Abstract: A wearable air purification system having a wearable support configured to be supported on a user's head. The wearable support is attached to an air delivery mask which delivers a flow of air to an air delivery region. A motor for driving the flow of air to the air delivery region is mounted on the wearable support, or on the air delivery mask, and an air filter for purifying the flow of air is mounted on the wearable support, or on the air delivery mask. Each end of the air delivery mask is moveably connected to the wearable support so that the wearable support is able move with respect to the air delivery mask from a deployed position to a stowed position. The volume envelope of the wearable air purification system is larger in the deployed position than in the stowed position.

Abstract: A wearable air purifier including a headgear; an air purifier assembly, the air purifier assembly configured to generate a filtered airflow from an outlet aperture thereof; and a nozzle assembly connected to the headgear by a hinge assembly. The nozzle assembly includes an inlet aperture for receiving the filtered airflow from the outlet aperture of the air purifier assembly and an air outlet for emitting the filtered airflow from the nozzle assembly. The hinge assembly is configured such that the nozzle assembly is movable relative to the headgear between first and second configurations, filtered airflow is emitted from the air outlet in the first configuration and filtered airflow is not emitted from the air outlet in the second configuration.
