Summary:A wearable air purifier comprises a fan assembly (103, 104, Fig 1) for generating a filtered airflow, and a nozzle 105 couplable to headgear (102, Fig 1), such as a headband. The nozzle preferably coupes to the headgear at opposite sides of the wearer's head to extend across a front of the head. Side portions 412, 413 of the nozzles may be more flexible than a central portion 411 of the nozzle. The nozzle may comprise a front wall 406, and a top wall 407 attached to an upper end of the front wall, extending inwardly toward the wearers head. The top wall may be more flexible than the front wall. A coupling 201, 202 may movably couple the nozzle to the headgear, the coupling permitting movement of the nozzle about i) a first axis between a lowered position and a raised position, and ii) a second axis. In the lowered position the coupling permits movement of the nozzle about the second axis over a first range of movement, and, in the raised position, the coupling is configured to restrict movement of the nozzle about the second axis over a second range of movement which is less than the first.
