Coronavirus vs. the economy, stupid!

Widely used N95 respirators filter out most airborne particles down to 0.3 microns in diameter. The coronavirus is .2 microns in diameter. So the coronavirus is smaller than .3 microns in diameter and can penetrate the N95 respirator filter. There is no 100% guarantee that a mask will capture every virus that lands on your filter. At .1 microns or less it is already very hard if not realistically impossible to breathe normally through a filter.  However, a mask worn by carriers or potential carriers of the coronavirus will substantially reduce the virus particles emanating from their breath, especially when they sneeze or cough, so humans surrounding them are less likely to inhale the virus from the carrier. Since the breath water from the lungs lodges in the face mask, it is a decent trap for small coronavirus particles which wind up mostly lodging in the moist mask.  So carriers, humans venturing into public places, or potential carriers of the virus should definitely...(Read Full Post)
