Air cleaning technologies for VOCs are not well established. One of them is (UVPCO) ultra-violet photocatalytic oxidation technology , practically studied only in laboratory settings, where relatively high concentrations of only few VOCs were employed.
This paper reports an experimental evaluation of the performance of UVPCO devices under real or simulated-real indoor conditions where many VOCs are present at low concentrations.
But some issues remain to be investigated, for example, the impact of UVPCO operation on formaldehyde and acetaldehyde concentrations should be better quantified.
