Abstract: A wearable air purifier includes a headgear, an air purifier assembly, and a nozzle assembly. The air purifier assembly includes a filter and an airflow generator for generating an airflow through the filter. The nozzle assembly includes an inlet aperture configured to receive a filtered airflow from the air purifier assembly, and an air outlet for emitting the filtered airflow from the nozzle assembly. The nozzle assembly includes a first end section connected to the headgear, a second end section connected to the headgear, and a midsection connected to the first end section by a first hinge and connected to the second end section by a second hinge.

Abstract: A head wearable air purifier has a headgear, and an air purifier assembly supported by the headgear, the air purifier assembly having a filter and an airflow generator for generating an airflow through the filter. The head wearable air purifier has a nozzle assembly having an inlet aperture configured to receive a filtered airflow from the air purifier assembly, and an air outlet for emitting the filtered airflow from the nozzle assembly. The nozzle assembly includes a first end section connected to the headgear, a second end section connected to the headgear, and a midsection connected to the first end section and the second end section. The first end section has a first portion pivotally connected to the midsection about a first pivot axis, and a second portion pivotally connected to the first portion about a second pivot axis substantially orthogonal to the first pivot axis, the second portion connected to the headgear.

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.
