## Customer Reviews

### ⭐⭐⭐⭐⭐ Should have bought sooner
*by G***H on May 15, 2025*

Works GREAT in my basement window. Turns on and off as needed without my input.

### ⭐⭐⭐⭐⭐ Works great in basement!
*by R***. on August 8, 2024*

Our basement gets stale air. We installed in a window. When in use, we make sure to open a different window to get sufficient airflow for the fan to pull all the stale are out of the basement. We run it about an hour and the job is done! The pic shows right after install. We did finish by painting the wood and hiding the cord ;) We only turn it on as needed. Our main reason for purchase is we were getting a faint cat smell due to the litter boxes being in the basement with no air movement down there. This solved our problem!

### ⭐⭐⭐⭐ Exhaust fan
*by P***. on February 18, 2025*

They work really well, mounting is tricky in some applications but it's worth the time!
