摘要： Provided is a wearable air purification device (100) for delivering purified air for a wearer (102) of the wearable air purification device to breathe. The wearable air purification device comprises an air treatment unit (104) for treating ambient air in order to generate said purified air. Purified air for the wearer to breathe is displaceable towards the wearer along a first flow path (106). Ambient air, in other words air that has not been treated by an air treatment unit of the wearable air purification device, is displaceable along at least one second flow path. An air displacement assembly (110, 112) generates airflow along the first flow path and along the at least one second flow path. A Peltier element (114) comprises a first side and a second side. The Peltier element is configured to provide cooling at one of the first and second sides when providing heating at the other of the first and second sides. The first side and the first flow path are arranged to enable heat exchange between the first side and air being displaced along the first flow path. The second side and the at least one second flow path are arranged to enable heat exchange between the second side and the ambient air being displaced along the at least one second flow path.
