I can hear Jony Ive describing it as "fashioned from a single continuous pane of clear polymer" in my ears right now...
Next version will remove the strap and people on HN will complain about how their current bands are useless and they don’t want to change as the older ones are warmer.

Stanford hospital, for example, throws away one N95 per patient doctor visit. They are not sterilizing and reusing. So my friend who works there is using many dozens of them per day. It seems like they could come up with material-preserving procedures like sterilization, but they're not.
Because best data to date is that sterilization procedures damage the mask in ways that render it unsafe. When someone comes up with data finding a safe way to do so, the masks won’t go in the trash. In the meantime, I’d you have the masks to spare, you -should- be using them safely. Masks are pointless if you use them in a way that will get you sick.
There are multiple sterilizing procedures, and multiple material compositions for masks. Which ones were you referring to?
Off-topic, but on the subject of Apple. FaceID is a nightmare to work with, while wearing a mask. The numeric input delay, after trying to open your phone for the 100th time, gets old.
Doesn't the FaceID uses machine learning to "learn" from your face (ie. when having beard)? If not, I'm really disappointed as a vivid iPhone 6s user.

For what, though? And I'm 100% being honest here, what is the specific situation you are envisioning that requires a face shield in your home? In a medical setting, shields are typically used in conjunction with eye goggles and respirators when performing procedures that have a tendency to cause or be around splashing body fluids. Outside of someone sneezing or spitting on you directly, I can't think of an analogous…
You store it in your home, then wear it when you go line up for food in case the person next to you turns and coughs or sneezes.

"Everybody stocking a "handful" of PPE isn't a scalable solution to maintain a national supply." No, but there's no harm in it either, and some potential benefit in case it takes a few days for the federal government to organize a response. We all assume the government is going to make sure the food supply is maintained, but everyone is also buying some extra food just in case there's a temporary gap. We don't need t…
The harm right now is that there's not even enough PPE for hospitals, so anyone buying a face shield for themselves, if that were possible, would keep a face shields from going to a health worker who needs it more. A couple months from now, when pressure on the healthcare system is lower and manufacturing capacity is ramped up? Sure, I'm all for it.
That being said, if I owned a commercial face mask, I would not feel bad. Hording/gouging is not equal to owning your own set of PPE.

It feels as though arguments will be received with claims of "mental gymnastics", so I will just point out the differences in use and function between a face shield and an N95 mask. You're free to try and purchase a face shield if you'd like. Best of luck.
Your question was about the effectiveness of N95 masks. Hopefully I've resolved that for you. As for the effectiveness of face shields, I don't have data on that, I just said it was likely to be effective, since it blocks larger droplets from hitting your face or being inhaled. There's no luck involved, I purchased a face shield almost two months ago, although I usually just wear mask+goggles, gloves if necessary whe…
I also believe you're more naive than I originally thought. I think you need luck now more than ever.
The Czech 3D Printer company Prusa has been on it for a while: https://www.prusa3d.com/covid19/ and they have been open-sourcing the design. You can print it on a 3D printer. Based on that design (and others) makers in Germany have started organizing, so that people can either request shields or supply shields. Organized on Slack and into local distribution hubs. We hace started sharing supplies and even got discount…
What is the point of 3d printing something that clearly needs to be mass-produced in great quantities? Maybe it "feels good", but it's just too slow. I'm honestly not sure why people don't just use plastic food wrap as a cheap improvised alternative for face shields. It's lightweight, readily available, disposable, fits over any attire and does not restrict visibility.
This can be a supplement until the original supply chains are up to speed and the doctor's can get the real equipment through official channels.
