It’s a given that household window fans provide a room with cool, fresh air on a hot summer day, but they can also exhaust any stale air out of the house. They can be used as an alternative to expensive air conditioners or else used alongside it if you need a little more cooling power and don’t want to crank up the AC even more. Coming in a range of sizes and with a variety of features.

You can easily find and install a fan that fits perfectly to your windows and provides bonuses like simultaneous exhaust fan power or a thermostat. The best household window fans offer something called electronic reversibility, meaning that you can press a button or flip a switch to make the exhaust and cooling intake go in opposite directions. Many fans can even do these things simultaneously.

CLICK HERE FOR PRICE

Read Customer Reviews Here »

This Holmes Dual Blade twin window fan is slightly smaller than the regular Dual Blade twin window fan. The other has 8.5-inch blades, while this one has 6-inch blades. It is also a lot slimmer. Unlike the original fan, it lacks the thermostat shutdown feature. It has 2 speed settings.

Window Fit

This Holmes Dual Blade twin window fan generally fits slider and double-hung windows. It’s so slim that it can be used while the screen is in place.

Unlike the other Holmes Dual Blade, this fan is only manually reversible. It can be a pain to have to take the fan out of the window if you know you’re going to need to switch up the airflow often.

Value

At $18, the N Dual Blade is less than half the price of the other Holmes Dual Blade twin window fan. It lacks many features, but it’s a shoe-in for people who only need a simple, dependable fan without all the bells and whistles.

Holmes HAWF-2041 Twin

Read Customer Reviews Here »

The Holmes HAWF-2041 Twin fan is quiet enough for the bedroom and nighttime use and has water-resistant motors that remove any worry about rainy conditions. There is a manual thermostat, and it has 3 speed settings.

Window Fit

The Twin fits into most double-hung and slider windows. The extender as well as the bonus extender panel are great for big windows that other fans aren’t large enough to fit into.

Reversibility

This is another fan with independent blades that allow for double intake, double exhaust, or simultaneous intake and exhaust.

Value

For a price of $54, the Holmes Twin is especially valuable for its ability to fit into especially large windows. Other than that, it’s a bit cheaper than some fans that have the same thermostat feature and simultaneous, easily reversible airflow.

10. CoolWorks F-5280A Twin

CoolWorks F-5280A Twin

CLICK HERE FOR PRICE

Read Customer Reviews Here »

The CoolWorks F-5280A Twin is another water-resisting fan, but unlike most fans on this list, it has been deemed too loud for people to sleep while it’s running in their bedroom. It comes with 2 speed settings.

Window Fit

It is 22 inches wide, 4 inches deep, and 11 inches tall with adjustable extenders. It has attachable legs to make it a standalone fan, like the Genesis A1WINDOWFAN AirFlow.

Reversibility

The CoolWorks fan can only be reversed manually.

Value

This is your most basic, no-frills fan, and the $25 you pay will reflect that. Don’t use in a room that’s seriously overheating you, because there are other window fans listed here that have more powerful motors and the ability to cool and exhaust at the same time.

Window Fan Buying Guide

There are a surprising number of things to consider when choosing a new fan for your window frame, but we’ve taken the time to break down the components. You can consider the finer points like remote controls and LED panel thermostats, but those things are ultimately distractions. Basically, it first comes down to whether or not your fan will be secure in your window.

window-fans-image-1

Then, ask yourself if you’ll need to switch the direction of the airflow (cooling and exhaust) often: this is where the term “reversibility” comes in. Finally, if you’re like us, you’ll care about the overall value of the fan and whether you’re getting a good deal. So read on to learn more about these three factors.

Window Fit

Don’t neglect this important detail. Before looking into the cool features like electronic reversibility and automated thermostats with LED panels, the fan has to fit comfortably into one of your home’s windows. A fan in a too large window could very easily fall and break, while a fan won’t even fit into a window that’s too narrow or short.

Also, just barely cramming an oversized fan into a window would make it difficult to remove if there’s a lot of rain or if you’re leaving the house for a long time and don’t want to risk someone getting in through the window. Measurements don’t have to be exact before you buy, because most fans have extenders that can be used to customize the final size of the fan.

They’re also used to close the small gaps to keep out bugs and other small animals. A couple of household window fans on the list, such as the CoolWorks F-5280A Twin and the Genesis A1WINDOWFAN AirFlow, even have detachable legs that can be added to turn them into standalone fans such as a floor fan or countertop fan, and even a great tower fan.

Reversibility

If you’re on the market for a solid fan, our guess is that you’re thinking about how fast it can cool down a room. But what about exhaust? This function gets rid of nasty smells from burnt food, cigarette smoke, or the incense your roommate Chad keeps burning. It also gets rid of the stale air in the room.

The wonderful thing about many fans is that they can cool and circulate at the same time with their independent set of blades (the Bovado USA Twin Window Fan, the Bionaire BW2300-N Twin, and the Holmes HAWF2043 Dual Blade to name a few). But what if you want to switch around the directions of cooling and exhaust?

Sometimes, unfortunately, the whole house window fan will have to be removed from the window and flipped around. This is manual reversibility, and it can be a total pain if you have to do it a lot. On the other hand, electronic reversibility allows easy switching with the flip of a switch or the press of a button on a panel or remote.

window-fan-image-3

If the temperature outside changes rapidly, instead of bringing in cool air you might be bringing in hot air when you really want to push it out. Time to reverse.

Value

Many people wouldn’t dream of spending over $20 for a fan, but it goes almost without saying that an $18 fan can only do so much. It will be smaller, likely made of cheaper plastic instead of metal, with less powerful blades, no way to cool and exhaust at the same time, and you’ll have to forget about electronic reversibility.

These fans are not as durable, not as good at pushing air, and have to be manhandled each time you want to reverse airflow. There are some great fans on our list in the $40 to $60 price range. If you’re serious about cooling down your home, you might want to check those models out.

How to Clean a Window Fan?

These fans don’t take long to accrue dust and grime in the grill and on the blades. To clean your fan up, unplug it and take it out of the window frame. If you’re setting it on the floor or a table, it’s a good idea to put a plastic sheet underneath the fan for easy clean up after. With a screwdriver, take out the screws that are on the edges of the fan and remove the grill cover.

There will be big chunks of matter in the fan that you can remove with your hands. For more detailed cleaning, create a small solution with a cleaner or soap of your choice and some hot water. Then, you can use a rag or sponge with the solution, squeezing out the excess liquid first.

Wipe down the set of blades, grate, grill cover, and knobs. Then take another clean rag or sponge with regular water and wipe away the residue. You can now reassemble your fan and put it back in the window.

How to Install a Window Fan?

Measuring your windows first is a must. The majority of fans on the above list have their ideal window sizes listed. Once you’ve chosen your window and picked the right fan, open the window all the way. If the house window fan is only manually reversible, be sure to put it in with the direction you want the airflow to go in.

You can then close the window against the fan, stretching the extender panels on both sides of the fan so that they fit against the window casing.

How to use a Window Fan?

There are two basic ways to use these fans: with cooling or exhaust. Obviously, if you want a cooler home, set the cooling side of the fan to face inward. You would want the exhaust side inward if you wanted to clear out smoke or other bad smells. Luckily, many fans can switch between cooling and exhaust at the press of a button.

In addition to this, some have dual, independent fan blades that can do both at the same time. Otherwise, you will have to open your window and flip the fan. If you want your fan to blow into your home, make sure there aren’t conditions outside (like lots of garbage or stopped cars) that will bring nasty, stale air in.

Also, putting your fan in a window where there is lots of shade outside of it means that you will be bringing in cool air if that’s what you need.

Conclusion

If you have a room that you fear is larger and/or hotter than what an average fan can cool, there are many fans on our list that go above and beyond. While the $18 Holmes HAWF2021-N Dual Blade or the $25 CoolWorks F-5280A Twin are both at a bargain price on Amazon, they might not get the job done.

On the other hand, the top of the line fans like the $40 Holmes HAWF2043 Dual Blade (with features like its electronically reversible and simultaneous cooling and exhaust, automated thermostat, and water-resistant motor) might be overkill for a small room that already has fresh air conditioners.

window-fan-image-2

You’ll have to ask how often you’ll use the fan. Places with a consistently hotter climate will need a fan that’s incredibly durable as well as easy to clean. Also, where in the house are you using it? Some fans are too loud if they’ll be running all night in the same room that you sleep in.

Do you need an automated thermostat, a remote control, or water resistance? Once you answer all of these questions, you can begin your search in earnest.

Expert Tip

Don’t leave valuable items directly in front of the fan during a rainstorm. Water damage could occur.

Did you Know

You can use the outdoor wind direction to get even more cool air into your home and maintain proper ventilation.
