Seemed like it worked
I plugged this into my bathroom outlet since it was too loud to have in my bedroom. I could still hear it but I was able to block the sound out. Seemed like it removed odors and the air just seemed fresher but it kept falling out of the outlet so now I rarely use it. Maybe my outlets just can't hold something so large all the time, but anytime something would touch it - It would fall out.
