You need a good quality surgical mask plus a mask fitter like the one made by @FixTheMask.
A disposable face mask made out of meltblown polypropylene layer that passes the candle test is likely good.
Great article by @zeynep and @jeremyphoward. To answer the question they get asked what and "where to buy proper masks," below is a thread. I have no financial interest in these recommendations. My family uses this near N95 solution that costs 17-60 cents/day.
Why aren't we wearing better masks? Last April, we\u201419 experts\u2015wrote paper on why cloth masks were a good stop-gap measure for COVID. It's just been published in PNAS. Great but... @jeremyhoward and I wrote about our frustration that it's still relevant! https://t.co/tsKHCdQlxr pic.twitter.com/3eoia1B3Ue

3. Leakage rates around masks are typically in the range of 20-80% when fit reasonably well to the user’s face, resulting in effective filtration efficiencies that are much lower than the material filtration efficiency.
2/ Key take away @zeynep @ScottGottliebMD @DrTomFrieden @EricTopol @DrEricDing @ASlavitt: we can all upgrade our masks cheaply. Conditional indoor infection probabilities as low as <0.0001 (0.01%) per hour might be reached with the use of surgical masks and mask fitters alone. pic.twitter.com/bWdWeiZNUS

So the cryptocurrency industry has basically two products, one which is relatively benign and doesn't have product market fit, and one which is malignant and does. The industry has a weird superposition of understanding this fact and (strategically?) not understanding it.
The benign product is sovereign programmable money, which is historically a niche interest of folks with a relatively clustered set of beliefs about the state, the literary merit of Snow Crash, and the utility of gold to the modern economy.
This product has narrow appeal and, accordingly, is worth about as much as everything else on a 486 sitting in someone's basement is worth.
The other product is investment scams, which have approximately the best product market fit of anything produced by humans. In no age, in no country, in no city, at no level of sophistication do people consistently say "Actually I would prefer not to get money for nothing."
This product needs the exchanges like they need oxygen, because the value of it is directly tied to having payment rails to move real currency into the ecosystem and some jurisdictional and regulatory legerdemain to stay one step ahead of the banhammer.
If everyone was holding bitcoin on the old x86 in their parents basement, we would be finding a price bottom. The problem is the risk is all pooled at a few brokerages and a network of rotten exchanges with counter party risk that makes AIG circa 2008 look like a good credit.
