The unprecedented rise in the air pollution levels through recent years requires us to make sustainable decisions and take combative measures to ensure our larger good and that of our future generations. The poor average air quality index of India demands us to take such measures at the micro-level with effective indoor air quality monitoring. So let us understand some of the key concepts associated with air quality.

What Is the Air Quality Index?

The Air Quality Index (or the AQI) is a system used extensively by various government agencies for reporting air quality on a daily basis. It serves as an indicator that allows us to assess the air pollution of a specific place at any given point in time.

Usually used to warn the public when air pollution levels are too high, the AQI transforms complex air quality data from different sources into a single number (index value), nomenclature, and color. The AQI is divided into six categories and runs from 0 to 500. The higher the index value, the greater are the levels of air pollution and the associated health concerns.

Air Quality Index in India 

The overall air quality index of India and that of most of its major metropolitan cities is extremely poor. The National Air Quality Index (or the NAQI) was launched by The Ministry of Environment, Forests and Climate Change, on 17 September 2014, with its primary mission to introduce a “culture of cleanliness” throughout India, especially in the urban areas.

The NAQI classifies air quality into six broad categories (Good, Satisfactory, Moderately Polluted, Poor, Very Poor, and Severe) based on the level of severity and the associated health risks. According to the index, some of the most polluted cities in India include Delhi, Noida, Kanpur, Mumbai, Kolkata, amongst others.

What Is Air Quality Monitoring? 

Air quality monitoring is a process involving the systematic assessment of the existing quality of air by measuring the quantity and types of certain pollutants in the surroundings. Some of the major air pollutants include carbon monoxide, nitrogen oxide, sulfur dioxide, ozone, formaldehyde, particulate matter, amongst many others.

An indoor air quality monitor is a device that helps in assessing and interpreting air pollution levels at the individual level with relation to the ambient air quality standards.

Indoor Air Quality Monitoring: Some Major Benefits 

  • Proper indoor monitoring helps the residents to recognize the level and nature of pollution and enables them to identify the source and take corrective measures.
  • The data thus collected enables us to determine if an area is meeting the air quality standards set by agencies like the WHO, CPCB, OSHA, amongst others.
  • Poor indoor air quality in offices can often lead to irritability and diminished productivity. Effective monitoring can help ensure that the workers can enjoy a healthier workplace environment with increased productivity and efficiency.

Wrapping Up 

Indoor air quality monitoring is the first line of defense to combat the ill effects of air pollution. Thus, investing in a good indoor air quality monitor is never a bad investment as it enables you to identify, assess, and eliminate the potential air pollutant sources to ensure your well-being and those dear to you.
