Study: Surgical and Cloth Masks Filter Roughly 10% Efficient at Blocking Aerosols

The commonly worn cloth and surgical masks are roughly 10 percent efficient at blocking exhaled aerosols, a University of Waterloo study found.

The study, examining the effects of masks and ventilation, ultimately found that commonly used cloth and surgical masks do little to filter exhaled aerosols.

β€œThe results show that a standard surgical and three-ply cloth masks, which see current widespread use, filter at apparent efficiencies of only 12.4% and 9.8%, respectively,” the study concluded, noting that KN95 and N95 masks were far more effective at filtering out aerosols.

Personally, I think folks who wear masks have bad teeth or a hair lip. Sorry to anyone whom I have offended.

2 masks = 20% effective, 3 masks, 30% effective, and so on.

Lol....I was just about to post...that these same mask wearers will think effectiveness goes up 10% more, with EACH layer of masks. πŸ˜‚πŸ˜‚πŸ™ƒ

Surgical masks are not made to do what people with they did. Sometime long ago someone posted on this forum that surgical masks are to prevent healthcare workers from breathing into their patients, not to protect the workers.

I was on a flight recently, where the airline demanded masking, and reminded every 5 minutes that passengers must wear masks

There were children playing with their masks or pulling them down. I saw a group of old ladies who pulled down their masks every time they spoke to one another. I saw multiple people who had masks which look like they were made of old t-shirts. There were a few fat people eating the entire flight, so never had their mask above their chin.

The mask requirement was complete nonsense and pure farce

But if it stops \just one\ virus particle that, in turn, saves \just one\ child...

Planned parenthood should refuse both the vaxx and mask mandates.

None of the masks will stop asbestos particles, which are orders of magnitude larger than the Wuhanic Plague virus particles..

Masks DON’T work.

One had to be delusional or a complete moron to think otherwise.

How bout that. I guess eyeglasses constantly fogging up wasn’t a big enough clue.

Yet people who say this about masks dutifully put a mask on when they want to go someplace that "requires" it, instead of saying "NO!"

My first thought about masks being ineffective was smelling a woman’s perfume through one in the grocery store.

Also about masks, people now seem to be handling their possibly contaminated masks like they are just another article of clothing, forgetting that in 2020 it was suggested that we wash our hands often with no concern for drought.

Here's how our "Hollywood certified" masks actually don't work.

Dr uses vape clouds to illustrate how masks do not work (2:55 min.)

Insights welcome.

Our bodies are designed to breath in air with oxygen and breath out C02. Wearing masks restricts O2 and makes the person breath in their own C02 which is waste air.

It is not healthy especially someone with respiratory problems.
