How is the air in the drop down masks on commercial airlines different from the air in the cabin?

1 doctor agrees

In brief: Higher O2

Drop down masks flow oxygen at higher concentration than cabin air. Same principle as when oxygen is given to a patient to breathe.
Higher oxygen concentrations deliver more purified oxygen at higher concentrations than ambient air has, with less impurities also.
