Abstract
A fan assembly, including a fan body including first and second retention assemblies and an inlet surface defining an air inlet. A motor-driven impeller contained within the fan body generates an airflow. A filter assembly attached to the fan body includes one or more flexible filter media, a first engagement element positioned at first edge of the filter media, and a second engagement element positioned at a second, opposite edge of the filter media. The filter assembly is furlable, and the first and second engagement elements releasably engage with the respective first and second retention assemblies of the fan body to retain the filter assembly tautly over the inlet surface in an at least partially unfurled state, such that, in use, airflow drawn through the air inlet by the motor-driven impeller is drawn through the filter media. The fan body is cylindrical in shape and the filter assembly wraps around substantially all the fan body.
