Learn about key indoor air quality metrics including PM2.5, CO2, VOCs, and how they affect your health and home environment.
Indoor air quality (IAQ) is a critical factor in maintaining a healthy living environment. This post explores the essential metrics tracked by modern air quality monitors and explains how they impact your daily life.
Key IAQ Metrics
Particulate Matter (PM2.5 and PM10) Particulate matter consists of tiny particles suspended in the air. PM2.5 refers to particles smaller than 2.5 micrometers, while PM10 includes particles up to 10 micrometers in size. These particles can penetrate deep into your lungs and even enter your bloodstream, causing respiratory and cardiovascular issues.
Carbon Dioxide (CO2) While not directly harmful at typical indoor levels, elevated CO2 concentrations can indicate poor ventilation and may lead to drowsiness, headaches, and reduced cognitive function.
Volatile Organic Compounds (VOCs) VOCs are gases emitted from various products including paints, cleaning supplies, and building materials. Long-term exposure to certain VOCs may cause irritation, headaches, and even damage to the liver, kidneys, and central nervous system.
Temperature and Humidity These comfort metrics also influence air quality. High humidity can promote mold growth, while low humidity can cause dry skin and respiratory irritation.
Monitoring Your Indoor Air Modern air quality monitors can track these metrics in real-time, providing valuable insights into your home environment. By understanding these measurements, you can take proactive steps to improve your indoor air quality and create a healthier living space.
