Not only does the muffler greatly reduce the motor noise but it also effectively suppresses/diffuses the exhaust coming out of the vacuum. Previously, if I was vacuuming in an area with lots of dust or loose materials I had to be mindful of where the exhaust port was aimed or I'd make a bigger mess than the one I was trying to clean up. The muffler quiets the machine and keeps the mess going where it's supposed to - INTO the vacuum.
This does work and is needed on vacuum. However, it should be included with the vacuum itself as it to prevent huge "dust storm" from unit exhaust if not used. It is an add-on cost that should not be required.
I didn't even know they called this a muffler. I looked for it as an exhaust filter. It replaces the old sock that I had to use after buying my 12 gal vacuum. This item should really be a part of the accessories in the box but unfortunately we have to buy this as a side item. On the plus side, it comes with several adapters so it should fit the entire RIDGID line of wet/dry vacuums. Once installed, you'll likely never take it off except for the occasional rinse and clean.
Pros: Lots of Features, Sturdy, High Quality, Easy to Install, Good Size & Weight
I purchase this unit with the Ridgid WD4070 because my last shop vac (15 yrs old) spit out dust from the exhaust port, which is not good when detailing vehicles. I also wanted to muffle the exhaust a bit. I measured the sound level of my unit using a sound meter (at 3’) and the exhaust was 91db without the muffler and 83 db with the muffler. So, while it will not reduce the sound by ½ as someone mention here, it does reduce the sound as advertised. Note: The packaged does not say how much it reduces sound, but that it reduces the sound, so it works as advertised. I wonder how many of the reviewers that said there was no reduction in sound actually measured the sound levels. Oh, it does block the tool storage a bit. I am satisfied and glad I purchased this unit because it reduced sound levels and keeps dust from flying all over the place, which defeats the purpose of vacuuming.
Pros: Easy to Clean, Easy to Use, Sturdy, Easy to Install, Good Size & Weight, Nice Design
IT WORKS AS DESCRIBED AND DOES A GOOD JOB!!! THE ONLY THING THAT IS BAD ABOUT IT IS THAT THE COUPLER THAT IS NECESSARY TO ATTACH THE MUFFLER TO THE VAC OUTLET MAKES THE MUFFLET STICK OUT TOO LONG. ITS TOO BAD IT WASN'T A LITTLE SHORTER OR CLOSER TO THE VAC SO YOU WON'T CATCH IT ON THINGS AS THE VAC IS PULLED AROUND YOUR JOBSITE.
I added this to my RIDGID 4-Gallon Wet/Dry Vac model WD4070. You can hear a difference. Used a digital sound level meter from 3' and measured 91 dB without the muffler and 88 dB with the muffler in place. It does intrude a bit on the tool storage pocket's capacity. I don't have a way of measuring any loss of suction power but can't imagine there would be any comparing the effects of the 3-ply dust filter with this open cell diffusor. So, yes, it does technically reduce the noise. Overall the quality matches the RIDGID vac including the locking clip. The adapter isn't needed for the WD4070.
I notice a difference in the sound. Not huge though. Its noticeable, but not a lot. Even with the muffler, the shop vac is still very loud. I like having it on my shop vac because I work in peoples homes, and it reduces the noise slightly on my shop vac. If you are buying this to make you shop vac super quiet, then don't, because it wont. For the price, I think its worth it to reduce the noise slightly. Hope this helps.
...I didn't notice ANY reduction in noise. What is DOES do is deflect the exhaust so that dust isn't stirred up by the exhaust before it's vacuumed. I was hoping for drastic reduction in the considerable noise level of the vacuum; I'll keep it due to the useful exhaust deflection.
I think this muffler qulets the noise down of my 4 gallon Ridgid only slightly. It's biggest benefit is to difuse the exhaust to keep things from blowing all over the place when the vacuum is in use. Many other reviews have mentioned this fact and it's true! In fact, when I bought this part today, another gentlemen was buying one, also, because of the same problem. Personally, I think Ridgid should include this part, or something similar, to help with the exhaust problem. If a person had a small length of PVC that would fit in the exhaust hole, it would be easy to cap it off, drill some holes, and you'd have something for free that would do the same job. So, think about picking one of these accessories up if you get a Ridgid vac (or other brand) if keeping flying dust and debris to a minimum is important to you.
Rigid calls this a noise muffler. But I don't know why. I can't tell any difference in noise volume, but I don't care because I bought it to diffuse the exhaust so that the exhaust doesn't blow saw dust or for that matter any kind of dust on the floor behind the vac all over the place and back up into the air making a continuous mess. This so called "noise" muffler does a terrific job of that. Just what I wanted it to do
Doesn't do a bad job of noise reduction, works well as a diffuser.

Review 17 for 2-1/2 in. Noise Reduction Muffler
Don't bother if you want to make things quieter

This actually made my vac LOUDER, replacing the low-pitched whooshing sound with a high-pitched hiss as the air hits the foam insert. This would function fine as an air diffuser however, if the exhaust blowing straight out is a problem.
