Concerning masks, I know of no minimum standards for mask efficiency or capacity to filter out germs required to market masks. The governments have mandated that you cover your face. Most "masks" that you see in stores say nothing about safety, but they mention comfort and fit. Few mention ability to filter or limit the spread of germs. And the government sets no standards. Whether it works or not, you must wear one.
These government mandates are about compliance, not safety.
