I just got the fan but I am really impressed! As mentioned no assembly is required so I was able to take it straight from the box and put it into the window. The fan is ready to operate and once I turned it on high I was surprised at how quiet yet powerful it is. It is the most quiet yet powerful fan I've ever owned. The design is perfect to fit securely in the window. The only thing that would make it better is having a longer power cord, but the cord is still efficient. Very happy with my purchase.

UPDATE May 2018: I've now had this fan for 3 and a 1/2 years and use it almost daily for 1 - 3 hours and it is still working great. I don't know what I do without it - it keeps me from having to use my A/C all the time to cool down my bedroom. Anyway, it is still working great so I still highly recommend this product. Really impressed with it. Best thing about it is how light it is - I can pick it up with one hand. UPDATE Feb 2017: I've had this for about 2 years now and I still love it and think it works great. I use this very often and have had no problems. The one thing I've noticed is that the temp gauge is not accurate to the interior of the room, but honestly it couldn't be since the gauge is part of the fan, so it is measuring right where the wind is and not the whole room. Would be a great feature for new ones to have a remote temp sensor! Anyway, for me this is not an issue since it's easy for me to look at my temp gauge and then just calculate - add 10 degrees or whatever. But I hardly ever use the temp auto off thing anyway since I just blast it for a while before bed to cool the room down and then shut it off. I use it all seasons except summer now because my place is so hot (heat is central to building) so I need to cool the room down when I get home. The fan will cool the room quickly - I can get it from 75 to 68 in about an hour usually, which is faster than my AC! Because it's so light I have also used it in the living room which is a huge open area with the dining room and kitchen and it works well in there too, even though it's a lot of space. I love this fan and would still highly recommend it. I'm buying another one for my mother today which is why I decided to come back and post an updated review. I will start with the caveat that I've only had this a very short time (a month-ish) and have only used it about 10 times so far. I will come back at the start of winter and update this review, after I've used it for a while. I know one of the complaints with the new version is that it breaks down quickly so we'll see about that. Also, I've only needed to use it for a couple of hours before I go to bed, then I turn it off, so I don't know how it is overnight. I have a ceiling fan so after this fan cools the room, I just use that overnight. So I really have a limited view for this review, but I'll tell you what I can. The pros: It's really, really light weight-wise, which I wasn't expecting. I live alone and am not strong, so this was good for me. It cooled the room very quickly and very well - down from 80 to low 70's in about an hour. I've only used the feature that blows air in with both fans. I don't really understand how blowing in on one fan right next to blowing out on another fan would make any difference - seems to me that just blowing in as much cool air from the outside as possible would work best so that's what I did. I had it on high with the temp on the lowest setting - the fans really blow hard so I liked that too. It didn't cool the room below 70 even though the temp outside was cooler than 70, but it made it totally comfortable each time I used it. I didn't find the noise a problem - sounded like my AC unit. I guess it;s not quiet but I like white noise anyway so if noise is an issue for you, you should check out the guy who posted a review with the sound clip to see if it's too much for you. I found it very easy to install (I never have the patience to look at directions and am horribly not handy nor mechanically inclined - actually I'm so mechanically challenged that I put this thing in the window upside down at first!). I just put it in the window and plugged it in, then pushed the buttons until it did what I wanted (i.e. turned it to the coldest setting 64 degrees and high fan blowing in). I like that it is shallow enough that I can put it my window with the screen still in so I dont' have to worry about bugs or birds, etc. But maybe this is true for all of them...The cons: You can't use it sideways so it will only fit in the big windows horizontally, like in the picture. Maybe this is an unfair con but I wish I could use it the other direction so I could have it in the small window now that I have my AC unit in the big window. I did try using it on a very warm (74) and sticky night and it did not do the trick. I didn't really expect it to but it didn't in case there are people looking to use this to replace an AC unit. But there are many nights I come home and my bedroom is 80 and it's nice out and I know I could just use the fan to cool it down but I can't because of the AC unit in the big window. It's not quiet but I didn't find it terribly loud, either. But as I said I like white noise so this doesn't bother me, but it might bother others. So far I love it. I think if it breaks down after not much usage then I would change my mind so I'll come back (if I remember...) and post another review after I've used it for a while.

I was very skeptical when buying the window fan due to the amount of mixed or negative reviews of its construction and built quality and how it will last or work or have any type of sound. However for my unit it has work amazingly for two particular needs. The first need is to of course ventilate a room with fresh cooler air from the outside which works amazingly. The other need when it is hot outside in the summer where an AC unit will do much better, I placed this in the kitchen which gets hot in the summer due to cooking and it works in two ways very well, the first way is that it airs out all the hot air in the kitchen which maintains the temperature to a stable lower temperature. It also has the ability of course to blow in air to cool off in the kitchen so that cooking can continue. There is of course a feature which has one fan blow in air and the other fan blow out air however these work varies depending on how hot it is. If it's too hot the feature won't work because of the overwhelming Heat. The cons that I find in this unit are the following. I do not like that the only color available when buying was white. This is a problem in the kitchen or anywhere because Grease, dirt, or any type of pollen or dust will show blatantly on the unit. Another thing that I dislike about this unit is the auto mode which is annoying and prevents it from working efficiently. For me this mode is useless and should have not been implemented. It is annoying to have to turn it off every single time you reconnect the fan to the power. Another thing that I dislike about this unit is the LEDs being on without having an option turn off the LEDs because they are bright red and if placed in a room where you sleep it will bother you in the dark. I do like the fact that it comes with a remote controller which makes it easier and more convenient to turn on and turn off the fans without coming in proximity. Another feature that I like that is Paramount is the fan speeds they are quite powerful even on the lowest setting. In particular my unit has no whining or any type of fan noise outside of the blowing of air in fact it is certainly quiet on the lowest setting however on the highest setting the noise is higher due to the power of the Wind coming through. So far I have had this unit for a couple months and it has been flawless and it fits most apartment windows I have not had any issues with this unit as of yet and for the price it is very well worth it. It is made out of plastic for the most part however it seems durable and for me I do not need the additional extension for my window I believe this could be plays vertically as well if needed but I do not require this and it seems that you can place two of these units vertically side by side if the window is large enough which could be a plus if such thing is needed. Overall your miles and experience may vary due to the variability of quality control however my unit seems to be a very good built unit and I would definitely buy again if needed.

This is a great fan. I had been using a Holmes fan in our bedroom Holmes Dual Blade Twin Window fan with One Touch Thermostat and decided to get a new fan for one of our bathrooms that does not have a ceiling exhaust fan, so that we can remove all of the steam and humidity from taking showers and baths. I decided to try this Bionaire and see how they compare. I ended up putting the Bionaire in our bedroom and the old Holmes in the bathroom, for a few reasons. This Bionaire has more power and sucks the hot air out of the room better. The motor must be stronger because I can tell that it doesn't struggle when wind is trying to blow inward. On the Holmes, if it is windy and air is trying to blow into the window from outside, it struggles and the fans slow down. On the Bionaire it basically keeps functioning as normal with no struggling. The Bionaire has 3 speeds, whereas the Holmes only has 2. The medium setting on the Bionaire almost seems as good as the high speed on the Holmes. The buttons on the Bionaire are better too. The Holmes button is sort of already pressed in and feels almost like it is broken... a sort of cheap feel. Bionair buttons are nice and durable feeling and easy to use. They click nicely when you push them, and you know you pushed them and they "took." The Holmes button sometimes needed pressed more than once and never felt like it pressed correctly. I like that this unit has the temperature display too so you know how hot or cold it is in the room and you can tell if it is working or not or which airflow direction is working better... If you set it at exchange and see the temp go up after a few minutes, you know that is not the setting you want, etc. My husband doesn't understand the concept of setting the fan to exhaust to suck out all of the hot air and pull the cool air from the air conditioning from downstairs. He thinks it should always be set to bring air in (so he can sit in front of the dammm fan and feel air and say it's cooler that way.) So, now with the temperature reading right there I can prove to him that bringing in HOT air from outside is not helping the situation and you need to remove the hot air from inside by setting it to exhaust. When he sees it go from 80-some degrees down to low 70's and 60's now, he believes me. Of course there are times when exchange will be better or it will be cool at night and bringing air in is fine, but for the most part in the heat of summer, during the day, you will want to set it to out, to exhaust the hot air to the outside. This fan does a great job of pulling the cool air from the rest of the house too, as long as we leave the bedroom door open. The remote on this one is a nice bonus too because if it starts raining during the night and pulling rain into the room, you don't have to get out of bed to switch the fan direction or otherwise change the settings as needed. I keep the remote right in our nightstand drawer beside the bed and never have to worry about it. If it gets too chilly or whatever the case is, I can just grab the remote and not have to get out of bed. I will see how well the Holmes does in the bathroom, but if it seems to not get rid of the humidity and steam so well as we get into hotter and more humid months, I will buy another one of these Bionaire fans. Overall it is great quality and great performance. Changing the settings is easy and straightforward - pick your speed and pick your airflow direction and that's all you have to do. On the Holmes, you have to press the same button a million times to cycle through all the settings when you want to change it or even to turn it off. It gets to be a pain in the rear after a while. You can also set this one for specific temps etc so it will shut off when your desired temp is reached and kick on again if it gets hotter or colder. Just a great unit all the way around.

Purchased 2 of these expensive qindow fans. Let me start by saying the single star is strictly based on customer service, or lack thereof. One of the units stopped working properly. I tried to contact amazon and they directed me to contact the manufacturer. Well that listing is not who you have to contact so I contacted the appropriate company once I was able to get a good contact for them (their main listed contact was no good). Once I got a response se (if took a while) they made me send video and pictures, which k did once I figured out how to get their email to accept them. They kept asking for more and more pictures. Had me write across the "lable" which isnt really a lable at all. And cut the power cord. Ok fine, field destroy it, got it. I have to do this at work so I know the drill. Then I had to write my name and date on a piece of paper and send more pictures of the cut cord and the paper and the written on unit. Ok done...THEN..... that wasn't sufficie t because they couldn't see the entire cord so I coiled the cut part up and took yet another picture. Complete cord shown, name and date on the paper, written on unit lable and guess what? Not sufficient. Im not exactly sure what they wanted but they said again the entire cord. I pointed out that the ones I sent indeed showed the entire cord. Then they said u edited picture...ummmm all I did was resized it to show everything clearly. Not sufficient. Trash day came around and my husband threw it out because well..it was trash. They Then said they would not warranty the unit because the pictures weren't what they asked for. Im not sure if they wanted me to stand on a ladder and stretch the entire thing out because im 5ft nothing and there was no way to do that without climbing a ladder. So unless you dont care about your money, dont buy these because the company does NOT stand behind their product even if its only a few months old. So im out the $70.00 and a fan.

This unsolicited, uncompensated review is for the BIONAIRE Twin Window Fan, Model BW2300. My wife and I don’t tolerate hot weather very well--we like cool fresh air circulating around the house all year long. Consequently, our home is centrally air-conditioned and we have a couple of air purifiers and several fans running most of the year. Even though we live in the Front Range of the Colorado Rockies, where the humidity is generally pretty low (often in the single digits), the hot dry air of summer can become uncomfortable for us. The outside air cools down after sunset and we normally run a table fan in our bedroom which is located on the far wall from the window. We thought it would be great to have a fan in the bedroom window to draw in the cooler nighttime air after the air conditioning shuts down for the night (we have the A/C thermostat set accordingly). Instead of having to re-locate the table fan to the window every evening, we decided to look for a window fan that suits our needs, and of course we turned to amazon. The BIONAIRE Twin Window Fan appeared to be our solution. There were two things we had to consider before purchasing this fan: (1) we have sliding windows and narrow venetian blinds. (2) Our two cats like to perch on the desk and look out the window. (Isn’t that what most indoor cats like to do?) We didn’t want to take this small luxury away from them and we wanted to retain the use and control of the window and blinds and still have a fan in the window*. The Fan arrived within two business days for Prime members as promised by amazon. The fan was triple-boxed (!) and arrived in perfect condition. The quality of the unit was evident right away after removing the styrofoam packing material. I temporarily placed the fan in our bedroom window and slid the window to support the fan just long enough to plug it in and do a run through after reading the owner’s manual. FIRST IMPRESSIONS: The fans move an unexpectedly large volume of air for their size. The fans are well-balanced and there is absolutely no vibration. In addition, this unit runs whisper-quiet at the two slower speeds and only slightly louder at the highest speed. There is a section in the description at amazon stating that each of the two fans can be set independently. This led me to believe that each fan had its own power, speed, and direction controls. This is not the case, but this should not be a concern as I don’t believe most users would need such an option. The “air flow” button has 3 options whose settings are indicated by LED indicator lamps: “in” (both fan blades spinning counter-clockwise); “out” (blades spinning clockwise); and “exchange”, one fan for in, the other for out. One reviewer commented that the labeling on the control panel could be better. Indeed, the unit has white lettering on a silver background, making it difficult to read. Black lettering would have been better. The included remote control is a plus, great for being able to change settings while laying in bed. OPERATION: The Power button cycles through “Off”, “Low”, “Medium, High”, and back to “Off”. I would have preferred separate On/Off and Airspeed buttons, but OK. There is a brief pause between these settings where the fans are not turning. This may be the manufacturer’s way of addressing problems of some users’ complaints that the unit shut down, possibly to a tripped fuse or circuit breaker within the unit. The “air flow” button exhibits the same kind of pause, probably to give the blades a chance to slow down before reversing direction. We are not using the thermostat function as we simply turn the fan on and let it run all night. This fan has a bright red LED which displays the temperature. For most of the day it seems to register the same temperature as a wall-mounted thermometer on the other side of the room. My wife and I have now become room temperature conscious and find ourselves gazing at the temperature readings. We have seen a low of 66 degrees in the early morning (not bad for mid-July), to a high of 80 degrees in late afternoon when the air conditioning is off. * NON-STANDARD INSTALLATION: To accommodate our cats and have the use of our bedroom window and blinds, I constructed a custom-made stand from heavyweight redwood 2 by 4s, and it sits firmly on our desk. (see photo). I set a couple of wood strips at an angle to form a pair of channels for the edges of the fan to sit in. We now have cool outside air coming in at night and don’t have to run our air conditioning. And, the cats can still look out the window. My wife and I agree that buying this product was a good investment, and we are very happy with our purchase.

If you live in a low-dust environment, or in The Truman Show, this fan may be a great choice for you. But if you live in a big city, it's a different story. I'm in Manhattan, New York City, where the heavy dust contains soot and sticks to surfaces, and the vast majority of us in apartment buildings don't have window screens. This fan is just a dust and grime magnet, and you can't take off the front or back panel, so the blades and interior are unreachable to wipe off. And, cleaning the closely-set slats of the grills is a long, tedious and difficult process. The only real care & maintenance instructions in the manual are not to get the motor housing wet, and not to use gasoline or solvents to clean the unit. But as for HOW to actually clean it, not a word. Per another reviewer here, who called Bionaire for help with this issue, the only suggestion was to wipe the grille with a cloth or to vacuum it, and possibly to use air in a can to clean the blades. Well, these suggestions do nothing to remove the oily city grime here. The dirt sticks on the white plastic blades. Blech. I have two of these fans: back in September of 2021, about 10 months ago, my sister (who lives in a far less dusty suburb) gave me one as a gift, as it had been great for her 18th century farmhouse. I liked it so much at first that I immediately bought a second here on Amazon. They work very well, both as regular fans and as exhaust fans-- and you can also do both at once. Last week, we had several days hovering around 90 degrees Farenheit (32 Celsius), and though the fan's thermometer registered 88 degrees in my kitchen, with the fan on, it was just about pleasant. With the intake on high, I can feel the cooling air flow as far as 10 feet away. The fans aren't silent, but they make more of a white noise -- very consistent, no rattling -- and I stopped noticing almost immediately. This is really a good product. However.... They are getting dirtier by the day. Dirt accumulating on fan blades is unhealthy for everyone, but I also have the pleasure of dust and seasonal allergies, and it's starting to get noticeably uncomfortable to have the fans blowing in -- my eyes start to itch, and I get a bit of a cough. Both the fan in my kitchen and the other, which is in my living room overlooking a big, busy street, are now getting so dirty that I'm thinking that, unless I can figure out a hack for opening these fans up, I'll have to get rid of them. Anyway, I imagine that the accumulating dirt would kill the motors soon enough. I'll be honest -- when I got the fans, it did not occur to me check if the panels could be removed, as I've never owned a fan of any kind that couldn't be taken apart for cleaning. Had I noticed before the return period was up, I'd have returned the one I purchased here. What a weird, wasteful design flaw in an otherwise excellent product, and I'm finding plenty of complaints about it online. It boggles my mind that either the design team didn't anticipate that this would be a problem, or that the company simply doesn't care. Really: how hard would it be to reconfigure this? Another problem for those of us without the possibility of window screens: bugs get sucked in -- mosquitoes and flies are what we get most of here, and they definitely get pulled in with the air intake. I'm just glad we don't get palmetto or stink bugs here (yet). It would be great if there were an optional screen to fit on the back -- I'd happily pay for it. I've tried a variety of jury-rigged solutions, and the best I've come up with is cutting and sewing on a NaturalAire filter, which I bought here on Amazon. It definitely cuts down on the bugs and dust, but it's hardly an elegant solution. I can't help but roll my eyes at the time, money and effort that's gone into this fan. Update: What I've arrived at for cleaning is using my handheld shower to rinse off what I dirt I can, while doing my best not to get water near the motor. Then I let the fan dry for a day or two, just in case. It's slightly better than nothing, but it ain't the answer. I've kept the one in my kitchen, but replaced the one in my living room with an AC.
