The Genesis A1 window fan stands out as one of the best window fans on this list, with its easy portability and cost-effectiveness. The Bionaire window fan is also a good option because of the brand's trust and reliability. The Comfort Zone CZ310R window fan is another good option because of its easy controls and installation.

Window fans offer a cheap and efficient solution to cool your rooms during the summer heat. Options in this segment are aplenty, but not every fan is suitable for everyone’s needs. And I, for one, believe in being thorough before buying anything that plays a crucial role in comfort.
That’s why I’ve reviewed 11 of the best window fans on the market today. Make sure you go through all the reviews and the attached buyer’s guide to make a wise decision.
Best Window Fans
Here's the list of the 13 best window fans to ward off the heat, featuring a range of options to suit your cooling needs and preferences.
1. Bionaire Window Fan - Best for Remote Control
What I like
- Remote control included
- Reversible blades
- Easy-to-read controls
- Low noise level
What I don't like
- No freestanding option
This window fan from Bionaire has twin 8-inch reversible blades that draw in cold air and expel hot air outside. The thermostat is adjustable, so the fan will draw in or expel air according to your set temperature settings. The user interface is easy to read and makes it very easy to control the three fan speed settings.
The window fan can produce airspeeds as high as 11 mph, which feels like a decent breeze even if you’re standing 20 feet away. The fan is also pretty quiet, having a noise level of only 30 dB.
There are just a few things to keep in mind. This window fan fits best in double-hung windows, with the optimum width being between 24 and 37 inches. I also found that the working range of the remote control provided is just around 15 feet.
Product Dimensions: 25.5 x 14.1 x 6 inches | Item Weight: 8.4 pounds | Price: $70 | Type: Twin fans
2. Genesis Window Fan - Best for Portability
What I like
- Freestanding option
- Easy installation
- Portability
- Durability
What I don't like
- Cheap plastic material
The Genesis A1 window fan is one of the best window fans on this list. It has a built-in thermostat with a temperature range of 60 - 80 degrees Fahrenheit. The fan works on a dual motor system, with two 9-inch fan heads with copper motors. The copper ensures durability and resistance.
The airflow is reversible as well, designed to intake or expel air simultaneously. The fan also features three speed settings: low, medium, and high.
The fan is also easily portable since it has an easy-to-carry handle built into the back of the unit. It can also be used as a freestanding model by attaching the two removable legs that come with the product.
Additionally, the fan is easy to install. It comes with expandable side panels that can pull out up to 6.5 inches on both sides and lock into place perfectly on a window frame of any size. It is also less noisy compared to the Bionaire window fan.
Product Dimensions: 12 x 24 x 4 inches | Item Weight: 8.4 pounds | Price: $46 - $47 | Type: Twin fans
3. Comfort Zone Window Fan - Best for Easy Control
What I like
- Easy to control
- It can also function as a standalone fan
- Simple installation
- Remote control included
What I don't like
- Not very powerful
This Comfort Zone window fan provides you, as is apparent from the name, comfort in terms of control and functionality. The product includes a remote control to change the temperature settings and fan speeds from a distance.
This window fan also comes with multiple functions, like the cooling function to cool a room, the exhaust function to refresh a room, and the circulating function to move the blades on each fan in opposing directions.
This fan is one of the easiest to control because of the simple control panel. You also get a remote control to change the fan settings, but the control panel makes the usage of the remote pretty obsolete. Unless you wish to control the fan from a distance, the control panel is pretty good.
The fan is also easy to install in any window frame, as the Accordion adjusters can fit in any window between 23 ½ and 37 inches in size. It also comes with removable feet, so it can act as a standalone fan on any window sill.
Product Dimensions: 25.7 x 5.6 x 14.6 inches | Item Weight: 6.62 pounds | Price: $45.68 - 54.95 | Type: Twin fans
4. Vornado Transom Window Fan - Best for Low Noise Level
What I like
- Low noise level
- 5-year warranty
- Sleek look
- Powerful airflow
What I don't like
- Tricky installation
The Vornado Transom window fan is a pretty low-profile and quiet window fan that is perfect to be installed in any room in your house. It uses its powerful airflow to expel stale indoor air and bring in fresh air from the outside. It also operates on a very low noise level, about 46 dB.
Additionally, the fan comes with 4 fan speed settings, automatic temperature control, and a handy remote control. It’s also electronically reversible, meaning just a touch of a button can quickly transition the mode from fan to exhaust.
The fan uses the patented Soft-fit foam system for installation. It is designed to fit perfectly in any single-hung or double-hung window, measuring between 26 - 40 inches in width and having a minimum opening of at least 8 inches.
Talking about the installation process, I found that the weather-tight extension blocks made the installation quite tricky. But the digital display and 5-year warranty more than makeup for it. Just make sure you have extra help while installing the fan.
Product Dimensions: 5.7 x 26 x 7.2 inches | Item Weight: 8.3 pounds | Price: $119.99 | Type: Dual blades
5. Air King 9166F Window Fan - Best for Powerful Air Circulation
What I like
- Storm Guard feature
- Easy operation
- Powerful air circulation
- Three-speed settings
What I don't like
- Screw-in installation
The Air King 9166F window fan is powerful, moving enough air to freshen up any room. The window fan is equipped with 3-speed settings, a single-phase motor and sleeve bearing, permanent split capacitor. The fan control settings are pretty simple, with intake/exhaust functions and high, medium, and low-speed levels.
The air movement at the highest setting is claimed by the manufacturer to be 3560 cubic feet per minute. You’ll have to control all this with a switch mounted on the front of the fan since no remote control is included.
The best feature of this window fan is its Storm Guard feature, which enables the window to be closed behind the fan during bad weather, or when locking the entire house. This means you can leave the fan in place whether the window is opened or closed.
However, this feature requires the fan to be carefully screwed into its place, which can complicate the installation process unless you’re skilled in DIY.
Being such a powerful fan, it has comparatively high noise levels. It is also quite expensive compared to the other window fans on this list. But that should be worth it if fast cooling and circulation are your top priority.
Product Dimensions: 26.75 x 11.25 x 26.25 inches | Item Weight: 8.16 pounds | Price: $188 | Type: Single fan
6. Sharper Image Portal Window Fan
What I like
- Easy installation
- Weather resistant casing
- Powerful airflow
- Reversible exhaust
What I don't like
- No remote control
The Sharper Image portal window fan also has powerful air circulation and strong airflow, pulling in cool fresh air from the outside and exhausting hot stale air. Its reversible exhaust helps change airflow from fan to exhaust and vice versa with just one touch of a button.
It comes with a weather and UV-resistant case, meaning it can serve you with cool air irrespective of the weather. Additionally, the fan uses button controls, giving you easy access to the 3 fan speeds and the reversible functions.
The installation process is made super simple by the innovative modular block system, so it seamlessly fits into your window. On top of that, its sleek appearance completely blends in with the room. The window view is not blocked either since the fan’s height is only 6.58 inches.
Just keep in mind that the required width of the window frame is between 24 and 38 inches, while the minimum window height is 8 inches. Also, the noise level is pretty low, going only as high as 52 dB.
Product Dimensions: 6.1 x 23.9 x 6.5 inches | Item Weight: 8 pounds | Price: $88 | Type: Twin fans
7. Air King 9155 Window Fan
What I like
- Storm Guard feature
- Durable blades
- Less noise level
- Includes required hardware
What I don't like
- Less powerful
The Air King 9155 window fan has powerful 16-inch blades, providing effective air circulation and airflow. This helps with bringing in the outside fresh air, leaving your room’s air cleaner and more breathable.
This fan features convenient manual controls, which are mounted on the front of the fan. You can use these buttons to easily switch between the 3 fan speed settings and the intake/exhaust mode. The blades are durable, as they are covered and protected by a high-impact styrene housing and metal front grill. Despite this, the fan is relatively compact.
Similar to the other Air King models on this list, this window fan also has a Storm Guard feature, allowing you to leave your fan installed irrespective of the weather. But the air movement on the high mode is significantly less than the other Air King model, reading at 2470 cubic feet per minute. This, however, does mean lesser noise and disturbance.
The installation is pretty simple since the fan comes pre-assembled. Plus, all the hardware you need is already included in the product box itself.
Product Dimensions: 26.5 x 8.25 x 22 inches | Item Weight: 6.17 pounds | Price: $115 | Type: Twin fans
8. Amazon Basics Digital Window Fan
What I like
- Easy installation
- Removable feet
- Compact size
- Remote control included
What I don't like
- Less airflow
The Amazon Basics Digital window fan is a standard window fan with two fan heads measuring 9 inches in length. It has powerful copper motors that offer optimal air circulation in small to midsize rooms.
It also has an adjustable thermostat with 3 fan speeds, enabling you to have the cooling you want. Apart from that, the reversible airflow blades enable both exhaust and fan modes. So, the fresh air is brought in from the outside, while the stale inside air is expelled out.
The window fan also has removable feet so that the fan can function as a standalone fan as well.
The installation is pretty simple. The fan has expandable side panels that can fit into most standard windows, the required width being between 25 and 32 inches. There is also a carrying handle in the back to enable portability.
Product Dimensions: 5.35 x 23.43 x 12.6 inches | Item Weight: 5.72 pounds | Price: $49.72 | Type: Twin fans
9. Lasko Window Fan
What I like
- Bluetooth connectivity
- Easy installation
- It can be converted into a table/ floor fan
- Reversible exhaust
What I don't like
- Not very powerful
The Lasko W09560 is a reversible twin-window fan unit with three separate speed settings, intake/exhaust settings, and air circulation systems. Each of the 9-inch blades can be programmed independently to either push hot indoor air outside or to intake the cold outside air.
A unique feature of this window fan is that it is Bluetooth-enabled. So, even though a remote control is included with the fan, you can just control the fan using your phone. The app is available on both Android and iOS and can be used by following simple instructions.
Installation is straightforward, as the fan comes fully assembled and ready to use. The extension panels slide in and can fit in both horizontal and vertical window openings. The fan also features an electronic 8-hour timer, which makes the fan pretty energy efficient.
However, the digital controls were a bit challenging to use, even with the adjustable brightness. But if you have Bluetooth control enabled, this issue will hardly matter. Apart from that, the fan is less powerful than some other options on this list.
Product Dimensions: 5.41 x 24 x 12.9 inches | Item Weight: 8.15 pounds | Price: $80 | Type: Twin fans
10. Shinic Twin Window Fan
What I like
- Easy installation
- Remote control included
- Three modes
- Removable feet
What I don't like
- Not very powerful
The Shinic Twin is a reversible window fan with three modes of fan blades. The Cool mode helps keep the room cool with the blades facing inwards. The Exhaust mode helps to exhaust stale air. The Circulate mode helps with adequate air circulation.
The speed of the twin fan has three different settings: low, medium, and high. Additionally, the fan also comes with a remote control. So you can easily control the fan from a distance.
The installation is pretty simple as well. The fan has an expandable panel that can be attached to any window. The supported window width is between 23.5 and 37 inches. Besides, the fan comes with handles and removable feet, which make it easy and convenient to move the fan around.

11. Joey’z Twin Window Fan - Best For Portability
What I like
- Reversible blades
- Remote control included
- Easy installation
- Built-in handle
What I don't like
- Only two-speed settings
The Joey’z twin fan is reversible, having a manual reverse option. The twin blades can remove hot air from inside the room and draw cool air from the outside. It also has removable legs so that it can be used as a floor or a desk fan as well.
Additionally, the fan is pretty easy to install. The auto-locking accordion expanders can fit in most standard windows, and the built-in handle makes it convenient to carry the fan from one room to another.
The product also includes a remote control, but the control panel present on the fan will enable it to function perfectly without the remote as well.
However, the fan has only two speed settings. You can either choose a low-speed option for a gentle breeze or a high-speed option for a brisk breeze.

Buying GuideFor The Best Window Fan
After going through all the above products, you might be a little confused about which fan will suit your needs the best. Hence, this buyer’s guide will help you know what points to look for when buying a window fan.
Number Of Fan Speeds
The number of fan speeds will help you determine the cooling power of your window fan. You can check out the CFM of the fan, which stands for cubic feet per minute. This number tells you how much air is moved by the fan in 60 seconds. Hence, the more the CFM, the better the air circulation.
Most of the window fans on this list have three-speed settings, which are suitable for mid to big-size rooms. The two-speed window fans are best for small rooms since they move less air.
Reversibility
Reversibility helps to circulate air throughout your room, expelling warm air and bringing in cold air. Some fans are electronically reversible, so you can move between the intake and exhaust functions using buttons or remotes. Some are also manually reversible, meaning you’ll have to remove the fan, flip it, and reinstall it into the window.
Obviously, the former is much more convenient. Using electronic reversibility, you can change between the two functions with just a touch of a button.
Noise Level
Window fans (as well as ceiling fans) produce a noise, which is known as white noise. Many people do prefer to have this white noise. Other people, on the other hand, are not so welcoming. So, if you’re one of those people, be sure to check out the noise level of your fan.
As expected, the most powerful window fans are also the loudest, with the Air King going as high as 76 dB. For lower noise (and lower power), the best options are the Holmes and the Bionaire window fans.
Remote And Control Panel
Many of the models mentioned on this list come with a remote, meaning you don’t have to physically get up to change the fan settings. So, if you’re placing the window fan in an area that isn’t easily accessible, a remote control might be the best option for you.
If the fan is going to be placed on your desk or is in an accessible area, you can make do without the remote control and just use the actual control panel on the fan.
Portability
If your window fan is going to be moving around in between rooms, you might want to think about portability. Look for a fan that is lightweight, compact, and has removable legs. This will help you conveniently move the fan from one place to another. The removable legs will also help you convert your window fan to a desk fan or a floor fan.
Additionally, in case you move out of your place, it can’t hurt to have a fan that is compact and lightweight to move.
Installation
No one wants to spend a lot of money on the installation of their window fans. So, look for a model that is easy to install and comes with an instruction manual. Almost all the window fans on this list come with easy installation procedures, making installation a breeze.
Some of these fans just sit between the sash and sill of the window, while others need to be screwed into place. Other fans are designed so that the window sits on top of them, holding them in place, while some have panels that extend on the side to cover gaps. So, make sure you buy one that suits your needs and your window frame.
Number Of Internal Fans
Window fans can either be a one-fan unit or a twin window fan. One-fan units have a big centralized fan and have a stronger airflow. However, they are bulky and cool the room more slowly than the twin fan units.
A twin window fan has two small internal fans side-by-side. As expected, they are much more efficient than the one-fan alternatives. Additionally, you can program the individual fans independently to make them perform different functions at the same time, like the intake and exhaust functions. This feature can be seen on the Lasko W09560 window fan.
How do window fans cool a room?
Window fans help to reduce the temperature in a room. This is done by either using the exhaust fan to remove hot air from the room or the intake mode to bring in cool fresh air from outside.
A window fan does not offer as much cooling as a window air conditioner.
What are the benefits of using a window fan?
Window fans have an advantage over other room fans. They not only help with air circulation, but their exhaust function helps remove stale air from inside your room. After that, the intake function helps to bring in cool air inside.
What is the best way to clean a window fan?
Window fans tend to collect dust on the grilles or the blades over time. To clean them, first, unplug the fan and use a vacuum to direct compressed air on the dusty parts. Use a brush to, well, dust the dust away.
If the fan is placed in a kitchen, it might also collect grease or grime over time. To clean, follow the same procedure as mentioned above. After that, take a mixture of dish soap and water and gently wipe the grease away. Make sure the fan is dry before plugging it in again.
Should the window fan be in the intake or exhaust mode?
Cooling a room using these two functions can be done in several ways. If the weather is cold outside, put the fan on the intake mode. This will blow cool air inside. On the other hand, if the weather is hot outside, place it on exhaust mode. The exhaust fan will expel the hot indoor air.
Do window fans let in bugs?
A window fan might let in bugs because it is essentially sucking air in. To avoid that, make sure your fan comes with a removable cover or seal. This will help with keeping the bugs out.
How do I troubleshoot common issues with my window fan?
Some common issues you might encounter while using a window fan are the fan being dirty or clogged, the fan not working, the remote not functioning, the fan making beeping sounds, etc. There are simple ways to solve these issues, and some might even overlap with window AC repairs.
Try unplugging and replugging the fan. If the remote isn’t functioning, change the batteries and try again. Check your fan’s settings to make sure it isn’t working in the wrong mode. Clean and unclog the fan using a vacuum and some dish soap. However, if none of these simple solutions work, contact the customer support team for further assistance.
Conclusion
After looking through all these fans, the best window fan on this list is the Genesis window fan. Being a twin-fan unit, it offers efficient air circulation and is easily portable. It also comes with removable feet, so you can easily convert the fan from a window fan to a desk/table fan.
If you’re in search of a fan that is trusted and reliable and does its job well, the Bionaire window fan is the best option. The Comfort Zone window fan is another good option, and it comes with a remote control as well.
Hopefully, that helped you make up your mind. But if you’re still in doubt, I insist on going through the options and buyer’s guide again to make the best decision for yourself.
