How to choose
Picking the best energy efficient window fan

Compare airflow direction and controls
Airflow direction differs: the shinic, COMFORT ZONE, Seasons and Vornado offer reversible airflow, while the Tornado offers cooling, exhaust and circulation modes. Controls differ too: the shinic and Tornado use remotes, and the COMFORT ZONE reverses by pushing each fan head. Match direction and controls to how you ventilate the room.
Check window fit and placement
Window fit differs: the shinic fits 26.0 to 39.7 inches, the COMFORT ZONE fits 21.6 to 33 inches, the Tornado fits 23.5 to 35.4 inches, and the Vornado fits 26 to 38 inches. The shinic and Vornado mount horizontally only, the Tornado adds a detachable base, and the Seasons adds snap-on feet for floor use. Match the fit to your window, and the base to where the fan sits.
