What is an Air Quality Monitor?

An air quality monitor, also known as an indoor air quality (IAQ) monitor, is a device used to measure and monitor various parameters that affect the quality of the air inside a building or confined space.

Room and window

These devices provide real-time or periodic measurements of specific pollutants, gases, particulate matter, and environmental conditions to help individuals assess and maintain a healthier indoor environment.

Air quality monitors can measure a range of parameters, including:

  1. Particulate Matter (PM): Airborne particles of different sizes, such as PM2.5 (fine particles) and PM10 (coarse particles), which can originate from sources like dust, smoke, pollen, and vehicle emissions.
  2. Volatile Organic Compounds (VOCs): Organic chemicals released from various sources such as cleaning products, paints, adhesives, furniture, and building materials. VOCs can have short-term and long-term health effects.
  3. Carbon Dioxide (CO2): A colorless, odorless gas produced by human respiration and combustion processes. Elevated CO2 levels can indicate poor ventilation and may cause drowsiness, headaches, and reduced cognitive function.
  4. Temperature and Humidity: Indoor temperature and humidity levels, which can affect comfort, mold growth, and the spread of airborne contaminants.
  5. Formaldehyde: A common indoor pollutant emitted by certain building materials, furniture, and household products. Prolonged exposure to formaldehyde can cause respiratory issues and irritation.
