VEVOR 24'' Exhaust Fan, Wall Mounted Attic Fan with Variable Speed, 3320 CFM, Automatic Shutter, Ventilation and Cooling, Silver, Fan Only

I'm renovating the bathroom, taking it to the studs, so the dust is extreme. But I just placed this fan in the window, perfect fit, and closed the window against it. It pulls all the dust out! Very powerful air flow but not too noisy. At the end of the day, the louvers drop and close it off from the heat and mosquitoes. Great!

Easy to install and works amazing. It draws the air from my shop better than I expected.

Exhaust fan works how it should, moves a ton of air, with the exception of its claim of variable speed. It sorta whines when it isn't at full power, doesn't really help reduce operating noise unfortunately. The shutters also clatter and bang when they catch the wind and the fan is off. This might be solved by building out a shroud around the front of the fan so the wind has a harder time lifting the shutters, but I haven't had the chance to test this. Overall, for the price, a solid buy. Don't expect silent operation. Gets docked a star for the variable speed performance.

This exhaust fan is well designed And works perfectly. When on you can barely hear the unit spin. I will definitely buy another one if needed.

We needed ventilation in our laundry room. This fan did the job. Works great.

Nice little fan, mounted in a 10-12 greenhouse. Runs quiet. Time will tell once I start using the greenhouse.

This fan worked perfectly right out of the box. It’s compact but surprisingly powerful—I used it in my kitchen, bedroom, and even out on the porch while working. It’s quiet enough to run without being distracting, and the airflow is strong for something this size. I loved how lightweight and easy it was to move from room to room, and the multiple speed settings were a nice bonus. Then came the incident… My curious little daughter decided it would be a good idea to see what happens when you stick a pair of scissors into a moving fan. Needless to say, it didn’t end well—for the fan or the scissors. Total destruction. But honestly, I can’t even blame the product. Up until that moment, it was doing exactly what it was supposed to and doing it well. If you don’t have small children with a flair for chaos, this fan will serve you very well. And if you do—just keep it on a high shelf! I’ll be buying a replacement because it really is a great little fan for the price.

Seriously moves some air. I rigged this into a bathroom window since my apartment doesn't have a proper vent system. It moves so much air I can vent specific rooms by just cracking a window in there and flipping it on in the bathroom, which is on the other side of the apartment. I routinely use it to clear the air in my kitchen which is around two corners.
