When I read reviews, I noticed mixed comments about noise levels. Personally, I found it to be relatively quiet on the lower settings, which was a huge plus for me, especially when I was sleeping or watching TV. However, on the highest setting, it can be a bit louder, so keep that in mind if you’re sensitive to noise.
