6. Understanding Air Quality Readings
The monitor displays various parameters to give you a comprehensive understanding of your indoor air quality:
- CO2 (Carbon Dioxide): High levels can indicate poor ventilation.
- PM2.5, PM1.0, PM10 (Particulate Matter): Microscopic particles that can affect respiratory health. PM2.5 levels can also indicate the presence of mold spores.
- HCHO (Formaldehyde): A common indoor air pollutant from building materials and furniture.
- TVOC (Total Volatile Organic Compounds): A group of chemicals that can be emitted from various household products.
- Temperature & Humidity: Essential for comfort and preventing mold growth.
- AQI (Air Quality Index): An overall indicator of air quality based on the measured pollutants.
