As part of the ‘Innovating for the air in our stations’ call for projects issued by the Paris Region, Air Liquide (AL) is testing an innovative air purification solution at the Avenue Foch station on the RER C regional express line in Paris.

All six of the platform air purification units are running since Tuesday, May 28. The experiment will run until the end of August.

At the Avenue Foch station in Paris, AL is testing a pilot project based on positive ionization technology in collaboration with SMEs and startups. For three months, the six purifiers installed will filter 50,000 ㎥ of air per hour to reduce the concentration of PM2.5 and PM10* fine particulates.

To accurately assess the impact of the pilot project, station air quality data will be gathered and analyzed using sensors installed alongside platforms by Air Liquide and SNCF for the period of the experiment.
