Genesis Twin Fan High Velocity Reversible AirFlow Fan, LED Indicator Lights Adjustable Thermostat & Max Cool Technology, ETL Certified, White (A1WINDOWFAN)

This fan is a little noisy on high, but I like falling asleep to the humming noise. You do not have to switch the whole fan around to pull air out out of the room. You just hit a couple buttons at the bottom and it will reverse. Very good cooling performance, it really does a nice job of cooling down a room quickly. I definitely recommend this fan.

This fan is great! We especially like that it comes with attachments so that it can be put on a level surface when it's not in a window. The reversable air flow works really well to pull out hot air when needed. It's very quiet, unlike our other one and has different speed settings with an adjustable thermostat. Sometimes our bedroom gets a little warm at the end of the day, so we turn on the fan a couple of hours before bedtime so that the room is cool. It's perfect for those days when we don't turn on the central air.

I moved into a new place where its harder to step outside to smoke, as I will make a lot of noise climbing down stairs disturbing the family below. As a result I started smoking in my room and required a powerful exhaust for ventilation . I already had a pretty good exhaust fan from a brand called Duracraft (have a small table fan from the company too) , not really sure how I cam to own the thing but it worked like a charm and had enough functions to make it flexible to switch each blade manually in or out and each with its own power setting. Thing worked like a charm and kept the room fresh untill recently something knocked loose and seems to create a loud unpleasant squeal in one of the fans. lacking the tools and time for repairs I found a quick replacement from a dollar store. The $30 POS Comfort Zone replacement was a complete disappointment, not only it was completely featureless but the one thing it was to do it was quite weak at doing. And since sun has been invading the earth as of late, I have invested in an AC but cannot get rid of the pockets of stale smoke from the room. As a result I found myself on Amazon looking for another replacement from Duracraft. Either the company shut down or got bought out a while back since I could not find anything. The next best thing was this model being promoted on Amazon top picks and all accounts seem to confirm it at least is powerful enough to create good suction. I have had it for almost a week now and I can confirm it is a worthy replacement. Its remarkably silent on its highest settings and walking in to the room after work feels quite fresh. However, I do have to admit for the price I paid, I was a bit disappointed with the lack of options and flexibility as my beloved Duracraft. Not only can you not control speeds of individual fan, you cannot move the vents around to direct airflow. The knobs that switch the direction of the airflow feels a little brittle. I get the feeling fiddling with those things too often will result in the plastic knobs breaking in my hands. The thermostat is alright but not much useful for me as I just like to keep the thing on full blast on cool nights and open the adjacent window to let some fresh cool air in like tonight as I am typing this. The biggest thing is that the fan actually makes a electrical hum on lower speeds. Its almost as if the motor has to force itself to slow down. Like pushing the breaks on full throttle. None of this is a deal breaker as I mostly use it to push out smoke and stale air from the room so as long as it does the one thing it can do I can bear with the lack of options. I donated the 30 dollar replacement to the family downstairs as they have a habit of setting off the alarm when they cook. I was thinking about trashing the older model but this particular made me appreciate the option my Duracraft allowed me so I am thinking of cleaning it up and taking it to a repair store to get it fix so I can have two fans on each window for excellent airflow on cooler days when the AC is removed.

Well you know, oddly enough I never got around to using the Genesis Twin Fan High Velocity until today, late in the summer of '26... several months after I ordered it. Frankly my expectations were not high. I wanted a large window fan and none were available for the money I was willing to part with. So the Genesis Twin Fan High Velocity sat around in the box for most of my scorching Alabama summer....and I finally put it in the window where it sat some more. Today, long story short, that thing really pushes air! Most impressive....and for the pittance I paid for it. Wow!!! I can see now why the ratings run high on this thing. Get one for Most High Number One Happy!

Bought one at a garage sale. LOVED it so much-- we ordered a second from Amazon. Easy to install, fan choices are in/out, it kicks on reliably according to your temp setting. When it's in high speed setting it is quiet and gets the air moving in a small room. Highly recommend. We are considering buying a third!

I simply cannot understand how someone designing a product that may be used in a consumer's bedroom could decide to install indicator lights that light up an entire room. The lights on this fan are too bright, but this is an easy fix with some electrical or other opaque tape. That is my one gripe. This fan is quiet when it comes to fan noise. I prefer a bit of white noise while I sleep, and this provides it. I would not rate this as a noisy fan, but instead an acceptable level of fan noise. Even for a bedroom. If you need a quiet fan, this one might work for you. That said. It's certainly not silent. The in/out feature of this style of fan is very powerful. I have a small room with a single window, so creating a draft with the door closed is impossible. With the fan I am able to circulate the air in the room. The room feels cool and fresh even on a hot summer day. I had been using the A/C frequently, but since i had gotten the fan I have used the A/C twice. When it's around 95 degrees or warmer out I find I need the A/C. Otherwise, the fan does enough work! I haven't tested out the temperature feature just yet, as I prefer the fan always on for the white noise. This model did not arrive with a remote if I recall correctly. I wouldn't have used one anyhow. Overall, this is just an effective fan. Would recommend. Especially excellent for horizontal sliding windows as you can stand the fan up on its side. There are instructions with the fan as to what I mean if this is a new idea for you. Would buy again.

Moves a good amount of air, better than the budget fan we bought alongside it. The simple switches to go from blowing air in to exhausting air out and ability to control each fan independently that way is very nice for venting a small room. This fan is unfortunately loud. The real problem with this fan is at the two lower speeds the fan has always made an electrical white noise/buzz behind the sounds of the fan that is admittedly very off-putting to everybody who's ever encountered the fan. At full blast sound is comparable to our 20" Lasko fan on the lowest setting, however a 20" box fan moves a significantly larger volume of air. We bought it two years ago, and it's still working but starting to show signs of the slow down death spiral. Given we have two very shaggy dogs that's average fan lifespan for our house, nothing great but no red flag.

I wanted a decent window fan for the fall and especially the spring to draw the cool air in at night when there is no breeze. I have only used this fan a few times, but it seems to be doing that job so far. I have enjoyed using the temperature settings so that my room doesn’t get too cold at night. I have noticed that if I set the temperature to 60 degrees, it really means 65. In my video, you can see when I use the temperature settings, the fan runs at 60 and shuts off at 65 even though the temperature in the room was about 67. I also noticed that the fan shut off one night when I had it set to 60 but the room temperature was about 67, and I think it was because it was so cold outside at 30 degrees. I imagine the fan can’t read the temperature inside the room when it is significantly colder on the windowsill where it sits. I don’t really mind this discrepancy, though, because I like my room close to 65 degrees at night, and I can still achieve this so far by setting the temperature at 60. I love that it is so easy to change the direction of each individual fan with the flip of a switch, as you can see in my video, and I have been running it with one fan blowing in and one blowing out. I personally don’t find the noise from the fan irritating, though to be fair, I have another fan in the room that drowns out the noise of this fan somewhat. It isn’t the most powerful fan by any means, but for a smallish window fan, I think it has decent power, enough that it has affected the temperature of my room. As other reviewers have made clear, this fan does not come with a remote, and while that would be a lovely perk, I won’t count it against the fan since it was not promised to me and it is not a necessity for my needs. I am happy so far. Based on reviews of these double window fans in general, I am a bit worried about durability, so if this fan stops working in some way or otherwise disappoints, I will try to return to edit my review.

Un poco ruidoso pero mueve el aire bien.

I love how you can make the fans blow opposite directions. I have 2 windows in my room for air flow but the one window is pointing towards the main road and it’s spot noisy. If I don’t have it open the air in my room gets stain and it’s super hot. But with this fan I close that window and put the fan in the other window and have the fans working in opposite directions and it keeps the air moving and it’s cool in here. Better than it’s ever been. However $86 is a bit pricey for a window fan. I bought one of these from Walmart like 10 years ago and it was like $20. Im just hoping I get at least ten years out of this one given the price.

Love this fan. Quiet enough to sleep in the room while it's on. About the same amount of noise as a regular stand up fan. Cools the room quickly if you keep the door closed and the curtains shut to block out the sunlight. Almost as good as an air conditioner. I put it on when I left for work at 1pm and when I got home at 11pm my kitchen was sweltering but when I walked into my bedroom, it was nice and cool. I love that the fans are automatically reversible to blow air out if you want and they are independently controlled so you can have one blowing in, one blowing out if that's your thing. You don't need to remove it from the window to turn it around. You don't have to remove this fan from your window all summer if you don't want to!

If you are looking to rapidly flush warm air out of a bedroom or pull in crisp evening drafts without sacrificing floor space, this 9-inch dual-motor window fan is an incredibly versatile choice. It is best suited for those who need active, independent temperature control and can handle a louder, high-velocity operational hum. The Good & The Bad: •Pro: Reversible blades allow one motor to intake fresh air while the other simultaneously exhausts stale air. •Pro: Built-in thermostat ranges from 60 to 80°F with highly visible LED indicator tracking lights. •Pro: Expandable side panels pull out an extra 6.5 inches on either side for a seamless window fit. •Con: The high-velocity dual copper motors generate a loud, prominent roar even on the lowest speed setting. •Con: The mechanical control layout relies on standard push buttons rather than an included remote control. Full Performance Breakdown: •First Impressions: The unit arrives tightly packaged and features a durable, rigid plastic frame that weighs roughly 3.8 kg. It includes two removable snap-on legs, allowing you to quickly transition it from a secure window mount to a freestanding layout on a desk or floor. A slick, hidden carry handle is molded directly into the back panel for effortless portability. •Real-World Testing: The Max Cool technology performs excellently; the built-in thermostat reads indoor temperatures accurately and cycles the fan to maintain your preferred comfort tier. Air circulation is remarkably strong, driven by independent, weather-resistant copper motors built to handle humid window environments. The simultaneous intake/exhaust functionality is a massive win for bedrooms, instantly cutting down room stuffiness without requiring you to physically flip the entire housing around. However, the airflow velocity is so intense that the acoustic output is highly noticeable—if you are an incredibly light sleeper who requires a silent room, the low-frequency motor noise might be disruptive. •Maintenance & Longevity: The expandable locking panels stretch smoothly to fit window frames up to 37 inches wide without leaving open gaps for bugs to slip through. The entire unit carries an ETL safety certification for long-term electrical peace of mind.

Great fan . Works so good I bought a second one . One for bedroom and one for the living room . We rarely use our are air-conditioning now that we have 2. Easy to put in the window and take out for the really hot days we need to put our air-conditioning in the window. But even on those days I'll take the air-conditioning out at night and put the fan back in the window and our place is so cool when we wake up and we'llwe sleep. Great buy .would highly recommend. As for people saying it's loud I personally don't think so . Not as load as having air-conditioning on or some other fans . Also it's a fan it's going to have a sound to it .
