I never thought face masks were all that effective. The pathogens may be small enough to pass through them and they
do nothing to prevent entry through the eyes which is very
common. A full-face respirator with a sophisticated multi-stage filtration most likely is effective but
they're not very comfortable and the filtration canisters are
often large and heavy enough that they can't be part of the
mask itself, but have to be worn on a belt or shoulder strap and connected to the mask with a hose. Most people probably
would rather take their chances rather than wearing an uncomfortable and encumbering piece of equipment, not to mention the expense of a good respirator system.
