Buyers Guide

Placement of the fanHow much airflow you needPowerWind directionNoise
  • Depending on where you are going to place the fan, you can either choose between a dual or a single window fan. Dual windows are ideal for kitchens as one fan works to throw the exhaust and one will bring in the fresh air.
  • However, if you do not find this arrangement convenient enough, you can go for two single fans and place the inward blowing fan in a fresh and shady place so that it brings the cool and fresh air from outside.
  • This will entirely depend on the size of the room and if you are using any other appliances for cooling.
  • For a normal sized room, one exhaust fan and one inward bowing fan should be enough. However, you may have to consider the size of the fan. If the window frames are much larger than the fan size, you can make use of extenders to seal of the vacant space so as to ensure optimal efficiency.
  • To know how powerful a fan is, check its CFM rating or cubic feet per minute rating. This will determine how much air the fan can pull out and push into a room.
  • Remember that although a higher CFM would mean more powerful performance, powerful fans could be overbearing, especially if the room is smaller.
  • Even if a certain fan claims to have a high-velocity performance, be sure to check out the window fan reviews of the product before making the purchase.
  • If you are familiar with the wind direction around your house, it becomes easier to select the window fans for different areas around the house.
  • For e.g. if the outside wind direction assists the direction of the fan, you may not require it to be very powerful. You can also increase the efficiency of the fans by placing them over spots which receive constant bursts of cool air.
  • Some fans make a lot of noise while operating. This can be a huge distraction, especially if you need to use it on a constant basis. Therefore, look for models that do not produce a lot of noise.
  • The window fan reviews featured later in the section can guide you on which models produce the least noise.
  • Below are the detailed window fan reviews of 10 products which are considered to be the best in this category. Going through these window fan reviews will help you narrow down on the choices and make the selection process much quicker and easier.


These fans have been meticulously chosen in order to bring you the best out of the lot. All are window fans and can be fitted directly into the windows to recreate a soft breeze inside the house. In some models, you can reverse the direction of air flow with a simple touch of a button. Also, these are universal window fans meaning that they can be installed into the windows of all shapes and sizes and can go with different types of decor. However, from the 10 window fan reviews featured above it is quite clear that the best is the Avalon Twin Window fan.

This particular fan has many high-end features such as the Max Cool Technology and an adjustable thermostat which takes it a step further in-room cooling.
