Legally you have to use ABO (Aviator's Breathing Oxygen). The only
difference is supposed the quality assurance for contaminants such as

all to better than ABO standards. He ships bottles marked ABO to
those who require it. Check with some of your local suppliers and
they'll certainly be cheaper than any FBO.
