Masks

[Hards Alumni]

Back to masks... I received my Marquette masks for my 'donation' yesterday.

They're kind of crummy.  Oh well.

[4everwarriors]

Probably do two crummy donation, aina?

Agreed. But I'm not disappointed I donated anyway.

Glow and I are in Las Vegas. They are taking masking very seriously. I would say compliance is close to 100%.

No one is allowed to sit at an actual bar. There is only table service. There was one lounge open at the Golden Nugget and we were asked to pull our masks up in between sips of our drink.

Not surprisingly, it is a ghost town.

In Georgia after road tripping through northern Florida. Minimal mask wearing. Those that are usually have them below the nose.
The park ranger at a Fl state park entrance didn’t have a mask. Neither did the very large group of 20 something year olds at the park.
Getting take out, the people preparing the food had their masks under their chin here in Georgia. The person giving us the food was sans mask.
Glad to be in an isolated cabin for the next week.

ETA: Interestingly enough, the place we saw the most mask wearing was the University of Florida.

Fall & winter are gonna be bad

Dr. Murphy on the WGN morning news said that wearing the mask below the nose destroys 80% of its effectiveness.
It is disheartening to read about all the masklessness. I fear we will never get out from under.

Georgia governor bans cities from ordering people to wear face masks
https://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.

I can think of another 'm" word. Redrum! Redrum!

Neck gaiters are actually worse than useless.

Thank you for posting this!  It actually helps answer my "valved 95" question I had asked earlier...

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.

The study linked actually has a nice chart showing total droplet count released (attached).  Turns out, vented 95 is on par with most cotton masks.  Fitted N95 and surgical come out on top, a bunch of others are reasonable (cotton, vented n95, etc) many are worse.

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.

You're wrong (as is related to my vented n95 question).  Unless you also think all those with cotton masks are the same.

Edit: here's the link to the supplementary data:

Edit 2: funny enough, this just showed up in my news feed.  So hard to get accurate information!

Based on those graphs, any mask is better than NONE and some are a little better than others.

[Warriors4ever]

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?

Page 8 in rocky’s link has a more in-depth description, even though it leaves a non mask expert like me with some more questions.

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 8

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.

[Warriors4ever]

I have some masks that don’t seem to fit the pictures. I also can’t figure out why the one-later pleated would perform better than the two-layer, if I read this chart right.
What is an Olson mask?

[Skatastrophy]

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.

Yes, and I even had trouble figuring out whether mask descriptions were on top or bottom of the chart.  Nonetheless, good data.

Agreed on data, BUT I'll caution about using the vented still.  CDC has been issuing guidance to avoid them, so on flights, some restaurants, etc you'll sill be denied entrance.  Keep your neck gator around for those situations!  lol.

I mean, it's a shame official mask guidance hasn't been based on studies, but that's what we get these days.

Why has nobody studied the N100 respirators in these comparisons?
