Our Verdict
The Genesis is a simple way to get thermostat control without paying for a remote or app.
It has no remote, and at 8.4 pounds it is heavier than most twins.

Design
Expandable side panels add 6.5 inches on each side.

Controls
Three speeds: low, medium and high.
The thermostat ranges from 60 to 80 degrees, with LED lights showing the setting.
Placement Tips
Measure the window before you install and close any gaps with the expanders or foam provided, so the fan moves air through the blades rather than around them. Use the window lock or a stop if you leave it in an accessible window.
For a cross breeze, run this fan on intake in a window on the cool, shaded side of the house and open a window on the opposite side, or set it to exhaust upstairs to pull cool air in below.
Running Costs and Care
Unplug the fan and wipe dust from the grilles and blades every few weeks during heavy use. Dust buildup cuts airflow and adds noise.
Bring it in or close the window in heavy rain unless the listing says it is weather resistant, and store it clean and dry over winter.
How It Compares
Against the shinic 4-Speed Thermostat Window Fan, the Genesis costs less but lacks a remote and timer.
Against the Comfort Zone Triple Window Fan, the Genesis reverses while the Comfort Zone adds a third fan.
