Fortunately, airborne bacteria can be effectively reduced through targeted measures:
Practical ventilation: Ventilation remains one of the most effective and simultaneously simplest measures to lower the concentration of germs and pollutants in indoor air. Shock ventilation, where windows are opened wide for a few minutes, ensures a quick and complete air exchange. Cross-ventilation, i.e., opening opposite windows, also creates a draft that directs used air outside. To determine optimal ventilation duration, CO₂ meters are very helpful: if CO₂ levels rise above 800 ppm, that's a clear signal to ventilate. Controlled ventilation not only improves air quality but also increases employee well-being and concentration.
