Abstract: A dirt separator that includes an inlet; an outer wall defining a first dirt collection chamber of a first separation stage; an inner wall defining a second dirt collection chamber of a second separation stage; at least one rib extending from the inner wall into the second collection chamber; and a closure member hingedly connected to the dirt separator and movable between a closed position for sealing open ends of both the first and second dirt collection chambers and an open position for escape of dirt from the open ends. The closure member comprises a seal for sealing against the inner wall when the closure member is in the closed position, and the at least one rib has an end edge that is inclined such that the seal rides along the end edge and onto the inner wall as the closure member is closed.

Abstract: A head wearable air purifier includes a headgear, an air purifier assembly supported by the headgear, a nozzle assembly and a mask body. The air purifier assembly includes a filter and an airflow generator for generating an airflow through the filter. The nozzle assembly is configured to extend in front of a face of a wearer in use. 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 mask body detachably connects to the nozzle assembly and defines a cavity for receiving a mouth and/or nose of the wearer. The cavity is in fluid communication with the air outlet.

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.
