The E3 study on day cares in Helsinki revealed a notable 18% decrease in children's illnesses after the installation of air purifiers, highlighting the significant impact of indoor air quality on health.
The findings of the E3 study challenge the traditional understanding of virus transmission, suggesting that airborne particles, rather than just droplets or direct contact, play a crucial role in spreading diseases.
Portable air purifiers were strategically deployed during the E3 study at day cares, specifically to double the amount of clean air, providing a direct correlation to reduced illness among the children.
The research involved tracking the health of 51 children over two winters, emphasizing the effectiveness of air purifiers as the sole infection-mitigation strategy in reducing respiratory illnesses in childcare settings.
