Hospitals aren't going to sink or swim depending on whether they can save 10-15c per face mask, and being the U.S. they probably charge the patient $10/mask regardless.
But that’s beside the point. Almost all disposable medical supplies are cheap in isolation. They build contracts for a whole bunch of supplies, in massive quantities, over time.
Those pennies add up.
Again, operating margins <2%.
Until you’ve internalized what that means, I don’t see a high value in going back and forth.
