How Do Oxygen Concentrators Work? How Do Oxygen Concentrators Work? An oxygen concentrator, or an O2 concentrator, sometimes referred to as an oxygen machine or oxygen generator, takes in the ambient air that we breathe and removes or scrubs out the nitrogen, leaving the other gases found in the air, most of which is highly concentrated oxygen.
Check the air inlet filter to make sure it is in place and clean before you plug in the unit. Wash it in soap and water if it is dirty. Then rinse it, pat it dry, and put it back on the machine. Check the alert buzzer if your oxygen concentrator has one. Push the power switch and the buzzer should sound.
