Thermo King, a brand of Trane Technologies, has released a new air purification system for buses that continuously purifies the air while the bus is in operation and has been independently tested and proven to be 98% effective in deactivating certain viruses.

Thermo King’s air purification solution is integrated into the bus heating, ventilation and air conditioning (HVAC) unit. It uses a filter, paired with special cleaning technology, to capture and deactivate certain viruses, bacteria and volatile organic compounds (VOCs) as the air is exchanged.

It was tested extensively by an independent laboratory following guidelines of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the Centers for Disease Control and Prevention (CDC).

“Public bus transit is a major driver of economic stability in cities across the US, with millions of people who rely on it every day,” said Karin De Bondt, president of Thermo King Americas. “As passengers feel confident about resuming public transport, they will have greater access to jobs and schools, supporting economic mobility across socio-economic groups.”
