The most common topic request for Safety Week was dust and respirators. So here’s a quick review of the dust and fumes that can make our lives miserable in the shop, and why we need respirators for pro-active protection. And below you will find a links to the exact respirator setup I like to use: the 3m 7500 Series.
The link below is for large, but you can select a different size here: Small, Medium, Large. And don’t forget the upgraded pink filters and the special adapter.

Thank you for not naming this episode “Dust in the Wind”
Great information Marc. I know I’ve learn all that stuff at work years ago, but have forgotten it or never thought to apply it to what I do at home. I have to admit, I don’t use dust control nearly ass often as I should. Thanks a lot, very good reference material.
The manual covers a fit test that you can do at home. If you cover the intake ports and inhale slightly the mask should pull in and not leak. If you cover the exhaust and exhale slightly it should inflate a bit and not leak.
It is not as good as using the fit tester but it is better than assuming it fits.
I have a delta 2 stage dust collector and a 20′ long 6″ hose from Rockler (the new one expandable one with the grounding wire built in.
When I stick this sucker in my 10″ Powermatic cabinet saw I start getting little shocks. How can I stop this as I feel I am going to start a fire at the most and at the least its annoying to keep getting shocked.
Thanks!
Hey Marc,
You made a good point about proper fit and facial hair. I have to occasionally wear a respirator as part of my job. The NIOSH fit test is very rigorous, and if you have a five o’clock shadow, you will fail. It doesn’t matter if you can pass the hand over the intake suction test, the NIOSH leak detector is more sensitive.
The point is, if you have a beard, or a heavy afternoon growth, you are not protected by an air purifying respirator. What you need is a PAPR, or Powered Air Purifying Respirator, like the Trend Airshield, or the 3M BreathEasy.

Neil took the words out of my mouth. I do the same test fit everytime I put it on to make sure I am sealed. I have this same respirator and have been using it for over 3 years. I can attest to the comfort, I often wear it for hours on end and it fits comfortably underneath a lathe face shield.
WHAT?! YOUR FACE BALD! WHAT HAPPENED TO YOUR SOUL PATCH!
facial hair aside, great video, I definitely have to get that respirator, I have had days where I could feel the sawdust in my lungs! Not a great feeling, and it can’t be healthy.
haha, I shave the other day for the coping video so its just now growing back.
Hi Marc,
I’ve been following you since your first post a couple of years ago and I have to admit that you still surprised me with this one, really great content for the topic.
I do have one question. What is the microns rating for the respirators or are they so fine grained that it does not matter?
Hey Jorge. Most of the particulate filters go down to 0.3 microns. Plenty of filtration for woodworkers.
Marc, another great post. I purchased my first respirator this morning. Just trying to follow your lead in safety. Now, I watched the video tonight and I’ll upgrade my filters ASAP.
Thanks.
I have a question, my initial inclination would be no, but I’m going to ask anyway.
Does the filter have any noticeable resistance to breathing, I was thinking that choking down the space that the air has to penetrate might offer some resistance, I imagine it may become more noticeable as it clogs. I don’t imagine that it would be hard to breath with it on per say, but almost like on a delay if you get what I mean?
I have worn my respirator all day on certain occasions and have never really had any problems. So I don’t notice much breathing resistance. It is there……but very slight.
Hi Marc!
Thanks for this video.
I just would like to share my little experience about the dust masks (the white ones).
A few years ago, I did some work in my house and uses these white dusts masks while cutting red bricks with a grinder.
First I bought “cheap” ones available in big hardware stores.
I noticed that at the end of the day, I had red dust outside but inside the mask too!
I had the opportunity to buy a box of several ones in a professional hardware store.
After a day using them, I had red dust outside, but still pure white inside!
Okay, this does not mean that it filtered all the dangerous fine dust but I can tell, there is dust masks and dust masks.
My 2 cents.
Marc -
Great video on dust masks. Liked it so much, I ordered the exact set-up from amazon yesterday. The adapter cover was hard to find. Hope it all goes together.
Are you saying that if I am only in a dust environment, I can get by with just the mask and the pink pads?
Yes, that’s correct. When you have the pink pads on, you are essentially wearing a very expensive (but very effective) dust mask.
Another great video marc
I have the same respirator Marc does and I won’t sand anything without it. It’s pretty amazing how well it works. It is very comfortable as Marc said. If you wear it long enough though, sometimes it will give you a sore neck just from the little bit of extra weight. I highly advise getting one if you don’t have one already.
Hey Marc,
Another good video with a couple of smiles thrown in. I like that.
After spending 30 years in safety in the mining industry I would say you you did your research and did a nice job on the subject.
Keep ‘um comin’.
Jim
Great video, Marc!
The setup I use is pretty close to yours, so I’m pretty sure I’m OK (cough, cough, wheeze wheeze) but it’s nice to know what other (cough hack gurgle) options are available.
My wife suggests to DEFINITELY lose the ’soul patch(?)’ – your best look is clean shaven. I say, “To thine own self be true, bro!” Pasta Power.
Peace.
haha, the day I become concerned about my “best look” is the day monkeys fly out of my butt.
Thnks Marc,
We bought the 3M solution you mentioned.
With hundreds of masks and thousands of filters and adapters on the market it’s a real time saver to get a simple advise what to buy.
Marc,
One of the best vids yet. Thanks for passing along your knowledge. I did some poking around and I’m interested in your input/confirmation. I’ve not seen you do it but it appears you are wearing your organic vapor cartridges and your P100 particular filters (2091) at the same time? You include the adapter to accomplish this. I just found a cartridge filter that I think combines these 2 without using an adapter. Check out the 3M Cartridge/Filter 60921, Organic Vapor/P100. I think it will do both.

Honestly Keith, I have never seen that setup before so I cant really comment on it. But one concern i have is it doesn’t allow you to use the particulate filters alone.
I agree. I like the idea of using the particulate filters alone too, but I thought this would be a compact and convenient option for those times when you want both. I have both of them on order, so I will test it.
awesome video Marc…I was having a hard time understanding why the P100 wasn’t fitting over the 1st stage, and how that would work with the gaps around the back side…then it hit me (duh)….it all comes through the intake port. I’ve got the 7500, and will pick these up (through your store of course). Thanks for the great video man…
Another question Marc – how do you know when the vapor cartridge needs to be replaced?
Hey Gary. Very good question. Here’s my theory on it. If you can smell the fumes, its definitely time to change cartridges. If you can’t smell anything, they must still be working. Based on that “theory”, the cartridges will last a LONG time. So long, in fact, that I get nervous and start to question my own theory, lol. So just to be safe, I replace mine about every 6 months or so.
Marc,
What is the 3M part # for that adapter / cover to attach the particulate filter to the activated carbon canister? Your Amazon links are broken…
The part is listed as #502. But I am not sure whats going on with the links. They work fine on my end.
Marc,
Discovered your podcasts last weekend, been watching all week to catch up with the crowd, and I made it! Loved the refresher on respitory protection. One note about the activated carbon filters, I have been advised by many safety product suppliers to air tight bag your carbon filters as they will continue to absorb VOC’s from the ambient air reducing service life, if you are cheap like most me, a large zip lock bag to put your mask in is the ultimate cheap!
Seems like there is no one at Amazon selling the adapters that allow putting the particulate filter on the carbon filter. … Bummer.
I hope they will be back soon.
Again, another great video.You already covered when to change the vapor filter, but what about the pink pad?
With all the people who are purchasing the exact mask as you, you could start your own Pink Woodworker Stormtrooper army. We will have to call ourselves the Woodtroopers to avoid copyright laws. We can take over the world, I tell you. One table saw at a time.
Well that also depends on use, but I swap mine out about every 6 months.
A pink stormtrooper army! lol awesome!
