Development of a new photocatalytic oxidation air filter for aircraft cabin

This paper reports the test results of a new photocatalytic oxidation air filter unit (PCO unit) that has been designed for aircraft cabin applications. The performances of the PCO technique have been measured in a single pass mode test rig to show its ability to decrease the amount of VOCs entering it, and in a multipass mode test rig to measure its ability to clean the air of a room polluted with the same VOCs. The results are promising but the development of that photocatalytic air filter must go on.
