This article focuses on technologies to purify the cabin air supply on commercial and military aircraft. It provides an overview of typical aircraft cabin air systems, followed by a review of the technologies currently available for aircraft cabin air treatment: disposable carbon adsorbent filters, catalytic converters and nonthermal plasma oxidation. It explains the basic principles of each existing technology and the advantages and disadvantages of each. Finally, it introduces the Pall photocatalytic regenerated adsorber (PCRA) system, which uses a unique combination of adsorbent and catalyst technologies to remove particulate and gaseous contamination from the cabin air supply.
