1. A method of treating air with a movable air treatment system, comprising:
positioning the movable air treatment system in a room, wherein the movable air treatment system has a wheeled housing with a length, a height and a width, wherein the length extends between a first end and a second end and is greater than the height and the width, the wheeled housing having an air inlet and first wheels adjacent the first end, an air outlet and second wheels adjacent the second end and an enclosed space defined between the first end and the second end, wherein the wheeled housing has a longitudinal axis extending parallel to the length and generally aligned with a floor of the room, the wheeled housing being movable via the first wheels and the second wheels to orient the air outlet in a desired direction within the room;
generating an airflow;
introducing the airflow through the air inlet in the wheeled housing;
directing the airflow through the enclosed space defined in the wheeled housing and past at least one baffle in the enclosed space that is configured to impart turbulence to the airflow;
exposing the airflow to ultraviolet light within the enclosed space for at least 0.3 s as the airflow travels at a flow rate of at least 1000 ft3/minute; and
conveying the airflow from the wheeled housing via the air outlet in the desired direction into the room; and
wherein at least 99% of virus particles entrained in the airflow are deactivated by the exposure to the ultraviolet light inside the enclosed space of the wheeled housing.
