Works great for the wind, not sure about sound
I mean, maybe it’s a little quieter? But the main thing is that the wind doesn’t blow 100 mph out the back anymore. Just on a standard Ridgid HD shop vac, works great.

effectively muffles sound
This part helps to effectively muffle sound while not impacting suction performance.

Mostly worthwhile, still noisy
I bought this for a small Shop Vac which has 2.25″ / 58mm diameter intake & exhaust ports. With a 2.25″ diameter vac you will not need the red tabbed 2.25″ to 2.5″ adapter to connect the diffuser. Models like the Rigid will need to use the adapter with the diffuser, and it will stick out further from the base. My model doesn’t have a lip for the tab on the top of the diffuser to fit into, but the fit was snug and the tab didn’t interfere with the connection. I’ll probably make an indent for the tab using a multi-tool later if needed.I couldn’t tell any difference in noise with or without the diffuser installed. I think that’s why it’s called a diffuser and not a muffler. I bought this to reduce exhausting dust back into the environment while vacuuming. I think it only does an OK job, but it’s better than nothing and I don’t regret the purchase.

Works as advertised.
I bought this product for my new DeWALT 12 gallon Poly Wet/Dry Vac.Pros;Follow the enclosed directions and youâll find that you can remove the adapter and it will fit fine in a 2â exhaust opening.Easy to take apart and clean.Helps keep the dust from blowing out of the exhaust.I would say my uncalibrated DB meter on my iPhone showed about a 5 dB difference in noise with and without the diffuser measure at 10 feet.Due to my hearing aids, I have to wear the ear muff type of hearing protection so I actually hear very little sound. When using ear plug type of hearing protection I hear a lot more noise.Cons;On my vac this sits above the tool bag which causes a little obstruction to get to the tools. In my case, I was removing the tool caddie as I was sucking up old bark and dirt so I didnât want to get inside of it.

Works well
I bought this for my Rigid (Home Depot) vacuum cleaner, and I suspect it’s made by the same company that actually made the vacuum. Connects perfectly, and does cut down on the noise.

Practically useless – will return
I searched for “shop vac muffler” in Amazon. The search results included only items of this type, which are diffusers with a relatively open pore foam filter on it. I mistakenly thought this would reduce some of the vacuum noise but I should have read the description more carefully. This is just a diffuser and exhaust filter. It does nothing for noise. In the end it’s another piece of vacuum accessory that will get clogged up and will require cleaning, especially if you’re using your shop vac frequently and for wood working for instance. I use a cyclone dust collector with my shop vac so I don’t have an ‘debris’ shooting out of my vacuums exhaust port. What I really needed was a muffler and this isn’t it. Will be returning it promptly.

WORKSHOP Wet/Dry Vacs Vacuum Diffuser WS25025A 2-1/2-Inch Diffuser
Works perfectly on my Ridgid vacuum. This is essentially the same thing as the Ridgid branded one. I say “essentially” because it might be slightly different, but I haven’t bothrered to check the “real” one that I have to be sure. If they are any different, it would need a direct comparison. It might be the same thing exactly as the Ridgid branded diffuser.This isn’t a knockoff, it’s just a sub brand from Ridgid, and that’s why you can use Workshop attachments on your Ridgid vacuum, assuming you order the correct attachment port size for your vacuum.

Very handful tool
This item keeps the dust inside the vaccineSuper cool
Really helps with exhaust, it diffuses successfully preventing dust being blown all over. It makes a slight difference in noise, but only from the exhaust. This device cannot and is not designed to make the vacuum quieter because most of the noise comes from the motor. It does quiet the exhaust by decreasing it.

Did not find much difference in the noise. A bit effective in managing when vacuuming very dusty places.

Encajo bien y redujo un poco el ruido

Esse é similar do original da Ridgid, mas gostei, é difÃcil achar esse produto no Brasil, impede a massa de ar de sair, o que é bom, mas não reduz tanto o ruÃdo assim, encaixou na saÃda sem o adaptador.
