A cleaning device includes a housing, an air driver, an ozone generator, and a catalyst. The housing defines an inlet, an outlet, and an internal cavity connecting the inlet to the outlet. The air driver is positioned within the internal cavity. The air driver is configured to draw contaminated air from an external environment into the inlet and through the internal cavity of the housing to facilitate decontaminating the contaminated air and emitting clean air out of the outlet into the external environment. The ozone generator is positioned within the internal cavity. The ozone generator is configured to generate ozone. The catalyst is positioned within the internal cavity. The ozone and/or the catalyst are configured to interact with the contaminated air to produce the clean air.
