Industrial Hygienist and woodworking hobbyist here. You did a great job, overall. A few comments: Most importantly, if you have any respiratory conditions or other serious health conditions such as heart disease, consult your doctor before using a respirator. Respirators put a burden on your body when you are wearing them, and not everyone is able to wear one safely. At the end of the video, you show a Powered Air Purifying Respirator (PAPR)...you referred to it as a full-face respirator, which isn't quite accurate, so if someone is searching for one online, they should look for a PAPR...but regardless, this is not only a good alternative for bearded people, but also might be a safe option for people with respiratory or other medical conditions. You spoke a few times about vapor cartridges for finish vapors. It should be noted that these are not all made for the same kinds of vapors. So when buying cartridges, you need to make sure you buy cartridges that will absorb the chemicals you're working with. For spirits-based oil finishes, Organic Vapor cartridges are what should be bought. Lastly, for God's sake, CLEAN YOUR RESPIRATORS. Like, regularly. Respirator manufacturers make special wipes for cleaning, which are convenient. But just soapy water (dish soap) followed by a rinse and hang to dry works just fine. This is only for the plastic/rubber parts, not the filters or cartridges. Oh, and for your non-US viewers, masks marketed outside the US will likely not have NIOSH ratings, but should have ratings from the corresponding health organization in their country.

Assisted a friend re -enamelling the hull of his yatch. Sanding first. No protection. He said it wasn’t necessary and I accepted this. Had respiratory problems next day which eventually cleared. Scary and never again. Take responsibility yourself. Excellent video. Very informative.

Safety squints and holding your breath don’t cut it?

You can't warn people enough about the dangers of wood dust enough. My Dad was a carpenter for over 40 years never smoked or used any form of dust protection. He developed dust related copd was forced into retirement and died a horrible death 4 years later.

I don't like most you tube videos. This guy is awesome. All killer, no filler. I'm subscribing

i'm a beginner - this was SO well explained. thank you!!!

Always straight to the point in a very effective way, not wasting time.

i bought the stealth mask on your recommendation, as someone who wears glasses it’s invaluable and now i can see what i’m doing.

Really good to see you back, James.

These videos are more important than learning the craft, shame I did not watch this 40 years ago and who knew they used to filter beer with Asbestos...

I`m almost 80 & finally broke down & bought that Trend. It feels good but now I`m trying to build the habit of putting it on, which is taking time so everyone do it

Thank You. Been concerned with dust for years!

So glad to see your healing nicely, thanks for this video and the links defiantly need to upgrade me dust mask.

thank you so much for this video.. the timing is perfect

Glad to see you getting around on. Hoping for full recovery soon!! This video is perfect timing!! I really needed this. Thanks for great, informative videos!!

Stumpy, I have learned so much from your video's. I can't thank you enough for all the information you provide.

Thanks for doing what you do, making these videos for the good of the rest of us :) u seem like a real genuine guy

Dude thank you so much for talking about things in detail, instead of leaving stuff to figure out like so many other people do on KZfaq. You saved me so much time on research, you rock🤘

Pleasantly surprised at the good discussion on respirators. One minor correction - fumes heated solid particles that eventually will condense out from a gas phase to a solid...(metal particulates condensed from vaporized metal fume from welding, etc). vapors are gasses that typically stay in the gas phase at room temp. Hence the black organic vapor cartridges needed when using finishes, paints, etc. which use activated carbon to capture the solvent vapors.

Thanks for the clear, easy to understand information. I need to up my dust mask game & remember to always wear the dang thing.

Added the Trend mask to my Christmas list after a previous video where you covered it. I do use the 3M 2 strap N95 masks and while not great I can tell a huge difference at the end of a long day in the shop vs when I didn't. Glad to see you're recovering and back online. I was close to getting one of those blades for my grinder to deal with some small stumps on my property. Not now.

This was the most comprehensive and easy to understand explanation of dust masks and respirators I have ever heard! This after 20 plus years as a safety professional...

I bought the Trend as you reccommended in a previous video. Love it! as a guy with COPD I need to protect what I have left.

The shop isn't the only place to wear a mask; I acquired asthma while working with outdoor equipment that raises dust.

Wonderful overview of the subject! Thanks for your detailed and accurate reviews of these products - you make us informed with minimal need to do the research. Keep it up! Thanks.

thanks again Stump Nubs, once again a top video. its so nice to have these videos, specially for people like my self who cannot afford to go to college to learn. i have learnt a great deal about wood work from you.

I’ve been wearing various types of masks and respirators (half face and full face) for years, and I have to say this is the most informative, no fluff, no nonsense educational video on respirators I’ve seen in a long time. 👍🏻

This is a very well articulated video. My husband installs floor, sands, stains and finish and we have a small wood craft business. I’ve been telling him he needs to invest in a good respirator. I’m about to buy him some of these. Thank you!

“If it fogs your glasses, it’s leaking”! Fair statement, good thought. Mine fog all the time.

Word of advice, 25 years ago I ran a wet spray department. Back then carbon filters were only good for 48 exposed hours, so make sure you read the provided sheet. Also, you need to clean the inside of them regularly. The idea is that you protect yourself, but you have to maintain them properly.

Superbly succinct - I’m off to buy one now - thank you for taking the mystery out of it 👍👏😉

Thank you! This is one of your most valuable videos to date. Tons of useful information. I've used the 3M for years but now I'm ready for a more compact model like the Trend for particulate protection thanks to this video. I build RC airplanes which are, of course, mostly balsa. Balsa is a nasty wood that has tons of silica in it. When I was young I fought the balsa dust with a cold one. Fortunately I know better as an old guy.

I got a Trend Stealth for Christmas and it works great. Thanks for the advice.

I've been using the Trend face shield whenever I turn for a couple of years now, and it's probably my best safety purchase since I bought my logging chaps (even though I don't have a beard - lol).

Thanks for sharing with us James!

About time to upgrade my dust masks. Hope your recovery is going well. It sucks to work hurt, but we live and learn.

Had a Trend Stealth Mask for about 6 months now and I'm really pleased . I have a small face and other styles really are obtrusive for me. It's easily washable too.

This was fantastic. Thank you.

I'm happy you pointed out (without actually saying it) that RZ masks are not an appropriate solution for dust protection. I see too many woodworkers relying on that mask, when it isn't even Niosh approved. Really great review of the options out there!

I bought a 3M AirMate PAPR on ebay it was open box and I've used it a lot. Full hood supplied air and uses a hepa filter. Best $65 I've spent.

Yes! Another woodworking KZfaqr that understands the health hazards of dust! This is a great contribution to our community. Thank you. Scott

Thanks James, great review of an important safety topic. I think I have at least one of all the respirators on your bench. Just received Trend's Airshield Pro a few weeks ago. Great improvement over the face shield/respirator combination I used at the lathe for several years, comfortable, zero fog and deals with the beard I grew last year when I retired. Thanks for sharing and Cheers from BC

Viewed a lot of mask videos - and your presentation was one of the best. Great service and please make more. Thank you.

Another useful and professionally created video! 👍🏼👍🏼

I have the Trend Airshield Helmet. I also have a respirator but I do not know it's capabilities. I'll check that out the first thing in the morning. Thanks for the safety update. I hope your hand is recovering nicely.

THIS IS FANTASTIC INFORMATION FOR US BEGINNERS...OR "WANNA BE BEGINNERS". Thank you and I see your healing well darling! I was going to get the future looking mask. I will get your recommended ones now. I have all winter to get them. I am hoping to have the garage ready to go by spring.

Thanks for the great tips on what type of mask to use and when. Much appreciated.

Great job with the tutorial. Before I retired, I was certified at the mine to fit test miners for respirators. I had a few interesting conversations with bearded miners. A couple of things - when you wash your eq, make sure to use the cleaner designed for it. Regular dish soap will degrade the material and make sure it is dry before storing in a sealed bag.

Incredible Video. Thank you so much.

Great info as usual- thanks. I hope your injuries are healing well, thanks for sharing that too!

Stumpy, I have been watching your channel for a year now, along with other wood working channels. I must say you consistently give easy to understand, valuable information every time I watch. From one Michigander to another great job 👍(btw I live east of the thumb, right here ✋ 👈)

Thank you, sir! Awesome and informative video. You’re a life-saver!

Great video. I learned a lot about respirators.

Gold ! Thank you.

Great video. I had a charcoal filter with a particle filter mask I used while painting cars. I changes the particulate filter as needed (tough to breath) but I used the charcoal filters for over 5 years. Sometimes the over spray would be so heavy that it burned my eyes but I never smelled the fumes. I finally changed them just because and I never had another set last 6 months.

James, Thank you for alerting people to this very real danger. I was a construction safety officer for 25 years, started out as a safety compliance officer with Oregon OSHA and then went into the private sector for the remainder of my career. Please allow me to share a couple of the finer points of respirator use. Any filter that is exposed to normal outside air is working it doesn't matter if it is HEPA or Organic vapor or what have you, it is working whenever you pull it out of the bag. It should always be put back in the bag or bucket or coffee can when you're done with it. But placed in such a way that the rubber facepiece is not deformed in any way. The last thing you want is to pull it out and then find that it doesn't fit right anymore. Additionally, you should separate the filters from your mask and place them in another bag. but before doing that take a piece of duct tape and place it across the inlet side of your filter. This will prevent any particulate from contaminating the inside of your filter after it rolls around in the secondary bag. I usually seal both sides of my filters. The secondary bag also keeps the inside of my mask cleaner than if I had just thrown it all into one bag. Lastly, the use of full-face masks is more desirable than half face. It is easier to seal across the forehead as opposed to the bridge of the nose and gives good eye protection from anything lower than a high-speed projectile. Respirable dust is the dust we can't see, and that is the dust we need protection from.

Thank you, timely information for me starting out.

Short, informative and to the point. Well done :)

Great job James... most helpful.

Informative, succinct and well presented. The cost of high quality respirators pales in front of lung diseases or worst lung replacement surgery. So protect yourself by the recommended masks in this video. Thank you James for this safety tip .

This video was very helpful. Thank you such a educational video.

Thanks a lot man, you’re saving lives. Including my own! 🤟🏼😔💕👁

this helps a lot, thank you

your videos are fantastic, thanks very much for the info! hope your hand is healing well.

Outstanding video thank you!

Hope the recovery is going well. This, 'all you can do is wait' period is a real pain, I know. So as you've got a reason to go easy, enjoy it, you've earn't it my friend. :)

Extremely well explained Stumpy! Thank you! I am lucky, I have allergies and I use the N 95 disposable mask they fit my face really well. I buy them in bulk!

thank you for the video stumpy

thanks for your help

Such an informative video. Thank you! You've gotten a new subscriber here 🙂

This was very informative, James. I'm new to woodworking and a hobbyist. I have some paper filters and a beard and I don't use them every time. I have been shocked by how much sawdust settles all over every inch of my garage. And also how it clings to the metal grill and blades of my high speed fan. This helped me decide to get a better respirator. Thanks.

Thank you very much! was looking for specific guidance on mask choices & safety ~God Bless.

Another great, informative, episode!

Thank you for the great info. On the recommendation of one of your videos, I bought and almost daily use Isotunes ear protection, so I’m definitely gonna at least consider these.

Really good video--thanks. You're helping people stay healthier! A small point, but very important: When you show the 3M cartridge vapor filters with attached particulate filter, I can see the printing on the particulate filter through the filter retainer. According to 3M, the printed side is supposed to go on the INSIDE (toward the cartridge/mask), so what I should be seeing is the blank side of the particulate filter, NOT the printed side. I'm guessing that 3M gives this direction because putting this in backwards could compromise the filtration--so it's probably important to get it right.

Great video...Dust and hearing protection are the most important things in a workshop or jobsite, in my opinion. You wear safety glasses because something might end up in your eye, but virtually everytime any power tool is used large amounts of dust and noise are produced.

Really straight forward and helpful, best content on youtube, thanks man

well, i just learned a lot!!! thank you and good luck with the hand. doug

Very helpful.

Thank you I'm a multi task worker and now I know which one to bye

Superb video thanks - I learnt a lot!

Thanks dude . 👍💪👊

Good video, informative and well presented, like all of your videos :) Thank you!

Very useful and sensible. Hope your recovery is rattling along mate. Cheers James and Happy Christmas to you and all your viewers.

Great info James, I did not know those paper filters did not give 100 percent protection. Going to order a better one now.

Very helpful!

Thanks! Just started dabbling in woodworking. Built a workbench and totally had the “wood-boogers” after gobs of sanding without a mask. After watching this video, never again. I hope Harbor Freight sells good masks.

I bought the Trend mask that you showed in the video. It seals very well on my face, I have no beard. My problem with this and all other masks that I have tried it is uncomfortable to wear. It also interferes with my glasses, I wear trifocals. The Trend mask is the best mask that I have bought.

Great review, thanks!

Great advice! If I knew back then what I know now...

Thank you for this education. I gotta get me a better one!

👍 agreed friend!

Good video, thanks!

Great video. I put the Trend Stealth in my Christmas list. Thanks

Hey y'all! I'm a licensed asbestos supervisor in PA. If anyone has questions about proper PPE/Masks/filters and most importantly proper fit testing please feel free to message me. You only get one set of lungs, take care of them. Thanks for the video Stumpy, very good quality on the subject.

I have a beard and when I need filtration I use the Resp-O-Rator Dust Respirator I find it comfortable even under my full face shield and welding mask. Play Safe From Elliot Lake Ontario Canada.

Good job!

Thank you for not obscuring brand names with a cheesy piece of gaffer tape!

Great info 👍
