Back to masks... I received my Marquette masks for my 'donation' yesterday.They're kind of crummy. Oh well.
Georgia governor bans cities from ordering people to wear face maskshttps://www.cbsnews.com/news/georgia-governor-brian-kemp-bans-city-face-mask-orders-coronavirus-pandemic/Georgia's Governor Brian Kemp is explicitly banning Georgia's cities and counties from ordering people to wear masks in public places. He voided orders on Wednesday that at least 15 local governments across the state had adopted even though Kemp had earlier said cities and counties had no power to order masks during the coronavirus pandemic.Kemp's new order also bans local governments from requiring masks on public property, which void requirements that some governments have imposed for citizens to wear masks inside city and county buildings.Moron.

Hm, looking for opinions here...lately folks have been latching onto the idea that masks with ventilators are bad (including my workplace). Here's an example:https://healthnewshub.org/health-news-hub/top-news/do-not-use-a-mask-with-a-filtered-valve-it-can-spread-covid-19/Now, I understand that the ventilator allows "unfiltered" air out, and that *could* be bad. But a cloth mask also allows a lot of unfiltered air out - and that's why they're more comfortable. But - this should only matter if the virus is airborne - correct? Both the cloth mask, and ventilated 95 stop a majority of "droplets" which is their purpose. I mentioned in another thread, I have a couple ventilated N95's, and I'm not trying to be a jerk by wearing them. Am I being jerk? I feel like this guidance is going overboard, and the only risk of using a ventilated mask (or cloth mask) is in "sterile" environments.
valve or vents are bad. It isn't overboard. Analogous to having your fly open and your dick out and still saying you're wearing pants.
Okay help me out here please - does cotton1,2 etc refer to layers? If so, why does it look like cotton3 is worse than the others? Or does it refer to something else? It looks like cotton/poly blends are the best, aside from surgical and N95’s?
There’s a reason I didn’t go into a scientific career 😁.... I was out walking with friends last week and one had a mask with a valve. I kept meandering around trying to avoid it lol.
Sorry I thought that was the full Duke study. Here is the link with the descriptions on page 8https://advances.sciencemag.org/content/advances/early/2020/08/07/sciadv.abd3083.full.pdf
Based on those graphs, any mask is better than NONE and some are a little better than others.
Some masks are an order of magnitude better than others.They really should have made all of those charts on the same x-axis scale. It take time to compare them to each other because each chart's scale is different.
Nice to see some actual data. I had been wearing an unfitted, vented N95 mask (used once, from an old woodworking project) until a week or two ago, when I read reports that I was protecting myself but potentially infecting others. I then switched to my pleated cotton mask to protect others from spread. Guess I will be switching back to my vented N95.

Here someone did this with the pictures. I don’t know if they did it right/accurately https://twitter.com/alirendara/status/1292524052125495297?s=21
