How does a zeolite oxygen filter operate?

Zeolite acts as a molecular sieve in an oxygen concentrator, playing a crucial role in separating oxygen from other gases in the air. Its unique crystalline structure with micropores selectively adsorbs nitrogen when air is passed through under pressure. This selective adsorption increases the concentration of oxygen in the remaining gas stream. The zeolite’s ability to adsorb and release nitrogen efficiently is the cornerstone of the Pressure Swing Adsorption (PSA) technology commonly used in oxygen concentrators. Without zeolite, the concentrator would not be able to provide a high-purity oxygen supply needed for medical or industrial applications.
