My Dolphin came with fine filters. Are there finer filters available for my Dolphin?

The answer

What to know.

Multilayer filter with pre-filter (30 microns)

Your Dolphin robot comes with fine spring filters (100 microns) that remove large debris including leaves and twigs.

Depending on your model, it also consists of another set of ultra-fine filters (50 microns) that clean small particles like sand, dirt, and algae.

Some robot models have an additional spring filter that can be added to the ultra-fine filter basket for super filtration (30 microns). More and see if it is compatible with your robot model

The fine spring filters should be used for the initial opening season cleaning and if you have large debris in your pool. The ultra-fine filters should be used if you have mainly small debris and algae in your pool.

Click the user manual to refer to the user manual to verify which filters come with your robot and for illustrations on how to replace the filter panels.

If you wish to purchase a set of ultra-fine filters (for fine debris, such as algae) for your robot, please visit our Dolphin Spare Parts & Accessories page or check with your local Dolphin dealer if they sell replacement filters.
