The Lasko 3733 is a slim 20-inch box fan with five blades and three speeds, rated for up to 1,800 CFM of airflow. It is built for moving a lot of air through a window, across a room, or alongside an air conditioner, and the fused safety plug and rounded corners are aimed at everyday household use. It does not oscillate and has no remote or timer, so it competes on raw airflow and simple controls rather than features. Owners of Lasko box fans generally treat them as inexpensive workhorses for garages, windows and bedrooms.
