摘要： A fan assembly, including a fan body including an inlet surface defining an air inlet. A motor-driven impeller contained within the fan body generates an airflow. A filter assembly is arranged to removably engage with the fan body and to cover at least a portion of the inlet surface when engaged with the fan body. The filter assembly includes a filter and a housing for the filter, the housing being provided with a filter retention assembly for releasably retaining the filter in the housing, and a user interface for actuating the filter retention assembly to release the filter from the housing. Upon actuation of the filter retention assembly via the user interface, the filter is free to slide relative to the housing. Preferably, the user interface is positioned on the housing.
