Which robots take NanoFilters
Included on the ProLine, an upgrade on the Max-Series.
Filter material can develop tears, and frames or baskets can crack. Fine and ultra-fine describe the filtration level, with ultra-fine filters catching smaller debris. This category includes panels, bags, baskets and assemblies. Match the filter style your robot uses, not just the ultra-fine label.
Start with your exact robot model and compare the number on your old part with the listing. Each part's page shows which robots it fits, and each robot has a parts page you can check. Package sizes also vary, including four-panel packs and front-and-rear kits. Confirm both the fit and the listed quantity before ordering.

Questions
NanoFilters, answered.
Which robots are Poolbots' NanoFilters sold for?
Poolbots offers Gen-2 ultra-fine filter panels and MaxBin kits in its NanoFilter line for the Dolphin Premier, Sigma, Quantum, Cayman and Escape on separate product pages. This category also lists Maytronics ultra-fine parts for other Dolphin models.
Will any ultra-fine filter fit my Dolphin or Niya?
No. The category covers 70 Dolphin and Niya models, but each part has its own compatibility list. Search by your exact model, then check the part's page or your robot's parts page before ordering.
How often should I replace ultra-fine filter panels?
Use the filter's condition to guide replacement rather than assuming a set number of seasons. Check for tears, cracked frames and damage that prevents a secure fit. Ask Poolbots' pool experts if you're unsure which component needs replacing.
Does Poolbots sell every filter listed on this page?
Some listed parts are available directly from Poolbots. For the others, Poolbots can help you source the part. Reach Poolbots' pool experts through live chat or by phone for help finding the correct replacement.
