The twin sliding panels fit nearly any window with their double-hung window fans. Accordingly, it is easy to install because, while the fan direction is one-way, you can quickly flip the unit around to exhaust a room as well. Moreover, the directional airflow coming off feels like a steady breeze.

Adding a protective cover to your window fan indoor unit is another extra advantage, but when it comes to easy removal of its cover whenever you want, in comparison with other fan types, the cover has to keep cold air out and eliminate any dirt.

Having two powerful turbo-style fans is clearly more powerful than one. It’s also the easiest to control, with a straightforward interface and an individual button corresponding to the fan’s every feature, including speed, temperature, and electronic reversibility—that means, like many good window fans, you can switch from drawing in fresh outdoor air to venting stale or smelly indoor air.
