So, air quality is high priority for employers, building owners to provide safe work environment for employees.

Indoor Air quality can be affected by gases, particulate matters, bacteria, etc and Its quality can be improved by using filters, controlling source, proper ventilation.

Indoor air quality for households can be improved by cleaning carpets, It is also depends on number of members in family, pets, smokers etc.

Determination of Indoor Air Quality involves processes air sampling, testing and analysis of collected sample for various parameters. Major source of indoor air pollution is burning of wood, dung, charcoal for cooking purpose in households.

Indoor Air quality denotes quality of air inside buildings as represented by humidity, temperature, air pollutants conditions which may affect comfort, health and performance of occupiers.

Indoor Air Quality Monitoring & Testing Parameters

In indoor air Quality Measurement process mainly temperature, humidity and airflow (HVAC) are the comfort parameters.

For proper Radon, CO2, Mold, Harmful Chemicals, Dust (Respirable suspended particulate matter RSPM – PM10 and PM2.5), Volatile organic compounds (VOC) and Ozone needs to be monitor. Most of the indoor Environmental quality problems can be resolved by investigating source of CO2 and indoor ventilation without measuring specific parameters.

The indoor air quality monitoring parameters are divided into comfort parameters and contaminants parameters.

Comfort parameters consists of temperature, relative humidity and airflow. These parameters are directly connected to comfort of human being.

Indoor air quality monitoring & Testing also includes measurements of contaminants which are harmful to human being.

Indoor Air Quality Standards (IAQS) India

IAQM Parameters WHO Guidelines ASHRAE OSHA NAAQs/EPA
PM10 50 µg/m3 (24 hr) 15 mg/m3 (total) 150 µg/m3 (24 hr)
PM2.5 25 µg/m3 (24 hr) 5 mg/m3 65 µg/m3 (24 hr)
SO2 20 µg/m3 (24 hr) 5 ppm (8 hr) 140 ppb(24 hr)

75 ppb(1 hr)

NO2 200 µg/m3 (1 hr)

40 µg/m3 (Annual)

5 ppm (8 hr) 53 ppb (annual)

100 ppb (1 hr)

CO 10 ppm (8 hr) 9 ppm (8hr) 50 ppm (8 hr) 9 ppm (8 hr)
CO2 1000 ppm 5000 ppm
Humidity 30% -65%
Temperature 68°F – 74.5°F


73°F – 79F°


Other than above mentioned pollutants it is always recommended to monitor VOCs (Volatile organic compounds), HC (Hydrocarbons), Methane, Formaldehyde, RSPM, O3 (Ozone), Asbestos etc.

However, measurement of other pollutants or contaminants can help to determine the source and target of pollutants which are not causing problems at present but can affect in long run.

Indoor Air Quality Monitoring & Testing Procedure

Before proceeding to Indoor air quality monitoring procedure or method below are the points need to keep in mind:

  • Building type (Residential, commercial and sensitive building)
  • Selection of pollutants which needs to be monitor
  • Diagnosing health related problems due to poor indoor air quality
  • Building ventilation characteristic
  • Number of people
  • Activities in space (burning, smoking etc.)
  • Outdoor pollution
  • Health records or disease history of people

It is also important to know schedule of monitoring, Specifications of monitoring equipments, Selection for sampling points etc.

Indoor Air Quality Testing Locations

The ideal sampling site is depends on purpose of sampling or monitoring. If objective is to monitor indoor environmental quality in offices then location is preferred in office. If monitoring sites are representative of monitoring site then investigator must ensure that site is accurately representative of environmental monitoring site.

More than one point in indoor air quality testing / Inspecting is preferred because air quality is not evenly distributed.

Indoor Air Quality monitoring (IAQM) & Testing

Indoor Air Quality Monitoring Time

Concentration of Contaminants in indoor air are related to humidity, temperature, human activities, therefore selecting time can be very influential in results. It is recommended that two hours indoor air quality monitoring is best practice i.e. One hour in morning and one hour in evening.

24 hours /full day monitoring can be better option when particular contaminants need to monitor.

Indoor Air Quality Monitoring & Testing Duration

The sampling duration of site is depends on the investigation of acute effects of chronic effects on health. Monitoring duration can vary from 15 mins to several days depends on the type of data or sample required. Longer survey can give more accurate and clearer picture of indoor air quality.

Number of Samples in Indoor Air Quality Testing

The number of samples or data points are selected prior to indoor air sampling process based on area and severity of pollutants. Normally in any event at first three samples are taken at monitoring site and If range of these exceeds more than 5% to 15% then additional samples or points can be monitored.

According to EPA (Environmental protection agency) sampling area of 25,000 sq. ft. on continuous floor meets the requirement of one sampling point. It is required to collect air samples for consecutive three days and average the results of each three days cycle for each air sampling zone.

Indoor Air Quality Testing Equipment

The equipment used in indoor air monitoring and testing process must be regularly calibrated as per pollution control boards standards.

Due to increase in time spent indoor, monitoring its quality has become a necessity, in addition It is very important to maintain temperature, humidity, ventilation and draft of a building. Indoor quality monitoring instruments helps to understand their range and based on collected data necessary actions can be taken to avoid health issues.

Indoor air quality testing equipments

Below are some Indoor Air Quality Monitoring devices can be purchased to carry out Indoor air quality testing:
