- This week at Project Build Stuff we are answering, what dust collector should you buy for your DIY shop. There are a tons of options when it comes to dust collection so we put a handful of contenders to a head to head shootout to see which is best. We tested for noise, suction, and performance on multiple tools with some very suprising results.
TOOLS

Oneida Dust Deputy: amzn.to/33fSskX
Shop-Vac: amzn.to/3ggkErH
Powermatic Dust Collector: amzn.to/30eGkPi

Reducing the 4in house down starves the dc of air. Shop vac is low volume high pressure while the dc is high volume low pressure so hooking up a dc to small ports isn't letting it get the air it needs.
Thanks! Super helpful…my shop vac just died and I think this is great info on the next steps. Awesome
Yea no. The Powermatic is made for larger port tools the others like the shopvac are best at smaller ports. Hook up the Powermatic to a 4 inch port on a tablesaw and it will out do the rest. everytime you go down in size on the hose connector you are restricting airflow on larger systems. Shopvac type systems are best for things that come with small ports hand tools, palm sanders etc. Dust collectors like the powermatic with high cfm ability are designed and made for large port tools tablesaw, jointer, planer etc. Not a good comparison.
This is really a wise consumer comment explanation. thank you
I am surprised by your CFM numbers. First off, nearly all manufactures report "free fan" CFM numbers in their specs which are over estimates. Free fan means no hoses or filters. So that fact that you were getting higher CFM measurements than claimed, with hoses and filters installed, could indicate a problem with the measurement technique. For example, your Shop Vac specs claim 140 CFM. Add the filter and a length of hose and that should drop dramatically. In my experience to around 80-90 CFM. If the filter has any dust in it at all that number will drop further. These principles apply across the board for all your systems.
I can't read the mode settings on the screen of your Anemometer. But on the 2.25 inch port test for the Shop Vac, the numbers show about 2700, which you label "270 CFM." I suspect you were possibly measuring linear feet per minute, so 2700 FPM. To convert that to volume, or cubic feet per minute you need to divide by the cross sectional area of your inlet. A 2.25 inch port open has a 0.028 square foot cross section. So, if I am right, and I may not be, 2700 fpm / 0.028 sqft = 75 CFM. That is a much more realistic number for a Shop Vac with a partially dirty filter and a hose installed. In order for an anemometer to report CFM you have to enter the cross section in square feet. So another possibility maybe that was not entered correctly. I don't really know just guessing.
For the planer test, there is no way to ensure that each pass through the planer produced the same number of chips and that those chips weighed the same. So there is some uncertainty in the results. Also for the Buck Tools and PowerMatic units, you added unnecessary air friction by adding the extra 4 inch to 2.25 inch coupler. Your planer's out put already supports direct connection of a 4 inch hose. Typically, adding couplers and fittings robs you of CFM, so those machines would perform better directly connected. Also, it is clear in the video that the 4 inch to 2.25 inch reducer does not fit tightly in your planer's output fitting, it's loose. Air leaks will also rob your system of CFM, so again those units would perform better with tight connections.
For the sanding test, there is also a lot a variability in your method. There is no way to ensure that the same amount of dust was created in each 30 second session. Also, a good portion of the fine dust produced by sanding will be imbedded in the unit's filter, or if the unit has low efficiency filter will let the dust pass right through back into the air. So weighing the dust from the bag or cyclone bucket does not really tell us anything. Also, as other's have mentioned, the high volume low pressure dust collectors are not well suited for small tools like sanders. You can use them, and they do collection dust, but will never be as good on small tools as a high pressure low volume dust extractor or shop vac.
If it were me, and I could have only one, I would pick the PowerMatic 073 by a wide wide margin. It is the best quality and most powerful. I would toss the old woven filter bag and put a 1 micron shaker felt bag on it. Should be able to get a 42 inch bag for $40 - $50 or so.
Agree with the comments below. 1. thanks for testing the different options with relevant, objectively-measured criteria. The summary tables were nice. 2. the high flow/ low pressure machines perform best with large diameter (4") tubes/ tools like your table saw. 3. the HPLV shop vac based solutions work best when hooked up to tools through skinny diameter (2") tubes.
Unlike others here I think you did a great job doing what set out to do. Determine what is best for a small shop. Yes large dust collectors don't work well when connected to small ports, so if you have a small shop with small port tools don't buy one. I don't really get what the other commenters here were expecting. Were you suppose to buy a second planer with a larger collection port and use that on the powermatic and bucktools?
What I found incredibly interesting is that the entry level dust collector actually kept up with the shop vacs on the smaller port tools. I had thought I needed a dust collector for my table saw/planer AND a shop vac/dust deputy for router/sander but it appears the entry level dust collector could fill both roles quite well. So long as you're not doing a lot of your own milling.
Holy wow your commitment to detail here is impressive! Great video - love the info. I recently upgraded my rolling shop-vac to the Central Machinery (Harbor Freight) dust collection system. It seemed like a good bang-for-buck and your tests make it sound like the upgrade will be worth it 🤙🏻
Excellent review with real evidence. Actually showing the results with weights, dB etc. really steals the show compared to descriptive videos of mere perception. Thanks for sharing.
Thanks for sharing your results from your quite thorough testing. Yes, we know that putting a smaller intake on a dust collector starves it of air but your test showed that the higher powered Powermatic suffered much more than the bucktool which I found surprising. Great info!
Thanks for posting this! I was looking for a detailed comparison between a diy system like yours and the same Bucktool model and this was very insightful!
Happy I could help
Great video! I was wondering if hose length was considered when testing or if that has any impact at all?? I really liked how you tested the DBs inside the garage, inside the home, and outside the garage! All very important when working from a garage shop!
Please can you tell me what type and model of filter is for cement or concrete dust. when doing a polish. thanks
For the sanding test, shouldn't you be using a new/unfinished piece of wood for each one? For data driven results, each test should be as perfectly equal as possible. I have to assume that the rough wood in the first test simply produced more dust than the last test, regardless of the collection system.
AND a new sanding disk.
The powermatic picked up the least… but it also had the least shoot out of it when planing…. Seems like it wasn’t cutting as deep as the others
Good videos! Keep them coming
I appreciate it!
Thank you so much for introducing me to Buck Tools. That unit matches the dust right I've been eyeing but didn't want to drop $800 dollars on
When I came to check out your father's Grizzly saw and you mentioned you make CZcams vids, I didn't think I would come to find your channel so quick! Haha. Great content man, good luck with your channel!
In the cfm test you need to calculate area of the hose opening/size and insert it to the cfm meter. Shop Vac and DIY had way too high numbers. Also dust collectors should never be connected to smaller than 4" hose.
Good videos! Keep them coming.... I Subscribed!
I appreciate it!! 👊🏻
The cyclone cart isn't accounting for anything in the shop vac or on the filter
Great video, next time you do the sound test, don’t play music over the audio for the machine’s decibel reading.
I think the big difference on the dust collection was due to the machines having a different CFM depending on the size of hose that's connected to it as per your CFM test
Great vid man! I attached a muffler to my shop vac. Barely helped. Plywood is a great fix!
In your last two test, amount of chips and dust collected. Your planer passes should have made the same amount of chips/dust per tool test. Same with the sanding test. If one or two machines excelled with what was collected. For the other machines test'. Where did the chips/dust that wasn't collected go?
Not a bad Christmas present after all.
Love it!
I enjoyed your video and I found it helpful, however one thing occurred to me. You made no mention of the condition of the filters, and this can completely change the performance of a Shop-Vac or dust collector.
Were these all used with new, clean filters? If not, your results are inconclusive, and the DIY unit with the cyclone would have a distinct advantage.
Great question, while the filters were not brand new all Machines and filters were throughly cleaned before hand to give them the best chance for success.
Great video. However so many factors missed. Connecting to the planer with the same size port just makes no sense.
Also sanding your not factoring in that dust gets into the filter bag etc more so then a shopvac with no filter etc. So many missed things needed to factor into these measurements. Restricted airflow and all.
The powermatic is a chip collector and not a dust collector. Other then that nice video.
You choked the p m with that little fitting
If you're looking to spend $200 (+tax), then go with the Harbor Freight. Nothing will beat it at that price.
Also like others mentioned, don't bother testing chip collection when you're reducing the hose size. CFM is dependent on the size of the hose, length of hose, and other factors. This guy doesn't seem to know why he's testing. The big hoses (4") are designed for large cabinet saws, large planers, and large jointers. Those large equipment come with standard 4" dust ports (or larger) and have a minimum requirement of 350+ CFM. I tried collecting dust on those w/ a shop vac and got about 25-50% of the dust it generated.
4 inch hose with downsize adaptors. thats the worst thing you can do, kills all suction to a normal shop vac at best as you show. Guess we could call it what not to do on a real dust collection system.
