Deb has moved! (see profile) 🇨🇦👀 "While it's somewhat surprising for the widely recommended KN95 mask type to finish last, the team behind the study suggests that the amount of breath allowed to escape around the sides of the mask contributes to the lower score."
Okey-doke. No more of those, then.
I still have some "duckbill" N95s in the cupboard. For when my elastomeric mask is not feasible.

"Of the four types of masks tested, the duckbill N95 mask came out on top: it blocked 99 percent of large particles and 98 percent of small particles from getting out into the air. Overall, 98 percent of the viral load was blocked by the N95. "The research shows that any mask is much better than no mask, and an N95 is significantly better than the other options," says Donald Milton, an environmental health scientist and clinician at the University of Maryland. https://flipboard.com/@sciencealert/sciencealert-3mvdqjtaz/-/a-SNsDdZBoRZCh1aYCEEbt1g%3Aa%3A565656366-%2F0
