BUYER GUIDE

Before you purchase a window fan, there are a few things that you should pay attention to in order to determine the quality of the product. Here is what you should bear in mind:

What to Consider When Buying Window Fans?

  • Noise

You’re looking for the quietest window fan, which means that you should pay special attention to how much noise a fan produces.

This is especially important considering the window fan will most likely run for many hours in a single day. Luckily, newer window fan models tend to generate less noise, and this is the case even on the highest speed settings.

  • Fan Type

There are two major categories when it comes to window fans: intake and exhaust. Exhaust fans send unwanted room air outside, and intake fans take cold air from the outside and pull it into your room.

You have to choose the fan that is most suitable for your needs. Luckily, it is also possible to choose a fan that has both features available.

  • Fan Size

The size of your fan is also important since you want to fit it on your window. If the fan is too small, the air will still circulate back and forth normally, while a big fan may be risky and adds extra costs.

  • Price

Prices for window fans vary, with the best window fans usually being the most expensive options. Fortunately, you can also find quiet window fans for smaller prices if you don’t have a high budget.

Make sure to do your research and choose depending on how much you are able to spend on the product.

  • Ease of Use

Whether you want a fan with 3-speed settings or a simpler one, you should always look for something easy to use.

The fan should come with different features that make it easy to operate. Some of these features could be a remote control and different speed levels.

You might also want a dual-blade product for more efficiency. Make sure the fan is also easy to clean and maintain.

  • Power

The quietest window fans can still be powerful, so you should make sure you look for an efficient item that can both send stale air out of your room and bring fresh, cool air in.

Choose a unit that has enough power, as it will help it perform better as well.

  • Safety

Especially if you have children and pets, you should consider a fan that is safe to have around. Pick a device with softer blades, and if possible, something with blades that aren’t exposed.

It will also prevent insects or other small beings from getting into your home if it has a screen.

How Does a Window Fan Work?

Window fans are a bit different compared to other fan types. They are there to get rid of stale air from your home by expelling it outside and bringing cool air inside from outdoors to refresh the house.

These functions can be found separately, but it is also possible to find window fans incorporating both of these features.

So, all you have to do in such a case is switch the function of the window fan by changing the direction of the blades’ rotation.

If you buy two separate fans, you can place them on separate windows to achieve the same result. One will be able to let hot air out, while the other will bring cold and fresh air in.

Advantages of Having a Quiet Window Fan

The quietest window fans come with several advantages as follows:

  • They Are a Better Option than AC Systems

If you don’t want to spend money on an AC system, you can simply purchase a window fan. It is more affordable, and it does the job if you install it in a small room.

  • Lower Energy Bills

While AC utility bills can be painfully high during the summer, window fans will help you reduce those bills.

  • You’ll Get Fresh Air.

If you don’t bring fresh air in, it will quickly get stale and unbreathable. By installing a window fan, you will allow it to circulate air and remove odors.

FAQ

Should a window fan be on intake or exhaust?

You should set your window fan on intake if you want to bring in some cool air and get some breeze. But if all you want is to remove stale air and odors, you should consider an exhaust fan instead.

How do you cool a room with a window fan?

Open your window and install the unit on the window you want the breeze to come in. When it cools off and the sun goes down, you should allow the unit to run and bring cold air.

Make sure the sash is closed, so the fan is stable. The fans should blow in at high speed too.

Conclusion

When looking for the best window fan, make sure you have your window measurements so you can pick the right size.

Not all the quietest window fans come with an extender panel, and you don’t want to choose a fan that doesn’t fit into your windows.

You may also want to consider if the fan is reversible or not. With a reversible fan, all you have to do is use a switch, and it will either bring in fresh air from the outside or exhaust stale air.

On the other hand, non-reversible fans will require you to change the motors manually. So you should really consider a lot of features, but make sure you choose what you need.

Quiet window fans with extra features are a little bit expensive, so think about your budget as well.
