First thing I thought of... Stilsuits from Arrakis (Dune) comes to earth.

Wonders if the filters last long (200 gallons or more) or if they're dense enough to filter out acid rain? It's an interesting concept to be sure... a handy piece of survival gear IMO ... provided one is out in the jungles or forests of the Pacific North-West and other places that get a lot of rainfall. If the suit can be packed away small enough to fit in a "day-pack" then it might be a worthwhile investment... please note.. I said "might be".
