According to a study, the use of air filter columns at the Stuttgart hotspot Neckartor is having an effect. The accompanying scientific study of the pilot project started at the end of 2018 shows that the pollution of the air with nitrogen dioxide (NO2) and fine dust has been significantly reduced. The Ministry of Transport of Baden-Württemberg announced on Thursday (August 6, 2020).

“The air filter columns in Stuttgart am Neckartor make a significant contribution to the fact that this measuring station is no longer one of the most heavily used measuring stations in Germany,” said Minister Winfried Hermann (Greens). “It is a great success for me.”

The report was published by the Ludwigsburg filter specialist Mann + Hummel, who also set up the 23 pillars. In addition to the state, the city of Stuttgart was also involved in the project. According to the study, an average reduction of 9 percent in pollution was achieved with nitrogen dioxide, and more than 10 percent with fine dust.

The filter columns are only one part of a whole series of measures that are intended to reduce the overall NO2 pollution in Stuttgart below the EU limit value. In addition, there are driving bans for diesel cars, an air-cleaning road surface, and a bus lane has also been set up.

Critics such as Deutsche Umwelthilfe have repeatedly criticized that retrofitting the air does not solve the problems in the long term. For that, the cars would have to become cleaner.
