Avalon Twin Window Fan with 9 Inch Blades, High Velocity Reversible AirFlow Fan, LED Indicator Lights Adjustable Thermostat & Max Cool Technology, ETL Certified by Avalon

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!"

Totally works. A marked temperature change in the room where I operated it in when it's in exhaust mode. Not sure why some reviews say it's too noisy. It's noise is about the same as a standard electric fan. It's great you can switch the mode of the two fans independently. One to exhaust and one to blow air. Perfect.

Un poco ruidoso pero mueve el aire bien.

This is a very effective fan for rural CT. It's always a good sign when the fan blades reach near the surround so there's not much gap and more draw through. Mine has been running continuously for a month since new on low. Noise is a little high but flow is also high for the low setting. The noise is bland, no problem for my sleeping nearby. Others may vary. I have it set up in a 1200 sq ft house with an AC wall mounted on the far end from the BR with the fan. It pulls cooled air through the house and out, even during the July 2023 heatwave in the northeast. The AC is only 6000 btus. It will also work well when nights are cooler to have open circ then close off as the day heats up.Left to right fit to my 1960s wiindows was fine. I had to patch some gaps around the expansion panels with weather stripping. Easy

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.
