A simple air filter reduces children’s absenteeism by 12.5%. “It’s a very big effect.”
With the presence of this device, school attendance increased by 1.3 days per student in 5 Milan primary schools, which Reduces absenteeism by 12.5%.
An Italian team installed portable air purifiers high quality in 43 randomly chosen classrooms. Researchers ensure that this device has a more effective effect than HEPA filters.
With the presence a simple AR filterthe team of scientists also found a 32% reduction in particles PM2.5 In these classrooms, although it is not yet possible to see for sure whether the decrease is due to the reduction of air pollution, to lower pollen or pathogenic agents such as viruses.
“It’s a very large effect ”comments expert Stefania Renna, cited by, who presented the results of the study at a meeting of the European Union of Geosciences in Vienna, Austria, this week.
Milan has a particular problem with air quality, because pollution can be retained by the mountains around the city. Although there are other European places where the guidelines of the World Health Organization are not fulfilled regarding the air pollution, “Few other places in Europe are so bad“, Says the researcher.
There are limitations to the study, explain the authors, who do not exclude that there is a psychological contribution to the results. Now other rehearsals are underway elsewhere to confirm. Can the classrooms of the future have to use this basic air purification system?
