SAILFLO 10 Inch Window Shutter Exhaust Fan with Reversible Airflow, 297CFM 30W Wall-Mounted Quiet Ventilation Fan Air Intake Extractor for Bathroom Home Bedroom Attic, φ8 Inch Impeller

The SAILFLO 10 Inch Exhaust Shutter Fan is a great ventilation option for small to medium-sized rooms. It has a reversible airflow and can be easily mounted on a wall. The fan is designed to move air efficiently and quietly, and it has a 10-inch diameter propeller. It is made to handle a 300 sq. ft. room, but for specific cubic feet, it's recommendable to ask the manufacturer. The fan is designed for 120v usage and has no remote control. The fan is made in China and some customers complain the quality is low and very thin. However, they also point out that it's suitable for improving ventilation in a room with no other system; to maximize air flow, it's recommended to open a window. Concerning the airflow speed, customers have reported that one click blows it out, the second click blows it in, and a third click turns it off. The fan is safe to use as a shower exhaust fan in a window directly above the side of a shower; it is made to get water on it as it is an inside-outside fan. However, it's not strong enough to filter bad odors.
