Check Out The 7 Best Window Box Fans

It is nearly summertime, and you need something to keep you cool on those hot days. Unfortunately, while a cooling fan does blow pleasant air at you, it does not actually bring the temperature down. 

But with a window box fan, you can successfully do that. However, it only works if the temperature outside is lower than inside. So they can be most effective early in the morning or late at night. 

Window fans pump the hot air out while replacing it with cold air from outside. That is why if it is colder outside, the temperature of your room will also decrease. 

It also doubles as an exhaust or a chimney. You can either flip it around and use it to blow hot air out, or use a set of twin fans to bring in cold air simultaneously.

Why Choose Cooling Fans?

Why Choose Cooling Fans

An air conditioner can cool the whole room in a few minutes. So then why opt for a window box fan? The following reasons why:

  • Air conditioners are expensive and run on a lot of energy. And in addition to you paying a big fat electricity bill, it is also harmful to the environment.
  • You cannot change the position of the AC often. But, window fans are portable and take up much less space in the room than ACs.
  • It is healthier to sit in the natural air blown by the fans rather than in the cold air mechanically generated by the fan. 
  • Fans are the first choice for environmentally-conscious people because they are energy-efficient and cost-effective. 

Factors to Consider:

Before we start enlisting the best box fans for windows, there are many features that you might want in the set of your choice. So here’s a buyer’s guide that will help you through the process!

  1. Adjustable Speed

Speed is equivalent to the power of the fan. If you use the fan at its highest speed level, the motor is at its most potent. It will yield higher CFM, and you will feel the air hit you even from 15-20 feet away.

Multiple speed levels also give you control over the temperature in the room. 

  1. Reversible Airflow

All fans are reversible, i.e., able to push hot air out and pull fresh air in, but you have to flip them manually. However, many fans are electronically reversible, and all it takes is the push of a button. 

So, instead of reinstalling the fan, you can reverse the airflow electrically, hassle-free.

  1. Number of Fans

There is always the classic fan, which is only one fan that can be electronically or manually reversible. Then there are sets with two fans, and each one has one function.

One of them does the job of exhaust, and the other one intakes fresh air. So there is a simultaneous function that cools the room faster. 

  1. Noise Level

It is usual for devices to make noises or even vibrate at their highest speeds. But it is okay as long as it does not get too loud. If the noise is too much, then it can be a nuisance. 

So it is recommended to get a fan with minimal sound. That way, you can keep it on through the night without disturbing your sleep.

  1. Smart Controls

Don’t you hate it when you have to get up from the comfort of your bed just to change a setting on the fan? Thank the geniuses for the invention of the remote control. It makes things very convenient. 

You can access all the features of the fan without having to get up repeatedly with a remote. 

  1. Easy To Clean

When something is in use for a long time, it is bound to accumulate dirt and grime. For example, when fans intake air from outside, it also brings dirt. Cleaning them can be especially tricky because reaching the blades is difficult.

But many fans come with a removable grill, which makes it easy to wipe the blades clean. 

  1. Expandable Screen

The fan of your choice does not need to fit the frame of your window. That is why window box fans have expandable screens on all sides to cover the whole window and not leave any space.

But even with expandable screens, make sure to check the maximum dimensions of the fan.
