Review on VIVOSUN 8 Inch Noise 🔇 Reduction Silencer for Inline Duct Fan by Tina Cruz

Installed on my 8" duct coming from an attic fan I use to suck smoke out of my smoking room. Others have commented that the fan noise is annoying and that solved the problem pretty well. This unit was cheaper than any I found online and appears to be almost half as quiet as it was before installing it. Note the size, this thing is BIG and not very light, but it works so I have no problem with it!
