Pros
- Ultra-fine filtration traps even tiny particles for superior water clarity.
- Easy numbered installation system reduces setup time and guesswork.
- Washable and reusable design offers long-term value and eco-friendliness.
- Broad compatibility with many Dolphin and Maytronics robotic pool cleaner models.
- Sturdy build quality withstands regular use and cleaning without tearing.
Cons
- May require more frequent cleaning than standard filters due to ultra-fine mesh trapping more debris.
- Not compatible with all Dolphin models; double-check compatibility before purchase.
- Some users may find the initial fit slightly tight on certain cleaner baskets.
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
Compatibility with Your Dolphin Model
Not every filter fits every Dolphin model. The S200 uses the 9991467-R4 part number, but many filters also work with Active 20, Active 30, Explorer E30, Proteus DX4, and other robots. Always check the product description to confirm your model is listed. Filters labeled for S200, S300, S300i, and S400 generally share the same basket design. If you own a different model like the E20, see our Dolphin E20 ultra fine filter guide.
Filtration Efficiency and Mesh Type
Ultra fine filters capture tiny particles down to around 0.5 mm, including sand, dust, and algae spores. Pleated fabric filters offer a large surface area for trapping debris, while mesh surface filters (like the 9991463-R4) are easier to rinse clean. Consider your pool’s typical debris: fine sand demands mesh, while leaves and twigs work fine with pleated panels.
Build Quality and Durability
Look for reinforced stitching, a sturdy ABS plastic frame, and thick material that resists tearing. Filters that last 2 3 years with proper care save you money over time. Rinsing every 4 6 weeks with a garden hose keeps them performing well. Avoid filters that feel flimsy or have thin fabric, as they may deform quickly under water pressure.
Ease of Installation and Cleaning
Most filters are numbered 1 4 for correct placement in the basket. Simply remove old panels in order and install new ones in reverse order. Cleaning is straightforward: pop out the panels and spray with a garden hose. Some filters require more effort to clean than others, so check reviews for user feedback on this aspect.
