  • Very quiet!
Size: 6''
It is very quiet. It measured 56 decibel at highest setting from 13’. However, it’s very hard to install as there aren’t any auxiliary brackets!

  • I didn't expect much and was still disappointed.
Size: 4''
Loud and weak, what more needs to be said, this fan would struggle to be effective in a 5' x 5' room, yet it sounds like a mini jet if you're with 5' of either vent.
