WORKSHOP Wet/Dry Vacs 2.5" Muffler/Diffuser

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.

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.

I bought this based on a review I read that it might quiet down my shop vac, and also filter a little more dust. The filtration is about as expected, not as much noise muffling as I was hoping for.

I bought this product for my new DeWALT 12 gallon Poly Wet/Dry Vac.Pros;Follow the enclosed directions and you’ll find that you can remove the adapter and it will fit fine in a 2” 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 didn’t want to get inside of it.

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

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.

Just buy it lol

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.
