How do I use the Air Extraction and Recirculation modes on a Bosch cooker hood?

You can use your Bosch cooker hood in two operating modes. Air extraction mode or air recirculation mode.

Air Extraction Mode

The air which is drawn in is cleaned by the grease filters and conveyed to the exterior by a pipe system. The air must not be discharged into a flue that is used for exhausting fumes from appliances burning gas or other fuels (not applicable to appliances that only discharge the air back into the room).

• If the exhaust air is to be conveyed into a non-functioning smoke or exhaust gas flue, you must obtain the consent of the heating engineer responsible.
• If the exhaust air is conveyed through the external wall, a telescopic duct should be used.

Air Recirculation Mode

The air which is drawn in is cleaned by the grease filters and an odour filter, and conveyed back into the room. To bind odour in air recirculation mode, you must install an odour filter. To purchase the correct filter for your cooker hood, please refer to your user manual. You can buy the required filters from our online shop.
