLW-A1 and supplies an item-dimension entry. Zymurgoes emphasizes four-piece packaging, hose-rinse maintenance and an advertised warranty period.
Neither exact page names Nautilus CC Pro, so neither removes the same compatibility question. Fit should be judged by the 9991467-R4 cross-reference rather than by which listing contains more model names.
Zymurgoes vs CLLOMAGY
Zymurgoes lists a wider group of models in its current bullet content and advertises a 12-month warranty. CLLOMAGY provides cleaner product-detail metadata with model FP-001 and dimensions of 9 × 8 × 2.5 inches.
Those differences are secondary to panel fit and filtration quality. If both claim the same OEM replacement number, the most important checks are frame seating, edge sealing and how well the media survives repeated cleaning.
Henkgo vs CLLOMAGY
Henkgo and CLLOMAGY both give identifiable model information and publish 9991467-R4 replacement claims. Henkgo’s current compatibility list includes Explorer E70, while CLLOMAGY’s visible bullet list stops at Explorer E50.
That difference shows why model-list length should not be treated as proof of better engineering. Listings can omit names even when products target the same replacement family. The OEM part number remains the stronger reference.
Common Buying Mistakes
Buying a Similar-Looking Dolphin Filter With a Different Part Number
Dolphin uses several panel designs that can look similar in photos. Do not assume that an ultra-fine four-panel set for another Dolphin model is interchangeable with 9991467-R4. Confirm the cleaner’s actual part family first.
Assuming Every 9991467-R4 Aftermarket Listing Explicitly Supports Nautilus CC Pro
The three third-party listings in this comparison do not currently name Nautilus CC Pro in their visible compatibility bullets. Their relevance comes from the replacement part number. That is a meaningful but different form of compatibility evidence.
Replacing Panels When the Basket Is Damaged
New pleated media cannot fix a cracked basket frame, broken latch or distorted panel channel. Inspect the basket before ordering panel-only replacements.
Using Ultra-Fine Panels Without Cleaning Them Often Enough
Fine media captures smaller material and can load faster. If the robot is used in a very dirty pool and the panels are not rinsed, reduced flow can limit effective filtration.
Cleaning With Excessive Water Pressure
A garden hose is appropriate for rinsing, but a narrow high-pressure stream can stress pleats and panel seams. Use enough water to flush debris without treating the media like a pressure-washer surface.
Throwing Away the Old Panels Before Confirming Aftermarket Fit
Keep the original 9991467-R4 panels until replacement installation is complete. They provide a useful geometry reference and a fallback if an aftermarket frame does not seat correctly.
Relying on Questionable Marketplace Dimensions
Marketplace product data is not always internally consistent. If a dimension entry conflicts with the physical type of product, omit it from the decision and use the part number, brand documentation and actual frame geometry instead.
Frequently Asked Questions
What ultra-fine filter part fits the Dolphin Nautilus CC Pro?
Maytronics currently lists Ultra-Fine Debris Filter Panels part 9991467-R4 as a compatible accessory for the Nautilus CC Pro.
How many panels are in 9991467-R4?
The genuine Maytronics package contains four ultra-fine filter panels. The three aftermarket products compared here are also sold as four-panel replacement sets.
Does the genuine Amazon listing name Nautilus CC Pro?
The genuine Amazon compatibility bullets currently list many S2-family cleaners but do not name Nautilus CC Pro. Maytronics’ own Nautilus CC Pro page directly lists 9991467-R4, which provides the clearer model-specific confirmation.
Do the Henkgo, Zymurgoes and CLLOMAGY listings explicitly say Nautilus CC Pro?
Their current visible compatibility lists do not name Nautilus CC Pro. They are relevant because they are marketed as replacements for 9991467-R4, the part number Maytronics confirms for CC Pro.
What is the difference between fine and ultra-fine Dolphin filters?
Ultra-fine pleated media is intended to retain smaller particulate than coarser filtration. It can also load with dirt faster, so it generally benefits from more frequent rinsing.
How often should genuine 9991467-R4 panels be replaced?
Maytronics recommends replacing the genuine filter after roughly 200 hours of use. Physical condition and cleaning performance should also be considered.
Can I wash ultra-fine filter panels with a garden hose?
Yes. The products in this comparison are designed for rinse-and-reuse maintenance. Use a broad spray and avoid damaging the pleats with excessive concentrated pressure.
Do I need to replace the entire filter basket?
Not if the basket frame and latches are still in good condition. 9991467-R4 is a panel set. Replace the basket only when the basket itself is damaged or no longer holds the panels correctly.
Why are the panels numbered?
Numbering helps place each panel in the intended position in the basket. Correct seating reduces the chance of gaps that can allow dirty water to bypass the media.
Can ultra-fine filters help with pool dust and pollen?
That is one of the main reasons to use pleated ultra-fine media. Smaller particles such as dust, pollen and silt-like debris are the type of material these panels are intended to retain more effectively than coarse screens.
Should I use ultra-fine filters for a pool full of leaves?
They can collect leaves, but a coarse filter may maintain flow longer during heavy large-debris cleanup. Ultra-fine panels are most useful after major debris is removed and smaller particulate becomes the priority.
Is OEM always better than aftermarket?
OEM provides the strongest compatibility certainty and direct manufacturer guidance. Aftermarket filters can be practical substitutes when the exact part number is confirmed, but fit, media quality and service life depend on the specific product.
How to Verify a 9991467-R4 Replacement Before Regular Use
Compare the Replacement With the Original Panels
Before installing an aftermarket set, place each new panel beside the corresponding original panel. Compare the outer frame, locating tabs, corner shape and the depth of the sealing edges. A replacement does not need identical surface texture to function, but the structural points that locate the panel in the basket should align closely.
This comparison is especially useful for Nautilus CC Pro owners because the third-party Amazon listings in this guide are sold against 9991467-R4 without explicitly naming the CC Pro. Keeping the old OEM panels until the new set has completed a successful cycle gives you a direct physical reference if something appears unusual.
Check for Edge Gaps After Installation
Once all four panels are fitted, look around every edge before returning the basket to the cleaner. A visible gap can create a bypass path where water takes the easier route around the filter instead of through the pleated media. Small fit differences matter more with ultra-fine filtration because the purpose of the media is to retain particles that would otherwise pass through a coarser system.
Do not solve a poor fit by bending the frame aggressively or trimming plastic. If a panel does not seat naturally in the numbered position, verify orientation and part number first. Modifying the frame can make a return difficult and may create a weaker seal.
Run a Short Initial Cleaning Cycle
After installing a new set, the first cycle can be used as a fit check rather than waiting until the pool is heavily dirty. Run the cleaner in normal conditions, then remove the basket and inspect how debris has collected across the four panels.
Reasonably similar loading across the media is a useful sign that water is moving through the intended filtration area. If one panel remains unusually clean while dirt collects behind an edge or inside the basket where it should not, reseat the panel and check the frame for distortion.
Watch Cleaning Performance as the Panels Load
Ultra-fine panels can capture smaller debris, but that advantage also means they can become restrictive faster in a very dusty pool. If the cleaner begins a cycle with clean panels and performance changes noticeably after a short period in dirty water, inspect the pleats before assuming the robot has a motor or navigation problem.
For pools with mixed debris, a two-stage approach can be practical: remove leaves and larger material with coarser filtration first, then install ultra-fine panels for the remaining dust and fine particulate. This reduces the amount of large debris occupying pleated-media surface area.
Keep Panel Cleaning Consistent
Rinsing technique can affect how evenly the four panels age. Clean all panels during the same maintenance session instead of repeatedly rinsing only the dirtiest-looking one. Fine particles can remain deep between pleats even when the surface appears relatively clean.
Inspect panel frames at the same time. Cracks at tabs, corners or the pleat-to-frame junction can gradually become bypass points. Replacing one visibly damaged panel may be possible if an exact matching panel is available, but a complete four-panel refresh keeps age and media condition consistent across the basket.
Use the Part Number as the Long-Term Reference
Product titles and seller compatibility lists can change over time, but the OEM part number is the more stable reference. Record 9991467-R4 with your Nautilus CC Pro maintenance notes so future replacements can be checked against the same specification rather than chosen from a generic search for “Dolphin ultra-fine filter.”
If Maytronics later updates the cleaner’s accessory list or supersedes the part number, use the manufacturer’s current information as the deciding reference. That approach is safer than assuming an older marketplace title remains accurate indefinitely.
Final Buying Considerations
For a dolphin nautilus cc pro ultra fine filter, part number 9991467-R4 is the central fact. Maytronics directly links that genuine S2 four-panel pack to Nautilus CC Pro, making it the clearest option when compatibility certainty is the priority.
Henkgo, Zymurgoes and CLLOMAGY all target the same 9991467-R4 replacement family and list many of the same Dolphin S2 cleaners. Their limitation is not that they are automatically incompatible; it is that their exact Amazon pages do not explicitly add Nautilus CC Pro to the model list. Confirm the current seller fitment if you choose one of those alternatives.
Whichever set you install, inspect the basket before replacing panels, follow the numbered positions, rinse pleats regularly and replace filters that develop frame cracks, torn media or persistent flow restriction. Ultra-fine filtration is most useful when the media remains clean enough for the robot’s water path to work as intended.
