Exactly. Two additions: - N95's are used in many other industrial settings - medical is just where they're used to protect against covid. They're terrific masks when used appropriately. - N95's do nothing to protect against getting covid through your eyes, which is a perfectly viable means of contracting SARS-CoV-2, as with any similar virus [1]. This makes the 75x reduction figure seem particularly silly. (disclaimer, I make a mask with integrated eye protection) [1] I cite some studies here: https://narwallmask.com/#h:why-is-eye-protection https://narwallmask.com/#h:why-is-eye-protection
