How Does an Oxygen Concentrator Work?

A compressor and a sieve bed filter are the different parts of a portable oxygen concentrator. The compressed air is filtered into the concentrator with the help of a compressor. Thereafter, the compressed air gradually moves to the sieve bed filters. The sieve bed filter removes the nitrogen from the air. A six-sided microscopic cube with holes on each side known as Zeolite is present in the sieve bed and this is what helps to remove the nitrogen from air.
