I want to quiet down my central vacuum. I was thinking about either an intake muffler or an exhaust muffler (or both).

Will adding either of these impact the suction power of the vacuum?

I have an exhaust muffler on ours. Did not notice a loss of suction. It's basically just a larger diameter PVC with some foam inside.

now much noise reduction did you get?

did you make your own or buy one?

its a drastic reduction in noise. Ours is located in the garage, and when the vacuum is on, you can still have a conversation inside the garage. Compared to my parents with no muffler, you can hear the vacuum across the street, and not a chance you're hanging out in the garage when its on.

I picked one up from Vacuum Specialists

Need duals with 5” tips. This is Alberta after all.

Ours vents (now) outside and the noise difference is negligible from the muffler. Most of it is the vacuum motor itself.
