Frequently Asked Questions (FAQ)

What is the best window fan to buy?

Window fans are a popular alternative to air conditioners. They are effective and energy efficient, but you need to be careful what kind you buy. Setting up a fan is easy. The hardest part is deciding which fan to buy.

Where you place the unit is also important. Yes, you could place it in an open window, but the best location is a frame-less window. If the window is frame-less, there aren’t any rails to get in the way. The best location is at the bottom of the window.

There are also different sizes and styles of window fans to choose from. The two main styles are belt and box fans. The box fans are more expensive and heavier, but they also provide better air distribution.

Are Window fans better?

Or, are Tower fans better?

Window fans are great for two reasons: they push an incredible amount of air out %u2013 and they are more energy efficient than most tower fans. These two important functions are where tower fans fall flat. The thin blades of the tower fan are simply not balanced to provide a strong push. That said, window fans don’t blow as far as tower fans.

What is the best box fan?

The main thing you want to look for in a box fan is that it has at least three speeds. Other than that, you want to look at how many blades the fan has. Three or more blades will do a much better job at spreading the air around the room.

You will also want to look at the construction of the fan. Most of them are metal, and they are fairly sturdy. Many of them are also reversible, which helps you save some money and time on having to buy larger fans later on.

Some box fans are also made of plastic, and these are much less durable. They tend to break during normal use, and they can be a safety hazard. You will want to skip these fans and go for the metal ones.

Which type of fan is best?

When comparing Window Fans, you will see there are four different types: Casement, Industrial, Exhaust, Cased.

The Casement is the most popular out of the four because of it's convenient size, exhaust control, and it's energy efficiency. The Exhaust fan is most commonly used by restaurant owners because it's 8 inch diameter can provide the most air flow in a limited footprint. The Cased fan is used most in commercial settings such as factories because of their strong construction and capacity to hang off a beam. The last fan is the Industrial fan, and has been used for years in water treatment plants, as well as, areas where extremely high pressure and air flow are required.


If you are interested in cooling down your home without spending a fortune, then window fans can provide a lot of relief. However, the best window fan can differ from person to person, depending on their needs. It is important to examine the things you will look for in a window fan before making a purchase.
