This is an actual certified device, not a random piece of cloth that merely resembles a medical face mask “as seen on TV”.

This is way better than the asinine recommendations of public health “officials” to use random bits of cloth.

Would you be willing to stand near a confirmed Covid-19 patient that is only wearing a non-standard, home made, ill fitting, unapproved, face mask made by a complete stranger whose skills you do not know?

That, literally, is what the CDC was directing you to do.
