This invention provides systems and methods of supplying oxygen-enriched
air to an enclosed space or compartment. The systems and methods may
distill oxygen from ambient air by a molecular sieve pressure cycle
mechanism, such as a pressure swing absorption, may generate oxygen from
water using electricity or may use oxygen enriched air produced by
membrane filtration. The invention helps people improve their wellness,
productivity and comfort, improve performance of mental and/or physical
tasks, increase their alertness, quality of life and pleasure, reduce
their drowsiness, and aid in curing and preventing disease by increasing
the percentage of oxygen in the enclosed space to a beneficial and safe
level.
