Development of catalytic filters that deactivate airborne viruses and can be installed in air recirculation or room ventilation systems.
The presence of COVID-19 in aerosol droplets generated by coughing, toilet flushing, etc., persists in the air for long time-periods and is a vector of contagion. Participant groups at the ICP and Hong Kong, which already work together on air quality, currently have a project to develop catalytic filters to eliminate volatile compounds. This technology is transferable to virus removal systems. The HK group carried this out previously for SARS in 2003. Covid-19 has a lipid coating that can be damaged by inactivation. Porous catalysts (discs, wall-flow monoliths) will be manufactured for installation in fan filters and air recirculators. Virus removal is sought at moderate catalyst temperatures (below 70ºC) without effectiveness being compromised by environmental humidity.
