Wife and I have separate flights to meetings coming up soon. I'm hoping
both meetings are cancelled. Airports, planes, airport rest
rooms...nothing but bad air and germs.
One of the many reasons I dislike commercial flying. Even in the best
of circumstances with no diseases in abundance, you are still breathing
50% recycled air and 50% fresh air. T
The airlines claim that the HEPA
filters used remove all bacteria and viruses but that's simply not true.
HEPA filters are typically of 0.3 microns, meaning they capture any
airborne particles over 0.3 microns in size. Problem is that
a virus particle is only 0.004 to 0.1 microns in size.
Bacteria particles are bigger, but some can still get through the
filters. They range in size from 0.2 to 10 microns.
Funny thing is ... back when you could smoke on an airplane they used
100% *fresh* air in the cabin. Stale air was exhausted and replaced
with fresh. No filtering involved.
