Experience optimal airflow and convenience with the Smart Twin Window Fan featuring Bluetooth control. Designed for easy operation, this fan allows you to manage settings directly from your smartphone. With two motors that function independently, you can select between intake, exhaust, or air exchange modes. The easy-to-read digital display is adjustable in brightness, and the built-in thermostat automatically adjusts the fan to maintain your desired room temperature. Additional features include an electronic timer set for 8 hours and three whisper-quiet speed settings. This fan fits most double-hung, casement, or sliding windows ranging from 24" to 32" wide and 12" high or larger, thanks to its expanding side panels. It comes fully assembled and includes Lasko's Blue Plug safety technology for peace of mind.
