Greggy..Strongly suggested is what I got from the current mask recomendations.. Electric power has been off here most of the day so I haven't caught up with news things yet.
The everyday use masks they are talking about generally won't filter out a virus particle, but will retain the much larger moisture particles we cough, sneeze and even expel in our everyday breathing and pronouncements of words with certain letter letters in them."k' and 'p' for instance. We've all seen how much moisture we expel in our breath just by observing our breath on a cold day. That's what wearing even a cloth mask is meant to curtail. One in 4 people that are infected show no symptoms and may not their entire infection period, but they are shedding virus particles none the less...infecting others.
Virus particles are very small and light. There is now some research that says the moisture droplets we expel are so light they stay suspended in air and can be carried into ventilation systems. The masks again, keep those droplets inside the masks.
how small?
