Main indoor air pollutants
Volatile organic compounds
Volatile organic compounds (VOCs) are a large group of chemicals that easily become gases or vapors at room temperature. They are found in many common household products and building materials, and they can have a significant impact on indoor air quality (IAQ).
Particulate matter
Particulate matter (PM) is a mixture of solid particles and liquid droplets suspended in the air. These particles vary in size, composition, and origin, and they can have significant impacts on human health and the environment.
PM is classified by its aerodynamic diameter, which is the size of a unit-density sphere with the same aerodynamic properties as the particle.
PM10:
PM2.5
PM0.1
