Abstract
There is provided a fan assembly comprising a motor-driven impeller arranged to generate an airflow, an air outlet arranged to emit the airflow, at least one filter assembly that is arranged to purify the airflow, a plurality of sensors arranged to measure a value for each of a plurality of air quality characteristic, and a processor. The processor is configured to receive measured values for each of the plurality of air quality characteristics, identify one of a corresponding set of intervals within which the measured value falls, select an air quality index value associated with the identified interval, and generate a corresponding speed value using the selected air quality index value. The processor is then configured to set a speed of the motor-driven impeller in dependence upon the highest of the speed values.
