Secondly, not sure what point you think you're making. Ear loop masks are among the most commonly used masks by your average everyday person during the Covid-19 pandemic, along with home made cloth masks and yes, dust masks. None of which do jack shit to materially inhibit the dissemination or inhalation of SARS-CoV-2 virions.
