With a very tight rig (but not tight-enough) has anyone here tried a filtered positive pressure fan to keep cigar-ash fine dust from passing through window and door seals? It can take hours after journeying to sop up fine dust.
Got the wife on it. But she can't think of the name right now. (retired Hosp facility manger) she had schedule so air (and dust in air) from some patients rooms with weird diseases didn't effect other people.
"Negative air flow" to keep dust(and germs)out or contained to a certain area (or room). Takes elec to power equipment. Wouldn't take to much to make RV air tight. Used to be air planes door were tested to only tested to 12 psi over out side pressure. IE... good duck tape works OK. Not sure how opening RV door problem could be solved. Then again how do you like living in a plastic bag?

You've got us thinking though.
