My company sent me a box of masks and they came with a really cool warning on the side of the box. It says:

This product is an ear loop mask. This product is not a respirator and will not provide any protection against COVID-19(Coronavirus) or other viruses or contaminants.

Wearing an ear loop mask does not reduce the risk of contracting any disease or infection. User is solely responsible for the selection of appropriate personal protective equipment for the setting and application. Change immediately if contaminated.
