Bosch chimney cooker hoods are wall-mounted extractors that sit above the hob with a vertical flue running up to the ceiling. The range covers Series 2, Series 4 and Series 6 models in 60 cm, 75 cm and 90 cm widths, so there are options for a compact four-burner hob and for a wider range cooker. Every one can either duct air outside or run in recirculation mode with filters, which helps if an outside wall isn't practical.

Series 2 is where you'll find the classic pyramid-shaped hoods in stainless steel. They have three speed levels, push button controls and extraction of up to around 380 m³/h, which is enough for everyday cooking in a modest kitchen. Series 2 also includes black chimney hoods with a stronger motor. Series 4 moves to a straight-edged box design in stainless steel or black, with three speeds plus a booster and a maximum normal extraction rate of 594 m³/h. The Series 6 box hoods are black, have an A++ energy rating and run more quietly, starting from 43 dB, with a booster for bursts of up to 699 m³/h when you're searing or stir-frying.

The trade-off is fairly simple. Higher series cost more to buy, but you get more power for open-plan spaces and lower noise when the hood runs for long spells. Energy ratings range from D on the pyramid models to B on most of the box designs and A++ on Series 6.

To narrow your choice, match the hood's width to your hob or slightly wider, then decide between the pyramid and box shapes and choose your finish. If your kitchen is large or open-plan, look at the Series 4 and Series 6 extraction figures. If a chimney design doesn't suit your layout, see the Bosch angled hoods or Bosch integrated cooker hoods, or compare every style in Bosch cooker hoods.
