⚠️ PFAs from 3M ⚠️

🤬N95, N100, PAPR.🤬

Just found this, so giving you a heads up. Source at end.

On a personal note, I know some of you have some of these, and I am both sorry and livid for you.

P100s have PFAs.
( I have a rack of these.)

/1 Image
PAPR - Versaflo, Powerflow. Read for details.

/2 The 3M™ Versaflo™ TR-300+, TR-600, TR-800, and Powerflow™ PAPR motor blowers contain PFAS in certain blower housing components to help manage heat and seal the circuit board, as well as lubricate the motor. This motor blower is sold by itself, as well as in kits where it is paired with multiple breathing tube and headgear options. Some products utilize lithium batteries which may also contain PFAS. The 3M™ Versaflo™ Breathing Tubes BT-20S, BT-20L, BT-30, and BT-40 which are used in certain powered and supplied air system configurations to connect the headgear to the air source, use a...
JFC. 3Ms R, P, and HE filters.

@3M. P100, you greedy jerks?

@NIOSH_TWH @NIOSH - you realize we are going to FOIA you, right? I know you guys read my tweets, so let's get this fixed?

/3 Image
3M’s 7800, 7800B, FF-400, and FF-800.

(I huffed PFAs with P100s, and dodged the bullet on this one so far, as I have the 6800.) In addition, 3M’s 7800, 7800B, FF-400, and FF-800 Full Facepiece Reusable Respirators contain a speaking diaphragm that is used to help provide easy communication for the wearer to those around them. This speaking diaphragm contains PFAS. The FF-400 and FF-800 respirators also have a coating that is applied to the facepieces’ polycarbonate lens to allow for improved paint and stain resistance for easier cleaning. This coating contains PFAS.
@3M - it's the science of poison, not fluorochemistries.

Did you come up with the PR campaign for @DuPont_News's Teflon, the Happy Pan, as well?

Greedy bastards.

Source for all of this. I almost skipped this because I knew the firefighting gear was contaminated. But thought it was a little long for just one product.

multimedia.3m.com/mws/media/2303…
Back in 2021, Sean Lynch of @3M said that surgical respirators did NOT contain PFAs.

Which sounds like a lie as they are EXACTLY what would work good with PFAs to repel blood, etc

But he DID say that some models of their STANDARD N95s may contain some PFAs in the headbands. Image
So, at least the PFAs is not in the filtration? But it is concerning that only 3 years later, their PFA document does not mention N95 headbands.

Did they get rid of the PFAs so quickly? When they are not required to until 2025 (and only piecemeal).

eenews.net/articles/face-…
And, of course, this was in 2021 and 2023, long after 3M supposedly began to phase out PFAs in 2000.

Which was touched on in their testimony declaring minimal health effects.👀

I have been a fan of 3M products, and now am a tad shocked.
pfas.3m.com/3M-to-share-re…
Image
And the trust is gone.

Anyone have the ability to test Filtrete 1900 for PFAs? 👀 Image
Want to help light a fire under 3M?

Hit their chat up on Monday and ask about your favorite 3M respirator to see if it has PFAs in it.

See what doc they provide you. Let's compare notes

And absolutely great point about all of the respirator companies.

Please reply back here what you hear, try to get some sort of formal document.

Also great point.

But my stance is that I want to avoid them as much as possible.

Just like Covid.

There was a study on the #corsirosenthalbox that showed reduction of PFAs through using the box.

Went back and reread it.


The box in question used Jim's TexAir filters.

Here is a link to his filters:
pubs.acs.org/doi/epdf/10.10…
texairfilters.com/filters-for-bo…
Image
Here is the article that covers the PFA study that will be easier to read for most.

To clarify- we don't know if 3M filters, Filtrete 1900, have PFAs or not. But are pushing to get them tested.

I personally have 8 of them where I am living, and I am not
brown.edu/news/2022-12-2…
tossing them until someone does test them.

If I need to replace a set before they are tested or @3M replies? I will be buying Jim's filters based on that study.
And here we go.

@marigoldglitter showing the way by hitting the PPE company annual report.

PFAs in the majority of @DraegerNews products. So, Dragger....got PFAs in your respirators? If so, where?

Thank you @profahnhmc!

I've uploaded a copy to Google sheets. Anyone with this link can open it. NO write access granted.



Let's do an example - Aura. Pay attention, please, as I am not going to look up everyone's respirator.

docs.google.com/spreadsheets/d…
Click on 3 dots (the hamburger).
Click Find and Replace.
Type in aura OR the respirator number. To the right in tiny writing it shows 1/1.
If more then 1/2, click on little arrow to jump to each one.

Sorry, folks, we can see the 9211+ Aura is right there.

Scroll to the right


Image
Image
Image
Image
Columns D- F. Labels below.

Aura, 9211+ has "0.01 - 1%" as the "(#1) % PFAS Range"

F029-Flame retardant is the purpose.

Notice Column D?

That is "Date Product No Longer Contains Interntionally-Added PFAS (Reformulation/Discontinuation)".

The blank line means nothing
Image
Image
scheduled. I am sorry.

Not done yet.

Scroll to the right to column K, and check for another vendor, which is the second vendor involved.

Q is 3rd.
W is 4th.
AC is 5th
AI is 6th
AO is 7th

I presume that if there are multiple vendors, they fill in from the left. Image
Let's check for the Aura 9205.

After clicking on the down button, no 9205 is on this list by either Aura or 9205.

Neither is the 9200, the 8511, the Vflex 9105.

One caveat - it appears that 3M is in the process of discovery. The language used is careful to say they may add


Image
Image
Image
Image
more.

An script could be written to check on the most common respirators and alert if one is added. Just in case someone is feeling frisky.

Went to look for the 6000 series.
Tried 6000. Not clicking 2,070 times.

7000001934 is the MPN. It is NOT ON THE LIST.
Image
Image
So, does this work consistently?

I check the Secure Click FF-802. Yes.

So, if you get too many results look for the "MPN" on web sites. 3M calls it the "SAP Product Code", column B.
Image
Image
So NOT ON THE LIST
6800 elasto,
8511
9200
VFLEX 9105

ON THE LIST
Aura, 9211+

HF-800 secure click not on the list - but many of the filter cartridges are. ("Secure Click").
I WILL NOT BE LOOKING UP ANYBODY'S RESPIRATORS.

Please do not ask me. Please ask each other. Please help each other.

I have not eaten breakfast due to pounding on this, and it is 5 pm.

Waffles for dinner because why not.
@crwequine Just added to the thread how to check the 26K long list of products.
How the heck did @profahnhmc spot this?

Bravo!

(pfas.3m .com/ pfas_uses ) -shove those words together.

Got bored. Let's just check out Google Scholar and E Coli. Oh my. Oh my, that's not good.

Yes, yet another episode of "that's airborne, TOO?!!!!!"

THREAD
Pigs:
"Airborne E. coli were isolated from indoor air,....and downwind air samples (10, 50, 100, 200 and 400 m away) for five swine houses" (1)

Cows:
"E. coli was isolated in both inside and outside air, even in samples taken 150 m from the farm." (2)

READY FOR THE FUN ONES?
Restaurants:
"E coli was identified as the most prevalent illness-causing bacteria in Zone A-derived aerosols (721 CFU)"
(3)
Hospital:
"The results also showed that airborne bacterial pathogens were present in all the sampled hospital wards." (4)

Pope Francis passed - R.I.P.

He died from not masking.

Not masking led him to getting polymicrobial respiratory infection (multiple pathogens) on 2/6/2025, leading to bronchitis, to bilateral pneumonia, a respiratory event
- leading to stroke and cardiac arrest.

Why didn't he mask? The peer pressure must have been enormous. Even those who know better often don't mask out of fear of social castigation.

And that's why mask mandates work so well. They allow people to mask if they want to.

And those who don't want to? Won't. But...

This links to the article from March 27th, 2025, with Trump saying it was so nice of a reporter to be wearing a mask.

There's a video of him on this page.

President Donald Trump stopped answering San Francisco Chronicle Washington correspondent Shira Stein, @shiramstein, to comment on her wearing a COVID mask in the Oval Office, remarking, “You’re wearing a mask! So nice of you!” SHIRA STEIN: Mr. President, you said you want to return education control to the states, how would you handle it if a state like California were to put in place education policies that you don’t agree with? PRESIDENT DONALD TRUMP: You know, I haven’t seen a mask in so long! You’re wearing a mask! So nice of you! I haven’ seen anybody wearing a mask in a long time. It’s good. You feel more comfortable, right? SHIRA STEIN: Yes. PRESIDENT DONALD TRUMP: Good. That’s good. So go ahead. SHIRA STEIN: You said you want to return education control to the states.

Our faces, our health.

And we choose to mask.

Ms. Stein was later singled out by Marjorie Taylor Greene in her for wearing a mask.

Very insulting, at first. But, after Ms. Stein pointed out she was immuncompromised (also having had a stroke, higher risk), she

Trump is trying to distract from the economy. He just pumped out the Lab Leak from the official whitehouse.gov website.

Simultaneously making masking advocacy both more difficult and easier.

The Shrodinger Presidency. If only he had.... /+

Of course I don't wish him dead in a box. That is against Twitter's TOS.

But, anyway, what do I mean? On the one hand, pointing out that Covid is probably a bioweapon means that you can point out the silliness of not protecting yourself against it.

On the other hand, this: Image
Which, of course, is silly as workers in BSL2-4 labs wear N95s and better to protect against bioweapons.

Heh. I can tell an antimasker wrote that because they screwed up the logic on it.

Mask mandates do NOT equate masks.

@TheAtlantic @danengber Heh - I suspect Mr. Engber has been eavesdropping on my (and my fellow Covid Conscious) swimming safer threads. I have a new solution for showering safer for that I will be rolling out tomorrow.

For future articles by those who will come along, let me point out a few things /+
@TheAtlantic @danengber Thank you very much for pointing out that 4% of America is still masking 100% of the time! That is 13.2 million Americans.

The Masking Nation is larger than 38 states. :)

But, 18% of us masking some of the time in the SAME PEW POLL (tch tch). You would think that would be/+ At a basic level, their COVID-conscious attitudes may not be so far from the mainstream. Twenty-one percent of Americans still think of the disease as “a major threat” to public health, according to a recent poll from Pew Research Center. Thirty-nine percent say we’re not “taking it seriously enough.” But if 50 million to 100 million adults harbor such concerns, very few are doing much about them. Masking rates were once as high as 88 percent; now they’re close to nil. For those who still maintain their masking habit—4 percent, says Pew—the whiplash in social norms has been a shock.
@TheAtlantic @danengber be mentioned, @TaylorLorenz, by Mr. Engber, since 18% lines up pretty closely to the 21% still worried that Covid is a big deal (it is) - that he mentioned.

And suddenly, Masking Nation has 59.4 million residents. We are the largest state. Canada /+

This may be one of the most important studies in a decade.

#LongCovidBinder.

"The models produced correctly classified those with severe ME/CFS from recovered controls with an accuracy of 97%, sensitivity of 94%, and specificity of 100%. "

THAT IS HUGE.
"We found that at Stage 1, those fated to develop ME/CFS 6 months following IM had low levels of IL-5 and IL-13 [25]. " We found that at Stage 1, those fated to develop ME/CFS 6 months following IM had low levels of IL-5 and IL-13 [25]. IL-5 enhances the production of B1 cells which are anti-inflammatory (impaired B1 cells have been found in multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis), and IL-13 has anti-inflammatory properties. Jason et al. [26] also found that students who failed to recover from IM had more restricted, inflexible cytokine networks whereas those who recovered had more flexible, less interconnected networks. Network analysis suggests that IL-5 and IL-13 influe...
So, this means ME/CFS can be predicted.

And what can be predicted - treatments can be found.

And they are studying LongCovid as well.

This study is easy to read, And everyone should.
