It’s loud but damn this works. I was demolition a bathroom with a black shirt and I barely had any dust on my shirt. If using in a bigger environment the noise won’t be too bad but in a regular size bathroom it’s very loud.
The versatility of this fan and the power make it such a asset in any water damage mitigation. Also with the PVC plastic tunnel allows you to direct flow in any angle and create a negative pressure environment.
This is the best fan I've ever had to supply more than enough air and quiet it also works as a great Little exsaust fan to remove toxic automotive exsaust fumes and paint plus dust
