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
The muffler barely makes a difference in the noise level. I purchased it thinking that it might add another layer of filtering out the particles expelled in the exhaust of the vacuum but that was not the case. In fairness, the product was not designed for that and I knew that going in but decided to try it anyways. Bottom line, if you are looking to reduce the noise level on your vacuum, this will not help much.
Pros: Easy to Use, Easy to Install
Cons: not useful, makes no difference in noise level
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 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 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 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.
Most of the noise made by Rigid Vaccums I've used is from the motor and not by the blowing air out the back. The title/discription of the product is thus misleading. If you read the box, it says it's an air difuser which is much more accurate.
My suggested uses: I actually bought this not for it's noise reduction capabilities but for two other purposes which it serves quite well! 1. Difuse the air blowing out the back, working in a dusty environment the outlet often blows the dust around making it harder to clean, this difuses the air so it's not blowing so hard in any one direction. (This also prevents water from blowing out the back when sucking up water.) 2. When sucking up dirty water (like when my sewage backed up in to my basement) the vaccum will suck up all the floaties which easily clog the pump attachment... Using the difuser at the end of the vaccum to suck up dirty water acted as a filter that helped keep the pump clear of debris.
Conclusion: If you're looking to prevent dust from blowing behind the vac or using it as a filter for wet debris while using the pump I'd recommend it. If you want it to reduce noise, it ain't happening with this device.
