Abstract: A head wearable air purifier is provided. The head wearable air purifier includes a first speaker assembly and a second speaker assembly. The first speaker assembly includes a filter assembly, a motor-driven impeller for creating an airflow through the filter assembly, and an air outlet downstream from the filter assembly for emitting a filtered airflow from the speaker assembly. The head wearable air purifier further includes a nozzle and a control circuit. The nozzle is arranged to receive the filtered airflow from the first speaker assembly. Further, the nozzle includes an air outlet arranged to emit the received filtered airflow from the head wearable air purifier. The control circuit is arranged to control a rotational speed of the motor-driven impeller of the first speaker assembly such that the maximum rotational speed of the motor-driven impeller is from 9,000 to 18,000 RPM.
