That study you mention was what encouraged me to first get a box of N95s last year! Expensive and wish they were subsidised in Ireland.
RT @mjb302: @NChildersMEP These rapid living reviews written by people who have been shown to be wrong in their droplet theory are not worth spending time on.

They are biased/selective in their choice of studies.

E.g. this is the best study to date in C-19 IMO but it's left out?
