Square graphic with a dark blue/gray background. Top left reads “whn.global”; top right reads “Clean Air.” Large tilted green banner headline: “Ventilation” isn’t just opening a window. Below, a CO₂ monitor screen shows 811 CO2 ppm with status Normal, time 13:54, and POA 84. Other readings on the screen: 36 (Noise, dB), 44.1 (RH, %), 3 (PM2.5, µg/m³), 24.0 (Temp, °C), 3 (PM10, µg/m³), 93 (eTVOC, VOC Index). Bottom text says: “Although that helps, real ventilation is about airflow: how much clean air moves through a space. More clean air means a safer space. CO₂ monitors show if fresh air is flowing — or if it’s time to do more.” Footer: “World Health Network - Science for a safer, healthier world.”
Ventilation plays an important role in preventing airborne infections. Opening a window helps, but real ventilation is about consistent airflow. CO₂ monitors can give a simple signal of how much shared air is building up indoors.
