Look at your deodorant while putting it on your armpit tomorrow morning.

Look at your ozone-producing ionizing air cleaner and photocopier when you go into the office.

They combine to produce
Ultra Fine Particles that you inhale, and then they migrate to every organ.

🧵 Perfume spray.
Man spraying on deodorant.
Right off the bat? The non-ozone producing #corsirosenthalbox, does remove UFPs AND volatile organic compounds (VOCs).

So should any HEPA.

BUT.

You will inhale them because your body has a thermal plume from your body.

Sorry for the long setup. You need to read this,
but I did not want to be click-baity.

So, deodorant, hand lotion, body spray, perfume, spray shampoo - and most likely anything that has a fragrance produces VOCs.

"Monoterpenes, in particular, are known to react with ozone inside, forming secondary organic aerosols (SOAs)." Personal hygiene products, including roll-on deodorant, hand lotion, body spray, perfume and spray shampoo, contain an amalgamation of over 200 volatile organic compounds (VOCs), which then react with ozone in the air to form other potentially dangerous chemicals, according to a new paper in the journal Environmental Science & Technology Letters.
Personal care products contain a large cocktail of VOCs, including monoterpenes, acetaldehyde, siloxanes, alcohols, and alkanes. perfume spraying Stock image of a person spraying perfume. Personal care products like perfume, hair spray and hand lotion can release volatile chemicals that may react with ozone to other compounds.
Your fragrant ________ (insert Old Spice, Axe Body Spray, No. 5 Chanel, etc,), produces VOCs. They hit ozone and react. Turn into aerosols.

That clump up into UFPs. And your thermal body plume carries up for you to breathe them in.

Size illustration below. When using the PCPs in the presence of indoor ozone, these reactive VOCs underwent oxidation reactions to form a variety of gas-phase oxidized vapors and led to rapid new particle formation (NPF) events with particle growth rates up to ten times higher than outdoor atmospheric NPF events," the researchers wrote.
SARSCOV2 virus is 100 nm.
Is it me, Mr. Clean Air, just freaking out?

You judge - here are the scientists.

It IS difficult to hear that.

But it has to hit ozone, right? Where does THAT come from? "I know this is difficult to hear, but we're going to have to reduce our reliance on these products, or if possible, replace them with more natural alternatives that contain fragrant compounds with low chemical reactivity," Licina said. "Another helpful measure would be to raise awareness of these issues among medical professionals and staff working with vulnerable groups, such as children and the elderly."
Some definitely comes from outside. But that is short-lived, albeit, if it's always coming in ?

But ionizing air cleaners produce a ton of ozone - whether in-duct or portable air cleaners.

I know there will be a ton of questions. I think
. ncbi.nlm.nih.gov/pmc/articles/P…Highlighting ionizing air cleaners because they produce ozone.
The average outdoor ozone concentration in a day tended to be low in the morning and at night and high at noon. During the year, it tended to be high in spring and summer and low in autumn and winter. The half-life was usually between 7 and 10 min for ozone indoors, which has a relationship with surface removal rate and air exchange rate. Fadeyi [19] proposed that the contribution of ozone air purification equipment with a high ozone emission rate to indoor concentration could easily exceed that of outdoor ozone.
the most common ones will be....

How to tell if my product has monoterpenes? If it has a fragrance, it probably does.

How to tell how much ozone is there?

They sell Ozone Detectors on Amazon.

But, cheap may not be best.

Here's a good article, but

@neiljshaw - — a few tips on your excellent article from a clean air advocate

"Consider Wearing a Mask" ?

No, "It is incredibly important to wear a well-fitting mask such as a N95, KN95, or KF94, for the best protection."

You two are doing Image
public health with this article.

Public health is best done with simple clear instructions.

No:
"These masks act as a barrier, reducing the spread of respiratory droplets when people talk, sneeze or cough."

Yes:
"These masks act as a HEPA air cleaner for the face,
cleaning the air of respiratory aerosols when people breathe, talk, sneeze or cough."

The barrier carries the idea of an immovable wall. Unable to be penetrated by things like oxygen and CO2 - which feeds antimaskers.

As an who debunks antimaskers, it is

As an anonymous clean air advocate, I've put a bit of thought into how to present, well, my expertise.

If someone were to say, "How do I know you know what you are talking about? Are you a doctor, or a virologist?"

To which, I would say...."No, but that's a good thing.
/1
I have focused on aerosol and masking science. Because it is those fields that give us the most information on how airborne particles, aerosols, get from Person A to Person B.

My expertise is derived from the great studies of Dr. Lindsay Marr, MacArthur recipient. Dr. Prather,
double National Academy member, Dr Milton, inventor of the Gesundheit, aerosol scientist and medical doctor; Dr Coleman whose group found that duckbill N95s captured 98% of emitted respiratory aerosols, and more excellent individual aerosol scientists.

I am not a fan of nasal sprays to stop The 'Vid, but I respect you having it as a layer in the Swiss cheese package.

But, some people have said they got bloody noses.

While at the ER yesterday, I picked up a pretty good at home technique. Let our $1,000 lay-out
Image
save you money.

Use tongue depressors to make a nose pinch clamp.

Leave it on for 30 minutes. Still a problem? Two sprays of Afrin, and re-apply nose pinch clamp. Wait 30 minutes.

Still a problem? Cotton balls sprayed with Afrin, clamp, 30 minutes

Afrin- in generic form is $3.32 at Walmart.

Also, put a ice compress at the back of the neck, while doing the above.

"Cooling the nape of the neck is said to induce reflex constriction of the mucosal vessels of the nose"

A study demonstrated 100% PERFECT protection against SARS2 w/ readily available KF94s

✅ 181 HCWs
✅ 1 got SARS2 antibodies, but an epi investigation -> the infection happened elsewhere.
😡 The final checkpoint was March 2021. N95s only became freely available 1 month later
/1 FDA: N95 masks, now plentiful, should no longer be reused By MARTHA MENDOZA and JULIET LINDERMAN (Associated Press) April 23, 2021 12:44 p.m. Medical providers may soon return to using one medical N95 mask per patient, a practice that was suspended during the pandemic due to deadly supply shortages
What is described in the tweets
in the USA.

Korean study:
jkms.org/DOIx.php?id=10…

This is in comparison to a Swiss study during the same rough time-frame. A study which did NOT show the same excellent results, but dismal results. Why?

The Swiss had the same sort of fit testing,

pubmed.ncbi.nlm.nih.gov/35123572/ Results: We enrolled 3259 participants from nine healthcare institutions, whereof 716 (22%) preferentially used FFP2. Among these, 81/716 (11%) reported a SARS-CoV-2-positive swab, compared to 352/2543 (14%) surgical mask users; seroconversion was documented in 85/656 (13%) FFP2 and 426/2255 (19%) surgical mask users. Adjusted for baseline characteristics, COVID-19 exposure, and risk behaviour, FFP2 use was non-significantly associated with decreased risk for SARS-CoV-2-positive swab (adjusted hazard ratio [aHR] 0.8, 95% CI 0.6-1.0) and seroconversion (adjusted odds ratio [aOR] 0.7, 95% CI ...
PPE monitoring.

What was the big difference?

Are N95s/FFP2s inferior to KF94s?

No, it was supply - and other reasons.

@tomhanks has just been savaged by people screaming masks don't work.

All hospitals have fiduciary responsibilities to not waste money.

Here is a light sampling of hospitals mandating masks because they work.

Thread of debunking the myth that "babies should not be masked."

A baby uninfected is better than a baby infected.

If you oppose masking babies, you are immediately for infecting babies.

Let's get to it. A most excellent instruction page on how to mask babies. Suck it antimaskers.
This solves an equity problem.

Not everyone has the money or technical skill to build a baby buggy PAPR.

Just like not everyone has the money to buy an adult PAPR.

Are you for people on SNAP being able to protect their babies? Or not?

Most can rustle up the money to buy some uber cute baby masks!

This is the link from the baby zine.

These need to be fit tested.

Now, let's get into the good stuff. The "OMG Laz has gone too far! We've got him!"

You better bring your A game.
