Indoor Air Quality Testing: Why It Matters and How to Get It Right
In today’s fast-paced world, most people spend nearly 90% of their time indoors, whether at home, in the office, or in other indoor environments. Despite this, indoor air often receives less attention than outdoor pollution, even though it can be significantly more harmful.
Indoor air quality testing plays a critical role in identifying and mitigating indoor pollutants that can have long-term impacts on health, comfort, and productivity. With the increasing incidence of respiratory conditions and heightened awareness about wellness, more homeowners, businesses, and institutions are prioritizing indoor air testing.
This comprehensive blog explains the importance of checking air quality, the types of pollutants involved, testing methods, interpretation of results, and how organizations and labs can support this essential need.
What Is Indoor Air Quality?
Indoor Air Quality (IAQ) refers to the quality of air within buildings and structures... health, comfort, and productivity.
Why Indoor Air Quality Testing is Essential?
- Early Detection of Health Hazards – Indoor air quality testing detects harmful elements before they cause irreversible health damage.
- Compliance with Safety Standards – Ensures adherence to guidelines by CPCB, BIS, WHO, and ASHRAE.
- Preventive Maintenance – Identifies pollutants early to reduce remediation costs.
- Improved Indoor Productivity – Positively impacts concentration and reduces absenteeism.
Primary Sources of Indoor Air Pollution
- Combustion activities: gas stoves, tobacco smoke
- Building materials and furnishings
- Poor ventilation
- Biological agents
- Cleaning and cosmetic products
Types of Indoor Air Quality Tests
- VOC Testing
- Mold Testing
- Particulate Matter (PM2.5 and PM10) Testing
- Radon and Carbon Monoxide Testing
- Humidity and Temperature Control

How to Prepare for an Indoor Air Quality Test?
- Avoid cleaning or ventilating excessively before the test
- Note odors, symptoms, or mold growth
- Identify problem zones
- Ensure HVAC access
Interpreting Indoor Air Quality Test Results
| Parameter | Safe Range | Action If Unsafe |
|---|---|---|
| CO2 | <1000 ppm | Improve ventilation |
| VOCs | < 0.5 mg/m³ | Reduce the source and ventilate |
| PM2.5 | < 35 µg/m³ | Use HEPA filters |
| Humidity | 30-50% | Adjust the humidifier/dehumidifier |
| Radon | <4pCi/L | Install a radon mitigation system |
| Formaldehyde | < 0.1 ppm | Replace emitting materials |
Improving Indoor Air Quality
- Install air purifiers with HEPA and activated carbon filters
- Increase natural ventilation
- Clean and replace HVAC filters
- Use non-toxic, low-VOC products
- Control humidity
- Maintain and remediate mold-prone areas
Indoor Air Quality in India: A Worsening Scenario
Cities like Delhi, Mumbai, and Bengaluru show high PM2.5 and VOC levels... testing to mitigate risks and improve well-being.
Frequency of Air Quality Testing
| Parameter | Safe Range |
|---|---|
| Homes | Once a year or after renovation |
| Offices | Every 6 - 12 months |
| Hospitals | Bi-annually or quarterly |
| Educational Institutions | Every academic term |
| Industrial/Manufacturing | Quarterly or as per CPCB norms |
