Spring is coming: Less Corona, more allergies
Spring is near - and with it an easing of the Corona situation. However, the virus will remain with us for many years to come, according to the experts. What will also stay with us: The important issue of "healthy air in classrooms".
So while less infectious aerosols can be expected in spring and summer, another familiar problem emerges: Airborne allergens in the form of countless flower pollens. According to the German Robert Koch Institute (RKI), one in eleven children under the age of 17 in Germany suffers from hay fever. That's well over 1 million children, most of them of school age - a "stabilization of the frequency of illness at a high level," according to the RKI. "Hay fever" sounds harmless at first, but the children's level of suffering is high: coughing, rhinitis, watery and itchy eyes, and in severe cases, even asthma. For many children, the ability to concentrate at school is affected, and regular lessons are only possible to a limited extent for weeks on end.
Fine dust - The underestimated danger in the classroom
And it's not just infectious aerosols and allergens that pose a health risk in the classroom. Potentially dangerous particulate matter is also repeatedly measured in high concentrations: Quite different residues accumulate in the rooms: Some brought in from the environment, some particles from ceilings, walls and furnishings. Similarly to a strong pollen count: even with a high fine dust load, generous window ventilation can hardly provide a remedy, because often the load outside is at least as high as inside.
Sustainable solution from AiroDoctor: HVAC systems with photocatalysis
The past years have shown clearly: Only sustainable and clever air purification ensures regular and healthy air in schools. Health risks such as infectious aerosols, allergens and fine dust can be minimized easily and quickly with the right technology. Equipping schools with mobile air purifiers was an important first step in this direction, but in some places it was implemented far too hesitantly.
As a result, teacher and parent representatives are now calling for larger air purification solutions to be installed or retrofitted in classrooms. "The issue needs to be thought about on a large scale and in a sustainable way," says Carsten Hermann, CEO of ScreenSource GmbH and co-developer of AiroDoctor® photocatalysis technology. "It's about time to equip HVAC systems in schools with a powerful and hazard-free filter technology."
