Installation FAQs

We can offer you the best cooker hood for any kitchen size. Whether you have an open living-room kitchen or a small, enclosed kitchen.

The cooker hood capacity should always be at least six times the room volume.

Cooker hood capacity = Length x width x height x 6

The CleanAir Module makes your air circulation system more efficient. It consists of a special active carbon filter which lasts twice as long as a comparable carbon filter. With almost the same capacity as a cooker hood in extraction mode, a cooker hood with CleanAir Module is 3 dB quieter.

All Bosch grease filters can be washed in a dishwasher. With cooker hoods, the enclosed inner housing makes cleaning easier, since there are no corners or edges here.

With air extraction, the cooking vapours are extracted by the fan and passed via the exhaust air pipe into the open air or an air flue. With circulating air systems, the cooking vapours are circulated within the room for filtering.

We always recommend choosing the maximum possible diameter of 150 mm. If your exhaust air duct and wall sleeves are smaller than 120 mm in diameter, you may experience higher noise levels from the waste air. In this case, we would recommend a circulating air hood for low-noise operation.

To prevent performance losses, the space between the cooker hood and the wall sleeve should be as small as possible. If the distance is too far, we recommend circulating air for effective operation.

The cooker hood should be switched on before you start to cook. This will ensure that a draft is built up which sucks the cooking vapours upwards.

Extracted air always needs an air intake – which is why adequate ventilation is important. In extractor mode, a window should always be open near the hob. Ask a specialist for advice if you have an additional fire source such as an open fire.
