If you are going to wear a mask (and you should if you are in close quarters with other people,) please choose one that is likely to protect against viral transmission. The blue “medical style” masks aren’t sufficient. Find N95 or KN95 masks, instead. I like the 3M Aura N95 masks. These and many KN95s are available from Amazon and other retailers.
Want a better mask? There are plenty of options. In fact, the federal agency that I am an advisor to has selected two as winners of its Mask Innovation Challenge. Both the Airgami Origami Mask and Readimask 365 are already available for purchase.
Not sure which masks to get?ProjectN95.org is a reliable website that offers a variety of KN95 and N95 masks and related products.
Which masks do you like? What questions do you have?
I appreciate the mask guide. I've been wondering how much advancement has been made in mask development.
