If you have a large enough air supply to maintain a good air flow, the sweat
tends to evaporate... Putting the air supply in the house where the air
conditioner is producing cool dry air helps even more... If you're breathing
cool air, it's not as miserable in a hot poorly vented area...

Not really... If you move your air supply far enough from where you are
working, you're ok... If you can smell the vapors, you haven't issolated the
air supply well enough... With 50 to 100 ft of hose, I can isolate my air
supply and don't need to provide any additional filters...

With a positive pressure air supply system, this is not as important since
the air flow prevent any of the vapors from getting into the mask / hood...
My adapted gas mask also goes over the eyes and the grocery sack derived
hood went over the entire head...

It doesn't need to since the air source is far enough away that I'm not
getting the vapors in my air supply... Basically, if I can smell the vapors,
something is wrong and needs to be corrected...
