Frequently Asked Questions

Which BWT Cosmy models is this filter compatible with?

This outer filter is compatible with all BWT Cosmy robotic pool cleaner models, including the Cosmy 100, 150, 200, 250 and Cosmy Star.

What does 100 micron filtration mean?

100 micron refers to the size of the mesh openings in the filter. At 100 microns, the filter captures fine debris including sand, dust, algae spores and small particles that coarser filters may miss.

How often should I replace the outer filter?

BWT recommends inspecting the filter after each use and replacing it when the mesh shows signs of wear, tearing or reduced flow. Regular rinsing after each cycle extends filter life significantly.

Is this a genuine BWT part?

Yes — this is a genuine BWT replacement part (part number 125536148), sourced directly from BWT to ensure correct fit and performance in your Cosmy robotic cleaner.

How do I clean the filter between replacements?

Remove the filter basket from the robot, rinse thoroughly with a garden hose, and allow to dry before reinserting. Avoid using high-pressure washers as this can damage the mesh.
