Why Ventilation Must Not Be an Afterthought for Healthy Air in Classrooms
Why Ventilation Must Not Be an Afterthought for Healthy Air in Classrooms
Children spend up to 30 hours a week in classrooms—a space that deeply impacts their health and academic performance. Recent research in Switzerland shows that proper ventilation is essential for a healthy learning environment. The findings emphasize the importance of continuous, mechanical ventilation like that from AerosFair to reduce harmful substances and maintain indoor climate control.
Poor Air Quality, Major Consequences
The study examined 24 primary schools, some equipped with mechanical ventilation and others relying solely on natural ventilation through windows. The measurements revealed:
- CO₂ concentrations were on average 20–30% lower in classrooms with mechanical ventilation.
- Volatile Organic Compounds (VOCs), such as formaldehyde and ethanol—often originating from cleaning products and furniture—were also significantly lower in ventilated spaces.
- Particulate matter (PM2.5) was better regulated in buildings with active ventilation.
These substances are far from harmless. High CO₂ levels can lead to reduced concentration and fatigue. VOCs are linked to respiratory issues and irritation. Fine particles have proven adverse effects on lungs and the immune system, especially in children.
Seasonal Influences and Human Behavior
A striking finding was that natural ventilation often falls short in winter. Due to cold or energy-saving measures, windows remained closed, leading to rising CO₂ levels and worsening air quality. Even behavior changes, such as opening windows more frequently, were temporarily influenced by awareness campaigns but did not provide a structural solution.
Continuity Is Crucial
What this study clearly shows: good ventilation requires continuity, independent of season or human behavior. Mechanical systems ensure consistent air renewal, even when it's freezing outside or when attention to air quality fades. This gives schools peace of mind and reliability.
AerosFair Responds to This Need
At AerosFair, we develop ventilation systems that operate autonomously, silently, and energy-efficiently—even when the room is empty. Our technology detects presence, adapts to seasonal changes, and ensures healthy air quality without relying on manual intervention.
Conclusion
Good air quality is not a luxury but a requirement for health and learning performance. Mechanical ventilation makes a tangible difference, and with solutions like those from AerosFair, schools are choosing not just technology, but care, continuity, and future-oriented health.
