Worst quality, there were already black crumbs in the bag. I'm not risking using it. Money wasted.

Very catchy title for a simple filter. I didn't even notice the carbon or realize the 3 stages. I received a simple, very basic filter

To avoid making the same mistake as me, the dehumidifier has 2 filters, one plain with activated carbon and another with 3 layers (this one here). Usually, we change the activated carbon filter, which is cheaper (€3) and it is the one that captures most of the dust. It is also slightly larger than the main filter by millimeters.
