This kit targets owners who want to restore their cleaner's peak performance without the hassle of sourcing individual parts. It is an excellent choice for maintaining a clean pool without professional help.
Standout features include both fine and ultra-fine filter cartridges, allowing the cleaner to trap everything from leaves and twigs to fine sand and dust.

Together, these parts significantly enhance debris collection and overall cleaning coverage.

Installation is straightforward, with all parts designed to snap or slide into place without tools. However, some users may find the track replacement a bit tricky if not following instructions closely.
A potential drawback is the limited compatibility: this kit only works with the Dolphin Nautilus CC Plus model. Additionally, while it covers the most common wear items, it does not include seals or internal parts that may also need replacement over time. Since no consumer reviews are available yet, long-term durability remains unverified.
Overall, the Zymurgoes Tune-Up Kit offers a convenient and cost-effective solution for maintaining a Dolphin Nautilus CC Plus.

- 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.

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.

- Ultra fine pleated media traps both small particles and larger debris effectively
- Reinforced ABS frame keeps the filter stable during operation
- 4 pack provides good value and a longer interval before you need to reorder
- Simple maintenance with periodic rinsing every 4 to 6 weeks
Cons
- Not compatible with many Dolphin models such as Nautilus CC, M600, S200, Triton PS, and others, so check fit carefully before buying

- No customer reviews are available yet, so long-term real-world performance is less proven
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.

Buying Guide: What to Look For in a Nautilus CC Plus Filter
Filtration Type: Fine vs. Ultra-Fine
The most important decision is whether you need fine flat-mesh panels or ultra-fine pleated filters. Fine panels (like those in PUREBURG Fine Filter Panels Compatible) catch leaves and twigs well. They are best for heavy debris and spring opening. Ultra-fine pleated filters trap smaller particles like sand and algae, leaving the water crystal clear. For most pool owners, having a set of both gives you flexibility.
Many brands offer 4-packs of ultra-fine panels that fit the standard frame. The M400 Ultra Fine Cartridge Filters Compatible from Kerneed is a reliable choice for everyday use, while the SUNRRA Ultra Fine Filters Compatible with Dolphin come in an 8-pack for extra longevity. If you want a complete tune-up, the for CC Plus Tune Up Rebuild Kit with 9991433-R4 includes both fine and ultra-fine panels plus brushes and tracks.
Compatibility Check
Not all Dolphin filters fit the Nautilus CC Plus. Some work with older models like the Nautilus CC or Triton Plus. Always confirm the part number. Most replacements use 9991432-R4 (ultra-fine) or 9991433-R4 (fine). The SUNRRA Ultra Fine Filters Compatible with Dolphin (4-pack) clearly states it is not for the original Nautilus CC. Verify your model before ordering to avoid frustration.
Durability and Material Quality
Filter frames made from heavy-duty ABS plastic last longer and resist breaking. Premium filter paper with pleating holds up to repeated rinsing without tearing. The M400 Ultra Fine Cartridge Filter Replacement from Funmit uses thick plastic and fine pleats. Properly care for your filters by rinsing them every 4 to 6 weeks to extend their life to 2 to 3 years.
Value Packs vs. Tune-Up Kits
If you only need filter panels, a multi-pack offers the best per-unit cost. Brands like SUNRRA and Kerneed sell 4-packs and 8-packs. If your cleaner also needs new brushes, tracks, and climbing rings, a tune-up kit like the Tune-Up Kit for Maytronics Dolphin Nautilus CC from Zymurgoes covers everything at once. Evaluate the condition of your cleaner before deciding.
