ALT Can Covid hitch a ride on fog particles that I inhale? Numerous peer-reviewed medical journal reports (linked below) repeatedly establish that Triethylene Glycol (TEG) and Propylene Glycol (PG) have rapid anti-microbial characteristics. Recent studies of one particular formulation confirmed that viruses stronger than Covid can be reduced by 99% in one minute of exposure.  Virus particles are going to be airborne with or without fog. It can be beneficial to allow viral particles join with glycol fog droplets where, according to the peer-reviewed studies, they are quickly inactivated by the glycol. It might be the only thing we have available that can destroy microbes while they float in the air. Also, a common theory holds that as the particles combine and become heavier, they travel less and fall faster.
