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.
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
NOT a muffler. Even on the packaging it's labelled as an air diffuser.

No, I do not recommend this product.
I purchased this just to diffuse the output air so as to not blow dust and dirt around so much as I'm vacuuming. I knew it didn't function as a muffler as other reviewers mentioned when I purchased it; even on the plastic packaging for the part it was listed as an air diffuser, not a muffler. So, the fact that it didnt quiet down the vac didnt factor into the star rating I gave my review.
However, this part causes too much backpressure due to the restrictiveness of the sponge in the "diffuser". You can easily feel the difference in suction with your hand. As a result it considerably decreases the effectiveness of your brand new Ridgid shop vac. I will definitely be returning this and rigging up my own for $2 that doesnt restrict air flow, doesnt obstruct the use of the tool caddy (on the 14gal model) and diffuses the air stream. Save your money...
This 2-1/2 in. Noise Reduction Muffler works GREAT! Would highly recommend this muffler for the noise reduction of your shop vac. I couldn't believe how my shop vac sounded no louder then my house vacuum by using this muffler. I am very happy with this purchase.
Pros: Durable, Sturdy, Easy to Install, Good Size & Weight
I bought this because it was recommended for the vacuum I bought, though I had to take off the adapter piece in order to make it fit. Honestly, it does not reduce the noise. BUT! if you are vacuuming up finer particles like hair and dust and are worried about things getting blown out the exhaust port, this is a great little filter to reduce that. I gave an Average rating because while it is a useful item, it does not serve the purpose it was intended for, also, I don't think it's worth what I paid. My husband probably could've rigged something up out of a fish filter sponge for less than $5.
I purchased this item for use with the 4 gallon Ridgid wet/dry vac WD4070. With a powerful 5 H.P. motor comes a loud exhaust. So just like a hot rod with open headers, put a muffler on it so your not giving everyone a headache. I work in a lot of occupied finished homes for customers of high standards and to make my best attempts at keeping the customer happy, the noise reduction makes a big difference! The other great benefit of this item is that it diverts and reduces the speed of the exhaust from blowing straight out and stirring up more dust on the jobsite. It is light, compact, breaks down and is able to be cleaned easily.
Pros: Easy to Clean, Easy to Use, Easy to Install, Good Size & Weight, Nice Design
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 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.
Bought this from reading other reviews about disspersing the exhaust air. And it does a good job doing that. Now the vac does not blow the blinds in our kitchen and dirt all over before you can clean it up. As far as the sounds goes it's a shop vac still gonna be kinda loud. But works very well for what i wanted it to do!
My wife would complain when I used my shop vac to clean the house floors. She said the exhaust port would blow dirt and hair( from our 2 large dogs)all over the house. I purchased Noise Muffler to help disperse the air flow out of the vacuum and It works great! It also does quite the vacuum a good rate. My kids thought something was wrong with it because it wasn't as loud and obnoxious as usual.
This product arrived fast and well package. It description was clearly defined and fit the machine perfectly. The online ordering process was quick and simple. Thank you Home Depot for a great job. Steve
