The Air King 42-Inch Wind Curve Tower Fan with Fresh Air Ionizer moves up to 720 CFM of air from a high-reaching, space-saving design for any room in the home. Three speeds, oscillation, and a built-in ionizer are managed from top-mounted controls or the included remote, which stores on board. A 7-hour auto-off timer helps manage runtime automatically, while a carry handle and base assembly add setup ease.
