How/when to clean the filter of my Philips PowerPro Duo.

1. Remove the filter compartment and take out the filter;
2. Remove the foam filter;
3. Clean the foam filter under a tap with cold or lukewarm water. Let the filter dry for 24 hours.
4. Never put the filter back when the filters are still wet, as this will damage your appliance.

Note: For a thorough clean, you can also clean the dust container and filter parts in cold or lukewarm water.
