OT: COVID-19 Face Mask Recommendations

Submitted by seegoblu on July 4th, 2020 at 9:42 AM

I will be returning to work in the next few weeks and would be interested in people’s recommendations for a reusable face mask that is really breathable.

Thus far my public activities have been intentionally limited so I have been using a less than ideal mask (polyester-ish stretchy material). However, given my renewed mass transit commute and  the office setting for my job, I would really love to get something that will both protect me/public as well as not suffocate me in the process.

I have something like this:

https://www.amazon.com/Filters-Reusable-Replacement-Breathable-Pollution/dp/B0868995J6/ref=sr_1_15?crid=1Q1G4R4RY817Z&dchild=1&keywords=95+masks&qid=1593905586&sprefix=95+mas%2Caps%2C165&sr=8-15

 

Ultimately, I don't know how effective it is...the one I have is supposed to be a step below the n95, ASTM level 3, I believe. But it DEFINITELY is more comfortable and cooler than the cloth mask that I have. I also don't have to mess with it because the strap on the back allows me to get a nice tight fit on my face.

I love it.

From now on, Michigan football shall and will only recruit guys named Kyle. 

Any questions?

Under those conditions I'd be wearing an N95, with something else over it.

I scored some 3M 8210's and they're not bad, but I've never worn one for more than a few hours. If it was all day I'd get one with the exhaust valve and cover it with a polyester sleeve.

That's the thing, mask compliance seems to vary widely depending on where you are. Where I live, in Royal Oak, almost everyone is wearing one at the stores (Home Depot being a notable exception). When I went shopping in Canton, it was probably about 2/3.

Somerset mall? Maybe half. But they were all young people.

Hope you and your wife are doing well and successfully dodging the rona.

If you read the study, face shields are very effective at reducing exposure to the virus. They stop droplet transmission and decrease the amount of virus inhaled by the person wearing the shield. They can be an effective alternative to masks for people with glasses and constant fogging and people who are deaf and need lip reading. Additionally, they protect your eyes at the same time.

Igot that, but point still stands.  Face shields are about the person wearing the face shields protection.    Masks are about protecting other people.

From the article 

"It protects you, the wearer," Esper said. "But if you cough, because this face shield is away from your face, those droplets can still get out better than if you have a mask on, where they basically get sucked up by the mask itself."

I think effectiveness need depends on your work situation entirely (will it be on all day, or off/on?etc).  For public transit I’d probably go pretty heavy, and probably wear glasses and maybe gloves just to limit my face/eye touching exposure prior to getting to the office.  That said, the strongest comfort recommendation I can make is get something that ties or connects around the head instead of something with the ear bands.

The keys are to pursue a TIGHT-KNIT fabric and to find one with excellent fit. That will both ensure effective filtering as well as help avoid unfiltered air movement around the mask perimeter. 3 (or 2, but 3>2) layers of cotton is quite fitting in this way.

Beyond that, there are bonuses for materials like polypropylene with electrostatic potential. That boosts filtering to great extent. Such materials are not comfortable on their own, and belong sandwiched between sleeves of cotton. They also can lose their cling in the wash, but can be recharged by an iron or vigorous rubbing.

Otherwise, here are three things to avoid:

 

(1) do not use a mask with a valve on the front. These allow you to exhale unfiltered air around others, thus defeating the primary mask purpose, to protect others

(2) do not wear a face shield alone. This is not a mask. It is a mask augment. Though valuable as a pair, it is close to worthless on its own.

(3) Avoid N95’s in times of rising crisis, or at the very least consult news on the supply chain to ensure you aren’t depleting the market of materials that healthcare providers are seeking as well.

OP, you've got some balls if you're going to be using public transportation.

Of course, details are important. I'm picturing a worst-case scenario (CTA trains in Chicago on Friday evenings after work). Rolling bars, basically, minus bartenders and -- with a few exceptions, anyway -- drinks. Any express bus would be the same or worse. Some regular buses, too. It would be one thing if everyone wore masks. Anyone care to bet on whether the antisocial element will be following those guidelines?
