Best Window Fan

Looking for the best window fan? Below is a guide to help you in making informed buying decision.

What is a Window Fan?

A window fan, as the name suggests, is a fan designed to be positioned in the window. However, it has functions that make it unique from the other types of fans. Most fans, such as ceiling fans and tower fans, provide a cooling effect from the flow of moving air.

The window fan does the same – cools a room or any part of the house – but it performs this task by pulling in cool air or driving out hot air from the home.

Uses of a Window Fan

Aside from drawing in fresh air from the outside and drawing out warm air inside, window fans have many uses:

  • A window fan is a space saver – unlike the traditional table or stand fan, which takes up space in the living room or in your bedroom, making you a bit uncomfortable moving from one part of the room to another.
  • As it draws in fresh air from the outside, it allows the circulation of pollution-free air around the home.
  • It reduces your dependence on air conditioner and significantly lowers energy cost every month.
  • It is ideal for kitchen, laundry and basement areas, and bedrooms, especially the small ones, as it cools the area at night, providing the occupant a good night sleep.
  • It costs less than air conditioning unit.
  • It eliminates unwanted odors inside the house; these usually emerge when there’s so much cooking happening in the kitchen or when a household member is a smoker.

Energy Efficiency Compared to a Ceiling Fan

When looking for the best window fan to buy, you must not only think about the brand or model that promises durability; you must also consider energy efficiency. This fan expends a small amount of energy, while still providing efficient cooling in various types of weather.

Savegreenly made a study on the energy use of window fan and ceiling fan. It found out in its research that a ceiling fan uses around 60 watts to more than 200 watts, depending on the model. When it tested the window fan using the power meter, it recorded 61 watts – already set on high, 52 watts on medium, and 48 watts on low. The website added that window fans already provide households with good amount of air flow on these wattages.

Do’s and Don’ts about Window Fan Placement

The best window fan helps increase and improves the circulation of air inside your home, and reduces your dependence on air conditioning – if you know where to place it strategically. Here are a few tips:


  • Position the fan that’s blowing inward in the same direction as the blow of the wind and on the coolest area of the home.
  • Use an equal number of window fans to promote cross-ventilation. For instance, if you want one fan for the first floor, you must also install one across it. The first fan should blow inward and the other one outward. Make sure that doors between them should be opened to maximize air flow.
  • Locate the fan on the upper level of the multi-floor homes and open the windows on the lower level. If this is not possible, place separate fans on each floor.
  • Improve the ventilation of every room by placing a window fan blowing inward. These fans will also work together in pulling the air throughout the house (but this still depends on the layout of your house).


  • Avoid placing the inward blowing fan close to the garage, garbage can, and other areas that will let unpleasant odors and toxic fumes to go inside the home. You can consider positioning it somewhere near trees to make the inward air smell pleasant (unless pollen poses risks).
  • Never position it toward a freezer or fridge as this may cause air to cool down faster than the usual thereby increasing the electricity load on the appliance.
  • Do not place desks (antique or not) or expensive carpet below the inward blowing fan to avoid water damage.

Buying Guide

To get more value for your money and to maximize the use of the appliance, you must make sure that you will purchase the best window fan available in the market. Below are some tips on the factors to look for when buying the best window fan for cooling:

Durability, Safety, and Appearance

Check the construction of the window fan you are interested in buying. Are the materials used solid? It will also be practical if you check its repair history. You may also read reviews online. On the contrary, blades should be made of soft materials or at least confined in a grate for the safety of everyone – particularly the children.

The look is also a factor to consider, particularly if you will place it in your well-designed living room, to match the lavishness or the exquisiteness that you may want to portray.

Wind Direction

Place the fan that you bought to the window that faces the prevailing wind or farther from it to promote cross-ventilation. However, if your home is located in the region where the direction of the wind changes often, you should buy the reversible-type window fan. It can pull the air into or out of the house, depending on the wind direction.

Ease of Use

Remote controls and timers are among the standards in appliances today. You may already think that these will be enough to make your use of the fans easier, but you must make an effort to still check how they are operated and confirm if they are easy to control so the other members of the family can use without any trouble. The appliance should also be easy to clean.


The airflow volume of the most powerful window fan should be enough to cool down the size of your room or an area in your home. Likewise, consider the noise level. Is it quiet enough to let you sleep and hear what is happening in the different areas of the home?
