I bought these in 2024 for my Dolphin Cayman Robotic Pool Vacuum. These filters are a MUST HAVE for your Cayman if you have dirt or algae growing on your pool floor because they keep all those tiny dirt and algae particles inside the basket. The filters that actually came with my robot aren’t fine enough to keep those tiny particles inside the filter basket. Instead, it would vacuum up the dirt and algae and spit it out the back, causing nasty cloudy, dirty pool water. These “nano” filters stop that from happening. They are easy to install and I was worried they wouldn’t fit my Cayman Robot but they do—you just have to remove a couple screws, change the filter walls, and put the screws back in place. Also, I think it should be mentioned that these filters are easy to clean. I spray my filter basket out with a hose after every use and it takes about 30 seconds to get all 4 filter walls clean. I highly recommend these filters for the Dolphin Cayman Robotic Pool Vacuum. They’ve survived a full summer and 3 uses this season, and are still going strong. Review: Definitely captures finer particles. - Impressed. Now, I’ll admit that these are a bit harder to clean than the original screen filters. But….these definitely work better. We tend to get fine silt and other dirt particles sitting on the bottom and this helped. These help pick up finer material and lock it inside the pleated material. It made a difference for our pebbletec surface pool. ## Features - Replacement Ultra-Fine Filter Panels (4 pk) - Compatible with: Active 10, Active 15, Advantage, Cayman, E10, Echo, Encore, Escape, Explorer E20, Nautilus CC, Proteus DX3, Prowler 910, Prowler 917, S100, S50, Solo, T15, T25, Warrior SL. - This part is not compatible with the Nautilus (old), Nautilus CC Pro, Nautilus CC Supreme. - Maytronics Certified Genuine Parts; Keep your Dolphin pool cleaner in top condition ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0745T3WCH | | Assembly Required | No | | Best Sellers Rank | #142,010 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #666 in Automatic Pool Cleaner Replacement Parts | | Brand | Dolphin | | Brand Name | Dolphin | | Color | Black | | Control Method | App | | Customer Reviews | 4.6 out of 5 stars 307 Reviews | | Efficiency | Highly efficient | | Global Trade Identification Number | 00810071221002, 07290018363379 | | Installation Type | robotic | | Item Weight | 0.01 Ounces | | Manufacturer | Maytronics | | Manufacturer Part Number | 9991466-R4 | | Material | Plastic | | Material Type | Plastic | | Model Number | 9991466-R4 | | Required Assembly | No | | Unit Count | 4.0 Count | ## Images ![Genuine Replacement Part — Ultra-Fine Filter Panels (4PK) — 9991466-R4 - Image 1](https://m.media-amazon.com/images/I/81sBOXYTI9L.jpg) ## Questions & Answers **Q: Does this include the basket or is it just the replacement filters?** A: Just the filters. **Q: These look like the ultra fine. But the pics in comments say fine. The one that came with robot is see through and garbage. is this ultra fine?** A: It is ultra fine. And it’s excellent. Personally, I bought another basket with the ultra fine so I have a basket with ultra fine panels and one with the large debris panels. This was the first year I used the large debris panel basket. It worked like a charm clearing my pool of large amounts of leaves and debris at the beginning of the season. You may want to try it next year. Like you, I thought it useless! **Q: can i just buy the ultra fine panels to change out with the basket panels that come with dolphin nautilus or do i need the entire basket?** A: You just change out the coarse filters that it came with :) Same basket. **Q: Will this fit the Dolphin T15 ?** A: I own the Dolphin, and purchased the refill, and they do fit. ## Customer Reviews ### ⭐⭐⭐⭐⭐ These filters solved all my pool vacuuming problems! *by A***R on June 8, 2025* The video shows what the filters collected in the filter basket from cleaning my pool floor; and the photo is the same filter basket after I sprayed that gunk out with a hose.
