@MaksiSanctum There was a major paper from 2010 or 2011 that showed mask effectiveness for hospital workers at preventing flu. Those results showed equivalent effectiveness for N95s and surgical masks and concluded imperfect fit was the reason why the "better mask" did not perform better. I suspect the recommendation is based on the data.
@MaksiSanctum The data was fine. Why are you doing this?
@Bertrecords Subsequent studies put that data into question but yeah, when you have an agenda, you grab what data supports your bad conclusions.
