System Noise Reducer

Cut the noise of the radon fan by about a third, but price was very reasonable

Worked wonders

We had a loud fan that I could hear through my bedroom window. I bought two of these and inserted them side by side in-line in the system. The noise reduction is very noticeable - it only went down from the high 30s to low 30s on my decibel reader, but the pitch is much lower so the noise is much more tolerable and now we barely notice it.

Fantastic quality item and a great price

Item was delivered very quickly, in good condition and well packaged. I will definitely use Festa Radon again !! Great customer service using the online chat feature to ask questions about this product!!!
