Metrolink Installs Antimicrobial Air Filters Aboard All Trains

LOS ANGELES – As COVID-19 cases across the state soar, Metrolink – Southern California’s regional passenger train service – is again stepping up efforts to keep safe and healthy its riders and employees, the essential workers keeping our communities functioning. Metrolink announced Dec. 22, the addition of new antimicrobial air filters on all its train cars to ensure the air passengers breathe throughout their journey is safe and clean.

In March, Metrolink began implementing a new multi-faceted health and safety program to keep riders and Metrolink employees safe during the COVID-19 pandemic. These efforts include a face-mask requirement at station platforms and aboard trains, enhanced cleaning and sanitizing measures, and partnerships with leading health and safety institutions for guidance on health matters.

The air filters capture airborne microbials and destroy them on contact. The filters screen out 99.99% of the staphylococcus bacteria, 99.91% of the H1N1 virus, 99.96% of E. Coli bacteria and 99.58% of the SARS virus.

The new filters work with Metrolink’s heating, ventilation, and air conditioning or HVAC system, which is itself another protective layer. Intake vents draw in outside air, send it through the HVAC system, then distribute the filtered and cleaned air into the cars. Through this process, the filters screen out and kill not only viral and bacterial particles, but biological and atmosphere odors, providing a more pleasant experience for riders.
