This company has produced a handful of climate control devices allowing users to have a comfortable and healthy home environment. This one belongs to the best of them. The first thing that attracted me about it is its compact size.

It even looks stunning, thanks to the designers’ hard work. They have reduced the size of the blades and increased the number of fans. In total, there are three fans in it.

In terms of efficiency, this one is a powerful machine. The fan fits best into windows having a size of 25.5 inches. Its expandable screens let it fit perfectly in most of the windows. Also, they allow the users to position the fan both vertically and horizontally.

The fans have a size of 6 inches each, and they contain nine blades that are twisted. They are designed in a way so that you can adjust the airflow however you want.

When it comes to ventilation, our guy might be a bit short on capacity than other units out there. Nevertheless, considering its size, it serves the purpose well.

Moreover, the fan comes with reversible airflow. But you will have to turn and reinstall it manually for that since the blades are capable of rotating in only one direction. You might be surprised at how the simplest of devices survive the longest of periods, and this thing is one of those.

  • Astonishingly durable


  • To switch between exhaust and intake modes, you have to manually turn and reinstall the fan

The manufacturers have made this product mainly for commercial uses. Be it a restaurant kitchen or a workshop; this thing will do the job perfectly. You will be impressed at the fan’s ventilation capacity. It even ventilates huge rooms effectively and quickly. So, you can guess how fast it will ventilate the small rooms.

Sadly, there’s an issue with the model. Its motor isn’t that quiet when you select the highest speed. To avoid this hullabaloo, you will have to set the speed lower. During night time, the low-speed setting does the job nicely though.

The fan is easy to install as well as convenient. It fits the windows having a size of 27”-38”. The shipping package contains everything you need to install it.

In exchanging the room’s damp air with the outside fresh air, the fan works efficiently. And the speed settings offer you comfortable airflow in all seasons.

On a hot summer day, you will want to use a high setting. For ventilation in an autumn evening, the medium speed is always the best. And when you feel like you have enough natural breezes getting inside your house, you can set the speed to low.

Your Definitive Buying Guide to the Right Window Fan

Before buying a window fan, you need to look into some details so that you can make a smart purchase. Here are a few factors you need to keep in mind.


Usage and Type

Window fans basically are of three types: exhaust, intake, and reversible. Let’s see what they are about;

  • Exhaust Fans

These fans are used to remove polluted, unclean, and stale air from inside the building. Mostly they are used in kitchens, bathrooms, workshops, etc.

  • Intake Fans

They bring fresh air into the room. There is no exhaust system included in these fans. Other than taking in the fresh air, they increase the air pressure slightly inside the room. For ensuring efficient ventilation, these fans are perfect.

  • Reversible Fans

These are the best among all three types of fans. They serve both as an exhaust and intake fan.

Now, think about what type of fan you need considering the premises you want to ventilate.


This is one of the things that you look for first. It is only natural that the more powerful machines will move the air more, providing better ventilation. The power of the motor controls the airflow.

The amount of air to be moved is the key factor that works in the minds of manufacturers. Lots of effort is put on making the machine powerful so that it allows the fan to ventilate properly.

They measure it in cubic feet per minute (CFM). You might be wondering, what’s the big deal about this. Well, it plays an important role in estimating the amount of space the fan is capable of handling.

So, by looking at CFM, you can decide whether you want a particular fan or not. Usually, a fan having 160 CFM ventilates a 1000 cubic feet area.


The last but certainly not the least factor to keep an eye on is the convenience the fan offers. It is only expected for a machine’s motor to make a bit of noise. Needless to say, how annoying it is to sleep with noisy stuff around. Therefore, make sure to check on this issue before you go for a device.

Then again, there are products that are noisy, yet they deliver excellent performance. So, you need to set your priority first. If you cannot stand the slightest of sounds, then go for the units that are quiet in their operation.

A fan producing 65 dB or less will be just fine for you. These types of fans are quiet and very comfortable.

Another crucial thing to keep in mind is the design of the model. The fan you are purchasing should fit into the window opening of your room.

There are some fans that come with a feature known as “French blinds.” What they do is that they prevent the cold air from getting into the room. Get one of these fans if you can.
