IAQ Monitoring

What is it?

Indoor air quality (IAQ) monitoring is the process of collecting continuous data on particles, gases, and chemicals found in the air. This practice aims to recognize trends, detect issues, and address them by making required adjustments. Consequently, it helps to decrease the risk of airborne disease, discern which factors hamper occupants’ well-being, and identify anomalies.

How does it work?

IAQ monitoring is based on three aspects:

• Hardware like sensors, detectors, and monitors to track air pollutants and parameters.
• The monitoring software system that tracks and analyzes air quality data with time.
• Services, i.e., processes involving data analysis for handling indoor air quality problems.

Methods for indoor air quality monitoring

Typical IAQ methods include the following:

• Continuous/real-time IAQ monitoring, which is about collecting data 24 hours a day, 7 days a week, by employing sensors that track readings provided on a minute-to-minute basis.
• IAQ testing by using a handheld probe to capture a momentary snapshot of air quality.
