We have put together a top 10 list of these by actual buyer ratings. We have also included a full buying guide, which we recommend that you read first, before buying a fan for your home.

We would like to point out that not all rooms or homes will benefit from a window fan. Any window that is sheltered from the wind is completely useless for attaching a window fan to. There needs to be some type of wind blowing against a window, for the fan to be properly effective.

Window Fan Buying Guide

The principle behind a window fan is pretty simple. They work in either one of two ways:

  1. They either pull in cold air from the outside to the inside of your home or,
  2. Draw hot air out of a room and push it to the outside

The pull or push method, as they are more commonly known is decided by whichever way the fan is actually facing. If you have for example two windows in a room, you can create a great effect, and a nice cooling breeze, by having one pulling the air in, and the other pushing it out.

These type of fans work best in windows that face a prevailing wind. A prevailing wind is simply the wind that blows predominantly or mainly in a certain direction.

A sheltered window for example, would be useless to place a window fan in, as ideally any window selected, should have some form of wind blowing against that window.

Why Use a Window Fan?

The main reason people go for one of these is that is a heck of a lot cheaper than either installing or constantly running air conditioning. Window fans are an economical and energy-wise way to cool your home, and help keep it feeling fresh and clean.

Wise and thrifty home owners may also use these to supplement air conditioners. If you can get their placement correct, you can actually do away with expensive air conditioning. The key is though to understand how and where to place these to get the maximum benefit.

Where Should Window Fans be Placed?

The best way to think of this is that typically most people will simply open a window to allow some fresh air into a room. It is nice to have a clean and fresh room. Sometimes though that just isn't enough.

That is when placing a fan on your window sill can help draw the cooler air in from outside, and push it in to your house. It is a great idea as long as you don't live close to a fish market of course. It is important to understand the type of air and smells that sit outside your window.

For example on a busy street, there may be a lot of car exhaust fumes, and almost always you would be advised to keep your windows closed. Window fans are useless in these types of environments.

The ideal placement for a window fan is to have these on the cool side of your house. That is usually the side of your house where the shade is for most of the day. If they face out to a flower garden this can draw in a pleasant aroma, as long as no-one suffers from hay fever of course. 

Single storey homes work best if you have the inward fans on one side, and the outward fans on the other side. Don't forget to leave some doors open to allow the air to flow through.

Which Size Fan Should You Buy?

To make them as efficient as possible, each one that you buy should be the biggest size available for that window. We would also recommend that you consider the noise level they make, and how much electricity they use as well.

Do Window Fans Really Work?

The reality is that window fans never really get fantastic reviews. In our business we have seen a lot of these being used over the years. In all honesty, most of them are used incorrectly.

The best way of using these is to use them at night to bring the cool air inside, and during the day to push hot air outside. To achieve that you need a balance between the fans pushing air out and fans bringing air in.

We mentioned the fish market and air pollution earlier, but even around the home there are windows that you should avoid. If you plan on drawing air in from the outside, then a window that faces out on to a garbage area, a garage or car port, or anywhere smells or fumes should be avoided.

In addition, if the air at night time where you live is just too hot or humid, or you suffer from pollution then don't waste your money on these as they will just not work. Never leave you window fans on during a rainstorm, as this can lead to serious water damage, and potential electrical damage as well.

Installing a Window Fan

Installing these can get a little tricky, though they are not impossible to do by yourself. You do however need to know exactly how to install these for them to work effectively. If in doubt it is really worth paying an expert to get this done properly.

As we have mentioned make sure that you buy the right size of fan that will suit the room that you want to cool.

You will also need to measure the window and look for the fan that offers the best fit. Take the inner measurements of the window as that is where it will be fitted. You also need to consider the wind direction outside of your home.

Remember these fans will either expel air out of your home, and/or draw air in from outside.
