1. An isolation system, comprising:
a flexible, portable, disposable membrane with no support structures comprised of a medical grade polymer;
the membrane expands from a contracted state for storage to an expanded state for use;
the membrane in the expanded state has an internal positive pressure, forming a chamber with an opening on one side only;
the opening has a sealing member that when closed, seals off the chamber;
the membrane includes:
an inlet port for ingress of oxygen, compressed air, or air enriched with oxygen into the chamber; and
an outlet port for egress of exhaust gases through a detachably connected exhaust filter assembly, with the outlet port intrinsically functioning as a passive positive pressure regulator.
