Making the case for the #CorsiRosenthalBox with studies.
A simple thread.
"no U.S. Energy Star certified air cleaners have CADR values (for either tobacco smoke, dust, or pollen) matching the CADR value for the CR Box even on low speed "
On cost? 1/10th.
1019 to 1444 m3/hr CADR.
(600 to 850 ft3/min)

An incredibly thorough study published in February 2023, with all of its authors from @NIOSH.
With universal masking in a 3-ply cotton mask, exposure to the relevant aerosol size is reduced by 88 to 94%, with the #CorsiRosenthalBox.
73% w/ CRBox alone.

Very good thread on this study here:
Essentially the same NIOSH team investigated HEPA efficacy.
65% reduction with HEPA alone.
So, at a much cheaper price, the #CorsiRosenthalBox gets better results.

But can HEPAs remove SARS-COV-2 from the air? Yes.
(Would #CorsiRosenthalBox do the same? Yes - faster and cheaper.
Has it been studied specifically for this? No. HEPAs barely have.
Do the same laws of physics apply? Yes.)
journals.asm.org/doi/full/10.11…
But can HEPAs really remove SARS-COV-2 from the air?
Yes - in a UK hospital, HEPAs were off. Cov1d was in the air. Turned on. No more CoV1d.
1000 m3/hour CADR.
Remember the first study?
1019 to 1444 m3/ hour for the CR box.

@MarinaC_Dyb and her fellow authors found a massive reduction in aerosols in OCCUPIED classrooms using the #CorsiRosenthalBox. Also found that ALL of the air went in.
No wonder they have rolled them out to 400 locations.

Oh for Pete's sake. @elonmusk has just killed another thread.
Let me add these manually.
"Also found that ALL of the air went in" - quoting above to go into a little more detail:
This answers, in a study, the concern that it just moves the air around. That it won't go into the filter.
It does, and this had to be pointed out.
The CDC, of which NIOSH is part of, has officially recommended 5 ACH, minimum, and that DIY Air Cleaners are effective at reducing the risk of transmission of Cov1d.
The #CorsiRosenthalBox is
specifically mentioned as part of that solution.

@3M has studied it in their formal lab - and is officially on board:
news.3m.com/2022-02-24-3M-…
The famous UL, Inc testing the safety of the #CorsiRosenthalBox, to make sure it won't catch on fire.
It won't - even if the filters are loaded up.

"Does Using Corsi–Rosenthal Boxes to Mitigate COVID-19 Transmission Also Reduce Indoor Air Concentrations of PFAS and Phthalates?"
Yes.

Some have expressed surprise that this was found.
Dr. Corsi explains:
And the rest of your family?
30 case studies- oops, 30 of your stories here, where your family used the #CorsiRi
A thesis - a study, that found 7 PFAs, and exposure to for both dog and human. (@ShellyMBoulder collaborated).
elischolar.library.yale.edu/ysphtdl/2161/
How do we know that dogs are affected? Because it is dogs that get experimented on.
And not to get too personal, but my dog has stage 4 chronic kidney disease. CKD can be caused by PFAs.
Did I do that? Or at least not prevent it? A lot of
wunc.org/health/2021-05…
years with no air filtration.
But hey - she is 15 years old, and it could be just old age.
In any event, I don't want to go into any more detail, but now I know better.
But besides PFAs, dogs can catch Cov1d.
As can cats.
In fact, from the study, we should see our cat as part of our family regarding virus transmission.
Can a cat or dog wear a mask?
Yes, with training.
But what if you could reduce their risk of catching Cov1d without all that?
And the risk to the rest of your family?
30 case studies- oops, 30 of your stories here, where your family used the #CorsiRosenthalBox as the centerpiece of your family pandemic prevention protocol.
And it worked.
