Review on VIVOSUN 8 Inch Noise 🔇 Reduction Silencer for Inline Duct Fan by Lisa Weigel

This is an affordable gear, it can be better right? will it cost more? Yes. I picked it for its price, and to see how well it works I have to admit that it lowers the DB level by a decent amount, but not to my satisfaction. The moving air will make noise. but if this reducer was longer it would be even better. I am happy with the purchase but I may look for a longer reducer in the future or build my own.
