# The 20" Weather ShieldŽ Box Fan with Thermostat keeps you cool while restraining energy costs! Thanks to its built-in thermostat, it only runs until the room reaches the desired temperature, and then automatically turns on or off to maintain that temperature. It has three whisper-quiet speed settings, so you can adjust its performance to any situation! Its effectiveness is enhanced by a Patented Weather Shield motor for worry-free window use, a wider body for greater floor stability, and easy-to-use controls located on the handle.
