⚠️ 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.


contains the sentence "To learn more about 3M products that use PFAS*, click here."

Great article by @EmilyJoshu here.

Emily, there's another article in this that's even more shocking.

The aerosols from milking have long been discussed by many of us on X.

People like myself, @sri_srikrishna, @AbraarKaran have long advocated for comfortable aerosol
protective gear like PAPRs. But, have been ignored by the USDA who, of course, thought it was only contaminated milking gear like the claw.

But there is one more source of aerosols besides cow breath.

The wastewater. When you spray anything you generate huge amounts of Image
aerosols. And that farm wastewater, filled with milk dumped from being full of H5N1, gets reclaimed and reused.

Those milk and wastewater lagoons are on most dairy farms (my grandfather owned a dairy farm).

And there's something you should know.

Humanity's hubris vs the precautionary principle.

The virus, ANDV, will do what it will do. Pandemic? History tells us "NO." But history is in the past.

Let me show you what the studies tell us - and why I am livid that the WHO is insisting that surgical masks are ok.

🧵
Incubation time, or how long until symptoms show up?

The high risk time frame is 14–32 days. Not to put too fine a point on that, but that can mean a full month later

pmc.ncbi.nlm.nih.gov/articles/PMC32…

There have been some out to 8 weeks, but let's ignore those

gov.uk/guidance/andes… Image
Clinical features The most important complication of ANDV infection is HCPS, which is associated with a high mortality rate. Milder illness without significant cardio-respiratory compromise may also be seen. Illness usually develops 2 to 4 weeks following exposure, but incubation periods as early as 4 days and up to 8 weeks have been described.
But, what receptor does the ANDV attach to?

PCDH1 (protocadherin-1) is primarily expressed in the airway epithelium of the respiratory system, especially in the bronchial and nasal epithelial cells, and in pulmonary endothelial cells.

So, that means in the URT and the LRT.

@mvankerkhove - a follow-up question on today's press conference.

In this bit, you were thanked for being very clear.

But, you said that the medical personnel taking care of those sick would be wearing PPE.

N95s are not PPE. They are Respiratory Protective Equipment. /1
Surgical masks are PPE.

So, is the WHO advising them to wear surgical masks or N95s/FFP2/KF94/KN95 (respirators)?

Second followup, @mvankerkhove, you referred to "really close contacts"

Close contacts are defined by the WHO as within 3 feet.
Cases 1 & 2 were close contacts.

How did the other cases get it? I realize you cannot possibly have an answer...but you are labeling this as "really close contact" for those cases - as well.

Staterooms are typical 2 person rooms.

It doesn't add up. Image

I've become a bit of a Dental Nerd after just getting savaged by avoiding the dentist due to COVID.

But, now, I have a Dental Nasal PAPR, know all about Stephan's Curve, use a waterpik, Oral-B iO Series 10, chew 8 pieces of xylitol gum - and the dentist just said that.....
He has never seen anyone reverse course so perfectly before.

"Immaculate."

And bonus...I ran into a fellow masker in his lobby!!

She had never heard of Readimask, so I was super happy to share the Good Word with her.

Sharing the Good Word - not COVID!
Good point.

Now, this is a very interesting PREPRINT.

We've all heard that shingles vaccination reduces risk of Alzheimer's.

And we all know that Covid increases the risk of Alzheimer's by 50-80%.

What happens when you mix them? Will the vaccination offset a different disease?

/1 Opposing effects of SARS-CoV-2/COVID-19 infection and recombinant zoster vaccination on the risk of late-onset Alzheimer disease View ORCID ProfileCarly M. Rose, Shiying Liu, View ORCID ProfileWilliam S. Bush, Jonathan L. Haines, Scott M. Williams, View ORCID ProfileDana C. Crawford N3C Consortium doi: https://doi.org/10.64898/2026.01.21.26344555 This article is a preprint and has not been peer-reviewed [what does this mean?]. It reports new medical research that has yet to be evaluated and so should not be used to guide clinical practice.
Yes.

But by how much? Conclusions and Relevance SARS-CoV-2/COVID-19 infection and recombinant zoster vaccination are modifiable risk factors for LOAD among older individuals, with a modestly significant interaction between the two. Recombinant zoster vaccination reduced LOAD risk regardless of sex and race, though the protection is greater in those without documented COVID-19 infection. Recombinant zoster vaccination and reduced exposure to COVID-19 infection in the later decades of life reduce the risk of developing Alzheimer disease over at least a five-year period.
Useful for below - "Late-onset Alzheimer disease (LOAD; onset age ≥65)"

"odds of LOAD are 16% higher among those with at least one reported COVID-19 infection" Image

A doctor complaining about wearing N95s? Thread foreshadow in the gif 👇.

Dr. Sax, you should read this.

The arrogance of medical doctors thinking they know better than the CDC NIOSH and OSHA?

This comes as no surprise.
Imagine if an asbestos worker, or a tech working in BioSafety Lab was complaining about this.

But somehow, doctors making over $200,000 get carte blanche and and a piece in the @NEJM Voices.

And he does have a loud voice.
This is Dr. Sax, Clinical Director, Division of Infectious Diseases (ID), at THE Harvard hospital. In 2014, he wrote about how ID docs only make $174,000.

He probably makes northwards of $269,000.

This is very, very relevant.

You see, he is put out by the inconvenience Image
