- Built Exclusively for Dolphin Sigma
- A Deeper Clean - NanoFilters clean deeper than the standard filter. Intricately woven NanoTech material captures microscopic debris and contaminants at a micron level far smaller than Standard Dolphin Filters
- Greater Surface Area - With a much larger surface area, Nanofilters capture far more waterborne debris while maintaining a relatively low resistance to waterflow.
- Improve your Pool's Water Quality - Stop it at the source by removing a large amount of contaminants before it ever gets to your pool’s main filter
- Advanced Tech - The basic filter found on most pool robots is a large open pore plastic mesh which is first generation technology. NanoTech micropore pleated filters efficiently removes far more contaminants from the water
- Tough on Oil - When oil and other microscopic debris is caught in the robot’s Nanofilter, it forms a transparent sheath over the trapped debris. This gunk is then washed off when the filter is cleaned, providing a valuable method to improve turbidity and improve the transparency of the water.
