Pretty sure this is one of those videos that should be rewatched at least once a year, thanks for the advice and heads up.

It was COVID that showed me how weak my dust collection was. Last December I got COVID. No hospitalization but I was down for 3 weeks. When I finally got back in my shop, aka garage, I discovered an increased sensitivity to dust. I did the old "put the mask on, make the cut, take the mask off" thing and just a couple of minutes after taking the mask off, I found myself coughing. I put it back on and the cough went away. That's when I knew I needed to "up my game", as it were, when it came to dust collection. I was using a Ridgid 12-gal vacuum and a Dustopper on my table saw. I also have an RZ mask. I read the Bill Pentz stuff, as recommended by Stumpy Nubs. Between that and my increased sensitivity, I wondered if it was even a good idea to continue woodworking. Long story short, I added a larger dust collector (the Dust Right 750) and a HEPA filter and bag for my vacuum. I know it's not the ultimate solution for my small garage shop but it has made a huge difference, so at least it's a step in the right direction.

After watching the video advert i was still skeptical. But when i finally downloaded the plans kzread.infoUgkxZF0EMnrujZvqHhGkxiz559uIABJWR9TG i was very impressed. The whole plan was just as you said in the video. Thank you very much. I now have a large and valuable collection for my woodworks. This is great!

Walnut boogers are great for filling small imperfections in your projects.

Great video! One of the most useful things in my shop is my dust meter (Dylos). It helps me see how long the dust lingers in the air after I've turned a machine off. I don't take my PPE off until small particle count returns to baseline. I can also clearly see that the box filter hanging from the ceiling takes about 10 minutes to clear the air after an operation. Without the box filter running, it takes more like 30 minutes. I also notices that just sweeping the floor produces huge amounts of dust.

That's those little gem of information & tips that make reading comments so worth it

Talk to or read Bill Pence and you want to shout from the rooftops, “Fine dust is really dangerous! You need really good dust collection!” But most people have never heard of Bill so thank you, Jonathan, for using your platform to educate all your subscribers. Excellent video! I was thinking about one of those Bosch machines, but max CFM is 150 - inadequate for real dust collection. One thing I think is worth mentioning (for those of us who don’t have one of those awesome, huge canister filter with the internal filter cleaner) chances are you’ll have to clean your filter at some point. I keep around an old Bosch HEPA-rated household canister vacuum that I retired in favor of an upright. Great for cleaning filters and once I’ve done so, I just throw the bag away and put a new one in.

40 years plus doing woodworking and as most, neglect always protecting myself. Thanks for a great reminder!

Thank you Katz-Moses for always looking out for safety information as sharing as soon as it becomes relevant to you and the rest of the woodworking community. Cheers

Thank you so much for releasing these videos. It's really nice to see videos like this helping the entire community. I appreciate what you do, and I'll continue to shop at KM Tools! My wife knows exactly where to go for Christmas shopping this year.

Safety and Occupational Health Professional and prior Air Force Industrial Hygienist Technician here. Great video and just to add if you want to be super safe then you want to be clean shaven to get the best seal. If you are like me and love your sweet beard then invest in a PAPR (Powered Air Purifying Respirator). You will look goofy but you wear the cartridges on your belt that passes air into your hooded top. I use to fit test thousands of people on all different types of mask.

any recs for a consumer grade mask? I have a 3M half mask, Stealth, and a GVS Sprayer but not thrilled with any of them.

The number one thing that kicked me in the butt about finally getting proper dust management in my shop wasn’t my own health(it should have been, but we all think we’ll be fine), but rather my kids health. I moved from a home with a detached garage/workshop to one with an attached garage/workshop and I realized that the dust I was making was filtering back into the house. I still have a ways to go (gotta up my 4” stuff to 6”) but it’s significantly safer than it was just running a shop vac! Thanks for continuing to put out great safety videos like this! It’s helpful information for new folks, and a great reminder to those who have been at it for a while. Safety is number one!

Bill Pentz is the god of dust collection. I read his stuff more than a decade ago when I started to get serious about woodworking, and thanks to his advice, I’ve always prioritized dust collection. One of the most important things - and I got this from Pentz too - is to have a meter that tells you what the dust level is. That’s how I decide when I do and do not need a respirator. I use the dylos that he recommends.

Good stuff, but as someone who used to sell and test PPE, i'll tell you if you really want that mask to get down to the efficiency you talk about, you need to shave so it seals to your face.

Thank you Dr. Katz-Moses.

Merry Christmas Jonathan, I appreciate all you do. I hope you find strength and perseverance in the new year.

I just recently replaced the top filter/bag of my Harbor Freight dust pump with a Powertec filter. Massive improvement for only $30 or so. Knowing that what would happen is that dust would gather on the OUTSIDE of the filter, and be blown around every time the thing is turned on, I used a very large plastic bag, which happened to come with my Supermax 1632, and draped it ofer the top of the filter. It comes down almost as far as the inlets at the impeller. HF dust collector owners know what I mean... The result is that when I turn it on, the plastic bag only gets inflated a very tiny amount, so it doesn’t throw the dust like the old filter did. Rather, the output air goes down towards the floor. No dust ever gets directly on the filter itself, so you sort of eliminate the issue of gathered dust being blown around by preventing it in the first place. The Powertec filter is MUCH thicker than the original HF filter that came with the unit, which means that it doesn’t really ever deflate the way the original did. Highly recommended, and also highly recommended that you cover the cloth filter with some kind of plastic bag or sheeting to prevent dust from gathering on it.

I always thought I'm mostly safe, since I only work with hand tools and prefer scrapers over sanding. I moved a few months ago and was really surprised at how much wood dust was on top of the piping in the old workshop. A lot of it was from sanding guitar fretboards. Dust collection is now a big consideration as I'm setting up my new workshop.

Thanks bud for coming through with those blast gate templates! I'm planning on hard piping my small shop early next year and I want to get those blast gates built before that.

Great words of wisdom. I have been using an RZ Mask for months and didn't know just how good they were until I started making Christmas presents for my family out of cedar. With LOTS of cuts and thicknessing, I created a bunch of chips and fine dust. The RZ Mask kept the fine dust out...and I didn't smell any cedar until after I took off the mask. Another couple of steps I have taken were to get an upgraded MERV filter for my shop vac and made one of the box fan air purifiers with four MERV 13 filters. By moving over 2,000 CFM, it really captures the dust in my garage shop

2:46 I like how you’re holding back your laughter at the fart

Dude, you need to add air PURIFIERS in your shop. You mentioned 1 micron, but the filter in many modern air PURIFIERS are HEPA rated and go down to .3 microns... Logic is key! Thanks for all that you do.

I absolutely love your videos and and how informative they are. Keep up the awesome work and thank you for this gem. I’m in the market to upgrade my shop vac dust collection and this video has given me even more to consider.

Great video, thanks so I am upgrading the dust collection in my shop right now. I will definitely implement several of the suggestions here. Cheers.

Thanks for the quick explanation. I have chronic asthma symptoms due to wood dust (redwood is the worst, but plenty of others too). Now I have my respirator hanging on the door knob of my way-too-small shop and am not allowed to go in without putting it on first. The respirator I use is a standard 3M 6200/07025 half face mask with 7093C cartridges - these are actually p100 + organic vapor and acid gas rated. These cartridges are rectangular in shape and much lighter than the larger units but provide the same protection. I found that these allow easier breathing than the simple p100 rated cartridges (7093). Get protected! Worrying about whether you're gonna wake up in the morning is a drag.

Amazing blast gates! Thank you for the new files! Amazing customer service!

Always awesome content, so rich in information and facts. Thank you so much for all the effort you put into it.

Recently switched from a 16 gallon HD/Rigid vac with cyclone to a Jet collector (big tools) and Festool CT36 (little tools) and have been somewhat questioning the expense... this certainly helps alleviate some of those questions while also highlighting the need to realize that just because I have what I think is adequate collection doesn't mean I can make assumptions.

What a great coincidence, i have been thinking on improving the dust collection in my one car garage workshop. Thanks for the tips.

Good video. Many people in this space refuse to cover their mouths to save their grandmas life, so I doubt they will do it to block some dust.

Thanks for the info. I'm grateful that you do the research and condense it to a quick useful guide for us.

is incredible how many dust collection videos you have made prior to this without reading through Bill Pentz’s dust collection research.

Thanks for this ! Its actually what I’m working on now building a huge dust collector and then just for added safety I also am installing a wen air filter system. I to have realized how big of a problem all this really is. Great video very helpful!

I used a HEPA filter in my shop vac to start, but I’ve been spending my money on filtration before anymore ‘toys’. Thanks for reaffirming I’ve made the right choice.

Well done as always. Thank you for the great information. Keep up the great work.

One thing about dust masks: in industrial workplaces, they do "fit tests" to make sure that the mask fits properly and that no unfiltered air is getting past the mask. The bottom line is that masks don't work if you have facial hair. You either need to be clean shaven, or use a supplied-air (powered) respirator that maintains positive pressure.

Great video! My hobby wood shop is in an attached garage so I have concerns about dust infiltration into the house that my family might breathe. Bill Pentz 's website is a great resource. Those dust collectors with cloth bag filters need to be taken off of the market because they are dust pumps and not dust collectors. I wish more woodworkers would take their health more seriously, so I applaud you covering these topics in this video, particularly pointing out the fact that a hobby woodworker can do more damage to their health in a few hours in their shop than a cabinet professional would have in a year or more. Another great resource is getting a dust particulate counter, e.g. I use a Dylos DC1100 PRO to track air quality in my shop.

This was a great upload. I’m building my shop right now and this really helped with what I need to do. Subbed and thanks for the great information.

Thanks for this Vid. Comes at time when I was thinking of adding a shop filter to run. I just ordered on and I'll have it installed before the end of the week Also changing my bag filter to a pleated filter to stop the bag dust from coming on when I run the DC. Maybe the best video you have shared. I have allergies, diagnosed at age 4 more than 50 years ago. I've always tried to be smart with breathing "too" much dust. Got grand kids now and want to be around as long as I can. Thanks again.

Thanks for some great information! I just purchased a larger unit with a filter and will be improving my system ASAP!

Fantastic tips, Jonathan! Thanks a lot! 😃 Stay safe there with your family! 🖖😊

You’ve covered most of the info all in one place. Great job.

Thanks. You are good people, Jonathon.

Thank you Jonathan. So many people - men and women - like to be dismissive, which when linked to inconvenience leads to exposure of damaging particles and molecules. Only when someone comes down with a terrible physical issue or disease does one truly regret not taking the time and expense required to remain safe and healthy. The older I get, the more I fully understand that PPE gear, and the taking the time that is needed to use it, is worth every penny and minute. Don't wait for trouble to come - be smart and avoid it.

Thanks, man!! Very interesting subject!! Keep up the good work!!!

Jonathan, good points. I read Pentz's articles roughly 6 months ago. Being an analyst, I do not doubt his data or conclusions. 6" piping is the way to go, and 5hp collectors are necessary if you want to not have respiratory problems due to being a woodworker.

Good grief. This is a major problem for me.

Great video. I have *finally* gotten back into woodworking after a degenerated disc kept me out of it for 4 years, and I've been wearing my respirator with P100 filters most of the time. This is a good reminder that after the first cut is made, that respirator goes on for the rest of the day. By the way I think that's also where those walnut boogers might be coming from. Not so much the dust getting through the mask (if it's P100), but all those times we're guilty of taking it off, "making just one cut", etc.

Very eye opening video. Thank you sir for the video.

Thank you so much for making this video!

Getting my shop guys the RZ mask, glad you plugged your store 😉.

Such an important video, the dust always concerns me when it comes to woodworking.

thanks, good stuff. About to get a full bed CNC and I need to step up my collection game.

My carpentry teacher recently died of respiratory illness and I can tell you with no doubt in my mind that it is a direct result of his lack of dust collection. He'd been doing it longer than most people have been alive but to me this is the most important youtube video on woodworking and I really appreciate the effort put in.

Have dust filtration from Rockwell for my one man shop with the filter on top. Now getting shop filter and mask. Thank you for this!!!

Started woodworking only a year ago in a 10x10 shed, in Montreal winter so door is always closed. I bought one of those Shop Air filter and after a week of use the filter is full of tiny dust!! Made me realize how careless I was and now I need to find ways to get some Airflow outside without opening the door

Thanks, brother. It’s hard to find that line between good info and fear mongering. You did it.

Doode, awesome! I love how candid you are here. I think I've seen other people mention this but air filter comparisons would be cool; how quickly air quality returns to acceptable. But I think testing the leak rate of blast gates would be really interesting. Self-cleaning vs katz Moses vs iVac auto mated type gates.

I try and do all dust generating things outside and not in the garage. Being in the UK that only works for amateur woodworkers. I still collect the dust in the vaccum even when outside. I also wear a respirator rather than a paper mask

Topical. I was diagnosed with mahogany sawdust induced pulmonary edema just a week and half ago. I’m recovering now. Having to stay out of the shop for a while. Possibly forever. Don’t be me. Wear a respirator people.

Appreciate you sharing the knowledge!

Bill Pentz (via Stumpy Nubs) scared me enough to move my shop from my basement to my garage just for the airflow. It’s small and cold, but I can vent it with a fan.

Great info. Thanks.

Thanks JKM!

Bill Pentz's article is the reason I upgraded my dust collector with a nice filter system, bought better masks, and bought an overkill air filtration system.

Thank u! I started wood working a year ago and did not wear mask or have dust collection, I’m just now getting to the point where I don’t have to use an inhaler 4 times a day, my doctor tried telling me I had COPD but I knew it was from the dust (he’s not a wood worker apparently)

This is great info. We often get complacent working in a small shop thinking that the risks aren't as high. Having reminders like this is always helpful and welcome. Now I'm going to go all "Safety Police" on you. You mentioned in the video about blowing yourself off after you're done to get the dust off. It's worth noting that one should never blow themselves off with compressed air due to three major risks: 1.) Air embolism, aka gas bubble in the blood stream 2.) Ear injury 3.) Eye injury The best way to remove dust from your person is with a shop vac, which also reduces the amount of dust blown back into the air. Thanks again for keeping our minds on what's important.

Apparently, KZread didn't like the links and deleted the reply. The best I can do is recommend that anyone curious about the risks conduct an internet search for, "air compressor air embolism" and "high pressure injection injury". The latter can lead to compartment syndrome which requires immediate surgery, and if left untreated can lead to tissue necrosis. I will admit that these injuries are generally rare, but why run the risk when using a shop vac is just as effective of an alternative without the risk? This is the reason that OSHA, NIH, Industrial Safety & Hygiene News and multiple other safety oriented organizations strongly advise against using compressed air to clean yourself off, and advocate for using a vacuum instead. Stay safe in the shop.

I have some of your 6 inch blast gates and I love them.

Yeah... my false sense of security for my ears has lead to tinnitus for myself and my husband. I now have to wear the foam ear plugs for basically anything (removing an air tool will trigger it) and ear muffs for everything else on top.

I’m really good about dust safety but need to seriously up my game on hearing protection. I haven’t worried much about it but I realize I really should.

Thanks for the great information. As a safety person who worked in refineries, one of the big concerns was silica. After doing my research, it shocked me at the amount of dust just one cut can create. One cut using a masonry saw, with a standard kerf blade, produces enough silica dust for 10 years worth of exposure. That is when cutting a standard red brick. When I presented my class to employees, the looks on their faces were very telling. I could see them trying to remember how far back, and how many times they had done something like this over the years. I could literally see them trying to add up all the silica they may have inhaled. It really helps when you break it down Barney style and present it in an educational manner. I have a dust collection system that I will now go through again for a "tune up". I also use my shop vac, with a HEPA filter and my RZ mask. I will now be using the RZ more frequently after your reminder to not be lazy. Thanks again.

Great video, I missed a lot of these deep dive videos and have been really enjoying them. The only issue I have is the RZ mask...in my experience they give a false sense of security and do not properly seal around the face. There are gaps and the dust will take the path of least resistance. I get the argument of the best dust mask is the one that you will wear, but you open the video talking about a false sense of security. For me and the multitude of masks I've tried, if my safety glasses fog up then the mask is not sealed. But maybe others can get the RZ to seal without the flexible rubber material that's on the 3M masks for example.

Thanks for the video. To add to the debate... I bought a 'PM2.5 Detector Air Quality Tester Meter Monitor' through eBay which actually lets you see what your air quality is. I'm not saying these cheepish £35 detectors are perfectly accurate but it definitely monitors the changing nature of my workshop air. Knowledge is power. The particle levels went berserk when I did some pyrography, but my lathe work, outside sanding, does not.

A few things... 1. Get a laser particle counter if you really want to know what's in your air. Otherwise it's just conjecture. 2. Not all of us have the space for a full size dust collector, so shop vacs are the only option. These can work exceptionally well even for things like table saws IF you make the tool's dust collection enclosure very tight (but not completely closed off). You can use ductape or foam to seal gaps, use zero-clearance inserts, etc. Once you do that you can get close to 100% of the dust. 3. If you are going the shop vac route, make sure you get a HEPA filter for it if there is one for your model. If there isn't, change your vac for one that does. Otherwise you're just going to be spewing super fine dust right back in your air, unless you send the exhaust outside...

Great info, thx

@6:00 you can get HEPA filters and drywall bags for shop-vac (and size-compatible brands). I used those when I was doing heavy sanding, drywall, etc., and they worked very well together to keep the fine particles contained.

One thing I don't think you mentioned is that if you have any facial hair, and I do mean any even a hint of stubble, that masks and respirators aren't going to seal properly and you'll have intake that bypasses your filter. Personally I've moved onto a PAPR that has integrated eye and hearing protection for my PPE.

I'm glad you made this video. I was completely ignorant of the same issues until my brother forwarded me the Pentz article as I was designing a new workbench with internal dust (chip) collection.

The 3m 7500’s with p100 cartridges are excellent, last a very long time (cartridges only need to be changed if damaged or they become hard to breathe through, which takes a very long time). They don’t cost much - cartridges and respirator, which might last a year or so, are about $25 or so combined. Only caveat is that you need to make sure you have a good seal so you can’t use with facial hair.

Very thorough. I don't think you missed anything! Which is hard to do!

Thank you for a very important video. My father passed away this spring. He had been a hobby woodworker for as long as I can remember. I hadn't been in his shop in a long time. His shop was covered in dust. Thick dust was everyshere. It is a basement shop that is 2000 square feet with the shop in one corner. There was dust inside boxed up china that was stored in the opposite side of the basement. He had problems with breathing in his last years of life. He couldn't understand what was causing the breathing problems. He didn't smoke and worked in an office environment up until his retirement. I am not saying that the dust caused him to die, I am saying that some sort of dust collection may have prolonged his life or at least made him more comfortable in his later years. Now that I am retiring and moving some of his tools to my shop and getting back into woodworking myself, I see the need for air filtration as well as dust collection.

I’m personally interested in hand tools: are they safer for this? But it would be interesting to perhaps compare planers with HSS knives v carbide. Or, in keeping with your really great sandpaper video, how different paper and sander combinations do at collecting dust.

I just use my home’s air filters when I replace them every 3 months. They’re still in good enough shape to collect dust on the weekends. kzread.info/dash/bejne/nXxpo7Kwj7ayhbg.html

Just started being a subscriber enjoy your videos but I think today’s was one of the best thank you

Well, welcome my friend.

Your such a cool dude, much respect homie, solid content👊

Don’t forget that most respirators and masks are significantly less useful if you have any form of facial hair. Ideally, your should get fit tested by a professional to ensure you have a good seal around your mouth and nose. The exception to the facial hair is if you have a fine moustache.

big props on the "liquid death" you the man !

Life saving information. Another Jonathan Katz-Moses video going into my KZread save folder to reference when I need it 👍 maybe we could get a informational video on heating our shops? Watching this video makes me think forced air heaters are probably not a good choice....which is what I use 😬

Great video JK...M😄🙌🤘

Great info. I am looking for small space 9x21 dust collection options. Since there are a lot us in the smaller scale shops. This would be a of great interest. Thank you Jonathan !

This was a really good video. I think more people should be talking about the subject because it is easy to ignore or be lulled into a false sense of security by dust collection and the consequences of that aren’t immediately evident. As a fellow beardsman, I found that I have to use one of the full face gas mask looking things with active ventilation through a filter cartridge to overcome the lack of a tight seal on my face with standard respirators. I don’t think it’s perfect but seems to do pretty good even when working with finishes.

PAPRs are the best. More expensive than most other types, but the best. And getting sick from breathing fine wood dust is not cheap so they are worth the cost. I used to have a job where I worked in full-face a respirator all day. Trying to pull air through those filters all day and do hard work is taxing on your system. With a positive pressure type respirator, you can breathe easy because the inside of the mask is at a higher pressure than outside so no dust makes its way in. This means your lungs can work normally, which is way easier on you. PAPRs may (I don't have proof so I say may) also offer better protection for those with beards again because of the positive pressure maintained inside so any gaps or leakage around your beard will be offset somewhat by the air moving out at all times and not inward when you inhale. We were not allowed to have any facial hair that interfered with respirator fit (clean shaven or go home without pay). Everyone got fitted and had to test with each style and make respirator they would use.

I love my PAPR. My only gripe is I miss being able to wear over-ear hearing protection. Ear plugs are a pain to dig out and put back in any time I need to talk to someone

PAPRs are the way to go for the whiskered. But beware that there are tight fitting and loose fitting ones. If you are whiskered, you need the loose fitting.

Just realized the filter in my Fein Turbo I is NOT a HEPA filter. Will be ordering a new filter today. Thanks for the video!

I started getting serious about working on projects and after two weeks I noticed that PPE alone and the shop vac was not cutting it. So I purchased a Go861 collection unit from Grizzly. It’s crazy on how much fine dust it filters out.

My work shop is in the garage. So I try to do all of my cutting and sanding outside. One improvement I will make is adding a exhaust hose to the back of my shop vacuum. So the fine dust can be directed outside.

A good note from Bill Price is to place the actual dust collector exhaust outside if possible. In fact I wood turn outdoors for this reason since I don't have a great dust collection system in my basement shop

Awesome awesome awesome!!!! The best video I've seen on KZread about lunge health yet! Thank you so much . I have scarring on my lunges from formaldehyde and I have a yearly check for cancer. Could you please do a video on finishes and epoxy. Dust masks don't filter out the volatiles....you knead the charcoal filter. I've asked others to talk about it and they get defensive. I just want people to know and not have to live with the shadow over there head that I have. Thank you so much.

Watching this video made my chest hurt haha great stuff!
