Notably, these are researchers from prominent LEFTIST universities finally admitting what we've known all along: masks provide NO protection from an airborne virus like COVID.
Any idiot should know that the shitty little masks are worthless for protecting against illness. Likewise breathing for hours your own carbon dioxide is insane.
I’m with the author.... Where do I submit my application for a letter of apology regarding the attacks and defamatory statements that I’ve been subjected to the past two years? Anyone who has sanded drywall with an N95 knows that it doesn’t stop dust particles that are HUGE in relation to an airborne virus. Notice that in the original Daily News article the message is: “Well yeah...science indicates they don’t work. But, I still wear one anyway.” I also want a get out of jail free pass for punching the next person that says “Follow the Science!”
the % fresh air brought into a building, UV-c and various ionization or other filters cleaners can make a huge difference in viral or bacterial loads and other allergens
Do you know if there are any studies on how effective these things are against coronavirii?
Here's what I'm looking at. The size of a typical coronavirus particle is .3-.4 nanometers. The filter apertures on an N99 mask (better than an N95) are still more than 100x larger than that, meaning that they aren't going to be particularly useful as a mechanical filter. Air filters for commercial buildings don't even approach the effectiveness of an N95 mask as far as I can tell.
The other pertinent issue is that the <20 age group doesn't transmit coronavirus. This has been shown in study after study and was known in Europe even in 2020 before all the lockdowns began. That being the case, I'm trying to figure out if there exists a good case for spending hundreds of thousands - or even millions - of dollars to overhaul air conditioning systems in schools. I'd be interested in hearing your angle on the matter.
Thanks for posting the link, but I found several issues with the article:
1) reliance on "droplet" theory. The problem is that water droplets evaporate in the air, leaving the pathogen to float freely. There was no greater evidence of this than the "seasonal" nature of COVID's effects on the nation with the infection rates mirroring climate conditions - notably humidity. As the weather got warmer and drier, infection rates dramatically increased. The authors failed to address humidity as far as I could tell.
2) reliance on masks. Again, we have data going back 100 years (to the 1918 flu epidemic) which shows masks don't work - with or without ventilation systems. That the scientists were relying on this for part of their analysis shows a lack of scientific rigor.
3) the Six Foot Rule. It was later exposed that the original recommendation from the NIH/CDC was for TEN feet - not six. They settled on six because of the political ramifications but in fact there is zero science even behind that figure. (The actual science I have seen shows that airborne virii can easily travel 60 feet...)
While the formulas are impressive, I also noted that in nearly every section the authors were careful to note caveats and unknowns. I realize that this may not be a precise science but I was very disappointed in the prevalence of such ambiguity.
I do think that UV treatment could be a better possibility. COVID showed a remarkable lack of transmissibility in the outdoors and later studies showed it to be highly susceptible to a variety of cleaners but also UV light.
I reviewed the article again and it has been altered from original, I will look for original. In my office I use the uv'c and ionization air cleaners in each exam room
MIT study that was quickly hidden I think form May 2021 reviewed this in great detail> was done by mathematics professors and physicists on masks air flow ventilation and filtration. Agree with the math on the masks. The study above showed that the best mask might help for about 20min

Look forward to more info on the UV-C, etc.!
