ABSTRACT OF THE DISCLOSURE A simplified low-cost system designed for home use in the direct administration of high purity oxygen to a patient, utilizes a single adsorption column containing successive layers of adsorbent. The first layer is composed of a molecular sieve adsorbent for removal of water and CO2 from the air feed stream. The second layer is a molecular sieve adsorbent which preferentially retains nitrogen. The sequence and conditions of the several steps of the operating cycle are designed to recover a therapeutic gas stream of about 90% oxygen content.
