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.

The A1 Window Fan from Genesis arrived double boxed. There was not packaging between the two boxes like for high end electronics, instead the internal box is glossy, color print suitable for retail sale. Still, my outer box had a gouge where the inner box did not, job done. The outer box is also detailed with product information, to help porch pirates. Surprisingly, all of the product information was clearly written by a native English-speaker, which is when I noticed the business is owned by someone in the US (since it wasn't considered in my purchase decision). There were Styrofoam inserts to keep the fan from the sides of the inner box. The fan itself has two accordion style expansion panels, but no rigid piece for horizontally opening windows. I had read that someone used this fan with window screens, but my screen is too close to the window to insert it in the sash. I am not going to remove my window screen for it, so I attached the feet and set it on my window sill. The power is a button, not a switch, so it cannot be controlled by a smart outlet. This is a major strike for me, but I don't count it against the rating. For the dual window fans of this type, the only ones with physical switches have one-way motors that don't allow for circulate mode and require you to physically flip the fan to reverse air flow. I might have been better served by one of those, but I didn't think it was worth returning this one. I also considered smart fans, but they all seemed to have other negatives in the reviews. This fan has physical switches to reverse the direction of each fan independently and they work well even when the fan is on (thank you Nikola!). You repeatedly press the power button to clocked between hi, med, low, and off. Each speed (except off) is indicated by a bright red LED. Better than blue LEDs for a bedroom but still a bummer. They are somewhat recessed if you want to cover them, but I'm not worried about it, since there is a lot of light from my window when the blinds are open anyway. I don't use the thermostat control, so I can't speak to the accuracy of the temperature but it is another button and bright green LEDs indicate the selected temperature when it is engaged. It seems to work fine (fan turns off when temperature is below the selection and fan runs at high speed when the temp is higher than selected). The fan noise is as expected, since smaller blades need to operate at high RPMs. I would have done with the low and medium speeds operating at slightly lower RPMs though. I leave it at high until bedtime when I switch it to low, and I can still hear my alarm in the morning. So it is not a perfect fan for me, but that fan doesn't seem to exist and the quality of this one is good enough that I will adapt.

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.

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!

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 am really happy with this. It fits perfectly in my window, and on low speed it isn't any noisier than the box fan I was using. One thing to note is that if you're using it in a window, DO NOT put the feet on it.

Un poco ruidoso pero mueve el aire bien.

First off, I waited a while to receive the item. It was stated nowhere that this was a US item, I live in the UK. So I had to buy an adapter. Time comes to finally use it, and let me tell you, the sound on this thing is ATROCIOUS. You can barely even hear your own words on the LOWEST setting. The medium and high settings make literally ZERO difference to the speed and sound. What is the point of having them? Let me say, you absolutely cannot use this in a place like a bedroom, it's incredib Thly loud and there is nothing you can do about it. Is it really that hard to have an actual low setting? The video I've provided doesn't justify how loud this thing really is, due to one of the fans being dead. If that wasn't a bad experience already, it only got worse from there. Both of the fans died on me, not even within 10 MINUTES of me testing out the fan. You can see in the video I've provided that one of the fans just die, randomly. I've tried and tried and I cannot get them to come back on. The LEDs still light up, but the fans are completely busted. What a waste of time and money.

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!

So far so good, for now. Moves air well, fits well in window, does produce a noise from the motor that remains no matter the speed, would place it midrange loud for similar products. If air movement is priority and sound is second this wins, but if you're noise sensitive may want to pay more for the models that move air as well but have more quiet motors. Prevents from having to turn on the AC in all but the most humid days, but you will have to increase the volume on whatever you're listening to to not hear it. The only other issue I've encountered is the 2nd one I bought for the kitchen seems to vary in speed every few minutes, hopefully not an electronic issue that will shorten it's life; so far been running 24/7 for 3 months.
