Well, exactly. Even the blue ones that come in the box that say they don't prevent covid or other viruses and are routinely worn in medical settings. Nor the fabric ones so many people have bought or made for themselves. It's all so ridiculous. Covid particles are between 1 and 4 microns in size and neither of those types of masks filters out anything below 100 microns. Insanity.
It’s not like anybody is selling medical grade masks.
