Found these masks after looking at a review by a aerosol engineer who recommended them. they are the absolute best for breathability and protection. I work in a school and wear a mask from 7-2 and this is the only one I can wear--plus they look good--lots of compliments. Several of my students contracted covid and even after working closely with them for hours just days before I remained illness free!!!
Easier to breathe then most other masks that have the same protection.
