10. Lasko Twin

Thanks to convenient, snap-on feet, the Lasko Twin adapts well to the floor or a table, which could come in handy in a workshop or garage. It's not an extremely powerful model, but it does a decent job of moving air on a budget.

  • doesn't fit in some small frames
  • easily clogged by dust

9. Cool Works 5280A

While it is a rather simplistic design, the extremely budget-friendly Cool Works 5280A is great for ventilating a small patio or smoking room. It lacks most features, aside from high and low speed settings, but it's decently effective, considering the low cost.
  • rain-resistant construction

Model BWF0522M
Weight 7 pounds
Rating 4.4 / 5.0

All Fans Are Not Created Equal

Window fans have come a long way over the years. As a consumer, it helps to stay on top of what's changed.

For starters, a lot of upscale models now come equipped with their own remote controls. Most of these models also come equipped with a wide range of settings. Certain fans have been designed with built-in extenders, allowing people to secure these units inside a window pane without any risk of vibrating. A lot of window models have also been designed with built-in pegs, allowing people to place the fan on any stable surface regardless of the area. The more settings a fan has, the greater the chances that a person can reverse the stream, circulating air in the opposite direction. A handful of models even come with their own thermostats, enabling a fan to adjust according to the temperature in each room.

Putting all of these features aside, the bottom line is that a fan still needs to operate efficiently. In that spirit, it's worth considering that metal blades circulate air more effectively than their plastic counterparts. It's also worth considering that a fan motor's voltage may be the most reliable way of gauging the power of that model's blast. Finally, it's worth conducting some research on each model's shelf life. Assuming you've found a decent fan, you want it to last.

Dealing With Dust (AKA "Your Fan's Worst Enemy")

Dust is unavoidable if you own and operate a window fan. While you don't need to police dust on a day-to-day basis, you do want to avoid allowing the type of build up that can slow down, or even stall, an average fan's performance. The good news is that keeping a fan clean is easy work. In most cases all you really need is a screwdriver, a vacuum with a hose, some Windex, a roll of paper towels, and maybe a user's manual for the fan (assuming the grates look difficult to take off).

Got all those? Great! You're ready to get started. First, make sure the fan is unplugged. Once you've done that, remove all of the screws along the front and back grates so you can take these grates off. Next, use your vacuum to suck up any dust bunnies that have accumulated in and around the blades and the motor. Now grab the Windex and some paper towels so you can wipe down all of the rotors. Once you've completed the front side, flip the fan over and repeat the same process along the back. Be mindful of the motor's casing. You don't want too much of that moisture to trickle in.

Head outside and work on the grates now. You can use a bucket of hot water to scrub these with a sink brush or a pipe cleaner. You may want to spray them with a hose, as well. Once you have removed all of the dust and mildew, leave the grates to dry. Last step: Screw the grates back on. Your window fan is squeaky clean and ready to go.

A Brief History of The Window Fan

The earliest incarnation of a fan dates back to 500 B.C. These fans were called punkahs, a Hindi variation of the word pankh, which refers to the wind that is created when a bird flaps its wings. The first punkahs were made out of palmyra reeds. The loose materials were woven together, and then operated by hand.

During the Colonial Age the term punkah came to describe a new type of fan. This fan resembled a giant flag, usually designed out of rattan, that swung back and forth from the ceiling, circulating air whenever prompted by a lever. Punkahs were the expressed province of the rich. More often than not, these devices were hung in the houses of aristocrats, where Indian servants, or punkah wallahs, were relegated to operate the levers by hand.

Over the next few centuries researchers and scientists conducted experiments based on funneling airflow and recirculating it to cool an environment. The first significant breakthrough of the modern fan era occurred with the invention of the steam fan. Thirty-three years later (i.e., 1882) the first electrical fans came along, and by the early 20th Century, companies had begun mass producing electric fans for the home.

The industry has grown and shifted during the past 50 years, most notably in response to the widespread use of air conditioning and central air. Despite that, window fans remain a fixture, if not an inexpensive alternative for warmer climates. Today's models range from the ever-reliable box fan to an entire line of upscale fans that include everything from air-quality filtration to thermostat control.
