This is why we’ve figured out that the best way to find the window fan is by opting for something sturdy with a friendly price tag. We’ve taken it upon ourselves to scour the web for user feedback and product information to learn about which window fans work best. Through hours of research, we’ve made sure to pick the ones that are not only reliable and effective in improving your home’s ventilation but also ones that you won’t mind having for just a couple of years. We can certainly promise that our picks are among the finest options in the market today.

THINGS TO CONSIDER BEFORE BUYING A WINDOW FAN

1. WHY DO YOU NEED A WINDOW FAN?

Do you live somewhere warm? Does your kitchen get too stuffy even with the windows open? Is a regular fan not enough to cool most of your rooms? If you answered yes to all of these questions, then you need a window fan because your home needs better ventilation.

Are you bothered with your electric bills shooting up every time you turn on the AC? If yes, you also need a window fan as it can effectively offer a cheaper alternative to running the air conditioning all day long. The best twin window fan can efficiently pull in cool air from the outside and then pull out the hot air in your home. While it doesn’t really do much for humidity, it can still help cool your home without spending so much on utility bills.

2. Is your home ideal for using window fan?

One of the most important things to know about window fans is that they may not exactly work the same way for every home. Some houses can get the best benefits from these appliances, while others might get the opposite of its intended effect.

Do you have windows that take a good amount of breeze? Is the outside temperature in your area cooler than indoor temperatures? Are your windows away from garbage piles and other things with foul odor? If you can answer yes to all of these, then your home can actually benefit from a window fan.

3. What type of fan do I want?

To know what kind of window fan you want and need for your home, you might first want to get to know your options. You can choose from single reversible fans or twin window fans.

The reversible fans come with a single blade that you can switch to either serve as an exhaust fan or to pull in cool air from the outside. The twin window fans, on the other hand, have two blades that you can set up to pull in cool air, push out hot air, or do both at the same time.

Twin window fans are heavily preferred by many because of its efficiency. By simultaneously pulling in cool air and pushing out hot air, it can definitely do more for your home’s cooling. As the two types aren’t that far apart in terms of prices, you might want to go for the twin type instead.

For homes with smaller windows, dedicated window fans can also be good cooling solutions. One fan can be set up to pull in cool air and another can be used to solely pull out hot air in stuffy rooms. It all really depends on the air circulation situation of your home, so make sure to weigh your options carefully.

4. Where am I going to place the window fan?

A lot of window fans are placed in kitchens as these rooms tend to heat up most often. The best dual window fans can work best in these areas.However, if you want to use single window fans in different areas, you can also do so. To get the best results, place the inward-blowing fan in a shady window. If it gets a good amount of breeze, the better option it is. It’s also best to place these fans on the ground floor of your home. Don’t put it near garbage bins or parking lots, though, as doing so will pull in bad odors as well. For outward-blowing fans, place them on sunny areas or upper floors.

5. How many window fan I need for better comfort?

This largely depends on how big your home is and the purpose of your window fan installation. In some homes, a single unit of dual window fans is already enough to cool the kitchen or bedroom. Some like to put one in each room as well. To know the best answer for this question, you should assess your home’s cooling needs.

6. What’s the Size of the fan?

The best thing about single and dual window fans is that they come in lots of different sizes. The best way to find the right match for your home is by measuring your windows to know which ones will fit. You can also opt for a smaller unit since there are extenders that will secure the fan into place. They also seal off the space in between the fan and your window frame, ensuring optimal airflow.

7. How powerful does the fan need to be?

As experts say, the more powerful the fan, the more effective it will be to pull in cool air and push out warm air. However, you should still assess the room’s needs as an overly powerful fan can be very overwhelming. To know just how powerful a window fan can be, look at its CFM (cubic feet per minute) rating. This will tell you how much air the fan can move.

8. What features do you want?

Do you want a window fan that can do more than just blow air? There are tons of different extra features various models offer. You might want to look for the more useful ones like remote control, variable fan speed, or even a thermostat among other things. Be careful of products with too many bells and whistles, though. They might not really offer better performance but only heavier price tags.

9. Does the window fan create noise?

Does white noise bother you? One of the drawbacks of fans is that they can create some noise while in operation. This is particularly true if it’s set in the highest fan setting. This shouldn’t be bothersome as long as they don’t exceed 60 decibels which is the same volume of a normal conversation. Considering that you won’t really always place your head right next to the fan, this volume can get lower and less noticeable even more.

BEST WINDOW FAN REVIEWS (OUR TOP 8 PICKS)

 Number #1: AirKing 9166 Whole House Window Fan

The Air King 9166F is the most expensive window fan on the list. That’s because it generates an impressive airflow. Paired with an industrial grade motor and 20” blades, it delivers a high velocity of air. With the blades rotating at 1600 RPMs and 170 watts of power, this unit cranks out 35 cubic feet of air per minute. 

For easy mounting, this model comes with adjustable metal plates. The panel extends from 27” to 38” inside window frames. Unlike standard models, the Air King 9166F mounts with a Storm Guard, which closes behind the unit. With the Storm Guard, you don’t have to worry about rain and pests entering inside. 

Beyond its impact-resistant plastic housing lie powder-coated steel blades. Air moves rapidly through multiple rooms. The unit has controls to operate the intake and exhaust features to low, medium, and high. With a reversible exhaust function, you can remove hot air from the house before turning on the fan. 

Even if you have an air conditioner, using the exhaust is extremely cost-effective. When you use the fan’s exhaust to get rid of the warm air, the AC doesn’t have to work as hard. In most cases, it only takes about 30 minutes to remove hot air from your home. Then, it takes about 15-20 minutes to cool the house down. 

On the downside, the noise can become distracting. The unit reaches up to 64 decibels when operating at high speeds. Still, user feedback is encouraging. Owners appreciate the fan’s ability to circulate fresh air through the entire home. Key features include a front-mount rotary control and easy installation. Plus, the unit is OSHA and ETL compliant and comes backed by a one-year limited warranty.

  • Perfect exhaust fan for vent hood while you are cooking.
  • It cools down the room effectively. It takes approximately 20 min to cool down room temperature to 6 degrees lower. 
  • Easy to install.

Cons

  • Due to the large size, it will block the view outside.
  • Can be noisy at high speed, but it might not need to be used as it is powerful and effective at low speed just as well.

The numbers are visible in the dark so you can read the temperature without getting out of bed. 

A bottom groove slides over the windowsill to guarantee accurate alignment. Modifiable side panels extend from 24 to 37 inches wide. Since the unit has two fans, you will need a double-hung or vertical-slide window for a proper fit. Casement windows require a set of brackets.

Compared to the other fans on the list, the Genesis Twin Window fan falls between the Holmes 2041 and 2021 models. Its powerful copper motor and 9” blades push air about 16 feet.

Its slim profile allows you to install it into windows without removing the screen. 
This model doesn’t have a thermostat to regulate temperature. Still, it delivers a pleasant breeze within minutes of turning it on. With a CFM rating of 320, the twin 6” blades can cool a room up to 500 square feet. 

Instead of three-speed adjustments, the fan comes with a sliding switch to change the setting from low to high. Furthermore, there is no control to activate the fans independently.
