Oxygen concentrators work by pulling air in through a filter and compressing it into one of two zeolite towers(molecular sieve). "It is a way to extract oxygen from the air and remove the nitrogen so that the concentration of oxygen is higher than ambient air which is 21%," says Dr. Langdon. "These are safer than traditional pressurized oxygen tanks and more economical and convenient-easier to transport because they aren't as bulky or heavy." 
the air around us is composed of 78% nitrogen, 21% oxygen, and 1% other gases. However, after passing through an oxygen concentrator, which separates and filters out the nitrogen, what comes out is oxygen at a much higher concentration (up to 95%).
