Keep Your Flagship Dolphin Sigma Polishing Water Like Day One
Microscopic Silt & Algae Trap
Captures fine dust, plaster silt, yellow pollen, and dead green algae down to ~2 microns.
SnapLoc™ Sigma Exact Fit
Clicks directly into the Dolphin Sigma's top-loading SnapLoc™ cartridge frames.
Full Triple-Motor Flow
Expanded pleated surface area preserves strong wall-climbing suction without premature clogging.
Polishes Water Clarity
Strips out fine suspended particles that make night pool lights look cloudy.
Reduces Main-Filter Backwashing
Stops fine debris inside the robot before it reaches your main pool pump.
Reusable Multi-Season Build
Rigid frames and washable pleats rinse clean with a garden hose.
Exact OEM Sealing for Your Dolphin Sigma
Off-brand knockoff panels often warp or leave small corner gaps that let fine dust bypass straight into your Sigma's impellers. This genuine NanoFilter™ set for the Dolphin Sigma locks tightly into your top-load SnapLoc™ frames to restore razor-sharp water clarity.

Sigma NanoFilters FAQ
Do these fit directly into the Dolphin Sigma's existing filter baskets?
Yes—simply unclip your worn panels from the Sigma's SnapLoc™ frames and snap these genuine NanoFilter™ panels right in.
Are these better than standard mesh for cloudy water?
Much better—standard mesh catches leaves and bugs, while pleated NanoFilters™ capture fine dust, pollen, and dead algae.
