AEG 8709D-B is a cooker hood that can be used as an extractor or filter version. As an extractor, it has 9 fan speeds that can be set using the control panel on the front of the hood. There's also a high-speed setting (P) and a 15-minute fan timer.

One of the unique features of the AEG 8709D-B is that it can be used with activated carbon filters to remove odors and pollutants from the air. When the activated carbon filters need to be changed, the display on the control panel will show a "C" to alert the user. The display will also show an "F" when it's time to change the grease filters.
