If you’re trying to cool a space — be it an apartment or stuffy attic — that doesn’t have central air conditioning, you might find a window fan a more efficient and convenient option than something like a window-mounted air conditioner. For one thing, the best window fans use up far less electricity than an AC, which is better for both the planet and your electric bill. Depending on the size of your AC, a portable window fan can also take up less space and be less obtrusive in the house.
What Are the Best Window Fans?
There are some things to look out for when shopping for the best window fan, however, some of which will depend on your specific needs and space. Window fans come in box and twin models, and they each have their benefits. We like twin window fans because they can both expel hot air from a room and pull cooler air in, reliably ventilating and cooling the space. As far as sheer power goes, however, a single box fan is often the best option — this is assuming ventilation is your primary concern and a little noise isn’t going to be a big deal.
Here are some other factors to consider when shopping for a good window fan.
Reversible: Reversible simply means that the fan moves air in two directions, which allows it to both push hot air out and pull cool air in. Many fans have this feature included automatically; others must be manually turned around.
Power: How much strength you need or even want will probably change depending on the size and use of the room you’re trying to cool. A powerful box fan produces the strongest airflow, but they tend to be noisier. A smaller fan might not blow the skin away from your cheeks, but can be a quieter and milder option for small spaces.
Size: Double check the size of the unit and the size of your window. Basically all fans will include accordion-fold side panels to fit to a standard window, but they are far from one-size-fits-all.
Thermostat: Depending on your needs, a digital thermostat can be a helpful feature on a window fan. Some also include automatic sensors and timers, allowing you to program a precise temperature.
Features: Some fans include extras that we find convenient, but not necessarily essential. A remote control, for example, is nice if you would like to adjust the temperature from the comfort of your couch. If you don’t love the idea of fishing yet another small device from between your couch cushions, however, you can skip it.
