A device includes a housing including an inlet and an outlet, the inlet being configured to intake an infectious agents contaminated air, and the outlet being configured to output a sterilized air. The device also includes a superheating heat exchanger configured to increase a temperature of the infectious agents contaminated air by superheating the contaminated air, the infectious agents contaminated air becoming the sterilized air after being superheated. The device further includes a cooling heat exchanger configured to cool down the sterilized air and direct the sterilized air to the outlet of the housing.
