Masks/respirators for respiratory infections prevention:state of the science review

[saltypits]

So a paper mask with protect you? A cloth mask?

And it's still so sad, when I see people in their early 20s masked up, indoctrination is real.

You only wish they were made of out paper. Those fuking surgical masks are made out of plastic.

[JUSA]

It's true, they're stinking up by the millions in landfills as we speak, which reminds me: Stop eating meat and using gasoline, because *now* we love the environment and landfills full of plastic is okay but NOT eating meat or driving the wrong car.

[HaiMeesk]

Covid is the only health topic you have any knowledge about. The only reason you started this thread.

He's a paid shill...either Big Pharma or Canadia Propaganda Ministry. This has been going on for years.

Well, according to the left, they're not THAT bad for the environment, plus, it's about saving lives......

They are also carcinogenic

[Paul Kreul]

A new study suggests that the excess carbon dioxide breathed in by mask-wearers can have major health consequences.


"While eight times the normal level of carbon dioxide is toxic, research suggests that mask-wearers (specifically those who wear masks for more than 5 minutes at a time) are breathing in 35 to 80 times normal levels.”

[J.L.C.]

You did not refute anything..

Again..Respiratory droplets are smaller than 100nm

What don’t you understand?

You're changing units

What do you think I’m mixing and matching..I presented the facts..the main transmission path is long-residence-time aerosol particles (< 2.5 μm), which are too fine to be blocked, and the minimum-infective dose is smaller than one aerosol particle.
The reason workers in a virus lab wear moon suits, go through multiple sets of sealed doors with decontamination procedures before that suit is removed and breathe pressurized outside air while inside the lab is that these are facts and said virus -- any virus -- will go right through any "mask."

New from 2023?

So masks block CO2 molecules but not viruses?

Just lol

[Paul Kreul]

You're changing units

Because you did.
You claimed..


“N95 masks have a filtration efficiency of at least 95% for NaCl particles 100–300 nm in size."

This is NaCl..respiratory droplets are smaller than 100nm

[J.L.C.]

2.5 um = 2500 nm

[Paul Kreul]

2.5 um = 2500 nm

Correct…respiratory droplets are smaller than 100nm

[J.L.C.]

Correct…respiratory droplets are smaller than 100nm

You said 2.5um

"... the minimum size of a respiratory particle that can contain SARS-CoV-2 is calculated to be approximately 9.3 μm"

Just lol

That doesn’t change the fact that.. respiratory droplets are smaller than 100nm

Just lol

[J.L.C.]

Looks more like 9.5 um (9500 nm)

[Paul Kreul]

I'm discussing virus-containing particles since that's what relevant to the thread.

The study you quoted tested NaCl..not viral load size of respiratory atomized droplets…

Your above quote is incorrect.


“ the minimum size of the respiratory particle that can contain SARS-CoV-2 is approximately 0.4 μm.”

Look at this: https://highlanderjuan.com/wp-conten...-Dont-Work.pdf

Big Pharma freaked out over people finding this and they forced them to do a 180 on this stance because it single-handedly exposed the absolute fraud of their mask agenda. Remember, one of the main reasons they pushed masks so hard was because "masks = the vaccines" - in other words, if you can bombard people with psychological warfare for compliance of masks, that will help Big Pharma to take their bio-weapons, (which allegedly didn't exist yet, but did, and they had to PRETEND they developed "in response" to their scam, to make people clamor for their fake solution) both by direct guilt-tripping, and guilt-tripping from others by weaponizing peer pressure to make them do what the globalists demand.

Since Big Pharma intimidated them, they complied and "updated" their formerly genuinely scientific conclusions in the original document I linked above.

Here's they're backpedaling forced by Big Pharma to make sure people get killed by believing lies:

Update: Why Face Masks Don’t Work: A Revealing Review

If you are looking for “Why Face Masks Don’t Work: A Revealing Review” by John Hardie, BDS, MSc, PhD, FRCDC, it has been removed. The content was published in 2016 and is no longer relevant in our current climate.

Please note that the content from Oral Health Group is primarily intended to educate and inform dental professionals.

If you are looking to further educate yourself on the topic of PPE in the dental industry, we invite you to read the articles below:

Just like how the original definition of "vaccine" was "no longer relevant", and had to be changed to fit their new lying narrative.

Here's a globalist COMPLIANT propaganda piece by the same author from 2023:

Lol

Minimum size of virus-containing particles is what's relevant.

Regardless of this convoluted derail and surprising to few, this study reports masks and respirators work

[Paul Kreul]

Lol

You posted NaCl, not the minimum
Size of virus containing particles that a human breathes out..(which is aerosolized droplets lol)

Confirmed masks do not work

Nope. "... the minimum size of a respiratory particle that can contain SARS-CoV-2 is calculated to be approximately 9.3 μm".

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7579175/

I like how you omitted the conditional "If 1% of the respiratory fluid particle is occupied by SARS-CoV-2,"


There is other work:

"Our data showed that 90% of the exhaled SARS-CoV-2 RNA was found in aerosol particles <4.5 µm"

4500 nm

Size distribution of exhaled aerosol particles containing SARS-CoV-2 RNA

"SARS-CoV-2 RNA was detected in seven of the eight particle size fractions, from 0.34 to >8.1 µm, with the highest concentrations found in 0.94-2.8 µm particles." (940 - 2800 nm)

https://pubmed.ncbi.nlm.nih.gov/36331347/

Nope. "... the minimum size of a respiratory particle that can contain SARS-CoV-2 is calculated to be approximately 9.3 μm".

I presented the other work, all of it showing N95 masks do not stop viral transmission.

It boggles the mind that people are still arguing with J.L.C.

A person known for fudging numbers by two decimal points, omitting key factors, and flat out lying all in support of the narrative he follows.
