It's for removing dust... potentially bad dust, the kind where you toss the 3M in the decon burn bag along with the rest of the stuff it sucked up... Off to the incinerator for all of it...

[@bobbg9041]

You want to have fun with your home made anamonotor, I did thins in Jr high school some 40 plus years ago with my science class, I kinda blew away my teacher And he was a diving instructor outside of school. The unit was set up to see who could pull up the liquid the highest on the scale most kids didn't raise the fuild very high, I almost pulled the liquid out of the unit before being told to stop. The teacher said he had never seen anyone do this. Now the trick is small bites of air rapidly not just one big bunch of draw, he asked how I knew this, I said it just seemed to make more sense I could lift the fluid in tiny gulps with less effort then try and fight gravity and air pressure. This brings up the point small bits of energy used but a lot of burst can do more then the large efforts you try to do all at once. So challenge your son to see how far up the tube you can pull the liquid, then blow his mind but don't tell him how you did it. You suck on the straw in tiny gulps rapidly let him try to drink it in one gulp. If you've made it right he can't pull the fulid to the top no one can. Hell your vacumes cant even do it. A vacume pump would and thats how they can draw down to 0 no atmosphere. If you've got a vacume pump make an air tight box Put in a speaker play music in it loud, draw the air out and the sound will stop even though the speakers still moving. Sound dosnt travel in a vacume Doing projects like this are fun and educational they also make you think. You build a better mind your son would benefit from it. And have fun doing it.

[@tomjudkins3799]

My shop vac actually gets more cfm than my makita dust extractor. You make a good point on the real differences being noise, form factor, and features. One thing you don't mention is the cheap vacuums spew dust when you so much as move them.

[@boogiedahomey]

The 3M dust extractor is actually a Starmix iPulse vacuum made in Germany and rebadged for 3M. You can buy pretty much the identical extractor under the Metabo brand for about half the price. There are also at least a dozen other HEPA level extractors from Bosch, Festool, Makita, Fein, Flex, Mirka, Milwaukee that perform comparably. Most are made by two or three OEMs. The big advantage of the high end ones for me are low noise, variable suction and tool activation. You definitely don't need one though, unless you make money building things, then the advantages become more meaningful.

how do you use a vaccum asa dust extractor while working when you only have 2 hands?

[@dell177]

i worked for the post office in the early 2000's repairing mail sorting machines. These machinrs get shut down and cleaned every morning and go through some tests to make sure they are ready to sort mail. Sorning mail by machines creates a lot of very fine paper dust. If you recall there was an idiot sending contaminated dust (ricen powder) through the mails that caused a lot of rethinking when it came to dust in the workplace. Beforehand the sorting machines were blown out every morning using compressed air and then the machines were vacuumes out to remove the dust. When I walk=ed into work at 2:30PM and there was so much dust that you could not clearly see things 500ft away (very large work floor). The procedure changed after they found unsafe materials were being sent through the mails to congressmen and other officials. Compressed air was removed along with the air hoses. machines were vacuumed out with new HEPA vacs that cost over a grand each. The result was the air was clean when I came into work but this was because we were not using compressed air to blow down the machines not just because of the HEPA vacs. i suspect a good quality vac would have done a good job at 1/10th the cost but I'm sure the HEPA was better,

[@tacticalskiffs8134]

Not at 1/10th the cost. You can get hepa filters and bags for regular shopvacs.

[@halsti99]

in germany, any dust extractor worth a damn has a rating. There are 3 levels based on the danger level of the material. - L for light danger, so any household dust. - M for construction work, so wood, concrete and so on. - H for high danger, so mould, asbestos or so. Since making filters is kinda pricy, most manufacturers put the good M quality filters into the L level dust extractors aswell, so the filtration is usually still good on them. Class M monitors airflow to check when the filters are clogged and automatically cleans them if they notice a drop. i think this is also where you have to ground the hoses to prevent electric charge buildup. Class H requires better filtration and much less dusty bag changes. If you have any employees as a blue collar worker, you are legally required to get at least a class M extractor, but for hobby woodworkers, a class L machine for around 100 bucks is probably good enough.

[@tharemyhopkins5873]

As you mentioned, the 3M sander and paper make a big difference, regardless of vac. Ran a Makita with gold paper for years with a vac and would see fine dust everywhere in the shop, even with a separate filter running. Switched to extract sander and paper and haven't seen any since.

[@wittworks]

Good to hear! That was my hunch.

[@christopherberry8519]

We sand 1000's of plywood boards every year using Mirka Deros and Festool vacuum combinations for printing on. We have literally used EVERY net based sandpaper we can get our hands on and have a bunch of vacuums besides the Festool from WAP, NILFISK, AEG. We use the Festool for one reason - NOISE. The Mirka we don't use Cubitron Extract 180g but prefer the Mirka 180g as it has larger holes so it vacuums the surface better as the first sanding releases longer Fibers which the 3M doesn't cope so well with. We are also experimenting with turbo brushes as they really remove abrasive residue, dust and loose fibers - remember we print directly on the wood in the same room as we have laser cutters The result is that a good vacuum brushing between grits really helps your sanding. We also have 2.5um sensors monitoring the situation - when the bag is full, we see the numbers skyrocket because the airflow drops so much.

[@daves7775]

We purchased a couple of "Dust Deputy" (s). Hooked them up to a low cost vacuum - which we had installed a main bag filter - and then a typical round HEPA filter at the top of the wet/dry vacuum - covering over the floating 'wet' ball. It does of course only work on dry stuff; and I haven't measured the air quality - but the vast, vast, vast majority of stuff is deposited into the Dust Deputy; a fine powder into the cheap bag vacuum filter; and the HEPA filter seems to remain quite clean. And it was all fairly low cost - budget wise. And you can hook a dust deputy up to virtually any vacuum. I also hooked one up to my expensive wood flooring sander; going back to the vacuum - for almost 100% dust free floor sanding. [They've changed the design slightly - ours are all metal - but the "Oneida Air Dust Deputy" would still work. All power is from your vacuum - and I know the 'cyclone' seems to be lame - but believe me - it totally works.]

[@Krynn72]

I bought something called a "Dustopper Pro" from one of the big box stores and slapped it on a home Depot bucket. I was actually shocked at how much it collected. I thought it would be pretty mediocre because the shape is so much different than the internet's beloved Dust Deputy type cyclones. There's basically no dust in the shop vac itself except for the finest layer. The layer was as if it just sat in an abandoned attic and left open for a couple months and so a thin later of dust accumulated. So combined with the filter I'm quite content with this level of dust collection. Now I just need to build a cabinet for get my tablesaw so it doesn't just dump dust on the floor.

GREAT job as always Drew. I have a porter cable dust extractor that is tool activated and has a bag and HEPA filter. I have a similar extractor made by Fein and use both frequently, these are my sander extractors. I have 3 shop vacs with bags and filters set up for miter saws and router use , also tool activated. My dust collection system is a Jet 1.75 HP I think. The biggest thing I have done for my air quality is a ceiling mounted air filter. In fact I now have 2. Stubby Nubbs did a video on improving the function and I did that on my first one purchased a Jet. This ended up being a LOT of $. My next unit purchased a Wen for job site use originally is now also in my shop. I did all the same mods only using less expensive alternatives for the big cleanable filter. This would be an interesting test with your expensive ( divorce material ) meter. All I can tell you is when running them I have MUCH less surface dust on things in the shop than without using my “ Pretty darn good “ dust extracting set ups. Plus my heater ( Live in Northern Maine ) has a filter and I no longer ever have the clean the filter alarm go off. Without the air filter it did. I still use a dust mask on occasions but I feel OK not using one most of the time now.

[@glcglc123]

Sound levels are one of the reasons Iwould consider a more expensive vacuum. I wonder if we did all of the vacs a diservice by not using the hose that came with the vac. The hose can make a huge differrence in perfotmance and I would expect that each vac would have hose designed for it's specific performance curve. I would think that hose is an integral part of each vacs overall system performance. Thanks for the video.

[@Griffinwoodworks]

What I surmised from this experiment is, the 3m is ridiculously overpriced for the marginal difference between it and the festool, the festool would be worth it for a professional shop or very successful side hustle based on the motor quality alone, and the Ridgid I use for everything from dust collection to cleaning my truck with will do an excellent job for a hobbyist. Great video and info as always pastor.

[@wittworks]

Basically! Thank you

[@TruePoindexter]

eh... sort of. The 3M is priced that way because it has features for a professional auto-body shop that a woodworker doesn't care about. Specifically, it features automatic on/off for both electric and pneumatic tools. This is something even the Festool doesn't offer and is a big deal in professional auto shops where pneumatic tools are in common use. You're 100% right that it's way too much for a hobbyist - because it's not meant for a hobbyist. Honestly if you're a hobbyist and want an upgrade from a shop vac to a dust extractor with HEPA filtration the Fein Dust Extractors are a much better deal. The Fein Turbo I was a huge upgrade for me from a cheap shop vac with HEPA filtration and auto on/off for about $350. A huge savings compared to the equivalent Festool which comes in at $600 - $800.

[@5280Woodworking]

[@MatthewDouglas805]

Really fantastic testing and analysis. I'm a longtime vacuum tech, and your approach to testing these machines is rare. I would love to see each vacuum in a sealed "clean container" like a Sterilite tub and see how much the particle counter rises as you pick up fine debris like sheetrock dust. Awesome job.

I have an older Rigid model too and luckily my version does let me use dust bags. I use them and find they hold about 70-75% of the full reservoir without a bag. I love my Rigid --is super reliable and provides all of the suction I need. Plus the bag plus internal filter seems to do a great job keeping exhaust particulates out of the air.

1 minute in, and I'm literally saying to myself - "Finally!" Thankyou so much Wittworks, you're a star! 🙂This is something I've been hoping someone with the right resources would do, ever since I went down the dust extraction rabbit hole.

[@andymok7945]

I am just a hobbyist and I do not regret the Festool CT 26E dust extractor. Having variable suction power is important when you have a good sander. I use to have the DeWALT sander I had to stop every so often because of the fatigue from the vibration. I looked at both the Mirka and Festool sanders and went with the Festool. I did not like the paddle on top of the sander that was the power switch. Both were otherwise very similar in handling and comfort. Coupled with the Festool extractor, only a very small amount of dust was left on the piece that I was sanding. Having variable power comes in great here. You want to lower the power setting when sanding as you don't want the sander being sucked down when sanding as you going to be sanding the dust and pushing it into the wood, making more of a mess and less getting sucked away. I am not a fanboy of any brand. The best tool for the job. I have Makita, DeWALT, Ryobi, Bosch, Milwaukee and Festool. I don't like the price of the Festool products, but they are great tools.

[@tacticalskiffs8134]

The approach I take to woodworking dust is: 1) I preference low dust tools a lot; 2) I have mobile elements to my workshop, and save a lot of dusty work for outside. This is tough in a winter climate where a lot of people want to do shop stuff in the winter and play during the summer. 3) I have a Racal helmet/3M and those things are life changing. However, if you do a lot of sanding in a cluttered shop all the time you are not wearing the helmet, you will be eating some dust. This is why 1) and 2). I also have a Shopvac with HEPA and bag, a dust extractor, and an air cleaner. 4) I recently bought a leaf blower for the yard, turns out it blows dust out of the shop like nothing else I have seen.

I use my shop vac, which gets cleaned frequently, especially when sanding. I wear a mask and use a homemade box fan filter with a K&N filter for additional filtration. No fine dust in the morning on any flat surfaces. Works wonderfully for me. Thanks for the video.

[@stephanmunro3658]

Very nice video. I normally buy a new vacuum for the house and take the old house vacuum to the workshop. But the mini filters clogs up very fast during sanding. To stop and clean that filters, is the problem, I can literally see the dust in air, even if I clean it inside my dirt bin. Point I want to make, I bought a Hazard L vacuum the other day, with an manual push button to clean filter, the issue I found during use... The air coming out of the machine, is almost 60 degree downwards. Blowing all the dust what was lying on the floor, into the air. The reason I'm saying 60 degrees, it is between 750 - 1000mm away from the vacuum. Luckily I always keep my floor clean, but imagine you don't.... How much dust will be flying around in my little workshop. ... Very interesting data/info you showed.

My vacuum system is made up of two different shop vac, (and old rigid and a Shopvac), and I added a dust deputy on each one all housed in carts with a baffle system to knock down the noise. They work pretty well. I also have an overhead Jet air cleaner. Been using this system for years now I have been really happy with it. I agree in a professional shop a higher end dust collection system is warranted, but for my shop what I have does great. Thanks for the video and the work.

[@CoreyShockey]

I'm not going to lie, there was a point where the number crunching made my eyes glaze over. I even started to second guess my "evil green" dust collector. But then I remembered how much I like knowing it mates up perfectly to the other Festool tools in my shop. So I have to agree with your summary. As a hobby level woodworker who occasionally makes a few bucks, I didn't need that level of tool, but is sure makes life in my shop more enjoyable.

I agree with the conclusion... I have the Ridgid shopvac (and believe any homeowner should have one) and the Festool 36. I used the Ridgid for "dust collection" for about 15 years. I like the Festool much more. It's a lot quieter, has some great features, AND, on the Ridgid, I had to clean the filter almost daily. I think it's been at least a month since I cleaned the filter on my Festool (and I checked yesterday and it's still very clean).

Another great video / comparison. I was quite happy with my Ridgid vac with Hepa filter and bag upgrades using my 3M Extract sander…but I was getting nailed with static electricity here in Colorado at 7600ft. I even tried an “anti-static” hose. No joy. So I went with the Festool MIDI as it has the cloth coated anti static hose and is grounded. This is after contacting 3M and their tecs could not confirm anti static properties other than the rubber coated hose. Using a 3D printed hose adapter on the MIDI to the 3M sander made the system a pleasure to use now.

I use the 3M sander and mesh sanding discs, and the dust situation is dramatically better than when I was using a Bosch sander and regular discs. I also use a Ridgid 6 gallon shop vac with a HEPA filter and HEPA bag that are made to fit the Ridgid, as well as a Dustopper dust separator. With all of these, there is almost no perceptible loose dust from sanding. Having said that, I also have an overhead dust extractor and I always wear a respirator while sanding. I already have breathing problems and I do not mess around with this kind of thing.

[@galtthedestroyer]

Thanks for the update.

[@ibarskiy]

Well, for sanders, I think most people even turn down the dust extraction strength at least on Festool / Festool combo anyway so all that extra suction is not necessary there. In other applications, though (e.g. saws, routers, etc) its very handy. So the choice of tool could well be impacting testing results (like you said, once you reach the minimum threshold it's good enough, maybe). And of course, the creature comforts (bluetooth remote, bluetooth battery operation for the cordless saw, etc) can't be beat.

[@gdreclaimed5442]

I use the 3M sander and matching paper mated with a cheap shop-vac. The difference is that I have the vac mounted outside in a box with the exhaust port of the vac blowing out into the yard and the hose running through a hole in the wall. My shop is small (only 13 x 21) so I just have about 30' of hose attached to it coiled up under a bench. I find it works very well and you can barley hear it run! I actually keep my shop cleaner with this setup because I don't have to don ear protection every time I turn on the vac. Also, because a shop-vac does not move a high volume of air I don't notice it pulling much of the heat out of the shop in the winter (I am in Michigan). This was a great video! thank you for confirming my suspensions!

I would definitely be interested in seeing the difference in dust control between the Extract ROS and paper vs. a Makita/DeWalt/Ryobi ROS with like… Gator paper. Maybe even change it up and use the Gator paper with the Extract sander and the Extract paper with the “Big 3” sander. I’m also curious about the effect that a cyclonic-style dust separator has on the shop vac performance. I have a sneaking suspicion that a decent shop vac with a cyclonic separator with the Extract paper and a halfway decent ROS would come very close to something like a full-out Festool setup, for a fraction of the price.

[@daifeichu]

You talked about this. Long lasting reliability. I've had two 6.5HP Ridgid shop vacs die on me. I bought a third one but I made a new Thien baffle and this one has a small door that I could slide open on the top when I'm using the thinner hose for my sander. This door reduces the pressure a bit so that the shop vac isn't as stressed. I think this has made a difference in 'lastability' and it still does an okay job of getting most of the dust but a mask is still needed.

[@koyzumie]

Thankyou for your work! Loved the video

[@mattkoke1]

I bought my festool after burning up 3 ridgids. 2 of them in a year. Ridgid covered them with their warranty but its still aggravating. I enjoy using the festool and on the few jobs ive done its much easier to transport. The BT control is a cool festure as well.

If I did a lot of sanding and was worried about dust to the point of a $1500 shop vac --- then it seems like a cheaper and more effective approach would be to have whatever vac, a sawdust separator - and the final exhaust from the vacuum system being ported to outside the shop. Then minor differences in fine particles in the exhaust wouldn't really matter.

[@TwoHeadsBrewing]

I think you're on to something with the sandpaper. I have a similar Ridgid shop vac, although the larger version, paired with a Duststopper cyclone. When I switched to the 3M sandpaper, there was a noticeable difference in the air quality in the shop. It's simply incredible how much more dust it collects and also provides a better finish.

[@dansarfert3585]

How do you change the amount of suction with a shop vac? That's the feature that separates a dust extractor from a shop vac since it lets you ensure you're not just adhering your sander to the surface of the workpiece.

[@jd1399]

you can add hepa to your shop vac an also a bluetooth button/outlet. or the outlets that lets you add the shop vac with a 3 sec delay. thats what i have. turning the tool on, turns the vac on. with the bucket cyclone to make the hepa bag last longer

I think this proves the sanding tool is integral to successful dust extraction. I’ve used both cheap and high end extractors. The high end units are just nicer, quieter, and like it was said- more enjoyable to use.

[@kzookid2051]

Great video & information. This gives me the idea of hooking my shop vac to a longer hose with a trash bin as the container outside.

[@marshallmurrell4583]

I use the Oneida cyclone hooked up to a Ridgid shop vac. The shop vac does use a bag, which saves filters. Most of the dust is caught by the cyclone. I rarely have to change the bags in the shop vac. The limitation is the tool itself to which the hose is connected. The miter saw, as one would expect, is the worst. The router table and the table saw also produce quite a bit of random uncaptured dust. In order to mitigate the dust in the air, I built a mobile filter cart using a squirrel cage from a residential hvac system and standard hvac filters. That device captures a lot of dust. It is a fairly high cfm device. I also wear a 3M particle mask anytime I'm producing sawdust. For a hobby, garage-based woodworker, I feel fairly well protected.

I have a festool ct mini. Its a great little dust extractor. I just wish the extractor was bigger, and had the hepa cleaner function, as well as the bluetooth option. But for what it is, its p good with most of my tools.

[@EvanDunville]

Great Video! While i haven't set it all up yet i plan to connect my shop vac with hepa bag in line with a small dust deputy cyclone and a system of central vac pipes to run the High pressure, low volume dust collection system in my shop. I intend to use it for general cleanup, a swing arm hose for handheld power tools and hooking to the dust port on my miter saw and a dust hood on the table saw. That is in addition to my 4" dust collection system, the air cleaners and masks!

[@wittworks]

Cool idea. Big fan of DD

[@SamWanamaker1]

This is pretty much the setup I have and it works great. Also added the Hepa filter.

[@davinohms5178]

Very awesome video drew! Nice work. Eye opening for sure

[@wittworks]

thank you! too much work!

[@justinthames940]

Had my shop vac blow out from sanding. Just couldn't handle the long run times. Upgraded to the festool CT 15 same engine as the midi with just a 4 gallon collection and no fancy static hose .. but for 400 bucks it's an amazing deal for HEPA filtration and does a great job

[@outofcontrol4499]

The U-tube manometer is old school but it is as accurate as the ruler. BUT this rig stops the flow of air through the machine (with the exception of suction leakage). The condition of filter or fill in the bag won't have any impact. Without flow there is no pressure drop through the filter. A better (but much more difficult test) would be to measure suction static at varying flow rates.

[@Version135]

Seems like a good place to leave this story. There was once a person who needed to do some drywall work and used an electric sander. Soon that person couldnt see across the room and realized his error. That room took months to get back to a clean (breathable ) state. That room was the master bedroom.

[@scorpianspirit5124]

I'm already subscribed, but I did like and I'm commenting... ;-) You did a great job on this video! In my case in a small room shop I had the luxury of mounting my inexpensive Wen dust extractor fan on the outside and just blow the dust and saw dust into a barrel. ( I live on acreage) But I do occasionally use my leaf blower to blow dust off the side of my house, but hey it keeps it out of my lungs. ;-)...Well done ! Cheers from Utah.

[@hansangb]

@14:30 LOLOLOL. that was awesome. And it was a very thorough test test. For a second, I thought Mathias was collab'ing with you! And @18:30 I was about to type that the 3M sander and xtrack/cubitron? was efficient enough that the vacuum wasn't the limiting factor. I don't know how loud the 3M/Festool is, but that RIGID vacuum is loud as hell. So that's another risk factor. As someone with hearing loss (did stupid things in the Army) loudness matters too. I use the Quiet DeWalt vacuum, Fein vacuum (both with filter bags) and it works great. The DeWalt goes to the bottom of the SawStop and the Fein goes to the top guard/dust-hood. Works really well.

[@tomhorsley6566]

My cyclone dust collector made out of a couple of home depot 5 gal buckets and various PVC and 3D printed bits works surprisingly well with my cheap ridgid vac. I only use the (antique at this point) table saw for a couple of cuts a few times a year, so it is fine for my purposes.

[@Danko88]

now I am interested in how the shop vac performs with a dust deputy vs with out :)

[@peterlaughlin930]

Really good video informative. I have basically a shop vac but I also where a a mask with Filters when I sand

[@tullgutten]

Always use dust bags on shop vacs unless using it for water. Bags are cheaper than filters and will keep the air flow and filter performance better for longer. Also the vacuum outblow port design changes a lot how the total dust gets. I have a cheap one, works great but the outblow and motor cooling air flow blasts dust up from the floor behind it

[@tpaulsmith7194]

lol at the brain on Drew! Very informative. Thanks! PS….the new Makita track saw “plug” works great. Thank you.

[@riba2233]

Great video!

[@flboy77]

Nice video, Drew!

[@nickmagma7745]

You make such good videos that it´s ridiculous. Keep up this great work!

[@robertbankhead8661]

Well done, very well done! Thank you for your analysis and conclusions. BTW, I bought my Xtract in the initial release, (half price) I have 6 - 12 gallon Rigids as well.. Thanks again

[@thesandman775]

Would be interested in this test with a Ridgid vac that accepts a hepa filter and bag. I've used that type of system while sanding skim coated drywall with great results, but it'd be nice to have objective numbers to see

[@billrobinson198]

I put two hoses together and put the vacuum outside when I vacuum. It's quieter, less bulky in the shop and gets all the particles out of the shop.

[@Stan_in_Shelton_WA]

using a collector before the shop vac will help it perform through a large project of long day. Even Harbor Freight has a pre collector device.

[@DanielJo-dl3sl]

I can’t see if anyone has done this, but do you think you could make an equivalent to the Festool cyclone by putting a dust deputy in one systainer, and use a large systainer as a collector underneath it for collection? Then you could stack on top which can’t be done with an Oneida.

[@frenchyroastify]

I found the Ridgid vacuums to be quite noisy and so so built. I switched to Dewalt "cheap" vacs: better wheels, quieter, better switch, washable filter, and just better design and construction all round (I recommend upgrading the hose though). At work, I do use the Festool Midi which is great.

[@joycejenkins0502]

Love your videos! I am a hobbyist furniture refinisher. Since I have no garage space, I use my basement. I want to be able to sand indoors, in my basement, without spewing dust everywhere, so I’ve toyed with the idea of getting a dust extractor, but the price is just not practical. Thanx for the comparison! It was very helpful. Did your Festool survive the unexpected dousing? I felt your pain. Ughhhhh.

[@joekent6576]

Your supervisor didn't make kool-aid for you. You just stole his refreshments from him. You're definitely getting a write-up.

[@wittworks]

Hahaha

[@chrismccracken]

One thing you didn’t hit on in the video which is super important is noise levels. I’ve found my relatively quiet Festool dust extractor is WAY less fatiguing to be around than my old shop vac due to the noise level and frequencies (even with OSHA-compliant ear protection). It’s worth the money to me for that reason alone.

[@scottanderson3577]

I have not had trouble with sawdust but I would say that drywall dust and concrete dust will most certainly kill the motor bearings in a shop-vacc. in high volume.

[@bryancampbell8942]

Would love to see your thoughts on the record power camvac. They seem like a great option in this price range

[@fredmeyer3063]

Thank you for this very informative video. I wonder if dust extractors use more electrical power than a shop vac?

[@spiromifsud1226]

Solid video. Keep it up!

[@hippie-io7225]

On-the-cheap: (approx $30.00) I put a high quality 20 x 20 in filter in back of my 20 x 20 in "Big Box" , box fan. My particle counter has shown that this very inexpensive set up, does quite well at removing pm 2.5 particles.

[@EOTE_TX]

I just invested in my first HEPA vacuum for sanding as my 20 year old Craftsman hooked to my Makita orbital sander left the table white with sawdust after sanding a few wood panels. I decided to buy the new DeWalt Stealthsonic vacuum for $139 at Lowes. Using the same sander the table is almost dust free after sanding the same amount of panels. I'm not saying its the best, I am saying that it works for what I need.

[@josephgdraper]

I have the same Rigid shop vac. As-is it can't be used with a bag. I bought some black ABS plastic DMV pipe and used a heat gun to modify the inlet so I can use a bag. I also added a HEPA filter that can be cleaned with water. I hook it up to Rockler Dust Right dust separator with saws (jig, scroll or table) and sanders. I'm transitioning to using a Grizzly dust collector and cyclone separator with a HEPA filter plus a Grizzly shop air filter (I bought it before they started selling their HEPA air filters). I wear a reusable mask (RZ). If you know Bill Pentz's story, you may understand the health effects of extended exposure to saw dust. When I saw you cutting all that MDF with the DeWalt cordless track saw without a mask, it made me cringe.

[@mtbdeli9018]

Did you compare the two air quality/particle meters? I'd be curious how the cheap one did vs the expensive one.

[@StoneyMeyerhoeffer]

I got my xtract extractor for $950 shipped. If the price has jumped that much, I thank my good fortune. I probably would not be a buyer at $1400, but not because it isn't worth it. I love it. It is permanantly paired with my xtract sander. The only better sanding experience might be SurfPrep. My Bosch miter saw is permanently paired with a Bosch VAC090AH extractor which I think I got for around $700 shipped. I like integrated solutions and I don't like disintegrating them for other uses. The Bosch has a thumper to shake the filter which helps a lot. The rest of my shop is on a central unit. I have a Fein Turbo II relegated to "shop vac" duty. It is in the garage for household tasks and the like. I don't know better value when you step up to HEPA compliance. $400 get's you there with a superior unit to everything else at that price point. It just still isn't the Bosch, Festool, or 3M. I have never owned or used the Festool, but trust your results. If I were looking for a shop vac, or HEPA wasn't important, it would be the Fein Turbo I. You can't get a better shop vac at the price point in my opinion.

[@Ariccio123]

Oh you know what you'll get a kick out of? You know what works really well for sucking up ultrafine drywall dust? My Dyson v11 outsize on boost mode. As long as you don't hold it upside down, virtually none of it gets through to the filter. After going through several months of renovation, all I've ever had to do is just tap the filter against a tree whenever I've used it upside down. It's absolutely wild. Not a contractor vacuum at all. I'm considering buying a used cinetic model to use for this kind of stuff in the future!

[@baddog4347]

You have some of the best videos on utube 👍

[@wittworks]

You’re too kind. Thank you.

[@noahkatz9616]

fyi theoretically flow restriction from hose differences, filter cleanliness, etc has no effect on static pressure. That's because there is no flow to develop a pressure drop across said restriction. Presumably the fact that you did measure small differences was due to leakage, so that there still was some airflow.

[@nathanswoodcrafts]

Great video Drew 👍🏻

[@wittworks]

Gracias

[@zanepaxton7452]

There’s an issue of being appropriate to the intended use of a vacuum. I *invested* in the high end Festool CT 36 E with the CT-VA 20 to separate out the chunky stuff encountered in remodeling. Yeah, it was really expensive. The Festool extractor is a fine tool for dust when attached to something like a sander. In remodeling old houses there’s toxic materials so I felt good about the investment. But, the small hose easily gets clogged when vacuuming up the chunky crap we see in remodeling deteriorating old houses. It doesn’t have the high CFM that I needed either. So, I’m now looking for a cheap shop vac for remodeling that has the bigger 2-1/2” hose and higher CFM. It’s either the Harbor Freight biggest Bauer shop vac or the rigid at Home Depot for the chunky remodeling vac while the Festool deluxe dust extractor is dedicated to sanding. The right tool for the right job!

[@roberts5erauedu]

Have you heard of the Karcher nt40 I got mine just under 400 bucks...it has auto clean variable suction and a couple other cool tricks...I strongly suggest everyone look in to them. I did a lot of research and seemed like the best bang for the buck if not best overall...did I mention German made

[@thenext9537]

You have 47k (yea yea 46.9 right this second) subs, there needs to be 1,460,000 subs at least, I enjoy your work, and what you do and you've saved me a ton of time. K, bye have fun!

[@Smedleydog1]

The biggest reason to hook a vacuum of any kind to your tools is to keep the shop clean. If you are worried about fine particulates in the air that normal vacuums may not remove, get a respirator and/or get a longer hose and put the vacuum outside of your shop. Save your money for more or better tools.

[@ScottClevelandmi]

These are the resolute I expect based on years of experience with my “orange” vacuums. I always use bags. Makes the vac last for years! Using them on construction sites they last about 8 years. They are excessively noisy.

[@slanwar]

My shop vac has a bag and the filter has a “sock” used on pools, would be interesting to see if this setup is better. I never have to replace my HEPA filter since I use a bag and the sock.

[@wittworks]

I like the sock idea! 🧦 💡

[@RUM123]

I've noticed, after a year with my Festool 36, that my shop stays cleaner. When I was using a Ridgid shop vac, which I have 3 dispersed around the house, I noticed the next day that there was a fine layer of dust on most surfaces. While not anywhere near a scientific study, that sold me.
