Though you could debate whether this model is a ‘box fan’ due to its shape, I had to include the Lasko 3300 and here is why.

Like other box fans, it has your usual features such as your handle, 3 speed settings, feet for stability, however where this fan stands apart is with its ability to rotate the fan blade direction. Very few offer this feature.

Again it is probably debatable if it could be considered a traditional ‘box fan’ but the Axial is another worth mentioning.


If you want a small powerful cooling fan this product could be your best choice. It is specifically designed to be small and powerful, so it certainly won’t work in all applications, but for those very specific times you might need cooling or ventilation, this fan is perfect as it provides great airflow.

Unlike others, it can be mounted and it is made from aluminum metal, not plastic, so you are getting a higher quality.

It also has larger model options.

There might be other more durable products available.


11. Hurricane Box Fan 20 Inch | Classic Series 


The Hurricane box fan is probably a good option if you are looking for a fan that blows a good amount of air but you don’t mind the noise.

The consensus seems that this fan blows quality air but is quite loud.

It comes with a nice wee tilt feature, where you can tilt the fan around 15 degrees and direct the airflow slightly more than your average box fan.

The speed dial for the fan is contentious in its placement.

The dial is located inside the fan area where other fans generally have their dial on the top.

Like most box fans the Hurricane has 3 speed settings.

By having it in the fan area it means there are no obstructions if you use the fan in the window, however, a number of customers did mention they were not overly happy about where the dial was placed and preferred having it on the top of the fan.


Having sifted through hundreds of reviews there seems to be a general consensus that this Hurricane box fan is quite loud for a box fan.

It seems to blow a lot of air but at the expense of noise.



12. Lasko B20401 Decor 20″


Much like the Hurricane box fan above, the Lasko B20401 is one of those fans that seem to trade off airflow for noise.

It got a lot of feedback about being loud but also moving a good amount of air providing solid air circulation.

It comes with small attachable feet that can be put on and removed at will. This adds a little more stability to the fan.

The defining feature of this fan is the fact it comes in black.

Many purchasers made the decision to buy the fan due to its color and style, even saying that even if it is dirty it tends not to show up like on other, white fans.

It comes with a handle on the top of the fan for easy portability and also has the 3-speed dial on the top of the fan, much like other Lasko box fans.


Much like others, a few recurring criticisms were made in regards to the build quality.

It was also mentioned a few times that this fan can be a little unstable and fall over a little bit too easily.



13. Lasko 3733 20″ Box fan 


The Lasko 3733 box fan comes in a couple of colors, grey and black which is a popular choice as it looks more stylish and also does not show the dirt like lighter colored fans.

It has 3 speeds and the speed dial is on the top of the fan also, like other Lasko fans, it comes with a handle on the top for easy portability.

The fan is ETL listed, so has passed safety testing, however unlike a lot of other Lasko box fans, this particular fan does not come with weather resistant finishing, so is not ideally suited for windows where the fan will face the elements.

One customer tested this fan along with a number of other box fans and found this fan used mid-range power (w) compared to other similar fans, though the amount of power between their fans, and what they end up costing is negligible unless you count your money right down to the cent.

During the test, this fan was also recorded to produce medium-range noise compared to others.

Windflow measured in similar, so all in all, this fan sit around the middle range for box fans in terms of output. (source – first review)


Not unlike other box fans, some units fall victim to poor construction and materials, causing defective units.



14. Mainstays 20″ Box Fan


Mainstays 20-inch box fan is good value for money.

The fan itself has 3 speeds and its construction has minimal screws and snaps into place rather than being screwed together around the unit.

This was one common complaint people had as it made it hard for people to take apart to clean the fan.

The blade design is a little different to other box fans and was commented on by a number of users about how this helps produce more airflow.

The fan is sturdy and has a good base which means it doesn’t succumb to tipping as some other fans do.

It also comes in a number of colors including black which many people prefer due to dust not showing up and the fan not looking dirty all the time.

The controls for the fan are found on the face of the fan, rather than the top like the Lasko fans.


Hard to take apart to clean.



15. Lasko #3723 20-Inch Premium Box Fan 


The Lasko 3723 is probably what you would call a run of the mill box fan.

According to one reviewer who tested a number of fans this fans stacks up about the middle of the pack when it comes to power usages (W) noise and airflow.

That’s is neither bad nor good, which in a sense sums this fan up.

For the most part, the fan gets positive reviews.

It does what it is meant to do – blow air.

The speed dial is on the top of the fan and so is the carry handle like the other Lasko fans we have reviewed in this article.

It has a durable steel body and has 3 speeds as well as being ETL listed.

Unlike the 3720 however, it does not have weather-resistant coating so this is not a fan you are going to want to use when exposed to the elements.

But again, sadly, being a cheaply made product with lower quality materials some units are susceptible to quality control issues.

Most of the time you are likely to get a reasonable box fan, but just in case, remember to keep a receipt and not settle for a lemon.


It is not weather resistant and on occasion suffers from quality control issues.



What to look for when buying a Box fan.

Box fans - What to consider


• Power / CFM

An important consideration with any fan you purchase is how powerful the fan is.

Wind power in a fan is measured by CFM’s and the more CFM moves, the more powerful the wind power (generally speaking).

For the most part, CFM in a box fan does not differ all that significantly and may range from around 900CFM to 2500 CFM.

You can see a comparison of some of the more powerful box fans here.

With all that said, the difference 1000 CFM will make will be significant so it is wise to decide how powerful you want your fan to be before you buy.


• Size

You will likely find most typical box fans are about 20 inches.

However, if the particular size is important to you-you will want to check the other dimensions.

For example, many people use box fans in their window, and window panes will differ in size and space.

There is no point purchasing a box fan for the window that won’t sit correctly.

If you just intend to use the box fan on the ground or somewhere similar, it may not be as big of an issue, but the size of the fan is always worth thinking about before you buy.


• Features

Unlike a lot of other fans, you will likely find that box fans typically don’t have a whole lot of features and often no remote control.

There might a few little design elements like a carry handle, small leg stands and obviously a speed dial, but outside of those box fans do not tend to vary much in terms of features.

• Application

There are a few different applications for a box fan and the considerations for each may be a little different.

Often people will use a box fan on the ground, or on a table and there are a few things above and below to think about.

However, a common application for a box fan is using them in the window as a window fan.

First, you may want to consider is a box fan or window fan best for this application?

If you do decide to go with a box fan it is worth considering the following things:

  • Where is the speed dial?
  • It may seem like a silly question but there are some box fans out there that have the speed dial on the back of the fan rather than the side or top.
  • This obviously makes things a pain in the bum to change speeds along with making it a less efficient fan for using in the window.
  • Weatherproofing
  • If your location is susceptible to the elements then you will want to make sure that you get a box fan intended to withstand them.
  • Not all box fans are made for that application so before you buy, ensure you look for a box fan that is made with materials that can deal with the exposure conditions or purchase a fan that has been weatherproofed.
  • Detachable feet
  • Having the feet at the bottom of the fan has known to cause some issues when the fan is being placed in a window. Does the fan you are purchasing have removable feet? Or does it not have any at all?
  • Size
  • As mentioned above, measure your window first and make sure you are buying something that is going to fit in that space.


Box fan Noise meter


• Quiet Box fan

If you are looking for a quiet box fan, we recommend the Mainstays Box Fan.

In the application you intend to use the fan, will the noise bother you or do you need a quiet box fan.

For example, if you are putting your fan in the living room where you will be watching TV, then ideally you will not want a loud fan.

On the other hand, many like, or even need some white noise in their bedroom when they are trying to sleep.

This is very common and box fans actually serve this purpose well while also providing cooler surroundings.

Consider where you will be putting the fan and how much a noisy fan is going to impact your purchasing decision.


• Energy Usage

Box fans are really very energy efficient as they are and most wouldn’t use over 2 cents per hour. They are designed to provide a cheap cooling option. We will run through the cost metrics a bit further below.


• Filters

Filters are an additional feature that you can add to a box fan in order to purify the air.

You can purchase box fan air filters which sit over the top of the box fan.

This is great if you are using your box fan in the window as this can help alleviate pollens and dust which, if you have a sensitivity to, can really make a difference in comfort.


Box Fan FAQ

We mentioned above the cost of running a box fan is very cheap.

Box fans use very little power and are really, a very cheap way to help cool your room.

While they may not replace an air conditioner, they can certainly help reduce their usage.

Below are some common questions about box fans and their energy use.


• How much does a box fan cost to run?

How much does a box fan cost to run


Box fan power consumption

Let’s take one of the most popular box fans as an outlier.

The fan has 3 settings and uses the follow Watts per setting:

1- 74W

2- 95W

3- 111W

Let’s assume the fan runs for 12 hours a day at 10 cents per kWh.

That would equate to (annually):

1 – $32.4

2 – $41.6

3 – $48.6

Given that you are not likely to use the fan every day of the year, the cost is likely to be around 1/4 less (if we presume a season is a quarter of the year).

Those are very low energy usage stats.

• How many amps does a box fan use

Again we will use the aforementioned box fan as an outlier.

That box fan uses the following amps:





You will likely find most box fans amp usage might vary a little but will be in very close vicinity to this particular box fan.


How many watts does a box fan use


• How many watts does a box fan use?

As above, watts on a box fan will be different from model to model, you will find the watt range to be from around 45W on a low setting to 110W on a high setting.

What are the alternatives to box fans?

Floor fan - box fan alternative


In our comprehensive article about the different types of fans, we run through all the various types of fans for the home and what each might be good for.

In this case, if you are looking to use your fan in a window but do not want as much power you could have a look at window fans.

If you are looking to use your fan on the floor but need more power, could look at a floor fan, pedestal fan or tower fan.

Pedestal fans offer more features and more height and direction control and convenience with remote controls.

Tower fans offer similar options to the above, although the fan itself is usually not as high as standing fans and they also tend to be less strong.

Floor fans are basically the big brother of a box fan, so if you are looking for an industrial box fan, this is your best option.

They are very simple in regards to features and simplicity but offer far more power, but compromise on manoeuvrability and you obviously won’t be able to use in a window!
