To clarify we are NOT a testing lab but we feel we do a good job at what we do. Sounds like someone is looking for some air-time and exposure for your vac. Thanks for commenting — next time be transparent that you work for a manufacturer. Good catch, Rob. I could never support a company with these kind of unethical deceptive practices. But now.. The point is that obviously a Hepa filter would further restrict air flow giving the some brands a unfair advantage.
I would be curious how much the Hepa filter affects performance. The milwaukee can be run with its hepa filter removed because of their multi filter system.
This would allow testing with the same unit to discover how much performace is lost. In each test case, we used the filters from the manufacturers that the manufacturers promoted as meeting the silica standards. These units, like Bosch, it meant that the paper filters that ship with the units need to be replaced with their Bosch HEPA filters before the dust collector and filter can meet the spec in combination.
In another special case, Festool, their unit has been EPA certified and rated for lead paint removal work for well over a decade. TBB based our overall performance measurements on Airwatts. We chose Airwatts because it is a result of both suction and airflow. On the static suction side, the maximum inches of water column are reached when no air is going through the unit so filters have absolutely no bearing on that particular test.
On the airflow side, all of the units had the manufacturers HEPA or equivalent filters, tested clean, and installed along with clean fleece bags. Our air flow tests were less about the filters because of the fleece bags keeping them clean than if we had run the tests and allowed the dirt to get entrapped into the HEPA filters. To summarize, TBB remains very comfortable with our approach producing a consistent and level set of results.
Hey been watching your videos here In Australia for a while you guys do a great job. I just wanted to ask your opinion as I just ordered the Milwaukee extractor featured in this video. I wanted to know if you guys think it would work well with my Festool track saw, sander and other wood working tools also?
Many thanks Jimmy. They do such a great job especially with masonry applications. The Dustcontrol DCC Eco is my choice for this, compact size, 32 pounds empty, can handle months of steady work before a filter change is needed. The Metabo one is actually made in Germany by Starmix they did manufacture for other brands like Makita, Fein, Hilti as well in the past.
Thanks for these tests! I will only use a fleece bag and hepa filter, but I see I have a choice between manual and auto filter cleaning. Will a cyclone I already have one paired with a manual filter cleaner work as well as a machine with an auto filter cleaner? The prices are in the same ball park. Any thoughts will be appreciated. Auto is my preference as it provides the Oneida Cyclone Dust Collector Jacket most optimum performance keeping that filter as clean as possible.
Were these done with auto clean on? The tests were done with the autoclean turned on. Obviously, the older the filter the performance will drop off…but autoclean features have drastically improved that performance for longer periods. Thanks for the great review. What about air quality of the exhausted air? How fine are the particles being blown back into the room? To me this is the most important metric. A couple of comments. First, a good start to evaluation of a complex product.
Airflow — air watts are calculated a given flow point. The water column measure is the suction head at zero flow one condition.
The CFM measure is a quasi-open flow condition 2 with nearly zero suction pressure and maximum flow. Both would have almost zero air watts. This will give you a mid-range operation point more indicative of real operation with a partially blocked filter and load from tool pressure drops.
With a static pitot tube probe in the tube connected to a manometer, then a comparison could be made just on the relative pressure readings which will show a combined flow and pressure value higher being better. If you want efficiency, a measure of the input electrical power could be used in conjunction with the airflow.
Sound — the measure has some merit but has some issues that could be cleaned up in future work. First, the phone mic has limited ability to capture all sound. They are designed to filter out extraneous noise while transmitting speech. Purchase an inexpensive audio mic for sound analysis so that all frequencies are properly captured. Second, consider moving the mic to about a meter away from the source for better representative values.
Also, measure sound in several places around the product. Both positional changes may show that directionality may be a factor in the evaluation. Finally, how are you controlling background noise so that they are not intruding on any given test point? Unfortunately I have to agree that this comparison is merely a good start that raises as many questions as it answers. Dusts collection from hand-held power tools is every bit as important as it is from the stationary tools, but actual data is severely lacking by comparison.
As noted, the data from this review provides the CFM at effectively no static pressure and static pressure at zero CFM end points, but almost no data about the vacuum curve in between. Completely made up example to be clear, just attempting to illustrate the issue.
Ideal test would adopt methodology as Fan Guy suggests, but with data points for multiple orifice diameters in order to chart the relationship between CFM and static pressure across the potential operating range. I find many shop vacs noisy enough that I wear hearing protection when using them. Those who are concerned about noise should consider the length of the hose supplied with a vac, or shop for a Cyclone Dust Extraction Zhihu long hose they can connect.
Farther from the vac will be less noisy. I agree with Fan Guy about testing with a smaller diameter length of pipe at the end of the hose. Again the length and diameter of the hose are relevant, a longer, smaller diameter hose will be likely to reduce flow, but is Cyclone Dust Extraction Examples easier to work with. Initially I was puzzled by how much your side-by-side results contrasted with to side-by side comparisons of the manufacturers specs from their websites.
The manual specs yielded side-by-side comparisons that were more in line with your results. I was also puzzled by the erratic falloff in cfm once the bags were dirty. The vacs all seem to have about the same wattage blower. Perhaps the difference is explained by the surface area of the filters and the size of the bags.
Dust extractors extract dust… or do they??? Earlier, William Anderson asked about air quality. You answer was that you cannot test everything but I would think this is a fundamental question begged by a dust extractor.
This is a major issue of health and safety. Does it extract dust? Everything else is honestly only interesting. High mechanical performance numbers are useless if the unit is not properly filtering out the most dangerous particles, which are the ones we cannot see.
It would not be an easy test but no more difficult than the other tests you set up. And far more important. I applaud your effort, but I honestly think you missed a core test which is of great interest to our lungs. No offense, but Consumer Reports would have likely done this.
We interview product managers and engineers from the tool manufacturers. We ask them their thoughts on our testing approach, and try to get their consensus on our approach. But, we can test the performance to suck up materials one of the primary functions of these tools , and compare them to each other. Yes dust is critical, but the performance to get the job done is as well. The gents at TBB did a great job of doing a relative comparison of several popular units.
They developed a test protocol, explained their procedure, conducted the evaluation and from what it appears they presented the results transparently. Yes there was some subjectivity on what and how to test — but that is true of almost any type of testing. Bagging on them about not developing the actual fan performance curves or comparing this and that are being overly critical. I commend them for being a better job than most reviews that you see on the Internet.
Or better yet, go out and conduct your own testing and absorb your costs and time and post your results of particulate effectiveness or comparative fan Cyclone Dust Extraction 700 performance curve and wire to air efficiencies. Agreed that would be a cherry on top. Jon — Thank you! We put a ton of time into doing these, no one pays us to do the tests.
Sure we get traffic and that helps build our brand, but we purposely make everything transparent so guys can make their own final judgement. Filters are important but they are not what was evaluated. Great Comparison. However, not all the extractors came with a.
So the test is not really comparing apples to apples per say? This will throw off all the test. Great test guys, really appreciate the info and hard work. Would be great to see a common Ridgid or similar vac in the comparison to have a benchmark. Hi, I was wondering if you considered looking at Dustless Technologies? Would really appreciate hearing your views on Dustless Technologies. There is a company in Burnaby, BC, Canada that has been selling and renting dust extraction systems for the concrete finishing industry for over 30 years.
Once the Corona virus shut-down ends here I will take my flow measuring system to their shop and get some readings on new and used Dustless vacs for you. I have recently purchased the Makita VC and have several Festool tools.
I have had difficulty finding a hose adapter. Are there any that you guys would recommend? Just wanted to say thanks for the effort and hours that you did for this review, very informative. Great job. My work has the hilti you tested and is, as you concluded, a superior product. I was thinking of buying the Fein turbo II for home.
Again its for home use. Carpentry, drywaal, small shop and consruction projects. Henry — Good morning. Honestly, for home use, even inexpensive vacs from Craftsman or Ridgid will do the trick.
The big difference on the higher price ones is trying to meet OSHA dust regulations and having vacs that can keep up with heavy commercial use. But only 2 vac has options install on the top boxes with tools,its Festool and Bosch.
This is huge benefits. I personally using Bosch for years and like. Only power cord should be little longer. We have not reviewed the smaller ones.
Yes, pricing changes all the time, we put the data up so everyone can make their own evaluation, and likely look at pricing when they make the final decision on what to buy. To fit it to common woodworking tools like Makita, DeWalt, Festool, etc. Hilti charges a lot of money for each of these things.
Rethinking things as someone that primarily deals with woodworking tools and already owns a mixed set of tools DeWalt portable table saw and compound miter saw, Festool track saw, various hand tools , it would make sense to factor some of these things into a decision rather than just testing suction capabilities on a few different types of materials from the main hose attachment.
Hi guys, great article … but out of date now as many of these models are no longer for sale. Any chance of a retest with latest models? Also, would need to ensure all models are compared within the same filtration class ie.
Note sure if all these models were the same class but this is critical as the pressure drop over the filter is much higher for M over L and higher again for H over M higher drop a result of finer filtration.
After reading your review, leaning towards the Makita! However, as flow rate and static pressure still seem to lag the Makita from their published data and the latest Makita also has auto filter cleaning and flow rate alarms etc. So I was looking at buying the Makita tool you listed but seems like it has been discontinued… It has been replaced with a new model VCL. Any chance that you run your tests with this model and update your results?
I looked in Amazon and the new model does not have great reviews for what its worth , so I am curious how much alike is with the older model. Daniel — Not likely to happen anytime soon. These tests are a TON of work, and we have a long list of other tools to do Head-to-Head comparisons on. The new one is certainly a solid unit. This vacuum was featured in our previous Dust Extractor HeadHead comparison and will be the subject of a stand-alone review soon.

Dust Extractor Lineup The eight dust extractors used in this Head-to-Head evaluation are listed below. Suction Water Column Test — This provides a relative measure of the motors suction power. We also tested suction with a meter to compare the results to the water column test. Airwatts — Calculated standard measurement used in the vacuum industry. Best indicator of the overall relative power and efficiency of the units because it takes into consideration both the water column and the CFM factors.
Noise — Decibel measurements including the average and maximum value under high load. Cost — Current costs available online. Ergonomics and Features — We ranked each vacuum in categories including: Canister handles, wheels, locking caster feature, accessory attachment, hose attachment to vac, ease of controls, auto-clean switch, power broker switch, maneuverability, hose storage, cord storage, cord length, hose features, ease of filter change, mess changing filters without fleece bag, compactness, and weight.
Dust Extractors — Testing Measurements One of the key reasons to develop a Head-to-Head test of dust extractors is to objectively measure the relative differences in performance.
Suction Measurements Water Column Jig To measure static power suction we used both an industrial gauge that registered up to inches of water column, and a water column test. Dust Collector Noise Measurements For each dust collector we also measured the noise in decibels. For the clean condition the top three included: Hilti For the baseline clean dust extractors the top three included: Hilti Airwatts — Results Below are the results of the airwatt calculations.
Noise Results Below are the results from our decibel measurements. As you can see below the top three quietest were: Makita Dust Extractor Costs Cost is always a factor in determining what tool to buy. The average score across each category was used to rank the dust extractors with the top three being: Fein with an average score of 1. Third Place — Festool In third place was the Festool Related Posts No related posts.

However, it seems clear that he still believes additional precautions are still needed, particularly since the effectiveness of the dust extraction varies according to the type and make of tool and of course, working with hand tools generates dust anyway. To make things worse, air born dust can explode when mixed with the right quantity of air.
Who knew woodworking could be so dangerous? Talking of exploding particles, one theory about the Great Fire of London that started in Pudding Lane on September 2nd is that it was caused by the ignition of air-born flour dust in a bakery. Contemporary accounts had it that a very small number of people died in the fire — the official figures only record 6 deaths — but it is likely, given the speed the fire took hold, that there were hundreds of others deaths that went unrecorded.
To be fair to bakers the members of the Worshipful Company of Bakers did eventually apologise to the Lord Mayor of London about the whole thing. Still, better late than never, I suppose!
