Window Fan Buying Guide
What may be the best window fan for someone might not mean the same to you. This is why the market presents numerous options for most products – window fans included. As you navigate your way through finding the perfect product, we advise you to consider the following guidelines. We think that the upcoming tips will make the shopping process easier and less stressful.
Top 4 Things To Consider Before Buying A Window Fan
- Window Fit
Categorically, the fit should be on your list of priorities. There’s no use to invest in a unit that won’t fit exactly on your type of window. Many buyers are tempted to factor in other state-of-the-art features such as automated thermostats, electronic reversibility, so on and so forth while overlooking this tiny detail.
That is to say, if you select a fan that is too large for your window, then it is likely to fall and break. Obviously, you don’t want that. On the other hand, picking out a fan that is too narrow or short and installing it in a large window won’t work either.
In fact, it will make it nearly impossible to remove it, granted that you want to change its location, or you want to remove it because you’re leaving on vacation for an extended period.
We’re not saying that your measurements should be expressly precise. As you’ve seen in our reviews, the majority of the products we present come with extenders. You can utilize those extenders for a customized, decent fit.
At the same time, the reason why most manufacturers feature extenders is to ensure that they keep bugs and other insects out. Moving on, some of the units on the market incorporate detachable legs so that you can easily transform them into standalone fans. This is a nice characteristic; you should establish whether that’s important to you or not.
- Type of Window Fan
Moving on, perhaps the second most important consideration is the type of window fan you purchase. In this view, we could divide window fans into two major categories – expressly intake and exhaust window fans. How do they work, though? And what are the main distinctions between the two?
When it comes to intake fans, such a unit works according to a principle of pulling cold air from the outside, while the exhaust type pushes out the stale air from the inside of the house. Considering that you want to optimize the performance of your window fan operations, then we advise you to factor in this characteristic.
Nevertheless, there are other considerations worth outlining. For instance, always factor in the intended placement of the unit. Considering that you plan on installing the unit on the sunny side of your house, perhaps it would be a good idea to get the exhaust type of fan, and vice versa.
Still, as you’ve seen in our reviews, there are fans that incorporate both functions. This is convenient as they combine the benefits of both types of units.
Another thing that should be present on your agenda is reversibility. To that end, the function of exhaust is linked to how fast a window fan can eliminate unwanted odors such as cigarette smoke, odors from burnt food, pet odors, not to mention that the stale air will also be refreshed.
As a rule of thumb, most window fans are capable of circulating and cooling the room inside the house at the same time; thus, they fulfill two important functions. Nevertheless, what if you intend to change the directions of exhaust and cooling?
Unfortunately, at times, the window fan has to be removed from the window to be flipped around. We’re referring to manual reversibility. Of course, this may be a tad inconvenient. On the other hand, there is the option of electronic reversibility, which is much more convenient. That is to say, it facilitates this switch with the push of a button.
So, in this respect, in case the temperature outside changes unexpectedly, what you have to do is reverse the fan. It’s as simple as that.
- Safety and Durability
We could say that safety and durability and key characteristics that should be considered whenever you’re shopping for an important appliance. To that end, granted that you want to invest in an evaporative cooler, or the best ceiling fan, you should always assess whether the unit is durable and safe or not.
An appliance’s longevity is imminently connected with its manufacturing material. On a different note, the aspect of safety is just as crucial – especially if you have children or pets. For example, the blades of the window fan shouldn’t be exposed. Ideally, they should be secured by the outer grill. Always factor in this detail; as insignificant as it may seem, it matters.
Understanding How a Window Fan Works
So, how does a window fan work? The principle behind the operation of such a unit is surprisingly simple, yet efficient. Expressly, it can operate in two ways. One of them is by pulling in cold air from the outside. The second one is by pushing out the stale air from the inside.
In this view, it’s worth outlining that the way in which you decide to position the appliance will influence the principle behind the unit’s operation. There is also the option of installing a window fan for pulling in cold air and installing a different window fan for eliminating the stale air. This way, you can create the perfect indoor environment.
Still, we’ve pointed out before that some models facilitate a reverse function. To that end, you don’t need to use two separate fans to enjoy these benefits. All you have to do is simply change the operating mode, and that’s about it. Plus, there are many models on the market that incorporate two sets of blades that run independently. This is why these models can perform both functions at the same time.
Key Guidelines on Using a Window Fan
Without a doubt, investing in a high-quality window fan will enable you to cool down your house without having to pay a small fortune in this direction. We could say that such a unit is an energy-saving, economical solution. In fact, you can even use it as a supplement to your air conditioning system, granted that you position it correctly – this is very important.
Make sure you follow our guidelines in this respect.
While most windows are likely to easily fit into a common double-hung window frame, there are still some exceptions to the rule. In this respect, you have to lift the lower window frame. The next step is inserting the fan into the frame while lowering the sash back. This way, you can be 100 percent confident that the fans remain sealed in place by the support and weight of the window.
On a different note, many window fans on the market are specifically personalized for sliding windows that are made to open horizontally. However, note that the installation process remains the same, as similar principles are followed.
The Importance of the Fan Direction
During the day, as the level of humidity rises, the air inside the house changes, as well. To that end, one of the most efficient techniques of keeping the air inside the house cool is by pulling cool air in overnight.
In fact, some models even turn on automatically, as soon as the temperature and humidity levels outside are lower than indoors. On the other hand, during the warm part of the day, the window fan will concentrate on pushing the hot air outside the house.
How to Install an Extractor Fan in a Window?
If you want to pursue the DIY approach for installing an extractor fan in a window, then you’ll definitely find the next tips helpful. If you’ve already installed a unit like this, such as a bathroom fan, you’ll find the process quite easy and accessible.
- Pick the right place for the fan. This is important; as picking the right window will contribute to removing condensation and eliminating unpleasant odors. As a rule of thumb, fans have to be located at least 1.8 meters from the floor. Concurrently, they should be positioned in the proximity of the place in which condensation is likely to occur.
- Measure up space. Before proceeding with the installation process, you should measure up the exact spot where you’ll position the window fan. Depending on the type of fan you’ve chosen, you’ll have to measure the size of the hole. Bear in mind that the fan housing is larger than the whole. Thus, you should leave enough space around the hole for this purpose.
- Cut the glass. Make sure that, if you do cut the glass yourself, you have appropriate safety equipment, such as gloves, goggles, so on and so forth. In addition, you should cut around the marked glass, for the best results.
- Install the extractor fan. You should complete this step only if you have the right tools for it. At the same time, bear in mind that you must respect the IEE regulations (institution of electrical engineers regulations). If you’re not knowledgeable in doing wiring and electrical work, it would be best to request the assistance of a professional, to be on the safe side.
- Link the fan to a switch. Before doing this, you should determine whether you want the window extractor fan to work off a switch or a pull switch. Afterward, you can go on and connect the cable, according to the instructions provided by the manufacturer.

Main Benefits of Using a Window Fan
Before you consider making an investment, it’s important to take the time to analyze the ins and outs of the purchase. We want to make it easier for you to take a decision by briefly presenting the benefits associated with using a window fan.
- Convenient, energy-saving alternative. In comparison to a typical AC system, a window fan is much more affordable, not to mention that you can save a lot of money on the energy bill by choosing this alternative. Most notably, it can efficiently be used for home cooling. And, presumably, the best part is that it really fights against the unbearable summer heat, without the astronomical costs.
- Excellent addition to your AC system. If you already have an AC system installed, then you might consider adding a window fan to your household to maximize its efficacy. That’s specifically because an AC system isn’t equipped to clean the air around the same way a window fan would normally do. To that end, combining these two appliances will ensure that the quality of your indoor air is good.
- Fresh air circulation. We’ve briefly outlined the perils of indoor pollution, which is just as severe as outdoor pollution. The good thing about a window fan is that it is fully equipped to eliminate unwanted odors from the bathroom, bedroom, kitchen, living room, so on and so forth. At the same time, whenever something gets burnt in the oven, thanks to the exhaust function, you’ll get rid of the smell right away. Check out the top rated outdoor fans here!
- Reduce the costs associated with your AC system. When you use an AC system and a window fan, you’ll manage to significantly cut down the costs of the AC system. Usually, these bills can be quite high, especially in the summertime.
- It easily fits most windows. If you’re worried that the installation process for a window fan is time-consuming and difficult to follow, you can rest assured; that is hardly the case. In fact, most state-of-the-art models incorporate adjustable panels, which significantly simplify the installation process.
We also reviewed tower fans to make the warm seasons a bit cooler!
- What window placements should I avoid?
Typically, you should steer clear of placing your window fan in the proximity of parking areas, or garbage areas. That’s because the fan will redirect the odors from those areas into your house, and you don’t want that, of course. At the same time, it isn’t necessarily a good idea to locate a window fan near a fridge or a freezer. That’s because this will maximize the load of the unit.
- When is using a window fan not recommended?
If the nighttime air in your area isn’t cool, then perhaps you shouldn’t invest in a window fan. At the same time, granted that the air outside is excessively polluted or humid, an intake fan isn’t recommended.
