A lot of my friends have been asking me about box fans and some have read Lasko box fan reviews and are tempted by what they have seen, but aren’t sure if they’re powerful enough.

Lasko is a popular brand that makes many different types of fans and other air-related products. They have a wide selection of box fans, which we have reviewed here.

Why has the Lasko brand become so popular when it comes to box fans? And, do they make the right type of fan for you? We explore more here.

Lasko: Presenting the Brand

Presenting Lasko Box Fans

Lasko has a huge range of fans and this includes their line of box fans. In order to fulfill the needs of multiple customers, they’ve created box fans to suit multiple homes and environments.

What these fans promise is a portable and affordable option for use in the home, which is slightly different from what is required in a desk fan or tower fan. They are simple to set up and use and relatively compact.

Lasko box fans are available mainly in a 20-inch size and each of the products in the range is pretty similar, when it comes to design. These fans can save you a lot of space and are a great choice for those who wish to extract things from a room and keep the airflow high.

Though they’re a little different from window fans, they can do a similar job if placed near a window. This means that smells, smoke, and stale air can be moved out and fresh air brought into a room.

Before buying from the Lasko box fan range, consider whether box fans are the right choice for you. They’re compact and usually very portable, as well as good for shifting air, but they’re not the quietest types of fans.

Think about whether the fan’s white noise will be welcome or something you want to avoid and also consider whether the size of the Lasko box fan is going to be big enough to give the power you need.

Features and Benefits

The following features and benefits are common to the Lasko fan range and can help you decide whether they’re suitable for you.

Fans create a bit of white noise and this can sometimes be seen as a benefit and may even help you fall asleep. Even when it isn’t hot, some people use white noise videos, such as the one below, to aid their sleep and relaxation. Lasko’s guide to choosing a fan touches on this noise issue, too.

​The price is another big selling point of Lasko box fans. Box fans, in general, aren’t the most expensive type of fan on the market. But there is a bit of variation when it comes to Lasko’s box fan prices, depending on the features, and you might pay more for a weatherproof option, for instance. However, most are pretty affordable.

Most of the fans in the Lasko range have a setting for three different speeds, to allow you to choose the power level you need. This will also have an impact on the airflow and noise created by the fan.

Box fans are relatively efficient, too. The Lasko brand says that their products with “Save-Smart” cost under $0.02 per hour to run and, in this study by creditcards.com, it was shown that some box fans can even cost less than one cent per hour to run.

Portability is another vital feature. As well as being lightweight, all of the box fans in the Lasko range have a carry handle, meaning getting them from room to room is easy. This can make them far more convenient than tower fans, for example.

Final Verdict

All of these four box fans have their own pros and cons.

But when we rate them by comparing their features, the Lasko #3723 Box fan has the highest ratings among all four fans.

This is a splendid fan with many useful features.

It is a fully assembled smart fan that has the capacity to work at low, medium or high speed. To control the speed, an easy to use dial-type switch is present at the top as well. Reasonable price is also a plus point of this particular model.

On the downside, just like all other box fans this unit also has an issue of noise generation at high speed.

A dream model for middle class customers whose main limitation is the availability of resources.

On the second position is the Lasko B20725 Metal Box fan because of its complete metal structure and ability to provide an astonishing amount of airflow.

These features are what separates it from other box fans.

After buying this unit, you won’t be worrying about replacing it for at least 3-4 years. Lasko B20725 is also approved by ETL and OSHA which is a clear indicator of its efficient functionality. Heavy weight due to metal body hinders its portability. Noise production should also be kept in mind if you are planning on buying this metal box fan.

But overall, Lasko B20725 Metal Box Fan is a good choice for people who want to invest in a long lasting product.

On third position in this list of Lasko box fan review is the Lasko Cool Colors 20 inch Box Fan Durable Metal Frame Purple.

This unit is a little bit different in terms of appearance due to its unique royal blue color. This means that it can easily be adjusted even in the most well decorated rooms. It’s not all about its outer appearance though, it also is a durable fan equipped with lots of features. A speed regulator is present at the top of the fan with the help of which you can easily adjust its speed. It is an energy efficient fan which means that it will consume a lot less energy compared to other units, more specifically it will save you 2 cents per hour. Five plastic blades provide sufficient air even for large rooms.

Lasko B20308 box fan also has some disadvantages too.

The first one is its noise production which might be a deal breaker for most customers especially the ones that are light sleepers. Another thing that might create some problems for customers is its vibration at high speed settings. This is mainly because of its instable feet that aren’t suitable to handle its high speed vibrations.

Last but not the least is the Lasko 3733 20 inch Fan Box which is considered to be a simple yet efficient at what it’s designed for.

With its light weight structure, you can easily move it around single-handedly. Due to its light weight and plastic blades, the noise production by its operation is minimal at its best which is a plus. Also, it is specially designed to consume less energy compared to its counter parts which will save you a lot of bucks in the long run.

What might stop you from buying this unit is its simple functionality.

Unlike other products, Lasko 3733 doesn’t come with a lot of many features which mainly puts it into a low- medium duty fan category. Another thing worth mentioning is its vibrations at high speed which might be troublesome for some people. In short, this product is designed for lower or mid budget families.

If you want a reasonable priced medium functionality fan unit, then this is your best choice. Otherwise you should pick the ones that comes loaded with lots of features.

You may have seen Bionaire fans becoming more popular. Are you wondering if their products are worthy of the hype?

I’ve noticed a few of their models in multiple friends’ homes and wanted to explore more about the brand.

The manufacturer makes all sorts of fans, tower, pedestal, and table fans. However, in this article, we’ve put together a Bionaire window fan review to look at the brand’s features and whether their range of window fans lives up to expectation.

In this Bionaire window fan review, we will be reviewing 4 Bionaire fan units.

Here’s a List of the Best Selling Window Fans This Year!

Two of them are twin window fans and the other two are triple window fans. All of their features, pros and cons will be reviewed and compared at the end and it will help you get a clear idea about the performance of the fans.

So let’s have a look at them.

But first…

Presenting Bionaire as a Brand

The Bionaire brand was first launched in Montreal back in 1977 and was being sold in North America by 1983.

Image via bionairecanada.com

They didn’t start with fans, though. Initially, they made just Air Purifiers and Ionizers, with a focus on improving the quality of the air.

Bionaire’s brand is built on keeping people comfortable, and their website reminds potential customers that most of us spend on average 90% of our time indoors.

This comfort was expanded to making fans.

These were added to the brand in 2001, by which time Bionaire was also making Humidifiers and even Heaters. Between 2004 and 2009 they started to offer their products all over the world, expanding to Latin America, Europe, and India.

Bionaire manufactures its products in Canada, where the company was originally started, so they aren’t outsourced to China or elsewhere.

The company has retained this Canadian base in spite of the fact they were bought out in the 1990s by “The Rival Company”. This is an American maker of small appliances who own other brands including Crock Pot. They were then acquired by the Jarden Corporation in 2005.

Bionaire’s research and development commitments are impressive.

Almost every brand claims to be focusing on new products, but Bionaire regularly releases new models for the home as well as innovations in their range. They commit to thousands of hours of research improving home products, including window fans.

The Bionaire Window Fan Range

These window fans are an excellent way to harness the fresh air of outdoors and cool your home in the process. There are six currently manufactured products within the range of window fans offered by Bionaire, four of which are compared in this article.

Some of the products only have very subtle differences.

For example, there is a Bionaire® Thin Window Fan with Comfort Control Manual Thermostat within the range and also a Bionaire® Thin Window Fan with Comfort Control Electronic Thermostat. The thermostat is the only difference between these.

The ideal customers for the Bionaire window fans are those who have plenty of suitable windows in which to fit them, who can take advantage of this technology.

Also, think about where your window is in relation to where you are in the room. This article explains the sensation of airflow and how it can help you to feel cool. A window close to your seating area is best.

If you are looking for a fan for a room with no windows then it may be best to go for something like a pedestal fan or tower fan, which don’t rely on a window.

Before you purchase a window fan, think about whether you have a suitable window for the fan to go in, and match up the measurements listed on the product.

For instance, some window fans require a window which is 24-27 inches wide. Some others are more extendable to give more flexibility.

Features & Benefits

What are the key features which tend to be found in Bionaire window fans? Do these products have any specific benefits over other models?

First of all, they are thin and compact.

Bionaire fans are thin without sacrificing any of their power. This means they take up less of the window space in your home and still allow plenty of light to get in. Blocking out the light on a sunny day is not recommended, instead, reap the benefits of letting the light pour in! Many of the Bionaire fans are 25% smaller than their competitors, so don’t restrict your view of outdoors as much.

Second, they’re quiet.

Most of the products within the Bionaire range are pretty quiet even on the highest settings. They are often much quieter than tower fans and desk fans as the sound vibrations don’t travel as easily.

Then, they are adjustable.

All of the fans within the range are adjustable to some extent, meaning you don’t have to stick to the exact size of your window when buying. Instead, you can adjust the sides when you are installing so that it sits flush against the sides of your window. All of the fans have a minimum and maximum window size rather than one rigid size.

They are also backed up by impressive warranties.

A lot of Bionaire window fans and other products have a five-year warranty, so you can rest assured that your purchase is protected if you end up with a defective unit for any reason that isn’t your fault.

And finally, these excellently efficient products can save up to 40% of the energy compared to many other fans.

Harnessing the air from outside the window can allow the fan to function efficiently and save on your energy bills.

The Bionaire compact window fan comes with an amazing technology that lets it increase air velocity to up to 40%. This is, when compared to regular fan units, is quite impressive. It means that you will be enjoying 40% extra freshness of air throughout the day.

Conclusion

Despite its small size, the Bionaire ultra thin window fan is designed to fit vertically as well as horizontally in most of the windows.

Conclusion

This BWF0502E compact fan of Bionaire is an expensive product when you compare its features with its shortcomings.

It provides better cooling due to its ability of almost double air flow.

This Bionaire ultra thin window fan also has the ability to adjust in different sized windows (up to 37 inches) due to its extender screen. Its advanced less noise operation is very attracting feature for light sleepers. The striking feature of this fan is that it is designed in such a splendid way that it will provide an extra 40% increased air velocity when compared to other fan units.

When we look at its flaws, the high price is major drawback of this model. Presence of a single push button instead of remote control also made it difficult to use. If you want to change the speed of the fan you have to push the button many times which is clearly not a feasible option for people who want one touch for desired settings. BWF0502E model fans can only work in one direction so to change the direction of air flow one have to go through the cumbersome task of manually removing, turning and then reinstalling the unit again.

Final Verdict

Now that we have covered each and every fan unit separately, let’s have a look at their performance when compared to each other.

The Best

Among these four models of Bionaire manufacturers, the Bionaire  BWF0910AR-WCU Fan is the best.

This dual window fan has digital thermostat that made it comfortable in use under different environmental temperatures.

Its reverse air flow and quiet operation features give the choice to use this fan either in kitchen or in bedroom without any second thought.

Presence of remote control and LCD display are extra qualities of this splendid model that made it a favorable choice for usage at night.

Although BWF0910AR model of Bionaire company is real gem, only caveat of this fan is its difficult cleaning procedure.

2nd Best

The Bionaire Twin Reversible Airflow Window Fan is second in the list.

This highly efficient Bionaire twin window fan can be used as exhaust fan or airflow fan or both at a same time because of ability of its fans to operate independently. The model is very durable along with the support of 5 years warranty.

Water proof technology makes it a suitable choice for the places where there are chances of rain or accidental water spillage.

Thermostat control of this excellent machine enables it to maintain the temperature of room in a desired range.

The Bionaire compact window fan is third on the list when compared to others in this list.

This model of Bionaire is small in size but efficient in operation.

The Bionaire ultra thin window fan is equipped with 3 fans that can operate at three speeds (low, medium and high). Due to its built-in extenders screen, it has the capability to fit in various windows sizes.

Absence of remote control and no LCD display unlike the above-mentioned models puts it on the third place. Another major drawback of this model is the fact that its fans cannot function independently.

Fourth Best 

Last but not the least is the Bionaire whole-house triple window fan which is a powerful fan that comes with three fans for extra cooling.

However, its dependent fan technology and manual air flow reversing is what made it last on the list.

Its high noise at maximum speed is a deal breaker for most people. However, if you are planning to use it in a kitchen or somewhere other than where you sleep, then it might not be a big problem for you.

So whether you want a dual window fan or you are looking for a triple window fan for extra airflow, you have everything you need to know right here.

Pick the one that meets your requirement and budget at the same time!

You’re probably well aware that pretty pennies are regularly squandered keeping that air conditioner running in your room, all day and night.

If you don’t want to either melt into a puddle of your own sweat or spend a considerable amount on your electricity bill, you should consider investing in a powerful window fan as a viable alternative.

Feeling lost and don’t know where to start? No worries, I’ve got you covered. The following best window fan reviews will reveal some of the top-tier units on the market today.

Comparison Table

I’ll also cover all the information you need to know about window fans and I’ll even answer some of the frequently asked questions that I usually receive. Let’s jump right into it.

What Are Window Fans?

Window fans are fans that are designed to be fitted into an open window and they often feature sliding side panels that are expandable, so that the entire window opening can be covered.

Most window fans on the market today come in two styles: two smaller side by side fans or just one large fan.

You’ll also find that most window fans tend to feature two or three speed variations, which allow you to control the speed of the air exhaust or intake.

And, speaking of functionality, there are models on the market that are electrically reversible, allowing you to switch between the exhaust and intake modes. These models are highly recommended over their single-mode counterparts.

Window fans are usually packed with awesome features, such as:

• thermostats,
• adjustable grilles,
• shut-off timers,
• remote controls.

A window fan with a thermostat turns off automatically if the room temperature drops to a certain desired degree, which helps you save money that would have otherwise been wasted, if the fan remains on.

Adjustable grilles are a great feature to look for in a window fan because they allow you to control the direction of the airflow.

The remote control and shut-off timer features are pretty self-explanatory.

Most window fans today feature a plastic construction, which makes them lightweight, but takes away from their durability. Older models, on the other hand, tend to be made of metal and are much heavier and sturdier than plastic units.

Things to Consider Before Buying a Window Fan

Just like all products, not all window fans are created equal, and navigating through the endless deluge of products on the market can be quite confusing. Here are some tips that you should take into consideration when shopping for a window fan.

Size of the Window Fan

The size of the window fan should be the first on your list of priorities. Ideally, if you’re looking to install a window fan on quite a large window, you should definitely buy a twin window fan. This way you’ll avoid gaps between the frame of the window and the fan itself.

To avoid buying the wrong size, you should look for a window fan that features sliding extenders. With these parts extended, you can obtain a customized fit for your window fan, which eliminates the existence of gaps, keeping bugs and insects from sneaking into your home.

You should also consider purchasing a window fan that features detachable legs, which allows the unit to be transformed into a stand-alone fan, when needed. And remember, a small window fan can be a very strong window fan, don’t let the size fool you.

Types of Window Fan

Window fans are mainly divided into two different categories: intake and exhaust fans.

The main idea behind an intake fan is that it draws cold air from the outside into the house, while an exhaust fan pushes the warm, stale air that’s inside the house to the outside.

How you choose between the two types will depend on the placement of your window fan. On the sunny side of your house, an exhaust fan is the ideal choice because it’ll help push out all the hot air from the room.

On the shady side of your house, however, an intake fan will help make use of the cool air outside by drawing it inside.

Luckily, there are quite a number of units available on the market that are able to perform both functions with equal efficiency. Keep an eye out for models that feature the reverse function because it will allow you to switch between intake and exhaust mode, whenever you want.

Remote Control

Nowadays, almost everything is controlled remotely and window fans are no different. Units that feature multiple speed variations usually tend to have a remote control feature, so that you don’t have to change the speed settings manually.

Durability and Safety

A window fan that’s made of a strong and solid material is certainly going to last longer than one that isn’t. Thus, you should pay close attention to the materials from which the window fan is made, to ensure its longevity.

Another thing that you should pay attention to is whether the blades of the fan are secured or not. Blades that aren’t secured properly by the outer grill of the fan can be quite hazardous. Also, the intake of any floating object can render the fan useless without proper blade protection.

Shut-Off Timer

Although window fans don’t consume as much electricity as an air-conditioning unit, I’m sure you still want to reduce your utility bills as much as possible. A window fan which features an automatic shut-off timer is certainly the smart way to go, as you can set it to turn off in a few hours when the house cools down.

Noise Level

You’ll definitely run across a lot of fans that are a bit noisy, which can limit your options if you’re a light sleeper. However, if some noise isn’t a big deal to you, then you can choose any fan you want.

Weight

Heavy window fans are extremely hard to carry and even harder to install. Make sure that the window fan you’re about to buy has a lightweight construction, to ease the process of moving it from one place to another.

Main Benefits of Using a Window Fan 

Apart from their reasonable cost, window fans possess numerous benefits that will surely put an end to all your ventilation problems, without breaking the bank.

Constantly Refreshed Environment

A poorly ventilated area is just uncomfortable to be in, especially if there’s more than one person in the room contributing to the stale air through their exhalation. An example of this would be two people sleeping in a small room. This can lead to many respiratory health problems.

Window fans provide a simple solution to this problem by exchanging the stale air in the room with the air outside. It keeps the room refreshed and prevents any negative health effects.

Low Power Consumption

Did you know that your average central air conditioning system consumes around 3,000 to 5,000 watts of energy when used for about 9 hours per day? And, did you also know that a window fan uses around 35 to 100 watts to run for one hour? This is around 700 watts, on average, in 9 hours.

A window fan isn’t going to cost you anywhere near to what an air conditioning system costs. Get yourself a window fan and spare yourself an insane electricity bill.

Maintained Temperature

When it comes to ventilation, air conditioners don’t perform that well. They might provide the desired temperature, but they usually can’t get rid of any unpleasant odors in the room.

Window fans have the ability to exchange the air in the room constantly, which not only helps keep the room refreshed, but also gets rid of unwanted odors and stale air, while maintaining a comfortable temperature.

Great Addition to an AC System

Okay, enough bashing of air conditioning units. You can also work hand in hand with them.

You can use a window fan inside your house to boost the efficiency of your AC system. Like we’ve established, AC systems aren’t capable of cleaning the air within the room, why not combine both appliances together to achieve the most optimal outcome!

Compatible with Most Windows

Most high-quality window fans on the market come with adjustable panels which allow for an easy installation process. In a nutshell, all you need to do is fit the window fan into the window frame with the aid of its panels, plug it in, and enjoy the cool breeze.

How to Use a Window Fan?

The idea behind the direction of a fan’s airflow is pretty simple.

A fan is comprised of two sides:

• the open side
• and the grille side

Air flows across the fan’s open side and moves towards the grille side. So, for intake fans, the open side should be facing outside and vice versa for exhaust fans.

Window fans are pretty simple to use because they rely on fairly simple principles.

If you turn the fan on when it’s warm outside, the fan will blow hot air into the room. So it’s advised to turn the fan on when it’s cooler outside, to cool down the air in the room and lower its temperature.

This could also spare you from using the AC at night since the outside air temperature might have cooled off by this time. It’s a good idea to have another window fan installed elsewhere, to help you achieve a cross breeze.

If the nighttime air in your region is not that cool or if it’s highly humid, you should steer away from intake fans, as they won’t be that effective.

During bad weather conditions, it’s extremely important to remove all fans from your window frames. Unless your window fan has a water-resistant motor, a drop of water can lead to serious electrical damage in the fan.

Generally, a common window frame should accommodate most window fans.

You’ll need to insert the fan into the window’s lower frame after the frame has been lifted and the sash has been lowered. This will ensure that the fan is securely sealed in place.

Units that are specifically designed for horizontally-opened sliding windows follow the same installation process.

How to Install a Window Fan?

It’s always recommended to hire a professional to install a window fan, or any electrical appliance, for that matter. However, if you’re planning on taking the DIY route, you should go about it using the following guidelines.

You can also follow this video demonstration of how to install your newly-bought window fan.

• Pick the Right Placement – Picking the right place for your window fan is pivotal to its performance. The placement of the fan can counteract the effects of condensation and help remove unpleasant odors. When positioning your fan, it should be fairly raised off the ground. Additionally, you should place the fan in the place where the effects of condensation are usually significant.
• Remove the Window Pane – Before proceeding to install your window fan, you’ll have to remove the window pane. Removing the pane can be done easily with a double-pane window. All you have to do it is simply take it out of the casing. It’s recommended to substitute the glass with a Lexan section, which is a sturdy, see-through material that’s ideal for this situation. You can learn more about Lexan and what it’s made of here.
• Trace the Fan onto the Lexan Section – Start by tracing the outline of the fan on the center on the Lexan section with the fan casing as a guide. To achieve optimal results, make sure that the fan’s casing is positioned level and straight before tracing it onto the Lexan piece.
• Cut a Hole for the Fan – You can go about this in two ways. You can drill a hole in all the corners, then cut the Lexan material with a jigsaw. The other way is to score the Lexan piece with a glass cutter and then tap it out.The last method is much more efficient than the first, as it produces extremely clean cuts without leaving behind any ragged edges. The first method, on the other hand, can accidentally splinter the material and render it useless.
• Install the Fan – After finishing with all the cutting and drilling, and after installing the Lexan section, you can now take the window and place it back into its casing. After that, remove the fan’s front cover and slide the motor into the casing.
• Drill Holes for Screws – Place the case onto the Lexan piece and then mark the position of each mounting screw with a felt marker. Proceed by drilling the holes using a cordless drill. Make sure that you’re standing straight without taking any angled stance and drill directly into the Lexan.
• Set the Fan Inside the Case – After drilling the necessary holes for the screws, set the case again onto the Lexan and start screwing in the screws. Follow this with adding some locking nuts, to ensure that the case is secured. Now, set the fan inside the casing, place the cover over the window fan, and plug it into the nearest power outlet. Voila, you’re all done!

Frequently Asked Questions

Can one fan perform intake and exhaustion of air at the same time?

There are a lot of models on the market that can perform double duty, just not at the same time.

But, you can use two reversible fans to achieve the desired outcome. One fan will draw in cool air from the outside, while the other fan pushes out the stale, warm air from the room.

Can window fans be damaged by water?

Window fans can very easily get wet during rainy weather conditions.

However, most high-quality models tend to be rust-resistant and have a water-resistant motor, which ensures a certain level of security against the rain. In case of heavy rain, it’s advised to turn the window fan off or even remove it completely, if possible, to ensure its longevity.

Can I close my windows with the window fan fitted in?

It depends on the type of window fan that you have.

The majority of single-blade fans allow you to close your window without having to take the fan out. On the other hand, some fans lack this ability and you’ll be forced to take them out manually to close the window.

If you’re looking for a more cost-efficient alternative to your air conditioning unit, these best window fan reviews may be for you.  Window fans can be viable AC replacements in some conditions and make for good investments if you want a particular area of the house to be well-ventilated.  The ones listed below are among the very best on the market now and should see your ventilation and cooling needs properly taken care of.

Bionaire Twin Reversible Airflow Window Fan

This fan has both a remote control and an onboard electronic one with an LCD screen.  It is designed for windows anywhere from 24 to 37 inches wide and comes with a programmable thermostat that turns it on or off automatically in order to maintain a set room temperature.  It has reversible blades, 3 speed settings, and water-resistant motors.  It supports both vertical and horizontal mounting.

Pros

• Strong

• Fans can be set to move air in directions independent of each other

• Relatively quiet at the 2 lower speeds

Cons

• No night-dimming/off switch for LEDs

• Can be a little noisy in the switch from one speed to another when being managed automatically by the thermostat

This fan is a solid product with some nice motor muscle behind it.  It’s far from being a whole-house fan, but it’s still strong.  It can move a lot of air quickly and functions well whether on intake, exhaust, or exchange mode.  It’s not the quietest fan around, but it’s far from being the noisiest—at the lowest and middle speeds, it’s even decently quiet as far as these fans go.

Lasko 2155A Electrically Reversible Window Fan

This ETL-listed window fan is made for windows at least 22 inches tall and 26.5 to 34.5 inches wide.  The three 16-inch blades can be reversed so you can use them to blow air in as well as out.  The fan comes with a safety plug and also permits you to shut the window behind it when desired. Costs almost twice as much as the previous one.

Pros

• Moves a lot of air
• Reasonably quiet
• Doesn’t impede window closure in bad weather

Cons

• May not be sufficient for whole-house cooling in medium-to-large homes

This is an excellent fan for the money given how strong it is and how well it performs, but if your place is more than 3 rooms, it probably still won’t be enough to do whole-house cooling duty.  Nevertheless, it’s a powerful instrument, and it doesn’t put out as much noise as one might expect from its size.  With 16-inch blades, this is no baby, yet it operates very nearly as though it were one.

Whole House Window Fan

This AirKing model has huge 20-inch blades married to a 1/25HP motor.  The fan has 3 speeds, durable plastic housing, a front-mounted switch, and OSHA approval.  It is designed to fit windows 26.75 x 11.25 x 26.25 inches. More expensive than the previous one.

Pros

• Feels quite durable
• Storm Guard works
• Decently strong

Cons

• Can be noisy
• A touch pricy

This fan isn’t among the cheapest, but it does have some nice features to justify its cost.  Among these are the 20-inch blades—these move a lot of air, and they will serve to cool most modest spaces within minutes even on warm days.  They can be noisy, though, although a big part of it might be improper mounting, as the fan tends to rattle if you haven’t mounted it the right way.  The casing is not all metal, but it still feels rather strong, so you do not have to worry that it will collapse after a few months of use.

Holmes Dual Blade 8” Twin Window Fan

This dual-bladed fan has 2 separate motors that can move independently of each other.  They are reversible, offer 2 speed settings, and carry 8.5in blades.  It comes with water-resistant motors and a 3-year limited warranty.  It also has a one-touch thermostat. It is priced on the lower end of the price scale.

Pros

• Fairly easy to use

• Comes with a thermostat for automated powering-on and shutdown

• Moderately quiet

Cons

• Could have better controls

This is a modest little fan with better performance than one might expect for its price.  It moves air well—just don’t expect to feel gusts—and is about as quiet as one might expect for a fan of this size.  The thermostat is a particularly useful feature.  It doesn’t have the best controls ever, but they’re easy enough to figure out; they’re just not as quick to set as many other fans’ controls are.  It’s also quite energy-efficient.  It will probably suit people who only need to cool single rooms.

Holmes Dual Blade 6” reversible Twin Window Fan

Fitted with a pair of 6-inch blades, this twin window fan is designed for slider and double-hung windows. It has 2 speed settings and water-resistant motors.  This is the cheapest one in our review.

Pros

• Reasonably priced
• Very easy to install
• Comes with a screen that you can use as an extender

Cons

• Blades cannot reverse flow by electronic control

• A bit noisy

This is one of the smaller window fans, so of course it costs less than the rest of the items on this list.  Still, it’s reasonably priced. It won’t wow you with automation or electronic features like thermostats or independently-controlled twin motors.  Instead, it’s just a plain little window fan—and that’s probably what most of the people for whom it’s designed will like best about it.  It’s relatively low profile, easy to put in and put out, and is good value for the smaller rooms.

Conclusion

This really depends on the size of the space you need to cool, but most buyers will probably agree that the best buy here is the Lasko.  It’s not the biggest fan in the group, but it is a fantastic performer nonetheless and will cool more than one room quite effectively.  If your cooling needs are lower, you can go with the Bionaire instead, which has a number of really nice features to go with its decent muscle-power.
