Our Urban Air Purifier in the Barcelona Metro

The UAP technical team, together with the TMB authorities and technicians, perform PM1, PM2.5 and PM10 particle measurements together with the CO, NO and NO2 gases.

After the measurement, the results were analyzed at the Polytechnic University of Barcelona (UPC) and it was determined that there were high concentrations of metal particles in the air, which our UAP 2000 fully purifies.
