  When shopping for a window fan I set a budget of $100 or less. I wanted one that would last the longest and move the most air with the least noise possible. Long-lasting meant mechanical controls (not digital push buttons or remote controls) and air movement without noise meant the biggest blades possible. I shopped a lot and decided this was the one for me, and at a lot less than I expected to have to pay. I have the fan plugged into a Clapper outlet control (that's about 20 years old and works perfectly) so I can turn it on/off from bed if I want without a remote dying or getting lost or consuming expensive batteries. The Clapper Sound Activated On/Off Switch, 1 Each I've had this fan about a month now and I have no complaints. It makes as little fan/air noise as I think it reasonably can (and doesn't beep, I hate beeping appliances!) and moves as much air as I would expect for its size. It's weaker than a 20" box fan in terms of total airflow, but 2 x 8" fans = 16" and 16 < 20, so that makes sense. The thermostat works well. With a thermometer mounted on a nearby wall I've correlated thermostat knob position to approximate room temperature and it's entirely repeatable. The side extension adjustment has been mentioned negatively in other reviews but I had no issues with it. I measured my window, subtracted the fan + left-side extension's width, then extended the right-side as needed and locked that adjustment before inserting the fan into the window, then slid the left-side extension into place and set the whole assembly down and lowered the window on top of it. This fan has allowed me to not use my A/C so far this year when all my neighbors have theirs running daily...what more could I ask for? I have this set to exhaust in my bedroom window and two windows (all 3 the same size) open in the living room so air flows in from a shaded patio and it's perfect for me. I really feel this is the best window fan on the market that's <$100.

  I purchased two of these fans because they were priced well and being early fall in Texas, want a reprieve from the high ac bill. I used one to blow air out of a room that had an antique dresser we purchased that smells the holy hell of mold. We cannot get it out of the room due to its weight and size and have tried nearly everything to remove the smell. This fan turned backward will pull the air out of the room and can make any room fresh again! Did I mention setting the fan up is a breeze? See what I did there? Basically, the fan is ready to straight out of the box! It even comes with a free extention piece for wider windows like mine! My favorite feature is the fins for your window to help lock the fan into place. The fan can be a little loud on high if you are sitting or laying next to it. Just crank your TV volume up 4 to 5 notches to drown it out. I've found it works really well if you help create a cross breeze by using your fan and opening/cracking a window across the room. Another thing about that cross breeze- place your fan in the window in the direction of the breeze and not against for the best cooling and so you don't burn out your motor. Rain-they are waterproof. Mine ran through a thunderstorm and survived. They had an evaporator cooler effect. Not that I suggest unless your window is covered to keep the water out. Or maybe make your own evap cooler by placing a bucket/long pan of ice water in front of the fan...allowing the air to blow over the ice water. All-in-all I really like the two we purchased that we found a couple on clearance at Target this weekend and picked up two more! Then my sister used my portable mini carpet cleaner on her truck seats and tossed the fans into the truck windows to help dry the interior faster so she could get back on the road. Handy fans to have! P.S. I'm adding to say that I've used the fan in my crafting room while using epoxy (fan turned backward to draw the air out) and then turned forward on low while my cups were drying to help with the curing process.

  I will try to cover everything that I know, but I will say this from the start. Some of the info on the listing, is just wrong about the fans. My review is going to be a bit long too, because I am going to try an include the specs on the fan, so you know what they are, all in one place.

  First, if you, like me, prefer to buy made in the USA stuff, then let me say, this is NOT one of them. I bought this one because it said, "Origin: USA". I got them in, and found that both the box, and the fans, both say made in china on them.

  I got 2 of these, and found that they were not equal in the amount of power that they use. Since they have a surge of power when you first turn them on, I will give you the readings on them after they were running for about 30 seconds. Fan 1, then 2 respectively. High 49.7, 51.5 watts. Low 35.8, 34.9 watts. I am just letting you know not to expect an exact number, because each fan uses a different amount of power. I saw one person put that theirs uses 53 watts on high. So all you can get is an estimate on these.

  The power cord is an 18AWG cable, and is 5' or 5 foot long. It is just a standard, 2 plug end.

  The fan blades are around 6 1/2" wide, each. They are both made out of plastic. They do produce a good amount of air flow too. I would say, on low, it would probably be comparable to a standard window air conditioner's fan on high. It is hard to really give an accurate amount as things very too much, but it does give a good breeze, even on low. There is no information, anywhere on the fan, or in the manual, to tell what the CFM rating is for the air flow. I looked. Both fans also run together. There is no way to turn one off. It is all or nothing.

  The noise level of the fans is moderate. It is a typical fan sound, from the cutting of the blades into the air, type of sound. Basically the sound level is one that is plenty tolerable to be able to use it in a window, in say, a bedroom, or in a living room, and be able to watch TV at the same time. I would say that this fan on high, is probably about the noise level of my quieter window air conditions, just on fan, on low.. You do not hear much, if any noise, from the motors.

  They say that these are reversible, and the pictures make it look like there is a switch to do it. But, there is no switch. You have to manually turn the whole fan around to reverse the air flow. There is a switch on the top, on both sides, for you to control the speed, from high to low to off. They are not independent switches. There is one switch in the middle of the fan, and a plastic lever that extends to the outside of the fan on both sides.

  The fan size is 10" high, 21 3/4" long (about 3/4" of that is the lip to attach the side extension too), and that is with no side extensions in use. One side of the fan has an accordion type of extension, and the other side has a solid extension that slides down on that lip. It comes with one solid extension, but looks to be made so that you can attach multiple of them together, but I have found no way to buy more of them. Each side, the extensions come up to about 5" of extension per side, for a total of about 10" in extension, for a total width, or length of the fan, at around 31" max.

  It does come with a 1 year warranty too, just like is stated in the listing.

  The weight of the fan is pretty light too.. Maybe 2 pounds.. Not surprising since just about the whole fan is made out of plastic.

  I bought these to save on electric, so I can put them in the window, and turn them on at night, to pull the warmer air out of the house, and pull the cooler night air in, and then I just close the windows during the day. I would say it is worth it, vs running an air condition, when you take into consideration that these use around 50 watts on high, vs an air conditioner that uses over around 500 watts with just the fan, and well over 1000 watts when using the AC part of it too.

  I have only tested mine out so far, so if I have any problems, I will update. My opinion about it. I do like the fan, and I will get a lot of use out of them. I wish that they were made in the USA like they are advertised to be, and I wish I could have gotten some info about how much air flow they give off too. A switch to reverse the blades, instead of having to turn the whole fan around, would be nice too. But, for the most part, I am happy with them.. At least, so far. I took off one star due to false information on where they were made, and lack of info about air flow, noise levels, etc, without having to look through tons of customer reviews and questions.

  This is a great fan for my purposes. I live in an apartment with a gas range/oven and no outside exhaust fan. I was tired of smelling gas and fish and other smelly foods 3 days later so I bought this fan to exhaust the smells out when I cook. It does a good job. The fan itself is great, but I am short, so the only downside to consider is where you are putting the fan and if you can still reach to open the window behind it. My only kitchen window is above the kitchen sink so I have to get a step ladder to reach across the sink to open the window behind the fan and then to close it again. The fan blocks some of the light coming in but not a big deal. As you can see in the picture, it takes up about half of the lower window. Yesterday it was breezy outside and I had the window open but the fan was not running, and the breeze had the blades turning as if it was on.

  This fan did not come with a remote, but for kitchen use only, I didn't feel that was a deal breaker. It does have a control switch for each side and can be both intake, both exhaust, or one intake and one exhaust which is a very nice feature. Other fans I looked at were not reversible without physically taking the fan out and turning it around. I have not tested out the temperature switches since I'm using it strictly for exhaust purposes. My apartment has central air, so other than exhaust, I probably will not use the fan.

  The fan is not extremely loud. In fact, when I walk into the next room, I can hardly hear it running. The pullout section is OK and given the size of the fan is sufficient, but if the fan were any stronger, it would need something stronger to keep it from falling over.

  For the price and functionality, it is a very good fan. Just take it out of the box, position it in the window, plug it in, and turn it on.

  These are very basic little fans that work great. They don't have a lot of features, but they do have a high and a low setting. It also has the switch on both sides, so the fans are reversible. you can use them to pull air into the house or push air out. This has been very handy for me as anytime I cook a steak on the stove, there tends to be a lot of smoke. This fan has worked great to help push that smoke out, whatever smoke the over-the-oven fan doesn't capture.

  I originally bought two of these fans as our ac went out right in the middle of summer and we didn't have the means to get it repaired. So we wanted these at least for a temporary fix to help keep the kids' rooms cooler at night by pulling in some outside air (76 degree air is better than 85 degrees). The reversibility of the fans works great in that if you push the air out and open other windows throughout the house, it creates some good airflow that can help cool the entire house. This helped keep the house a little cooler throughout the day. Then at night we just flipped the fans around to bring air in and help cool the kids rooms.

  We also have sideways sliding windows so we use the fans standing on end in them and they work just fine. The cord comes out one end of the fan, but the fan is designed to allow the cord to come out without getting pinched or ruined by the window.

  We have really liked the value of these fans. They move a decent amount of air, they are inexpensive, they are reversible, and they are light and easy to move and manipulate. Great fans.

  The fan is not very powerful, even when both fans are running on high.

  I am a night owl who usually goes to bed at dawn, so drawing the cool night air into the apartment is very important to me. This fan does the job, but it takes hours to cool down the apartment. In my old apartment, I was using an old box fan, and that exchanged the air much faster. That box fan won't fit into the smaller windows of my new apartment, so I started exhausting air by pointing an old 16" oscillating table fan out the window (with the oscillator off, of course). That old table fan did a better job of moving out the air than this new dual-fan does. You might think that two 9" fans (18" total) would do a better job than one 16" fan, but it doesn't work that way. A 9" fan is very small and moves only a small amount of air, and pairing two of them doesn't make a huge difference. To cool off your home at night, you have to move air through it faster than the building is giving off heat.

  As an example, let's say that it is 80° inside your home and 70° outside. As this little fan exhausts hot air to the outside, it moves the air so slowly that the cooler air coming in through the other windows heats up quickly, and your home never becomes cool, even if you exhaust air all night. If, on the other hand, you have a box fan in your window, which would exhaust a much larger volume of air, then you will feel a breeze inside your home, and enough of that 70° air will get inside to make a real difference. This fan doesn't create a breeze.

  The most powerful choice for moving air is a high-velocity 18" fan, which can be bought on Amazon for $50 (not all of them will fit into a window, and they are noisy). The second most powerful option is a 20" box fan (also somewhat noisy). The third most powerful option is a 16" oscillating fan on high pointed out a window (not very noisy). This type of dual-fan is at the bottom of the list in terms of effectiveness. However, box fans are not made to withstand rain, which this kind of fan is, so that's something to consider. On the other hand, if you are smart, you won't leave the house with a big fan in the window anyway.

  Since buying this fan, I've discovered an advantage which a box fan doesn't have, which is that it can draw cold air IN without having to reverse the entire fan in the window. What I'm doing now is this: I have the fan mounted in my bedroom, and it exhausts air all night while I work in my office (without great effect, as I said). Then, about an hour before I go to bed, I set the two fans to blow IN -- that cools down the bedroom significantly before I hit the sack. If you go to bed at a more normal hour than I do (say, midnight instead of 5:00 a.m.), then it should still work. Set the fan to draw air IN about an hour before you go to bed, and then leave the fan on all night (on low) drawing cool air into your bedroom. The only way this won't work is if you live in a really hot area of the country where it doesn't get cool at night.

  I have owned a couple of these fans. I use it in the spare bedroom to help circulate air in the summer. I use one fan on "intake" and the other on "exhaust". I hope to create some sort of balanced circulation in the room. It works well and fits in the double hung window well.

  Not durable or weather-resistant as it should be

  I live in the sunniest city in the U.S. and have never had air conditioning here, so a window fan in the summer for my south and west-facing bedroom is essential in order to be able to function at home and sleep. This fan was mostly great when it worked, but here are the main factors and facts that lead me to give it an overall low rating:

  - I liked the idea of being able to have one fan blow hot air OUT while another drew cooler night air IN, but after testing it in various ways, that feature never seemed to make a noticeable positive impact. Unless you're needing a ventilation fan for working indoors with nauseous chemicals, this is a wasted, superfluous bell-and-whistle feature.

  - The thermostat feature was likewise great in theory - so it would turn off once getting to a certain temperature in the night, rather than continuing to blast icy air over me or whomever is in bed next to me until morning. However, it's so touchy that it would wake me up or annoy me for hours with the fan motor kicking on, then turning off, ad nauseum. I suspect this feature also leads to a shorter lifespan for the motor. What would likely be better is a simple timer I could set so it would go off at, say, 3am every night.

  - We don't get much precipitation here in Denver compared to other populous regions, but will occasionally get a sudden, intense rain or hail storm, usually lasting less than a full night. This fan is advertised as weather resistant, which is pretty darn important for what its job is. The window it sat in is also protected by an overhang from my roof, so it would only ever get wet if winds were blowing rain sideways into the south side of the building. And yet it completely stopped working after just two seasons. By contrast, my other main fan - a very basic little oscillating 12-inch round fan by Honeywell - has been running strong for 18 years now, even after being knocked over, falling while running, or being twisted in the not-right way countless times over the years. Other household fans in my family have lasted similar amounts of time. A fan motor encounters minimal resistance and, if made well, should have a MUCH longer life than this one did. Of course it's beyond the return window, but I'm very disappointed that I'm having to shop on Amazon for a replacement window fan so soon.
