What is a Window Fan?
The window fan is a cooling device that is designed to fit a window frame. Most of the fans have expandable panels intended to secure the appliance tightly in the frame. Using a window fan, you can have the temperature that you want and at the same time, breathe fresh purified air.
Typically window fans are very cheap. Moreover, using them, you can cut the money you pay for electricity bills. They are more budget-friendly than air-conditioners. They usually come with three-level speeds. Some window fans have only one fan; others have two fans. The one-fanned devices are designed to cool a single room. The two-fanned appliances are more powerful, and they can circulate the air of a whole house.
The top window fans are electrically reversible so that you can choose from exhaust or intake modes. If you prefer solid units, you should get the old window fans because they are made of metal and are heavier than the new ones. The modern window fans are made of plastic.
The finest window fans feature a thermostat and a grill. Thanks to the thermostat, the fan gets turned off when the desired temperature in the room is reached. The grill changes the direction of the flowing air.
Some more advanced window fans come with remote control and a special timer. The remote control makes the fan easy to operate with. The timer is connected to an automated shut-down option.
Window fans are more effective than box fans. The window ones bring in fresh air from outside and take out the stale air. Box fans can only circulate the inside air. Window fans are also better than air conditioners in terms of being more eco-friendly. Window fans can decrease the temperature in a room with around 20 degrees Fahrenheit.

Who Needs a Window Fan?
Today, there are so many products at the market intended to make your life better, that one starts wondering, ‘Do I really need this?’. The same thing goes with window fans. Before you choose to spend your money on one or more fans, it is a good idea to decide whether you need this product or not.
To help you find out the answer to this question, we have selected the top reasons someone may have to purchase a window fan. Read them and see if you are one of those people.
You can’t bear the hot temperature during the summer. Your only escape is your home. Unfortunately, the air inside it is even warmer than outside. This sign is the first one that you need a window fan.
You have found an effective way to run away from the heat during the summer – an air-conditioner. It is an indisputable fact that it does help to make the air at home colder. However, you have to pay high electricity bills. Here comes the window fan, which is a much cheaper option than the air conditioner.
You live in a place where the air is not only hot during the summer but also dry. Then you should consider getting a window fan in combination with an evaporative cooler. These two devices will circulate and moisturize the air inside your house.
You live in a several-floor house, and it seems impossible to keep all of it cold during the hot summer days. Worry no more! You can solve this issue using two or more window fans. Situate an inward-blowing fan on the ground floor and an outward-blowing one on the top floor.
Turn them on during the night when the temperature outside is lower than inside. The inward-blowing fan will bring in cold air from outside. The outward-blowing one will take the warm air outside.
Your area is a warm but moist place. This factor creates permanent mold in the corners of the rooms of your house. Then you definitely need a window fan which to circulate the air all the time.
You want to refresh the air in the attic since the effect of the air conditioner doesn’t reach that far. Then you can place an outward-blowing fan in the attic.
If you are concerned about the health of your family and yourself, then you also need to think about what you breathe at home. Recent researches show that our modern houses nowadays are more prone to store toxic particles in the air because of their tight constructions. It is proven that the air inside is more toxic than the outside air.
So you need a window fan to bring in fresh air from outside and take out the toxic particles that circulate inside. These devices do help a lot to improve air quality.
Note that you can combine window fans and evaporative coolers to make the air at home cold, fresh, and moistured.

The types of window fans differ according to the number of blades that they have. There are single and twin fans.
Single fans have only one set of blades. These fans are smaller than the twin ones. They are the most suitable ones if you have regular windows. Their installation is easy. That’s why they come with a kit that you can use to install them by yourself.
As their name suggests, twin window fans have two sets of blades. They are larger than single fans. Thanks to their size, they can move a larger quantity of air than the single ones.

How to Use Window Fans for Home Cooling
The efficiency of your fan depends on the way it is being used. So we have prepared some tips on how to use window fans for home cooling.
The right shape is the square one. If you wonder what the form of your fan should be, we are here to tell you. The top fans are the square ones. The air that they blow goes only in one direction.
This is what you need if you desire your fan to bring cold air in and suck warm air out of your house. The rotating fans are efficient when it comes to circulating air inside, but they are not good in terms of bringing air from outside.
Another advantage of square fans is that they are less expensive than the other ones.
If you have already chosen your window fan, you should make sure that your windows have bug screens. Without such nets, you run the risk of having unwanted guests like insects or even small animals.
Let’s say you have the right fan, and you have chosen the most appropriate window in terms of screens. Now, another thing you should take into consideration is the noise factor.
If the fan is near an outside area that is too noisy, you should be warned that you are going to hear the sounds even louder through the open window. Moreover, it is going to be even noisier because of the sounds that the fan produces.
If you have the chance, situate the window fan near trees or flowers, which can bring some pleasant smells in your home through the fan.
It is a better idea to turn the fans off during the day. In case you decide to leave them on at day time, then you’d better set at least two devices to blow inwards from the shady part of your house.
If you live in a house with more than one floors, put the outward-blowing fans on the top floor, preferably the attic. This act will ensure that the device sends the warm air out.
Nobody wants their window fan to fall in their house or even worse – outside. To avoid this, make sure that you secure the fan tightly between the window and the windowsill.
It is advisable to remove the fans when it is hot outside. If you find it challenging to take the devices down, then you can put a wet towel over the inward-blowing fans. The towel should be as big as the fan will be placed over. This technique will improve the cooling power of the device. When the hot air goes through the wet towel, its temperature will get lower.
How to Clean Your Window Fans
Another thing you should be familiar with if you want to enjoy the fresh air at home is how to clean window fans. In this part of the article, we want to show you some useful tips that will help you keep your cooling devices clean.
- Firstly, you have to unplug the window fan. It would be very dangerous if you cleaned the cooling device while it was still plugged in. Make sure that you put the fan on a hard surface before you start the cleaning process.
- Remove the grill of the fan. Some of them have screws, so you need to use a screwdriver to unscrew them. Release buttons secure other grills. If this is your case, then you should press the button. To clean the grill, you need to use a vacuum cleaner
- Another thing you should do is to clean the blades of the fan. You can do this with a piece of cloth. Put it in a soap solution. It is essential to keep the water away from the inner unit of the fan.
- You should dry the blades of the fan before you turn it on.
- Turn the fan on to enjoy the cold air.
The Do’s and Don’ts of Window Fans
If you want to keep the air in your house cool and fresh for less money than if you use an air-conditioner, you should know how to use window fans wisely. We have provided a list of the dos and don’ts of window fans, which you should have in mind if you want to enjoy fresh summer days at home.
Do’s of Window Fans
The More, the Better
It is needless to say that the more window fans you have, the colder the air they will make. It is useful if you can ensure that you have an equal amount of window fans that blow in and such that blowout.
Put the in-blowing fans on the shady part of your house, and the out-blowing ones – on the sunny part. If you are lucky to have a several-floor home, then you should position the inward-blowing fans on the first floor and the outward-blowing fans – on the other levels.
The Bigger, the Better
If you are granted the opportunity to choose the size of your window fan, then you should always prefer bigger window fans. Of course, you should make sure that the device you buy fits your window. More massive fans can circulate a larger quantity of air. However, the fans shouldn’t be larger than the window because when you place them outside the window frame, they are going to fall.
It will be great if you can block with something the space that is left on each side of the fan. If your budget allows, you can get a fan that comes with a uniquely designed seal that will cover these cavities. If you don’t want to worry about blocking holes, then you can get a narrow window fan that will suit your window perfectly well.
An Energy-Saving Mode
If you want to save energy and money at the same time, do the following. In the evening, make the window fans on the ground floor blow cold air in, while the fans on the other levels blow the warm air out.
In the morning, turn the fans off and close the windows. If you have insulated well your house, it will manage to keep the air in the house cool all day long. When the evening comes again, turn the cooling devices on and open the windows.
Don’ts of Window Fans
You should carefully pick where to situate your window fan. Try to locate it away from any sources of unpleasant odors like bins, parking lots, or commercial buildings. This way, your fan won’t bring unwelcome odors inside your house.
If you are a fan of musical instruments or antiques and you possess such things, you should be extremely careful where you choose to install your fan. Keep in mind that if you use fans, the temperature can vary from very low to very high. These fluctuations can damage musical instruments or antiques. So try to situate the cooling devices in the furthest possible room.
