Two types of oxygen concentrators

How does An Oxygen Concentrator work?
The oxygen concentrator draws in the conventional air in the room and compresses it with a filter and a sieve bed to filter out other gases (including nitrogen) present, and then outputs a high concentration of oxygen. Therefore, the oxygen generator can produce oxygen and no oxygen tank is needed.
