Improving indoor air quality in learning environments, particularly through filtration, helps optimize students' cognitive abilities and academic performance.

The research community strongly converges on the idea that air purity is a major lever for brain function. Research effectively supports that air pollution, rich in fine particulate matter, is correlated with a decline in cognitive performance and neurodevelopmental risks (observational studies cited by The Guardian/CNN). Furthermore, the presence of mold is documented as an environmental factor that can impair neurological health (review in PMC). However, users rightly point out that filtration alone does not solve everything: carbon dioxide, which accumulates in confined spaces, has a distinct and measured impact on mental clarity and responsiveness (RCT-type studies). The idea that natural ventilation is an effective alternative is scientifically sound for diluting pollutants, although its effectiveness depends on the quality of the outdoor air. In short, while the link between healthy air and cognition is well established, actual efficacy depends as much on filtration as it does on air renewal to manage CO2 levels.
