Great fan. I had a window fan of another brand that quit to do exchange air function after using it for a few years, so I finally decided to get a new one. That brand doesn't sell a fan that can control on/off by temperature, so I decided to try this Bionaire Window Fan with Reversible Airflow Blade with 3-speed settings. The remote control is a pleasant bonus! The fan is very loud on high setting, so I use low setting, but it works great and cools the room very fast at night. The caveat is while there is a turn down the light function, but it only affects the temperature display. The rest of the LED indicator lights are still very bright at night. Overall, I like the fan for its functions and features and how well it cools the room. Just wish the LED indicator can be turned down, so it won't be so bright at sleep time.

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.

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.

This fan is really good and is probably amazing if you have a horizontal window. Air flow is nice and cool, it can be loud but I don't mind that since I like the white noise. However, if you have a vertical window like I do, maybe think twice. No matter what I did, I couldn't get it to stop falling out of my window. It just wouldn't wedge in correctly and eventually the air flow would cause it to fall out, even if I had it going out one fan and in the other to try to balance it. Who knows, maybe it was just my window or maybe it was just me not being able to install it correctly, but I still figured it was worth warning about. Like I said, great fan while it works! Not so great when it falls out of the window 3 times a week and breaks itself into pieces, especially when it chooses the middle of the night to fall.

Great fan... Has all the features necessary and moves way more air than other similar fans. Remote is a nice touch - can change it from bed. Price seems in line with brands w/ lesser features. 2 small nit-picks: 1) There is a button that dims the display LED's; however, it doesn't dim that other "status" LED's... I can see someone who wants to sleep in pitch dark having to put tape over those lights. 2) When you switch between fan speeds or modes, it shuts off for a second, then spins to full speed for a second, then goes down to the right speed. Seems unnecessary. For years, I used the Holmes brand that had independent control and a mechanical thermostat dial... those were my favorites, but they stopped making them; The later digital versions didn't move as much air, but were the next best thing. This one moves way more air than either.

This review is for customer service more so than the fan. When it arrived, new out of the box, it made a loud clicking noise as if something was obstructing the fan blade, but inside the motor housing. Rather than ship the unit back to the retailer and get a refund (like I should have done), I called Bionaire directly because there's a large STOP! leaflet included in the box, which says not to call the retailer but to call the manufacturer if anything goes wrong. I'm not sure that this is the right approach for customers. The first customer service rep essentially said, "the unit is DEFECTIVE, cut off the cord and DISPOSE of the unit”, and Bionaire would ship us "an UPGRADED" unit. Sounds like a good deal, right? Wrong. A couple of weeks later, I received a package that had not one but two fans in it. One was a Holmes small tower fan that I had not ordered and didn't want, and the other was a Holmes window fan, that, while similar to the fan we bought, costs half as much, doesn't have a remote control, and has a 3-year rather than a 5-year warranty. When I called Bionaire (or rather, “Jarden Consumer Solutions”) customer service again, they said that I'd agreed to accept the Holmes fans as suitable compensation as they did not have our unit in stock. I explained that I was told only that I was getting an "upgrade", and if the lack of a remote control had been mentioned I wouldn't have accepted the switch. At this point the rep became...combative, and from this point treated me like a liar. It is a valid point that the third-party retailer had my money, so Bionaire couldn't provide a refund, but absolutely wrong that I agreed with plan that they specified which DESTROYED the rightfully purchased and DEFECTIVE fan, and saddled me with two useless-to-me, underperforming Holmes fans. Their potentially unscrupulous policies (…tell the customer they are getting an upgrade, and mark your report as “customer agrees to receive two under-performing fans to get them out of the warehouse”…) leave me with no merchandise with which to get a legitimate refund or replacement, the burden or returning two useless Holmes fans, and the pleasure of checking in with them every two weeks to see if they happen to be stocking the model I bought. Or, in short, it leaves me with $70 of nothing but hot, windless hassle, as I’m pretty sure the second rep, the so-called, and no-last-name “Jared”, knew very well that they will NEVER stock this unit, and they will NEVER fulfill my purchase, and NEVER make right the instruction to DESTROY the first fan. (Now that I think on it, that was certainly there simply to ensure that I couldn’t both get a replacement fan from them and return the defective fan to the retailer. Good one.) So, in the future and as a matter of principle I will avoid products from the Jarden family of products (Holmes, Sunbeam, Oster, Rival, Health-o-meter, Bionaire, Patton, Magic Chef, VillaWare, Crock Pot, Food Saver, etc). I will also return defective products to the retailer and get an immediate refund and ignore the manufacturer’s advice.

I am a big cheerleader for these fans! I have three that are the previous model (the old remotes still work with the new fans!). I have two in the new model. The new model looks sleeker and the remote is more compact. They are reliable and given me many years of use. One of the fans I’ve had for close to 15 years. It even managed a move across the country and has stayed functional! I like the three fan speeds and they are quieter and more efficient to run continuously vs a box fan. The temperature control is great so it doesn’t get too cold (or hot) when you’re out of the home or sleeping.

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.
