Sometimes you can't even enjoy the sound of sizzling in the pan because the range hood is far too loud. With the use of a high-performance fan and optimized airflow within the range hood, a Bosch range hood featuring EcoSilence Drive motor technology operates significantly quieter and saves over 80% energy. The motor causes no mechanical friction, resulting in not only less operational noise but also improved longevity. This is based on an average fan operating time of one hour per day on level 2 and two hours per day of lighting being on.

So you can converse undisturbed while cooking, Bosch range hoods are so quiet that you will hardly notice them. Typically, noise is generated by the motor's own sound and the airflow, depending on back pressure and the motor's power. In exhaust mode, much of the noise is expelled through the exhaust duct. In recirculation mode, the noise level can be reduced by an additional 3 dB(A) using the special activated carbon filter in the CleanAir module and special insulation.

Metal grease filters are required for both exhaust and recirculation hoods to filter grease and other solids from the air being drawn in. To maintain high effectiveness, they should be cleaned by hand or in the dishwasher about once a month. Whether you have an open-plan kitchen or a small closed kitchen, Bosch offers the optimal fan performance for every kitchen type. For a consistently pleasant indoor climate, the air should be completely exchanged 6 to 12 times per hour. To achieve this, the air flow rate or the performance of the range hood must match the room volume.
