Rated 4.2 out of 5 by 346 reviewers.
Rated 4.0 out of 5.0 by Great Product, Would Purchase Again, Better than Competing Products Context: We use the fan to cool our living space in the evening and night during the summer. Features: 1. The unit was far better than we expected in terms of build quality and function. 2. We were so pleased with the extra window closure panel that extended the range of the built in, adjustable width/ height adapter. 3. The speed adjustments, reversing of the fan rotation direction with a switch and bi-directionality (one exhausting while other was blowing inward) are great. While the thermostat function allows one to set a trigger level for the fan operation, a feature that we don't use since in the day temperatures can be over one-hundred Fahrenheit and leaving the fan in the window would not be sensible because the incoming air through the fan openings would heat up our living space beyond the comfort level. More About How We Use The Product - by way of explaining why we wanted it and our evaluation What we do is wait until the evening, outdoor air is equal to the indoor temperature, then we open the window, install the fan, set the speed to max exhaust speed through our living room window and then open our bedroom window to cool our bedroom first and then more slowly the living room since the bedroom air coming through is warmed by the bedroom itself before reaching the living room. We get as high as a twenty degree differential between the indoor and outdoor temperature during the day by shutting off the fan in the morning when the indoor/ outdoor temperature differential is zero (same level) and we remove the fan and close the window until evening when we begin the cycle all over again. Installation Considerations - Our Experience with the type of window in our house For our use, where we have sliding, wood framed, thermopane windows, where the depth of the window assembly is less than four inches from inside to outside, the fan body depth exceeds space between window sash and the window screen, so the fan unit cannot be installed with the screen in place. Not wanting to remove the screen, we built a wood frame surround (box) to mount the fan offset, away from the screen. The window now closes against the frame and small wood blocks on the outside of the frame lock into the window groove to keep the fan from toppling out of position and falling. See Installation Photo Tuning Up Fan Performance Now a word about the fans power - air moving ability. We noticed that the unit was not able to match the air flow of our small, 40 watt box fan which we bought in Malaysia while traveling, and we use around the house via a 220 volt travel adapter. It was this fan that we were replacing for window use. We were incredulous that our new twin fan unit could not keep up with our old mini-box fan. So we measured the fan face diameters for the new unit and the old one: the new is twin 9 inch diameter fans and the old was only 12 inches (we brought this diminutive baby home in our suitcase). Actually the new fans have more square inches of flow area than the old 12 mini-box fan (pi r squared x two fans vs pi r squared for the single fan). So, why the poorer performance. And then we noticed that, while the new twin fans had nice aerodynamic blades, they were something like 10 decibels more noisy. Then we took a closer look through the grille of the new fans: They start off great with a ducted fan design, so why the noise and lower performance??? Closer examination shows a real boo boo on the exit path for the fan air: The air exits the fan into a non ducted cavity and the air path is not aligned with the fan axis. Not only that, but the exit grille is not circular, not aligned and smaller in area than the fan face diameter: naughty, naughty. This causes turbulence, loss of efficiency (lower performance) and noise generation. We love this new fan pair though and the manufacturer almost got it right . . . so we just inscribed exit circles on the exit side of the case in a larger diameter, but aligned with the fan axis and cut the plastic away with a utility knife. We then took a bit of aluminum sheeting from a dryer vent (purchased from Home Depot) and completed the original plastic duct to conduct the air smoothly to exit the case. Since the fan exit faces the window screen in use, we did not make a new exit grille. Wow, now the noise is reduced and the fan efficiency has increased majorly so we equal or exceed the old mini- box fan. Our house is cool all day - see above technique description - and we are very happy with this fan unit, even though there were some practical issues in both fitting it into our average, normal wood framed sliding window and in the poor fan exit path design. All in all, a great unit and it works well even though the manufacturer missed it a little it was retrievable: We would recommend the fan over similar designs that really have less features and function.

Rated 5.0 out of 5.0 by it's been workin' for 5 years This thing has been running for 5 years so far. Still looks & works like new. I have it in my garage, which I turned into a poker room and my buddies all smoke cigars & cigarettes. You can see the smoke just pour out the window. Both fans are sucking out of course. You can actually feel the draft coming from the gaps in the garage doors, so it has good suction and draft. Overall, this little piece of plastic cranks!!! I had to modify above with a perfectly cut piece of cardboard in the area that the fan doesn't cover, which helps a lot too. When it rains, I take it out of the window. March 6, 2014
Rated 5.0 out of 5.0 by EXACTLY what I was looking for. Incredible value - I wish I'd bought these fans years ago! They are extremely quiet and efficient. Without moving the unit, you can set the fans to blow in or out, or turn one of them off, or set up exchange (one in and one out); there is also a thermostat so the fans shut off on their own. I put one in my office and one in my kitchen (the kitchen window is just a smidgen too small, so the fan is at a very slight angle, but it's in there securely and works just fine). June 4, 2014
Rated 5.0 out of 5.0 by This product really works One of my daughters asked me to buy a fan for her and for no reason,I bought this one (the first I bought) and gave it to her,few days later,we were talking about how hot it was and she told me that her apartment was very cool because of the fan,she said I should buy one,instead i bought 3 more,one for me and my wife,one for my other daughter;s place and one for my son's bedroom,I'm really happy with this fans performance,it removes heat during the day,and at night,we reverse it and it brings coolness to inside our bedroom and it looks nice too!!!!!!!

Rated 5.0 out of 5.0 by Works great all locations We added a family room onto our mobile home and needed to move air from the main house to the new room; solution was these window fans in the existing main house windows. They were easy to install, quiet to operate and the price was right. The versatile operation (in, out or both) is the perfect solution for our air movement. We even added one to the work shop window.

Rated 5.0 out of 5.0 by Suits my needs perfectly I live in a one-bedroom apartment that has all the windows facing north, so there is no natural cross-ventilation. I needed something that would draw in fresh air from outside, and this item is perfect for my needs. I set the fan in a living room window. During the day, I draw air into the living room; at night, I reverse the fans, and it gently draws cool night air into my bedroom; what noise there is from the fans stays in the living room. The choice of three speeds and two reversible fans gives lots of options for the amount of air movement desired. I don't really have much need for the thermostat, but it may yet come in handy at some point. The apartment does have an in-the-wall air conditioner, which I will use when it gets really hot. So far in late May and early June 2013 since I bought this fan, I have not needed the A/C. The fan has met my needs, functioned well, uses less energy than the A/C and is a lot quieter. Since I've only had the fan for a short time, I can't evaluate things like durability yet. Time will tell. June 11, 2013
Rated 5.0 out of 5.0 by 9 Inch Twin Window Fan I purchased the 9 Inch Twin Window Fan to help vent out cooking odors out of my kitchen. I have one of those microwaves that vent the odors through a filter then back into my kitchen. It takes me less than 30 seconds to set up. The fan helps out a lot. I do leave it on when I cook and then about 15 minutes to 30 mintues after cooking. It does have extensions on the end to help the fan fit your window. One is fixed the other adjusts. It's made of plastic so I can see it breaking if not careful. The fan is quiet. Has 3 levels, low, medium and high. Has an in and out switch. Also a thermostat. I've only used the fan to vent out air not blow air in. I purchased the fan duing the winter (off season). I had to try 3 different Home Depots before I could get one. I used the internet Home Depot because once you order it lets you know in about 5 minutes if it's in stock ot not in stock. Home Depot even calls you. They show how many they have in stock at the Home Depot you choose but the counts not very accurate. The first Home Depot I tried showed 3 in stock but it came back nothing. The second Home Depot I tried showed about 10 but it came back nothing in stock. The thrid Home Depot showed around 8 left and they had it. The first 2 Home Depots that called me I did let them know what the internet count showed me. January 15, 2013
Rated 3.0 out of 5.0 by Twin Window Fan I use this fan in our bedroom and a window mounted air conditioner in the adjacent living room. The fan helps push warmer air outside while simultaneously pulling cool air in. It seems to do an okay job but I imagine a more powerful fan would work better. Overall, for the price, it works well enough. July 5, 2015
