摘要： An illustrative example embodiment of an elevator cab air purification device includes a housing having an inlet, an outlet, and at least one air pathway between the inlet and the outlet. A fan module is situated to cause air flow into the housing through the inlet, through the housing, and out of the housing through the outlet. The air flow through the housing includes air flow along the at least one pathway in at least a first direction. An air purifier is situated within the housing and configured to purify air that flows along the at least one pathway before the air exits the housing through the outlet.
