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

It meets my simple needs. The wings/sides extend wide to fit my wide windows. Having a button to reverse the direction of airflow means I don't have to physically flip it. Thumbs up. It comes with stands that I'll never use when placing it in the window frame. Air flow is good. It's not noisy.

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.

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.

The Genesis Twin Fan is an excellent choice for efficiently circulating air in any room. Installation was a breeze, and within minutes, I had the fans up and running. One of the standout features is the ability to control each fan separately, allowing you to customize the airflow direction. Despite their impressive power, these fans operate with minimal noise, ensuring a peaceful environment. The reversible airflow function is incredibly handy, enabling you to expel stale air or draw in fresh air from outside, depending on your needs. However, it's worth noting that the packaging could have been better. The box arrived slightly damaged, but fortunately, the contents were intact. Overall, if you're looking for an effective and versatile fan solution, the Genesis Twin Fan is hard to beat. It efficiently exchanges air in the room, keeping the atmosphere fresh and comfortable. Highly recommended!"

Bought this fan for myself last year and was quite impressed with how well it worked. I have a small bedroom and it would make my room nice and cool and sometimes freezing cold. I didn't even have to put an a/c unit in my bedroom at all last year. I was so impressed with fan that I bought my parents one; they love it! The fans are big, which is a big plus. The duality of having one fan blow in and the other blow out is a major help. The noise level is not too bad, it's a fan, so it will make noise, but you get used it like any oscillating fan. The light on the fan is a little bright, but a simple cover up of tape takes care of that. Pulling out the sides is a bit tricky, however, and a little troublesome. There was one time when one fan stopped working; I read the reviews about this and worried that the fan was broken like everyone else. Luckily, the fan was just stuck. I was able to stick a piece of paper through and help the fan turn again and it's been great ever since. Overall I am very pleased with this fan.

Un poco ruidoso pero mueve el aire bien.

As the headline suggests, this is not a quiet fan. however, if you want a fan that does the job and don't mind that it needs to make a noise to do it, then this fan is for you. It works really well and the option to change the direction of the air is great. I have used this to bring cooler air in from outside and to move hot air out from inside. Overall, this is a good fan.

First impressions are good. I bought this to ventilate my room while I 3D resin print. Although my 3D machine has a built in ventilation tube (as shown in pictures), the room still builds up fumes when printing, while i’m cleaning the prints and when I haven’t poured out the resin into it’s containers. This fan works great as it can suck out air in the room. I will eventually make use of it during the summer if rooms need to be cooled, since it works well with bringing in air from outside. The design could be tweaked, very minor but I wish that the temperature on the fan was displayed in Celsius too, only Fahrenheit temperatures are shown. I especially liked how it fits vertical and the extenders stretches enough to fit snug on my windows. In the pictures I have to make room at the bottom for the ventilation tube for my 3D printer, but the fan does stretch all the way down. As for sound, it’s comparable to a normal fan even on high.

Got my fan today in preparation for summer and installed it into my window. The accordion wing 'tabs' that lock it are very difficult to open, I had to pry them to expand the wings to fit the window but it fits great. The second issue I noticed as I turned it on (low setting) was that it is extremely loud. I put it down to the 'turbo velocity' in the description?! I don't know, I'm not in any way an expert on what size motor runs what and the expected decibels would be. But I have purchased and used a lot of these types of fans in the past because I do not have air conditioning to rely on to stay cool during the hot summer months. I have tried Bionaire and Comfort Zone window fans, and they are quieter running on 'high' than this fan is running on 'low'. I chose this fan because of the price difference, this one was cheaper by about 30-80$ than the others that I was looking at. On the good side...I have noticed that this fan pushes much more air than previous ones I've used. It is more powerful. I have a large living room and can feel that it is much cooler in here after 15 minutes of use on the low setting in exhaust mode. It works in all functions and the buttons seem sturdy as this one does not have a remote. The colour is a bright white which looks nice in the window and fits in place even with my screen still in; so no bugs. So if you need it in an area where you won't be sitting right beside it like me, I would recommend this purchase as it does as it is supposed to very efficiently.

Love this fan. Much better than other models on the market. It's quiet compared to others. It has reversible blades to suck out the heat during the day and just a touch of a switch it blows in cool air in the evening. Who needs an air conditioner when you have this. It runs at different speeds and even can be set at temperature needed then will turn off when the desired temperature is met. I tried others but this one out does others on the market. Well worth the price.
