Abstract

According to World Health Organization, urban populations spend 90 % of their time in indoor environments.
Accentuated by the recent COVID-19 pandemic, this raises important concerns about the quality of the indoor
air, which often contains various types of contaminants within three main categories: biological, volatile organic
compounds, and particulate matter. Several technologies already exist for removing contaminants from indoor
air, such as electrostatic based methods or filtration. Although these technologies are well established, they often
target only one or two groups of contaminants. This review focuses on a promising technology: nonthermal
plasma combined with catalysts. After an overview of indoor air contaminants, their sources, and the typical
methods used for their removal, a highlight is put on the available commercial indoor air purification devices.
The latter are rarely described in literature, and the comparison with lab-scale experiments are difficult due to
the lack of information and available data from the manufacturers. The limitations of those systems are also
discussed. As most of these commercial devices use combinations of various conventional technologies, the last
part focuses on the ongoing research on plasma-catalytic systems. The main mechanisms are presented along
with recent literature. Finally, some perspectives for its future development are proposed.
