5.1 Monitored Parameters and Health Risks

Image: Detailed table outlining various air quality parameters, their health risks, and corresponding good, OK, and poor ranges.
- CO2 (Carbon Dioxide): High levels can lead to drowsiness and reduced cognitive function. Readings above 2,000 ppm may cause dizziness or even suffocation.
- PM2.5/PM1.0/PM10: Fine particulate matter that can penetrate deep into the lungs, contributing to respiratory issues, heart attacks, and strokes.
- HCHO (Formaldehyde): A pungent, colorless gas linked to serious health issues, including leukemia. Common sources include new furniture and household products.
- TVOC (Total Volatile Organic Compounds): Organic chemicals that can irritate the nose, throat, and eyes. High levels can affect organs and the nervous system. Sources include cooking, paints, and cleaning products.
- Temperature & Humidity: Essential for comfort and preventing mold growth.
- AQI (Air Quality Index): An overall indicator of air quality, color-coded for easy interpretation.
