Indoor Air Quality Monitoring By Perfect Pollucon Services
Indoor air quality is a growing concern & it directly affects human health. Gases like Carbon Monoxide, Contamination by microbes, Particulate or Volatile compounds diversely affect IAQ. Testing air q…
In India, 80% of people spend their time indoors
So, air quality is a high priority for employers, building owners to provide a 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 also depends on the number of members in family, pets, smokers etc.
Determination of Indoor Air Quality involves processes air sampling, testing and analysis of the collected sample for various parameters. A major source of indoor air pollution is burning of wood, dung, charcoal for cooking purpose in households.
Indoor Air quality denotes the 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 the 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 consist of temperature, relative humidity and airflow. These parameters are directly connected to the comfort of a human being.
Indoor air quality monitoring & Testing also includes measurements of contaminants which are harmful to a 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)

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 | ||

| Temperature | 68°F – 74.5°F
(20-23.6oC)(winter) 73°F – 79F° 22.8-26.1oC)(summer) – |
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 the Indoor air quality monitoring procedure or method below are the points that 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 the schedule of monitoring, Specifications of monitoring equipment, Selection for sampling points etc.

Indoor Air Quality Testing Locations
The ideal sampling site depends on the purpose of sampling or monitoring. If the objective is to monitor indoor environmental quality in offices then location is preferred in office. If monitoring sites are representative of the monitoring site then the investigator must ensure that site is accurately representative of the 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 Time
The concentration of Contaminants in indoor air is related to humidity, temperature, human activities, therefore selecting time can be very influential in results. It is recommended that two hours of indoor air quality monitoring is best practice i.e. One hour in the morning and one hour in the evening.
24 hours /full day monitoring can be a better option when particular contaminants need to monitor.
Indoor Air Quality Monitoring & Testing Duration
The sampling duration of the site depends on the investigation of the 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. The longer survey can give a 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 before the indoor air sampling process based on the area and severity of pollutants. Normally in any event at first three samples are taken at the monitoring site and If the 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 the testing process must be regularly calibrated as per pollution control boards standards.
Due to the increase in time spent indoor, monitoring its quality has become a necessity. Also, 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.
Below are some Indoor Air Quality Monitoring devices can be purchased to carry out Indoor air quality testing:
- LCD Digital Electromagnetic Radiation Detector Sensor EMF Meter Tester: To check electromagnetic radiations
- Forbix Semicon: It can be used to monitor PM2.5 at real-time and average
- HTC 288-CTH Thermo-Hygrometer: It can measure humidity, temperature etc.
- Testo 535 – CO2 meter: This device can be used to Measure real-time & average levels of CO2
- Testo 480: It can measure Airflow, temperature, humidity, pressure, degree of turbulence, heat radiation, CO2, illumination intensity, PMV/PPD and WBGT
- Indoor Air Quality Monitor from Instrumex: this instrument can monitor real-time PM10 & PM2.5, Temperature, humidity, Long battery life.

Frequently Asked Questions
As per CPCB, Good AQI is 0 – 50 falls under Minimal impact. Air quality is considered satisfactory in the range of 51-100 and it can pose little or no risk with minor breathing discomfort to sensitive people. Moderate AQI is 101-200 that can cause breathing discomfort to people with Asthma, Lungs and heart disease. Above Moderate i.e., below AQI 200 Air Quality is acceptable.
If you want to measure air quality at home or office then you need an indoor air quality monitor. These tools will monitor the Concentration of different gases present in the air and provide readings on-screen in real-time. The limitation of handheld devices is they can’t measure more than 3-4 gases in a device. If you want a detailed report and analysis then you can call a professional Environmental monitoring service provider.
Air quality is measured in the Air Quality Index. As per CPCB, if AQI is more than 200 then it can cause breathing discomfort, respiratory illness and it also affects healthy people and seriously impacts those with existing diseases. AQI more than 400 is considered very severe and it can cause permanent damage to human health.
