Mapping the Invisible: Indoor-CO2 Atlas Launches Powerful Global Analytical Tools

In the realm of public health and building science, few metrics are as telling, yet traditionally invisible, as indoor carbon dioxide levels. High CO2 levels inside non-residential buildings like classrooms, cafes, offices, and public transit aren’t just a recipe for drowsiness; they serve as a primary proxy for poor ventilation and an increased risk of airborne pathogen transmission. For years, the…

The Two Lenses of Air Quality: Monitoring & Epidemiology

Understanding indoor air quality (IAQ) is not as simple as glancing at a single number. There is a fundamental complexity in how we interpret air quality data, often leading to a significant gap between epidemiological perspectives, which are health-based limits, and monitoring perspectives, which focus on real-time action at least for GO AQS. We believe that bridging this gap is essential for creating truly healthy indoor environments.

Why South Korea’s New Air Quality Standards Miss the Mark on Ultrafine Particles Indoors

South Korea recently made headlines by tightening its indoor air quality standards. Under the revised Enforcement Rule of the Indoor Air Quality Control Act, the maximum allowable level of ultrafine dust in public facilities—including libraries, museums, and private academies—was lowered from 50 micrograms per cubic meter (μg/m3) to 40 μg/m3. While the Ministry of Government Legislation frames this as a win for public health, particularly for children and teenagers, a growing body of scientific evidence suggests that this "strengthening" of the law is fundamentally flawed.
