Bosch DIB091K50B Island Cooker Hood, Stainless Steel

Never knowingly undersold

Product information

Designed for ceiling mounting above an island hob, the Bosch DIB091K50B cooker hood offers high extraction rates for 90cm-wide hobs. It is a rim-type unit with sensor control and it has an A energy rating.


Touch-sensitive controls operate the three-speed fan, which also has two intensive settings. A sensor detects when cooking fumes become intense and automatically switches on the boost power levels to increase the extraction rate. After six minutes's high-power extraction, the hood returns to the regular setting. It also has an automatic ten-minute run-on after cooking has finished.


The hood captures grease, odours and steam through two metallic grease filter cassettes. A grease saturation indicator shows when the filters need cleaning. They are easily removed and cleaned in a dishwasher.

Energy rating

This Bosch hood has four low-energy LED lights to illuminate the cookto and an A rating for energy efficiency. It is also A-rated for fan and lighting efficiency, and B for grease filtering.

Air circulation mode

This chimney hood can be converted to run in recirculation mode, provided there is an adequate air intake. Air circulation operation also requires an activated carbon filter. Bosch offers a conversion kit for recirculated extraction.
