The virus is so small it passes right through all masks except the N95. The N95 is only effective when worn correctly - sealed around the nose and mouth. The other masks will stop virus encapsulated in water but many people wear these masks loosely around their face or leave their nose uncovered thus letting the virus particles out into the environment.
