The more loaded a filter is, the better if filters. The tradeoff is the lack of airflow that comes with it being loaded. The particulate that is caught acts as additional filter material, and so long as you can maintain airflow, it should filter more effectively than if it was brand new. You can think of a metal grate with 1" holes and dumping gravel over it. The larger rocks will create smaller gaps that will sometimes catch rocks below the 1" hole size. With filtration you are dealing with viscosity, static bonding, and a few other things as well but it works as a basic metaphor.

Yep. That is my suspicion. Got a new filter to test against.

I work in the field as a finish carpenter most of the time, and I personally enjoy the feeling of pulling up to a clients jobsite breaking out my Festool setup and seeing the look of confidence and excitement in their eyes. Furthermore, the clean-up process of owning Festool is beyond worth it. I can cut a 20' stick of material, get it on the wall, and have my setup broke down in 10 minutes...enough said. BTW I'm 53 yrs old and work alone.

I am an install manager for a cabinet dealer, we hire subcontractors for cabinet installs and one of the first things that will catch my attention is the tools people are using, if you roll up with a few crappy ryobi tools and harbor freight levels in the back of a pickup truck (this has happened ....) I am not going to feel very confident that you will be paying any real attention to detail or that you actually know what you are doing, a good craftsman will buy good tools and they do it for a reason, they are more accurate , the cost of them should not be too much of a problem if you make a living doing that kind of work.

[@AsTheWheelsTurn]

they may not know what the brand is but the look of it shows that a person is organized and has invested in their tools. trust me I manage cabinet installs for a large cabinet dealer and the guys we have that are set up with festool or Milwaukee where everything is very organized and matching without a doubt breed much more confidence with clients. and from my perspective it is an indicator that that person is actually paying attention to detail and dedicated to their craft because they invested money in it, it also lets you know they MAKE money ....compared to some cowboy hack that rolls up with some busted up tools and leaves a huge mess behind .@@Ekrindul

[@chrisoconnell8432]

The results you got in your test make perfect sense. In a lab setting where you could completely isolate the air coming out of the filter, you'd see much lower 0.3 micro scores from the HEPA filters. But in a garage setting the sensor is picking up all the air in the garage, not just the air coming from the shop vac. I bet you could place the sensor anywhere in the room and you'd get similar results. One thing you missed in your test was a control where you cut/sand some wood without any shop vac running and see how sensor results compare. It'd also be beneficial the test with the sensor as close to your face as possible. It really doesn't matter if the air coming out of the shop vac is cleaner, it matters if the air going into your lungs is cleaner.

[@wittworks]

Great thoughts.

[@geraldaugustus739]

That would be a fair point, except across tests each vacuum was still showing relative consistency. If you test 3 vacuums 3 times and your results have a consistent relationship that suggests even if the room is having an impact (which it certainly is) there is still a correlation showing.

[@sanderd17]

@@geraldaugustus739 There's definitely a correlation on dust particle output. But the question is how important it is when compared to other parameters (like suction). Are you better off with a vac that has great filtering, but with a lower suction (so more can escape at the tool), or are you better when a vac that has great suction but little filtering? It may depend a lot on the placement of your vacuum too. You're usually pretty close to the tool, but the vacuum can be further away, quite often with the exhaust turned away from you.

[@ipick4fun27]

I always have this thought. Run a long hose and have the show vac on the outside of the workshop/garage or a separate compartment that dumps the air to outside.

[@devgru1079]

Well who the hell cares what the isolated air results are, the air I'm breathing is obviously the open garage air

[@MagicianOfOz]

One very likely reason the old shopvac had a lower output of very small particles is that the filter is clogged, which actually increases it's ability to filter things out, but at the cost of air throughput (and thus worse suction). If you want to further test that you could simply repeat the test for yourself with the festool turned down to the lowest speed, and compare it to itself on highest speed.

[@alphaforce6998]

But if it has enough suction to keep up with the waste from the tools, then it's still a better value even with lower suction...as it's not releasing a higher amount of fine particles than the more expensive options.

[@Auto209]

@@alphaforce6998but what about the fine particles near the tool where the person is breathing? The scan is getting live data at one point. We’d need to have probably 2 at least to see the full scope of the air quality with these filters/vacs

wouldn't a better test be to put his airflow meter on the exhaust? that would show if the old vacuum is outputting the same amount of air as the new Festool or the new vacuum?

[@Brandon-rc9vp]

Good video, one note - the anti-static hose isn't about shocks, it is about dust not sticking electrostatically to the hose. Lots of static electricity is generated when moving air over an insulator, good industrial antistatic dust collection systems have conductive piping that is grounded through a 6-8 MOhm resistance to allow the static to dissapate.

[@jeffmastin]

If I am using a plastic hose, can I use a section of metal hose with the ground attached?

[@mjolnirswrath23]

Or just use a secondary hose and venturi manifold to mitigate static transference...

[@michaelrobinson9643]

Precipitation static (P-Static) is in the hose and the dust particles. Dissipating it if the hose is not conductive would be best done how? A metal section that's grounded partway in the run or before the cyclone? Static in the cyclone can be effective too as a means of reducing dust velocity. I wonder where that leaves the options for a tool -> cyclone -> vac setup with soft hosing?

[@cjsawinski]

@@jeffmastinyou can use some scrap wire on the hose, just ground it somehow… problem solved with scrap

Well it's that but also any static spark can ignite dust particles and make your workshop explode... So... it's a LITTLE about the static sparking/shocks...

[@mehdimarashi1736]

Hey man, nice video! I noticed something you didn't discuss, and that's that 50% more air velocity you got from the festool. If the air hoses have the same inside diameter, 50% more velocity means 50% more cfm. 50% more cfm means 50% more of the HEPA-filtered clean air you need to breath safely. Imagine your workshop with 8000 cubic feet of air inside of it. You measured the air quality near the exhaust of the vacuum, which is arguably the cleanest air you have in the whole workshop. The festool sucks 50% more of the dusty air near your tools, and that's important, too. So, you have a solid advantage for the extra money you paid. Don't feel you wasted money and gained nothing except a logo and a smaller more convenient system. The air you gained might not be much cleaner, but you have 50% more of it.

Internal dia is not the only component. Resistance and turbulence will influence the outcome too?

[@mehdimarashi1736]

@@michaelrobinson9643 What I'm saying is that air discharge = "area section of the air jet" times "average air velocity". Resistance reduces the velocity. Turbulence changes the velocity distribution in the jet, but in the video he is measuring some sort of an average velocity and omits the distribution. My analysis is not perfect, but it shows the bigger picture correctly (at least as much as I understand what is going on). If we know the air velocity, inside diameter gives us air flow, and here we have a measure of velocity if not the velocity itself.

Congrats on another well presented and scripted video!. A sixth bonus feature of my CT Midi is that hose clogging and loss of suction can be quickly fixed by connecting the hose to the Midi air outlet port and blowing the offending crud back out of the other end of the hose. I made a 55 gallon food barrel into a potable cyclone chip collector using a Veritas cyclone lid. The Midi can then be used with 2.5 inch hose on my band saw and planer. Another reason your old vacuum can catch fine particles is that your filter is so caked with dust of all sizes that it catches the fine dust that it was not designed to catch.

[@wittworks]

Great tip! And I suspected the caked filter had something to do with it...

[@lomicwind]

@@wittworks my first idea too, you should test again with a cleaned filter to see if it performs the same in terms of airflow (I bet it will be better) and let more particles through too.

[@bed28391]

Great video, and very thorough! In order to eliminate some question, you could test the new rigid without HEPA filters, (with standard filters), and test the old rigid with new standard filters. Someone commented below that they weren't surprised because, "in a garage setting the sensor is picking up all the air in the garage, not just the air coming from the shop vac". That just further validates your test. What you care about IS the air "anywhere in your garage" and it will likely never be worse than where you checked. There could be some locations that are more closed in that do collect a little more, but in general, you covered the bases. The old rigid and the new rigid are perfectly safe for the average person. The only remaining question to me would be the accuracy of the measurement tool. You did some work to validate that and your results were consistent on multiple tests and so I think that answers the question. The tool could be off an order of magnitude but the result is still the same, the rigid setup works as well as the more expensive unit. I think you nailed it. I am just now setting up a workshop that I have wanted for decades and considering what type of dust collection would be appropriate. Thanks for the great work.

The dirty filter is a game changer. The larger holes have already been plugged and particles have to be pretty small to get through. Put a new filter in the old vacuum and your particulate rating will go up significantly. Drill a hole in your wall and put the vacuum outside. Take off the filter and let the vacuum blow. You will get more suction and your inside particles go down.

It’s not a judgement on whether the user is actually a “professional “. It’s how the tool performs in all ways, from little details to smart motors.

Think of it this way; the less throughput the less particles coming out. If you had no suction you would have ambient particle count. So a slow / clogged pump will have lower particles, therefore you need to divide the throughput by the particle count. Assuming the volume of the hoses are the same so that the meters/second velocity readings are comparable. Old = 5.8m/s with 5070 total particles = 874 ppms New = 10.9m/s with 6850 total particles = 628 ppms Festool = 10.5m/s with 5380 total particles. = 512 ppms So for every unit of air coming out of the Festool there are less particles in it. There's just a lot more units coming through therefore more total particles.

I just bought the cyclone separator at HD and it's freaking awesome. I was out vacuuming the driveway of leaves and dirt, not a drop inside my vac, everything in the bucket. And I made a cart for it with scraps I already had, removed the vac wheels which were kind of flimsy, put larger wheels which I already had, and the whole thing rolls around great.

I have a Festool C26 which has a bigger motor. The bag lasts forever and will pack like a brick. I primarily use it connected to my miter saw, sanders and track saw. It was a game changer when I first bought it over 10 years ago.... it allowed me to cut in houses. The Festool is a superior system and way cleaner and easier when changing bags. I also use an ambient air cleaner on my jobs and shop..... I can tell the difference in my lungs.

[@apriori8413]

Footprint, noise, Bluetooth, rating, looks and resell value plus the fact that with the cyclone upgrade you don't need to change the dustbag for months, the Festool setup is one of the best shop tools i ever bought. The bluetooth switch is my favourite thing about it. No regrets if you can afford it.

[@Pantology_Enthusiast]

I made a simple outside housing and run the vacuum outside and ran the hose up through the floor because the HEPA filter restricted airflow too much. Since the Vacuum vents outside I just use a standard bag and filter. I also use one of those Buckethead cyclones to reduce bag changes. I found that adding a foam seal to the Cyclone improves the suction loss issue (or vinyl electrical tape). Also, having the vacuum outside helps to not add heat and noise to my tiny workshop.

[@JamesSmullins]

Venting the exhaust air outside is key, I do the same except I run a hose from the shop vac to the outside. My shop is a 8x8x20 shipping container so removing any dust I can from blowing back into the air is critical. Due to space and meth and meth addicts I can't setup entirely outside so I have mine mounted up on the wall above my tools. The shop vac hose reaches everything since it's such a small space. Cleaning kind of sucks sometimes but it's not too bad specially since adding the cyclone. I fixed the static shock issue by simply wrapping a thin bare copper wire around the hose which is connected to metal wall of the shipping container giving me solid grounding for the entire air system.

[@ericrichter7933]

Loved the video. I do agree that clogged filters do change filtration levels. Probably contributes to the lower flow for the old vac as well. I have an old craftsman shop vac and ported the exhaust outside kinda like people do with their dust collectors. I don’t use any filter at all since the dirty air goes straight outside. I run my shop vac into a dustopper for separation. Then for mobility, I set up a boom arm to get my shop vac to easily reach anywhere in my small shop. You should check and see if the dustopper has a good seal and see if that affects the airflow drop off. I use some foam on the edge where it connects to the bucket and that seems to help maintain a seal.

[@wittworks]

Thank you

[@johnkim1043]

you are clear and honest. rare but admired!!

[@aaawman2280]

High sir, your friendly nieghbor hood automotive tech here, Ford dealer to be more precise. The reason the old worn out machine done better is more than likely because of the old clogged filter. Filter efficiency increases as it becomes dirty, the filter is most efficient at trapping particles right before it is completely blocked. This seems to be proven to be because the holes in the filter that naturally occur become glogged and blocked causing the filter to be more able to catch particles.

[@wittworks]

Thanks. That seems to be the consensus.

[@hanshoutkamp857]

I watched your clear and honest KZbin movie with great interest. Understand your problem related to particulate matter; the festool machine lets through just as much particulate matter as the cheaper machine. Maybe the following information can help you: In europe, festool carries 2 MIDI machine models; CTL & CTM The CTL model is intended for dust class L and the CTM for dust class M In Europe we don't know "hepta" designation maybe such a designation is also a heavily exaggerated sales argument, which in any case is confirmed by your measurements. Good luck with testing. greetings Hans

[@datcolsol]

My understanding is that the antistatic hose is not so much for preventing the user getting shocked. Rather, it is meant to prevent sparks occurring in a possibility dusty environment. With the idea ratio of fine dust particulars suspended in air (stoichiometer ratio), a small spark can trigger combustion. This is a huge concern in dusty industrial environments. I don't think this is a big problem in most wood shops but antistatic hoses are safer and can be used anywhere

[@mattschreiber4251]

Kind of true,but not really. Understanding the danger of sparks certainty effects how you work. Good news is that in almost any small shop, sparks are not an issue. 4” and under DC hoses/piping are not big enough to allow a spark ignited explosion. So your shop vac is certainly safe regardless of the hose.

[@dankelly2147]

A long-time woodworker - at age 77 I’ve been woodworking over fifty years. I have been using Festool dust extraction for about ten years. With COPD I can sand and cut and not exacerbate my lung condition. I also run two ceiling dust filtration system. We’re it not for Festool in particular, I’d no longer be able to sand and finish wood. Perhaps if I’d have had their dust extraction system as a young man I would not suffer with the impact of COPD that I do now. When I started working with wood there was no awareness of the impact of sawdust on one’s lungs. What are your lungs worth? They’re taken for granted until you lose lung function. Take my word for it: life is a lot harder at 50% lung function.

[@mmgross144]

Actually the fuller the vacuum filter becomes the finer the particles it removes. The suction decreases but the filtration increases. I have used a 15 year old Rigid shop vac with a Dust Deputy with it for many years with few complaints but I sold Festool systems while working at Woodcraft. It’s a matter of budget and personal preferences.

[@cavalli821]

Hi. This is great to know. I need to sand a few kitchen cabinet shelves in kitchen space and wondering if the Ridgid shopvac with HEPA filter & bag connected to the sander would do a good job with dust collection. Thought about purchasing the Festool but multiple opinions. I also shop at Woodcraft in my area. What are your thoughts about dust indoors with the Ridgid shopvac with HEPA filter & bag hooked up to the sander VS. sander connected to Festool extractor? Thanks a ton if you happen to see this...

A sander is really what these are designed for. Sander create finer dust than saws. Testing with sander dust might give you better results because you will be generating smaller dust. If all the test dust is the size of golf balls than an old window screen will test well. Otherwise thanks for putting in the work and giving us something to reference.

[@jacknbg6819]

I also bought a CTL Midi 4 weeks ago to vacuum both my apartment and machines (mainly wood dust) when I work on the balcony. This also eliminates the need for a regular vacuum cleaner (which I needed anyway). The little one has a small corner at the bottom of the pantry behind the door and is super handy. I regretted nothing - at most me not to have bought earlier. The remote control will also be added by Christmas at the latest.

[@MarcosElMalo2]

Working on your balcony might be the biggest help because of the ventilation it provides. The biggest issue is that these tiny dust particles remain suspended in the air in an enclosed shop. The more ventilation, the less of a problem it is. I think my shop is pretty well ventilated (it’s drafty as hell and on a windy day there’s actually a slight breeze). But I also have a large rooftop patio where I could be working. I think I’m going to put a bench up there for working on good weather days. (I like to go up there when I’m manually sanding to enjoy the sun, anyway.) I would keep my tools and work stored in my shop when I wasn’t working up there.

[@krisin1834]

Great video. Another data point would be to quantify how much dust is collected in the first place (not easy). Lower cfms would likely result in more dust overall, but depending on the setup (e.g. cyclonic vs filter) higher throughput could also mean more dust suspension.

[@allenhess6583]

Thank You for your consideration in making this video. Very nicely researched, narrated, explained. I trust your measurements, most of us are hobbyist in nature and don’t spend 40 hours a week in the workshop so it’s not perfect but it’s good enough. Greetings from Maine

[@wittworks]

Thank you Allen!

[@MarcosElMalo2]

Keep in mind that his test is for his machines in his work environment. YMMV with your air filtration system. Still, anecdotal evidence is still evidence (it’s just less statistically significant). The thing with the expensive Festool is that I think it’s high probability that 1) Festool did extensive rigorous testing to meet 2) high EU safety standards. Let’s face it, at some point we have to trust other people’s expertise. We do it all the time when we use a microwave, get into a car, even use electricity. We can’t safety test everything. So we rely on the expertise of others to test the safety of a lot of stuff. I just don’t have the money to get a Festool air filtration system*. Even if I could put it on my credit card, the interest rates are killing me. So my low cost solution is to continue to use my shop vac AND wear a KN95 or N95 mask. And keep my shop space well ventilated. * The cheapest (CT 15) I can find on Mexican Amazon cost 16,529 pesos or $835 in U.S. dollars.

[@edwarddarlington7771]

People may not realize but dirty filters are able filter our more small particles than clean. If truly the aim is for health, then capturing more particles at the source is far more important than cost or convenience. Thanks for the video.

[@wittworks]

I agree on the orange cap! Cash grab!

[@richardsvacuumcenter]

Great content! Another idea is an old central vacuum canister unit. I come across old used ones all the time…so many that I often throw many away. The suction power is significantly higher since it’s using a tangential discharge motor rather than a flow through (like a a typical shop vac) and you can mount them on the wall. Many can be adapted to use a hepa bag as well. You can also port the exhaust outside which means zero emissions indoors!

keep in mind your old vacuum is super clogged with particles that are in turn filtering out those same particles, so its safer, but its also giving you much less performance compared to the new clean vacuum. festool is good but the price is just insane honestly

[@pilotalan]

I came looking for this. Yes, as particulate filters get dirty, they become more effective since the layer of dirt is essentially acting like a big layer of filter material. But that layer of dirt restricts airflow, reducing downstream performance. It's easy to filter particles. It's hard to filter particles AND flow large amounts of air. That's the challenge.

[@wittworks]

Well said.

[@chuckjohnson4048]

I bought the bag made of a material similar to thermal knit you find on jachets and vests. I put it over my cylindrical filter in my Rigid vac. No more 10-15 minute compressed air filter blow outs. The bags are washable and if you have a thermal knit jacket you can use both arms of it and make 2 bags. An additional item learned on YT was taking the shop vac bag and un folding onr end, opening it up to dump the dust out and re-folding the end and sealing that end with a 1/2 " piece of pvc that has been slit lengthwise and used to bind the folded vac bag end closed. I modified the slit a bit by cutting a "V" into the end of the slit and rounding the slit edges to keep the slit from cutting the vac bag. Works great, no more vac bag purchases unles you suck up a block that cuts your bag.

[@Ritalie]

What an awesome and very scientific video. Dust collection is surprisingly complicated. One thing I learned that most people don't realize is that rip cutting on a radial arm saw is perhaps the cleanest operation possible on a radial arm saw. The dust extraction port on a radial arm saw actually doesn't work at all during crosscuts unless you make your own special fence to suck up the dust being spit from the blade. But when rip cutting something magical happens, the blade guard is adjusted so there is almost no air gap at all between the guard and board and so about 95% of the dust gets sucked up into the blade guard. In conclusion, if you want a super low dust method of ripping medium size boards and medium sheet goods, a stock radial arm saw has built in dust collection and is orders of magnitude cleaner than an old fashion table saw.

Dear Sir, I bought 2 Festool CT33's back in 1999 when I first started using Festool tools. Just like your new machine it has a manual filter shaker which I've never used but purchased the LongLife cloth bags ( much cheaper in the long run over the paper bags) & have equally never changed the filters even though my Festool rep suggested it would be the best birthday present I could give to them. I have however cleaned the machines thoroughly, blasted them with a compressor to thoroughly clean filters & bag; those 2 machines are still with me & work flawlessly without missing a beat. There are more than likely some better extractors developed today since my last investment. For my next improvement I'll buy the new Metabo Bluetooth switch that allows any dust extractor to work with any tools; no need to lash out silly money for just a tiny feature. I have acquired four major different brands over the years which allows me to mix as & when I want. I've come to the conclusion that brand loyalty or getting the full Monty as far as system is concerned is sometimes nothing more than marketing ploy. I did fall into that trap much earlier on but with a little time searching & inquiring about other brands, one comes to the same conclusion that they all want you to only buy their wares naturally. I was going to buy Festool's Systainer dust collector but my rep told me that for sanding it's not really what it was destined for; more circular saws, planers & routers where the waste is much coarser. Being better informed allows one to use one's own judgement & make a wiser decision. I think in your case there is some merit in getting this set up as I am sure it'll pay for itself in a very short time. Best wishes with your new equipment. Kind regards.

[@christianratajczak3884]

I purchased a used Kirby vacuum online. I removed the bag and used the hose that’s connected to it inline to my large dust system that has a filter built in. Since Kirby has a turbine like system and bypasses the motor unlike conventional vacuums, allowing me to connect it directly to my large system that has all the filtration. The benefit of the addition of Kirby is that now I have really good suction for small tools as the Kirby moves smaller volume of air but at high velocity which is good for sanders and routers. This is where my large system didn’t do so well, as it moves large volumes of air but at lower velocities, especially when you downsized to a smaller hose for your sanders and routers or track saws. All this cost me under $50 bucks. And now I just have one place for all the dust.

[@JimPudar]

I'd try putting the meter close to where your face is while using the tracksaw. It doesn't really matter what's coming out of the exhaust port, just what you're breathing in. I'd imagine that the significantly lower suction on the old shop vac translates to a poorer extraction at the tool. You might be able to measure that with your meter.
