Speaking as the creator of a high-quality mask (eye protection, good seal, >99.99% viral filtration efficiency filters), the lack of guidelines on what makes for a good mask have been flabbergasting. And what is there is incredibly lackluster - usually nothing very good on how to check your seal, or about eye protection, or about ensuring your filters are still any good on a disposable mask.
I honestly can't believe that at this point in the pandemic, full-face respirators haven't been adapted to have exhale filters and widely distributed. I think our product (https://narwallmask.com) is still the only such device, and I'm just some software engineer who thought to do something.
