What Is an Indoor Air Quality Monitor?
An indoor air quality monitor (IAQ monitor) is a device that measures pollutants inside a building. It helps detect harmful particles or gases that may affect health. Many IAQ monitors also check comfort indicators like humidity and temperature.
Common pollutants an IAQ monitor can detect include:
PM2.5 & PM10 (airborne dust particles)
Carbon dioxide (CO₂)
Volatile Organic Compounds (VOCs)
Formaldehyde (HCHO)
Carbon monoxide (CO)
Humidity levels
Temperature
A good IAQ monitor helps you understand if your indoor environment is healthy or needs improvements.
Why Indoor Air Quality Monitoring Matters
Indoor air can sometimes be more polluted than outdoor air, especially in enclosed, air-conditioned buildings. Poor IAQ can cause symptoms like headaches, eye irritation, allergies, dizziness, and fatigue.
People who are sensitive to indoor pollutants include:
Children
Elderly individuals
Asthma or allergy sufferers
Employees working long hours indoors
Monitoring indoor air gives you better control over your environment, helping you maintain a healthier living or working space.
