Bionaire Thin Window Fan with Manual Controls(BWF0502M-WM)

Great window fan! I don't know why I never posted a review for this product, but it is fantastic. This little jewel kept my bedroom cool when my house was registering temps of 85 to 90 degrees - a lot of nights to the point of being downright cold, but I'm ok with that. I sleep better when my bedroom is cold. I could set the thermostat to whatever temp I want and it kicked on and off to maintain that temperature, it is amazingly quiet given its function, it is easy to install, easy to operate, and it kept performing all night every night for 8 years of service during the summers. Sadly, it croaked last week, so I'm going to have to find a replacement. I'm pretty sure I didn't pay $62 for it, though, nor am I paying $62 to replace it.

I've had this for a year, so I wanted to give my thoughts- though, really, it's only the one:Get this.I was recommended it through a Reddit forum, and the 5 stars it's been given is absolutely earned. This little beast has gotten our 100yo house down to 65 degrees on 90 degree days. In the photo, we have it on auto-run, so it measures the temperature you set and runs when it gets more than 6 degress above it. You can set it to run low, medium, or high, and we've really only ever needed the high setting on the most humid of days.It's fantastic. Can't stress that enough.When the breeze picks up, the fans are loose enough that they'll move a bit, but honestly that's a feature, not a bug.We've run it in the rain, heat, humid- whatever. It doesn't quit.Small con: It really needs to be pointed in a centeral direction to cool the space evenly. We're lucky that it's the only window pointing straight down the room, so from the moment you walk up, you feel it. Any bigger of a room, you might not feel a huge difference.Another small thing is that it doesn't fit *entirely* flush, so if you don't have a screen on the window, I wouldn't recommend it. Sides are perfect, but along the top it has a slight rounded head.If this thing ever dies, I'll be buying the exact same model.

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.
