That was our round-up of the 11 best window fans. In the next section, we will look at how window fans work and why you need one.

How Does A Window Fan Work?

A window fan functions in either of the following ways

  • Pulls in the cold air from outside
  • Pushes out the stuffy/hot air from the room

The main function is decided by the positioning of the window box fan. You can combine the two functions if you install one fan for pulling in the cold air and the other for pushing the hot air out of the room. Some fans offer reversibility, and you can just switch between the intake and exhaust modes.

Why Do You Need A Window Fan?

When compared to air conditioners, window fans are more economical and an energy-saving way to cool your house. While they are often used as a supplementation to air conditioners, if used properly, they might replace them altogether. If you are looking to save energy and money while staying cool sitting inside your room, go for a window box fan.

There are three different kinds of window fans available online, and each of them comes with their set of functionalities.

What Are The Different Types Of Window Fans?

1. Single Unit

A single unit comes with only one large fan that is approximately 24 inches in diameter. It is ideal for cooling the entire house. Since it has a high CFM rating, it might get loud at a high setting.

2. Double Fan Unit

A double window fan is the most popular choice amongst all the types. It houses two fans, ranging from 6 to 10 inches in diameter. It is ideal for medium-sized rooms. It has a moderate CFM rating and does not produce a loud noise. It is versatile and fits sliding, casement, or double-hung windows.

3. Triple Fan Unit

This unit features three fans with a diameter ranging from 4 to 7 inches. They are small, have a high CFM rating, and ideal for studio apartments or dorm rooms. However, it is difficult to know how efficient they are with high volume airflow.

Now, that you are aware of the three basic types of window fans, let’s us talk about the things that you need to look for to choose the perfect window box fan that suits your home and living arrangements. Here are a few things to consider before buying a window fan.

What Are The Things To Consider Before Buying A Window Fan?

1. Reversibility

Most window fans come with an easy reverse method to draw air inside or function like an exhaust. Some use an electronically-reversible fan motor where you change the mode at the push of a button. Others require you to turn them around manually by removing the fans from your window. It is better to spend a little more and get an electronically-reversible window fan.

2. Noise Level

You would not want a fan that gives you a headache due to its loud noise. Therefore, make sure to check its sound level. Usually, the single unit fans are louder than the others.

3. Speed Settings

The more options you have for the fan speed settings, the better. Most window fans come with three speed settings.

4. Warranty

A manufacturer’s warranty gives you an idea of how long the product will last. Most window fans have a warranty that lasts around 1 to 5 years. In case the fan stops working during the warranty period, it can be argued as a defect in the parts and quality. Thus, check how the warranty works and the process of claiming service.

5. Controls

When it comes to the controls of a window fan, see if it can be easily operated. Remote control makes the operation easy and comfortable. For a slider switch, check the ease of use in switching the speed settings. If it is a dial selector, see how tight it is or how quickly the push-buttons respond.

7. Material

Consider going for a window fan that includes as little plastic as possible. Opt for one that has a metal housing. Weather-proof motors ensure that your fans stay safe from any electrical shocks during rains. This can be indicated by its damp rating.

A window box fan enhances the air quality inside your house and keeps it cool. Thus, investing in a window box fan is a great decision. Pick a suitable one from our list of products and enjoy quality air indoors.

Expert’s Answers For Readers’ Questions

Should a window fan be on intake or exhaust?

Since most window fans have both intake and exhaust options,  use the reversibility mechanism to change it as per your requirement. For example, an exhaust option works great for the kitchen while the intake option is best suited during sleeping to draw in the cool night air.

Do window fans use a lot of electricity?

No. Window fans use lesser power than air conditioners. Most windows fans consume 35 to 100 watts, depending on the brand and model.

Is it cheaper to use a box fan or AC?

Fans are definitely cheaper than air conditioners. You can either use them instead of ACs or even alongside them to save money.

How to use window fans for home cooling?

For using window fans as a cooling unit, bring the outdoor, fresh air inside your home when the air outside is cooler than inside. Once the inside air gets cool enough to cancel out the daytime temperature, turn off the unit,  and close the windows.

Are window fans safe in the rain?

All window fans come with an enclosed motor that can be used safely in rains. However, it is advised to remove the unit from the window during a heavy downpour to avoid the powerful winds blowing water into your house.
