Detailed Review

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.

Detailed Review

The Fiitzn Ultra Fine Filtration Basket is a replacement filter designed for a wide range of Dolphin robotic pool cleaners, including models like the S50, Active 15, Echo, Nautilus CC, Encore, E10, E20, Proteus DX3, Solo, and Advantage. This part (9991460-R1) is ideal for pool owners seeking an affordable, high-performance alternative to the original filter. It is especially suited for those who want to improve water clarity by trapping fine particles without sacrificing cleaning efficiency.

The standout feature of this basket is its microfiltration technology, which captures small debris while allowing larger particles to pass through. This design prevents the filter from clogging quickly, ensuring consistent suction and longer cleaning cycles. In real-world use, this means less downtime for rinsing and more effective pool maintenance, even in dirty conditions. The basket maintains strong performance over weeks of use before needing a quick rinse.

Build quality is solid thanks to the ABS plastic frame, which resists cracking and deformation under pressure. The filter layer is securely supported, reducing the risk of tearing during operation. Installation is straightforward: it fits exactly like the original part, so no modifications or adapters are needed. Rinsing every 4-6 weeks keeps it working optimally, and with proper care, the basket can last 2-3 years, offering excellent value.

One potential drawback is that in extremely dirty pools, the filter may need more frequent rinsing to maintain flow. Additionally, the package includes only one basket, so owners of larger pools might need to buy a second. Also, while compatibility is broad, it does not cover every Dolphin model, so double-checking the list is wise. These are minor trade-offs for the price and performance.

Overall, the Fiitzn Ultra Fine Filtration Basket delivers on its promise of efficient fine debris capture and durability. It is a smart upgrade or replacement for Dolphin pool cleaner owners who want to keep their water crystal clear without breaking the bank. The combination of microfiltration, sturdy construction, and broad compatibility makes it a reliable choice for routine pool care.

These SUNRRA ultra fine pleated filters are a drop-in replacement for several Maytronics Dolphin models, including the Nautilus CC Plus and M series. Their dense pleats trap finer debris than standard filters, and the 4-pack offers great long-term value for pool owners who want crystal-clear water.
Pros & Cons

Pros

  • Superior filtration from ultra fine pleated material, outperforming standard non-pleated filters.
  • Durable ABS frame withstands regular use and chemical exposure without cracking.
  • Cost-effective 4-pack reduces per-cartridge cost and frequency of replacement.
  • Easy to clean and reuse, extending the life of each filter panel.
  • Backed by a 1-year warranty for added confidence.

Cons

  • Not compatible with older Nautilus CC, Nautilus (original), or Triton models; verify your robot before ordering.
  • Some users may find the initial fit slightly snug in certain robot models, though it settles over time.
  • Pleated filters may require more frequent rinsing in heavy-debris pools compared to coarse mesh options.
Detailed Review

The SUNRRA Ultra Fine Filters are a versatile replacement option for a wide range of Dolphin robotic pool cleaners, including the Nautilus CC Plus, CC Supreme, M200, M400, M500, and many others. If you own one of these popular Maytronics models and want to improve water clarity, this 4-pack of pleated cartridges is a smart upgrade.

What sets these filters apart is their ultra fine pleated construction. Unlike standard non-pleated cartridges that let fine sediment slip through, the dense pleats trap even tiny particles like algae, pollen, and dust. The result is noticeably clearer pool water and a cleaner floor after each cycle. In real-world use, the filtration performance is excellent, especially for pools that struggle with cloudy water.

The build quality is solid: the frame is made from heavy-duty ABS plastic that resists cracking and tearing, even after repeated rinsing and seasonal storage. SUNRRA claims a lifespan of 2-3 years, which is reasonable if you clean them every 4-6 weeks. The 4-pack also means you have spares on hand, saving you from last-minute replacements.

One important note: these filters are not compatible with the original Nautilus CC, older Nautilus, or Triton series models. Always double-check your robot's model number before purchasing. Also, because the pleats are so fine, they may clog faster in pools with heavy leaf debris; you may need to rinse them more often than coarse mesh filters.

Overall, the SUNRRA Ultra Fine Filters offer excellent value for Dolphin owners who want premium filtration without paying premium prices. The 1-year warranty adds peace of mind, and the 4-pack ensures you're set for multiple seasons. If your robot is compatible, this is a highly recommended upgrade for crystal-clear pool water.

Detailed Review

The Funmit M400 Ultra Fine Cartridge Filter is a 4 pack replacement designed for the Dolphin Nautilus CC Plus and a wide range of compatible robotic pool cleaners. It replaces Maytronics part 9991432-R4, making it a practical option for pool owners who want dependable filtration without the premium price of the OEM part.

The standout feature is the ultra fine pleated filter paper, which captures sand, leaves, hair, and other debris while maximizing surface area. The heavy duty ABS plastic frame keeps the pleats stable during operation and prevents the filter from deforming under water flow, so the cleaner maintains strong suction and consistent performance.

Maintenance is straightforward: rinsing the filter every 4 to 6 weeks is enough to keep it working well, and with proper care each filter can last 2 to 3 years. The 4 pack is especially convenient for owners who clean frequently or have a large pool, because there is always a fresh filter on hand.

The main drawback is compatibility. This filter does not fit several popular Dolphin models, including Nautilus CC, M600, S200, Triton PS, and others, so it is essential to verify your pool cleaner model before purchasing. As an aftermarket part, it also does not carry the original manufacturer branding, though the build quality is solid for the price.

Overall, the Funmit M400 filter replacement offers strong filtration, durable construction, and good value for owners of compatible Dolphin robotic cleaners. If you confirm the fit first, this 4 pack is a smart, budget friendly way to keep your pool clear all season.

Key Buying Criteria for Dolphin Filter Cartridges

Before you purchase a replacement filter, consider these essential factors to ensure you get the best performance and value.

  • Filtration Type: Ultra-fine pleated filters capture microscopic particles like sand and silt, while spring filters are better for large debris like leaves and twigs. Choose based on your pool’s typical debris.
  • Compatibility: Always verify the filter’s part number (e.g., 9991467-R4, 9991432-R4) against your Dolphin model. A mismatch can lead to poor fit and reduced cleaning efficiency.
  • Ease of Cleaning: Look for filters that are easy to rinse with a garden hose. Numbered panels simplify installation and removal, saving you time and effort.
  • Durability: High-quality materials and construction extend the filter’s lifespan, often lasting 2-3 years with proper care. This provides better long-term value.

Frequently Asked Questions

How often should I replace my Dolphin pool cleaner filter?

Typically, you should replace the filter every 2-3 years, but this depends on usage and pool conditions. If you notice reduced cleaning performance or the filter is difficult to clean, it’s time for a replacement.

Can I clean and reuse my Dolphin filter cartridge?

Yes, most filters can be rinsed with a garden hose to remove debris. For deeper cleaning, soak the filter in a mild detergent solution, then rinse thoroughly. However, over time, the filter’s efficiency will decrease, and replacement is necessary.

Are all Dolphin filter cartridges the same size?

No, Dolphin filters come in different sizes and shapes depending on the model. Always check the part number and compatible models list before purchasing to ensure a proper fit.

What is the difference between ultra-fine and spring filters?

Ultra-fine filters capture very small particles like sand and silt, providing crystal-clear water. Spring filters are designed to trap larger debris and are less prone to clogging in heavily soiled pools. Some pool owners use both, starting with the spring filter for big debris and then switching to ultra-fine for finishing.
