The Henkgo ultra-fine filter panels are a direct replacement for the OEM part 9991467-R4, designed specifically for Dolphin robotic pool cleaners. These pleated cartridge filters are ideal for pool owners who want to maintain sparkling water without frequent skimming. They fit a wide range of models including the S200, Active 20, Proteus DX4, M600, and many more, making them a versatile upgrade for most Dolphin owners.
Standout features include the ultra-fine pleated material that captures sand, gravel, leaves, and even microscopic debris. In real-world use, these filters dramatically improve water clarity compared to standard mesh filters. The numbered panels (1-4) simplify installation: remove in order and replace in reverse, so even first-time users can swap them in minutes. The filters are also washable with a garden hose, retaining their shape and effectiveness after repeated cleanings.
Build quality is reassuringly sturdy. The pleated material holds up well under water pressure and regular cleaning. Each panel measures 9 x 8 x 2.1 inches and weighs just over a pound, making them lightweight yet durable. The white color blends inconspicuously into most pool cleaner baskets. Compatibility is extensive, covering over 25 Dolphin and Maytronics models, which adds significant value for households with multiple cleaners or future upgrades.
One potential drawback is that the ultra-fine mesh may clog faster than coarser filters, especially in heavily debris-laden pools. This means more frequent cleaning sessions, but the ease of rinsing offsets this inconvenience. Additionally, while compatibility is broad, it is not universal, so buyers should verify their specific model before ordering. The initial fit on some cleaner baskets might feel snug, but this ensures a secure seal.
Overall, the Henkgo ultra-fine filter panels offer an excellent balance of performance, durability, and affordability. They deliver professional-grade filtration at a fraction of the OEM cost. For Dolphin pool cleaner owners seeking clearer water and less maintenance, these filters are a smart investment. The simple installation and reusable design make them a practical choice for any pool season.
Buying Guide
Mesh Density and Micron Rating
Ultra fine filters are defined by how small a particle they can trap. The lower the micron number, the finer the filtration. For most pool owners, a filter in the 100 to 200 micron range captures sand, silt, and algae spores effectively. The OUCAXIA Y10 replacement filter (180 microns) and the CHENGLAI ultra-fine mesh bag both excel at this. If your pool sees heavy debris like pollen or plaster dust, go with a sub-150 micron filter for the best clarity.
Keep in mind that ultra fine mesh can slow water flow slightly, but the trade-off is a cleaner pool. Most of the filters we recommend balance fine filtration with good flow rates. For a deep dive into cartridge options, see our guide to washable pool cleaner filter cartridges.
Compatibility with Your Pool Cleaner
Not all filters are universal. A skimmer sock from Coopache fits any skimmer basket, but replacement panels for robotic cleaners must match the exact model. The Henkgo 9991467-R4 panels fit Dolphin S200, Active 30, and others. The Kerneed M400 set works with Dolphin Nautilus CC Plus and similar units. Always check the compatibility list before buying. Some brands like POOL BLASTER sell genuine replacement bags tailored to their vacuums, ensuring a perfect seal.
For robotic cleaners, look for numbered panels that snap into place. The fishing port filter basket is engineered specifically for the Aiper Scuba S1, while the OUCAXIA replacement is a direct fit for the Y10. Using the wrong filter can cause leaks or poor suction. If you own a robot, read our top picks for washable robot replacement filters.
Reusability and Durability
A reusable filter must withstand repeated washing. Nylon mesh with double stitching, like the Alocs replacement bag, holds up to weekly rinsing without tearing. The U.S. Pool Supply skimmer socks are durable enough to be reused several times before replacement. Premium materials, such as the reinforced seams on the CHENGLAI bags, resist fraying even when stuffed with heavy wet debris.
Ease of cleaning matters too. Most filters can be hosed off, but some like the Kerneed cartridges benefit from an occasional soak. Filters that are quick to remove and reinstall encourage regular maintenance, which prolongs the life of both the filter and your pool cleaner. For more durable options, see our best robotic pool cleaner replacement filter reusable list.
Fit and Seal Quality
A poor fit allows unfiltered water to bypass the filter, letting debris recirculate. Genuine replacements like the POOL BLASTER bag create a watertight seal. For universal bags, adjustable drawstrings with locking buckles (as on the SIFFOI 4-pack) ensure a secure attachment. Rigid frames, like those on the Henkgo and Kerneed panels, click into place without gaps.
When buying third-party filters, choose brands that specify exact model compatibility. The Coopache skimmer socks fit any basket shape because of their stretchy elastic. Testing the seal before a full cleaning session saves you frustration. For more on basket-style filters, check our best pool robot filter basket washable article.
Final Thoughts
After reviewing dozens of options, we believe the POOL BLASTER Genuine Replacement Xtreme Multilayer is the best choice for owners of compatible Water Tech vacuums, thanks to its triple-layer design and perfect factory seal. For those who want an affordable way to protect their skimmer and pump, the U.S. Pool Supply Pool Skimmer Filter Socks in the 50-pack offer outstanding value and reliable fine filtration. Both are reusable, washable, and built to last, giving you crystal-clear water without constant filter changes.
Frequently Asked Questions
How often should you replace an ultra fine pool cleaner filter?
Most ultra fine filters are washable and can be reused many times. Replace them when you notice tears, stretched elastic, or a permanent clog that rinsing cannot fix. Depending on usage, a skimmer sock may last 2 to 8 weeks, while a heavy-duty bag or robotic panel can last a whole season. For maintenance tips, see our guide to washable replacements for robotic cleaners.
Can these filters be used in saltwater pools?
Yes, most ultra fine reusable filters are made from nylon or polyester mesh that resists salt corrosion. Rinse them with fresh water after each use to remove salt residue and extend their life. The POOL BLASTER and U.S. Pool Supply products perform well in saltwater environments.
What micron rating is best for fine sand and silt?
For capturing fine sand and silt, look for filters rated between 100 and 200 microns. The OUCAXIA Y10 replacement filter (180 microns) and the CHENGLAI ultra-fine mesh bag (approx. 150 microns) both do an excellent job. Lower micron ratings catch even smaller particles but may require more frequent cleaning.
How do I clean a reusable pool filter properly?
Remove the filter and spray it with a garden hose from the inside out to dislodge trapped dirt. For stubborn buildup, soak it in a mild detergent solution for 15 minutes, then rinse thoroughly. Avoid using bleach or harsh chemicals as they can weaken the mesh. Allow the filter to air dry completely before reinstalling.
