The Comfort Zone Triple Window Fan uses three fans instead of two, lets you run one, two or all three, adds an adjustable thermostat and mounts horizontally or vertically. For more models, see our Window Fans page.
Our Verdict
For flexible airflow on a budget, the triple fan is a clever pick, and the vertical mount suits sliding windows.
The listing does not mention reversible airflow, and controls are manual.

Controls
A manual dial sets three speeds and how many fans run.
An adjustable thermostat dial helps hold a steady temperature.
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 twin fans, the triple fan offers finer control over airflow.
Against the Genesis Twin Window Fan with Thermostat, the Comfort Zone adds a third fan while the Genesis reverses.
