Air Quality Science (Part III): Formaldehyde & TVOCs — The Invisible Indoor Hazards
Formaldehyde (HCHO) and Total Volatile Organic Compounds (TVOCs) are among the most common and harmful indoor air pollutants. This article explains their sources, health impacts, international safety standards, and offers practical solutions for homes, schools, and workplaces. By combining source control, ventilation, and purification, we can significantly reduce exposure and safeguard long-term health. -
Air Quality Insights (Part II): CO₂ and Temperature-Humidity — The Hidden Drivers of Comfort, Health, and Productivity
Indoor air quality goes beyond PM2.5. CO₂ and temperature-humidity balance are critical yet often overlooked. Elevated CO₂ signals poor ventilation, reducing cognitive performance by up to 50%. Meanwhile, temperature and humidity directly affect comfort, immunity, and pollutant behavior. This article reviews scientific findings and provides actionable guidance for homes, offices, and classrooms—helping you maintain CO₂ under 1000 ppm, keep temperature around 22°C, and humidity...
