Don’t forget your eyes. As we know from Drinking Water Treatment, viruses are the smallest infectious materials known to exist. Virus can be present in particles of spittle much smaller than the eye can see. And from Fluid Mechanics, we know that these micro sized particles can remain suspended in the air for hours and be carried extensive distances before colliding with an object. Don’t let that object be your eyes!See how many particles are suspended in the air when you catch a ray of morning sunlight through a window. These particles hang suspended, influenced by any passing air current. They don’t settle because their density, size and weight is small relative to the viscosityof the air in which they float. Micro spittle particles are little different in this regard.
Respirator Rating Letter ClassN - Not oil resistantR - Resistant to oilP - Oil Proof
Respirator Rating Number Class•95 - Removes 95% of all particles that are at least 0.3 microns in diameter•99 - Removes 99% of particles that are at least 0.3 microns in diameter•100 - Removes 99.97% of all particles that are 0.3 microns in diameter or larger. i.e. HEPA Filter (High Efficiency Particulate Air).
N95 MasksMost commonly used for Flu or Influenza prevention, these masks are effective according to the CDC in helping to prevent the spread of Flu, swine flu and avian flu transmission from person to person. N95 masks are designed to fit over the nose and mouth of the wearer, and properly fitted can provide excellent protection
Summary: Cloth Masks are useful and still recommended as they protect from respiratory droplets from the wearer escaping to others, are cheap and widely available; whereas, N95 or equivalent respirators protect both the wearer & others.
