Customers like the size of the fan. For example, they say it's a narrow fan that doesn't take up much room, it'll fit in a small space, and it'd be best for small rooms. The housing is much smaller in size, so it takes up less window area. Overall, customers are happy with their purchase and recommend it to others.

Customers like the wind. They mention it pulls cold air in so well from the outside that it almost feels like air. It cools off their room, sucks the hot air out, and brings in cool fresh air. They also say it's a good doorway fan due to its compact size and longevity. Customers say the cross breeze is pretty nice and the temperature drops about 10 degrees when they run it all night. They appreciate the Temp. control is excellent and it shows the how many degrees to set it for and fan speed.

Customers like the appearance of the fan. They say it's sleek, has a nice design, and is quiet. Customers also appreciate the dark blue fan blades and the matte black fan body.

Customers are mixed about the performance of the fan. Some mention that it works well for their needs, the controls work well, and the thermostat is vague. However, others say that the two fans had already stopped working, one of the 3 motors stopped working and the unit doesn't work for their purposes.

"...It is light and perfect so I can carry it easily in one hand...." Read more

Customers are mixed about the durability of the product. Some mention that it's reasonably quiet and pushes much air very quietly, while others say that it has a bit of noise as far as something rubbing when it is running, and that it makes a dangerous sounding popping speaker noise.

Customers are mixed about the airflow of the fan. Some mention that it moves a surprising amount of air, while others say that it didn't move much air on the 90 degree days.

"...This particular fan is gentle and it does help perfectly with air exchange as not only you can push out the air but also reverse or have some fans..." Read more

"...It does only moves air in one direction, so it depends on which way you face it for air flow.The remote is fine. Not great but fine...." Read more

206 customers mention108 positive98 negative

Customers are mixed about the speed. Some mention they love the easy temp control of utilizing 1-3 fans and the thermostat settings are cool. They also say the fan speed changes by running 1 or all 3 fans, and the panel on the updated fans allow you to preset temperature ranges so your fan will automatically. However, others say that the fan is not variable, the remote is not good, and modifying speeds is awkward. It is not a fast fan, and is quiet.

"...- FLUID REGULATION OF SPEED is pretty neat as you can adjust the speed as you like...." Read more

"...I wish fan speed could be controlled instead of turning on one by one.<Problem>..." Read more

"...It is ingeniously engineered for efficiency, quiet and to exhaust the air from the room outside you just flip it over. Fantastic thing...." Read more

"...try to manually spin the fan with my finger/pointer gadget it does not spin freely it acts like the motor is wired incorrectly...." Read more

215 customers mention0 positive215 negative

Customers are dissatisfied with the value of the fan. They mention that it's not worth the price, it'll be too expensive to replace, and the price keeps going up on each purchase. Some customers also mention that the controls are adequate but inconvenient.

"...Overall it’s a good unit. It’s kinda pricey, so depending on your needs and budget and orientation needs this is definitely worth a look." Read more

"...I hope you listen to me when I tell you not to buy this fan! It's a waste of money." Read more

So I got this window fan for my office. These space has my video games system, PC, etc. I work and game here. As you could imagine, running all of these electronics produce a lot of heat. I was looking for something that could exhaust some of this heat to cool the room down without having to use AC. This room has its own AC unit, as it's an add-on room and not originally part of the house.Out of the box, the unit is new. I address this because some of the reviews cite damaged products or used products. The fans spin fast. With that, there is some noise but it's not noise you couldn't just tune out. It's regular fan noises you would hear with any fan. It blows hard/fast, which is good.You can use it either to blow air from the window, or flipping it over, you can exhaust air out of the room. Biggest issue with this is the design of the unit. The main part is off center, which means it only sits comfortably in the window in one direction. You can see this in the pictures. Once I flip it around to use the exhaust, it's no longer flush unless I take off the screen, which I don't want to do.This unit extends. However, the max length is 3ft or 36inches. Unfortunately, my window is 44inches long. And that is my bad for not looking at that before purchasing. The cable is 6ft long. Knowing this, I still set it up to at least attempt to exhaust some of the hot air to cool the room. The room was 91F and after about 1 hour of running, I have a temp of 90F. I have two other fans blowing/circulating air as well.It's a strong fan, but it doesn't seem to cool my room effectively. Keep in mind though, that this fan isn't covering my whole window, so I don't know if that has anything to do with it. It might work better if you're using it to blow air from the outside as opposed to an exhaust fan.Also the sides do not sit flush to the window closing itself as you can see in the photos. The extension lock is only on one side so the other side kind of hangs there and tries to retract back into the unit. Should probably have a lock on both sides to avoid this.Unfortunately, this unit doesn't work for my needs so I will be returning it.

5.0 out of 5 stars This worked fabulously for me! Great output, relatively quiet, perfect for narrow windows.
Reviewed in the United States on July 30, 2019
I almost didn't purchase this unit because of the negative reviews. But I'm glad I did! For clarity, I purchased the unit with the digital controls (not manual). I have a couple of very narrow window openings in my home, so this being only about 7.25" wide made it ideal.

NOISE LEVEL: I read a couple of reviews that complained about this unit being very loud. Not sure if perhaps those were faulty units, or if I just got lucky - but mine is NOT loud at all. I actually found the sound of the motor to be very faint, and most of the 'noise' from my unit is just the sound of the airflow as the speed increases. I have it on the highest speed right now and while it isn't silent, it's very soft and quiet.

REVERSIBLE: There seems to be some confusion on this. The UNIT is reversible. The direction of the BLADES is not. So yes, you can reverse the airflow. But no, you can't reverse the direction of the blades themselves. To clarify - you can't reverse the flow of air with the touch of a button, you must reverse the unit itself in the window (take it out, turn it around, put it back in). Not as simple as flipping a switch, but still fairly easy - and there are controls on both sides of the unit so that you can turn it on or off and select the airflow speed no matter which direction it is facing.

OUTPUT: The wind from this thing isn't going to knock anyone over, but it's a nice, relatively strong flow of air - especially considering the small size and low noise of the unit. It has really cooled down the side of the house where I installed it, and the breeze is fairly strong and refreshing.

TEMPERATURE CONTROL: They have temperatures noted on the controls... I find this to be pretty silly. This is a fan, after all, not an AC unit. It does not have a thermostat, so the temperatures noted are totally meaningless. Take them with a grain of salt. If you want it cooler, turn up the speed - that's it.

Bottom line - I'm glad I decided to order this, and I'm about to order another. It works great, and it fits my windows. I'm very happy with my purchase.

5.0 out of 5 stars A great window fan from a great Canadian company!
Reviewed in Canada on June 26, 2023
The triple window fan measures 2' x 9" with 7" additional extensions for both sides. One of the extensions is hard plastic while the other side is an accordion style that can be expanded or detracted for added length. You could easily use it in a wider window in a horizontal position as it's quite easily held in place. You can also place it in a vertical window. There are controls on both sides of the fan which makes it adaptable to a right or left handed window. These three tiny fans have a surprising amount of blowing power. They can draw the air out or draw the air in. I've been buying them and other Bionaire products directly from the company online until a few years ago, when they suddenly stopped selling online. I had the sense then that they were preparing to go out of business. Today their website offers only filters and accessories for previous models, and is selling out existing stock through a few selected retailers. I'm super glad I found this one, and am also relieved that they last for an extraordinarily long time, considering they are window fans. Three years ago, each one cost $49+tax with free delivery, Now I was lucky to find one at nearly $200, and I was happy to pay it. Sadly, we've lost another fabulous all-Canadian company that made great products and could always be counted on to be reliable. (fyi: there is no remote control for this product but I had to give it a rating.)
