Where is this coming from that only a small amount of protection is provided to wearer. For a while I kept on posting studies showing the effectiveness of masks in protection infection by wearer, but it's hopeless - somehow public health authorities have gotten everything so muddled in folks minds.

I clicked the HN link to your comments. I couldn't quickly find studies, just a mention of Korea having success with KN94 masks. I think it's safe to repost them now without being repetitive.
