Buying Tips for Small Window Fans

Updated on September 27, 2011

Stay Cool With Small Window Fans

Small window fans can help keep an individual room cool. Many of them can even act as an exhaust fan to remove stale or warm air from your space. These fans will not cool an entire house but they are perfect for smaller spaces. They are also economical and help keep your total electric bill down.

On this page you can see a variety of well regarded small window fans to consider.

Choosing the Right Fan

When you choose one of these fans you want to be sure to consider the size of the window where you want to place it. You can compare this to the fan's measurements. Many of them offer built-in extender screens and additional extenders to assure a good fit in a range of windows.

You'll also want to look at the ability of the fan to cool the room. More Watts means more power. Dual blades often move more air than single blades.

Plastic blades tend to be quieter but metal is less likely to break.

Small window fans with a thermostat can help you regulate room temperature better, but a timer can also help keep temperatures acceptable when you will be sleeping. Remote controls can add convenience.

Locks and so forth can be a good idea for safety and security.

If you want to use the fan to help remove smoke, odors, or excessive warm air in a room, then reversible fans are a good idea to allow it to be used as an exhaust. Some of these fans allow you to have each one of two fans operate independently, allowing it to perform both functions at once. Electrical control versus manual control of this function makes adjustment easier.
