REASONS TO AVOID

Not very powerful

Poorly designed controls

The Lasko W09560 is a reversible twin fan unit with three speeds, plus intake, exhaust, and air exchange settings. Other features include temperature control and a unique Bluetooth connection with a smartphone instead of a traditional remote control. The app is user-friendly and effective at controlling the speed and settings. Installation is a breeze, as the extension panels easily slide to fit either horizontally or vertically oriented window openings.

The manual controls were less intuitive, and we preferred using the Bluetooth option to control the fan. The digital interface does not display what setting you are on until you change it. We also didn't find the window fan to have much power. At 13 feet, it gives off just the slightest gust of moving air. If you do not necessarily need a powerful breeze and want to circulate the air in your room, this fan does precisely that.

The Air King 9166F 20" moves enough air to create circulation throughout a moderate-sized house. When set to high, the air movement at 20 feet is equivalent to a stiff breeze — the manufacturer claims 3,560 cubic feet per minute when set on high. The fan controls are straightforward and effective with intake/exhaust functions and high/med/low rotational speed settings. One unique and convenient feature of the Air King is that its design allows you to leave it in place whether the window is open or closed.

We can't deny that the Air King is a powerful unit, but the trade-off is that the large blades and hardy motor that put out all of that power also produce a lot of noise. When set to high, we measured 76 dBa. Also, while we like that you can open or close the window while this window fan stays in place, this is because the fan screws into the window trim, meaning it becomes more of a permanent fixture than some may prefer. If you don't mind this factor and want to move a significant amount of air, this unit will likely blow you away.

Dimension: [21 3/4" - 33 1/2"] x 10 3/4" x 4 1/4" | Remote: No

REASONS TO BUY

Simple user interface

Doubles as floor/table fan

REASONS TO AVOID

Fans unidirectional

Only two speeds

The Comfort Zone CZ319WT is a minimalistic, cost-effective window fan. Installation of this unit is a cinch with the twin sliding panels that fit it to the double-hung window gap, and it comes with a bug screen, effectively sealing the unit. The easy fitting means that, while the fan direction is one-way, you can quickly flip the unit around to exhaust a room as well. Moreover, the directional airflow coming off the twin 6" fans feels like a steady breeze at 20 feet.

This fan was markedly cheaper when we initially purchased it; prices have since fluctuated online. If you can find it for a reasonable price, we still maintain that it's a great value.

While we like the savings that the Comfort Zone offers consumers, it does not come without a few cuts in performance and features. As mentioned above, the fans are unidirectional. In addition to that limitation, the unit only has two settings — high and low. However, making up for these shortcomings are feet that support the unit as a floor or table fan.

REASONS TO AVOID

Rests on window sill

Narrow base

What makes the Treva a standout in the class of window fans is that it does not rest in the window but on the window sill. Its slender profile and option to run on 6 D-cell batteries if needed make it a good choice for personalized airflow as well as travel. This versatile fan is no slouch when it comes to moving air, either. The machine produces a wind speed of 4.5 mph at 3 feet which creates a gentle but detectable breeze as far away as 20 feet.

While this fan's slender profile makes it easy to pack, it lacks the security of being secured in the window frame when in use. A stiff breeze from outside could potentially knock it over. Additionally, its airflow is one-directional, and there is only one blade doing the work. For anyone considering this unit for travel, keep in mind that when it's loaded up with batteries, that adds 2.5 pounds to its weight. Despite these limitations, if you need a fan for your on-the-go lifestyle or a window far from an outlet, then you can't do much better than this petite air mover.

Dimension: [24-1/4" - 37"] x 13" x 3-1/2" | Remote: Yes

The Bionaire 8.5-Inch Reversible Airflow is an all-around great performing window-mounted fan. Its twin 8" blades have three settings that are reversible, allowing air to be pulled into a room or pushed out. The user interface controls are easy to read and operate and cover a wide variety of features. For example, the air exchange function allows users to set a thermostat such that the fan will draw air in or out of a room depending on the desired temperature. The Bionaire produces airspeeds as high as 11 mph (measured at 6") and can be felt as a decent breeze at 20 feet.

We found little to complain about with the Bionaire; however, certain features will make it a no-go for some shoppers. First off, the window width requirements were measured at 24" to 37" — though one may purchase extensions if needed — and it is best suited to double-hung, sliding, and casement windows. Additionally, we were less than impressed that the remote control only works within a range of 15 feet. That said, this unit is pretty darn quiet (58 dBa on high), considering that it sports two fans and produces high airspeeds.

Dimension: [24 5/8" - 35 3/4"] x 12" x 4 1/2" | Remote: No

The Holmes Dual 8" Blade Twin is a high-performance dual-fan system that offers users plenty of adjustment with analog controls. The 8" blades are independently controlled to facilitate air circulation by having one drawing air in while the other pushes it out or having them work in unison. Additionally, the thermostat allows one to set the circulation to a discrete comfort level. Finally, the noise level on this model is minimal (57 dBa on high) in light of the powerful twin motors.

The main problem with this fan is that the unit best fits double-hung windows in the fairly narrow range of 24 5/8" x 35 3/4". Additionally, the thermostat does not have actual temperature values but rather a series of discrete levels indicating more or less cooling action. The unit also lacks a remote. Despite these shortcomings, we like what this unit has to offer, particularly the dispersed airflow that seems to better distribute air around a room.

Dimension: [25 1/4" - 36 1/2"] x 7 1/2" x 2 3/4" | Remote: No

The 3-fan Holmes Group Bionaire BWF0522E-BU is a uniquely designed machine in that the adjustments in wind speed and temperature are controlled by the number of fans actively spinning. Thoughtfully, the fan's extension panels are capped with rubber, effectively damping the fan's vibrations and helping to further reduce the noise output (50 dBa on high) of this relatively quiet machine. The unit easily fits a variety of window types as it can be set vertically or horizontally with adjustments in height/length made with the flip of a locking tab. This fitting also means that, while the motors are unidirectional, the whole unit is easily spun 180º to run as an exhaust fan.

There is a lot to be said for simplicity — particularly for a fan. However, the fact that this unit is controlled by a single button causes some frustration as you have to cycle through all the settings to get to a particular one. That said, we really like that the Holmes has temperature regulation settings between 60º and 80º F and that it can easily be installed vertically if needed.

Dimension: [26 1/2" - 38"] x 21 7/8" x 8 1/4" | Remote: No

The Lasko 16" Electrically Reversible's big fan blades and powerful motor provide sufficient airflow to warrant the label of whole house fan. This unit kicks out 11 mph wind at the source and can be felt as a breeze at 20 feet. However, this unit has a more dispersed airflow as opposed to a direct/focused flow which is preferable for circulation in many cases. Additionally, the unit has three speed settings as well as reverse. As far as the window fitting goes, this unit works on several window styles because it mounts to the trim allowing many windows to close behind the unit.

While the Lasko 16" is competitively priced within its subcategory of high volume fans, that is not to say that it is inexpensive. Moreover, the relative savings do not come without performance cuts. Specifically, the fan lacks a remote, and it isn't what we would describe as quiet — we recorded the sound output at 68 dBa on high. The unit also lacks temperature controls, and the single fan precludes it from having an air exchange function. Despite these shortcomings, we find the simplicity and effectiveness of this fan refreshing.

Dimension: [23 3/8" - 37 5/8"] x 12 1/4" x 3 1/2" | Remote: Yes

The Comfort Zone CZ310R has twin fans with 8" blades. The unit has 3 speeds as well as cool, exhaust, and air exchange settings. It has a remote that's super easy to use, as are its onboard controls. The fan installs fairly easily on double-hung windows in the horizontal position with accordion extensions on either side of the unit. Also, it is reasonably quiet at 50 dBa.

Conversely, the CZ310R puts out a pretty weak airflow which we measured at 5 MPH on high. This produces just a hint of a breeze at 15 feet. While we like the remote that comes standard with the unit, we always find it frustrating when a company doesn't include batteries which is the case with this model. Also, we found the accordion window fitting extension to be difficult to adjust to its full extension. However, we do like that this model comes with feet to make it function as a floor or table fan.

Why You Should Trust Us

Senior Research Analyst Austin Palmer has worked in electronics testing for the better part of a decade. He has tested everything from table fans to air purifiers to portable air conditioning units. The man knows a good quality fan and can back up his conclusions with the data derived from his detailed testing and analysis. Similarly, Senior Review Editor Nick Miley has several years of experience in product testing and analysis. His work is informed by his background in original scientific research as well as a previous occupation in wind turbine maintenance and repair.

Together this duo created experiments and evaluations that isolate all the aspects of fan performance. Specifically, the analysis looked at airflow, controls, set-up and noise, and more. The result of their work is an easy-to-digest product comparison with practical information derived from hands-on experience.

Analysis and Test Results

Many fans look alike. As such, we bought and tested all the products in our review to see which blew us away and which just blew a whole lot of hot air. To structure our review, we separate our investigation into categories or metrics that cover all aspects of a quality fan. These are wind speed, noise, controls, and ease of installation. The following is a detailed delve into each metric, including the products that did well in each and why.

Wind Speed

We measured wind speed at 6" inches distance from the center of the fan when on high using an anemometer or wind meter. The Bionaire 8.5-Inch Reversible and Lasko 16" Electrically Reversible are considered to be high airflow machines producing 11 mph wind speeds. The Holmes Dual 8" Blade Twin and the Comfort Zone CZ319WT fall into the average category at 8.7 mph and 8.2 mph, respectively.

In a less scientific test, we also measure the air movement at a distance. This is done by laying a tape measure on the ground perpendicular to the fan measuring out 30 feet. We start at 30 feet and walk towards the fan until we can feel the air it's moving on our cheeks. Most models here reviewed register a breeze at 15 - 20 feet. However, the King Air lived up to its name by issuing a strong breeze at 20 feet and noticeable air movement beyond 30 feet. The only model that approached that kind of power is the Comfort Zone CZ3139WT. We were able to feel some air movement with this unit at 25 feet.

Noise

Though some folks like white noise, many people do not want to listen to a fan whine. We measured each unit's noise output while running it on the highest setting with a sound level meter (measured in disciples). As you might expect, the most powerful fans are the loudest. The Air King produces 76 dBa. To put that in context, that's about as loud as an electric lawnmower!

On the quieter end of the spectrum is Holmes Group Bionaire BWF0522E-BU at 50 dBa — quiet enough to go unnoticed. However, this fan doesn't produce much air movement. A good balance between air movement and noise output is struck by the Holmes Dual 8" Blade Twin, which kicks out a respectable amount of air while maintaining a moderate noise level of 58 dBa.

Controls

This metric looks at knobs, buttons, dials, and remotes that adjust, set, and otherwise operate the fans. Top models with remote controls are the Bionaire 8.5-Inch Reversible Airflow, Comfort Zone CZ310R, and uniquely, the Lasko W09560, which makes use of the user's smartphone to control the fan via an app and Bluetooth connectivity. We found all three of these models very easy to operate, but the Lasko W09560 stood out with the modern ease of use and customization available through the app.

Those models with push-button controls and digital readouts are the Holmes Group Bionaire BWF0522E-BU and the Lasko W09560. These models offer the most difficulty in operation because you have to cycle through options to get to the sought-after settings. Those with control knobs are the Air King 9166F 20", Holmes Dual 8", and the Lasko 16" Electrically Reversible. Finally, the Comfort Zone CZ319WT uses a switch system. The knob and switch models are by far the easiest and most intuitive to operate.

Ease of Installation

Interestingly, almost all of the contenders in our lineup passed this test metric with flying colors. Most of these models require the user to set them into the window track and either expand a panel or close the window onto them. That's it. However, the large fans, such as the Air King and the Lasko 16" W16900, are the exceptions. While we don't want you to get the impression installing these models is challenging, they do require tools to screw them into place. Besides that, though, installation is relatively easy.

Conclusion

There's more than what meets the eye when shopping for a window fan. Our review closely examines all aspects of these handy appliances, so you have the details you need to select the right product for your needs and budget. So, take advantage of our hard work, and your journey to find a new window fan will be a breeze.
