Carroll County's Knorr Brake Company Develops Air Filtration System to Detect Airborne Viruses

Making public transportation safer amid COVID-19, engineers at Carroll County’s Knorr Brake Company are developing an air filtration system for train cars. The technology installed in HVAC units on metro, rail and light rail trains is capable of eliminating 99.9% of airborne particulates, bacteria, and viruses. “They’re cleaning all the surfaces, they’re spraying everything. But the interesting part is, as soon as one person gets on the train between those cleanings, they could infect the whole train again. So having these technologies applied in the recirculated air brings the greatest safety," said Tyler Bowie, a RailServices sales application engineer.
