9 Blades Twin Window Fan with Reversible Airflow, Remote Control, 3 Speeds, 3 Functions, Bathroom Kitchen Exhaust Fan, Width Adjustable (From 23.5 to 37) ETL Certified Small Window Fan

It is a very nice fan. It is expandable to fit various size of windows. I actually measured how wide it can expand and I found that it can expand up to 37 inch. Very impressive size and when it is fully folded it is 23.5 inch. I have many windows ranging within this range. I can move from one window to another without an issue because it is very light and portable. I believe most windows are within this range. The package also includes a remote control so that I can control it from afar. There are 3 speed mode from low medium to high.

I got the fans in 3 days and installed them in my windows quickly and easily. My a/c had broken down in the worst heat two days before. These fans got the air moving in and out of the house. The fans have 3 functions: cool, exhaust the heat outside, and act as an air conditioner. I have two perches for my cats and they sit on them close to the fans. They love it. I am very pleased with the fans and there is no loud noise while they are running.! I am planning on buying two more for my back rooms. Thanks so much!!!!!

VERY QUIET , GREAT EXHAUST

Questionable quality. Vibrates badly on all 3 speeds

Could be a little more powerful all else great

Exceeds my expectations but the constant hum might be a deal-breaker for some.

The fan is bigger than expected. I bought this because my old window fan quit working after almost a decade. This one is significantly louder than my old one. It also barely has any airflow. I expected a lot more considering how big the blades are. Also, the led lights are much brighter than they appear in the photos. Overall Im not happy.

So I wasn’t sure what to expect, but the install couldn’t be easier-nothing extra needed and they throw more cool air than expected. Able to sleep at night again!

Love that it allows for intake and outtake.

A little loud on high, but moves a lot of air for such a small unit.
