Air Quality Index (AQI) is a globally accepted index that helps people understand how polluted the air is and how it affects their health. The higher the AQI, the more severe the air pollution and associated risks.
Test your knowledge by selecting the most accurate answer:
The Air Quality Index enables smart decision-making-helping individuals, communities, and governments take timely action.
AQI alerts people to limit exposure, especially for children, the elderly, and those with respiratory conditions.
Regulatory bodies rely on AQI to issue advisories, restrict activity, and enforce air quality norms.
Track air pollution trends over time and measure the effectiveness of environmental programs.
The Air Quality Index considers several harmful pollutants. Monitoring them helps quantify environmental risks and health impact.
Fine and coarse particles that penetrate deep into lungs and cause respiratory issues.
Emitted from vehicles and power plants; irritates airways and reduces lung function.
Produced by burning fossil fuels; aggravates asthma and forms acid rain.
A colorless gas from incomplete combustion; reduces oxygen delivery in the body.
Ground-level ozone forms via chemical reactions and worsens lung diseases.
Mainly from agriculture and sewage; causes eye irritation and respiratory damage.
Toxic metal that affects the nervous system and development in children.
Comparing Air Quality Index (AQI) values across countries highlights the global disparities in air pollution exposure and health risks.
Data reflects average AQI values compiled from national and regional monitoring reports.
AQI values are categorized into bands to communicate the severity of air pollution and its impact on human health.
Good
Minimal impact on health
Satisfactory
Minor discomfort to sensitive people
Moderate
Breathing discomfort to people with lung/heart disease
Poor
Breathing discomfort on prolonged exposure
Very Poor
Respiratory illness on prolonged exposure
Severe
Serious health impact even on healthy individuals
AQI is calculated for each pollutant based on its concentration using a standard linear formula. The highest individual sub-index becomes the AQI.
I = [(Ihigh – Ilow) / (Chigh – Clow)] × (C – Clow) + Ilow
Where I is the AQI, C is the concentration of the pollutant, and Ilow/Clow and Ihigh/Chigh are the AQI and concentration breakpoints for that range.
The final AQI value after applying the formula to pollutant concentration.
The actual measured level of a pollutant (e.g., µg/m³ or ppm).
Defined concentration range in which the pollutant value falls.
The AQI scale range (e.g. 51-100) corresponding to Clow and Chigh.
Aurassure offers real-time air quality monitoring solutions using a network of smart sensors, AI analytics, and cloud-based dashboards.
Capture pollutant levels from strategic locations — perimeter, indoor, and stack zones.
Data is processed through predictive models to generate alerts and insights.

Aurassure’s AQI monitoring solutions empower diverse sectors to safeguard health, comply with regulations, and optimize operations.
Monitor urban pollution hotspots, inform planning decisions, and engage citizens with public air quality data displays.
Track emissions from stack, shop floor, and perimeter zones to ensure continuous compliance and worker safety.
Ensure safe air quality for vulnerable patients and staff in ICUs, wards, and operation theatres with real-time alerts.
Protect cognitive development and well-being of students by identifying poor indoor air conditions in classrooms.
Monitor dust and gas emissions during demolition and excavation to reduce violations and local impact.
AQI is a standardized scale that indicates how clean or polluted the air is. It converts complex pollutant data into a single value (0 to 500) and is used to inform people about health risks due to air pollution.
India’s AQI includes PM2.5, PM10, NO₂, SO₂, CO, O₃, NH₃, and Pb. These pollutants are measured and analyzed to generate sub-indices for AQI reporting.
A high AQI value (typically over 200) indicates poor to severe air quality. This may cause serious health problems, especially for people with pre-existing respiratory or cardiac conditions.
AQI is typically updated every minute using live data from monitoring sensors. Aurassure devices transmit air quality data in real time, ensuring timely alerts and accurate reporting.
AQI data is used by government agencies, industries, schools, hospitals, and citizens to make informed decisions. It helps manage health risks, enforce regulations, and shape policies for environmental protection.
Poor AQI can lead to symptoms like coughing, wheezing, headaches, and fatigue. Long-term exposure may aggravate asthma, bronchitis, and cardiovascular diseases. Aurassure’s real-time alerts help mitigate these risks with early warnings.
You can check AQI from government websites or mobile apps, but for hyperlocal monitoring, Aurassure provides IoT-based AQI monitoring devices that give precise data for your exact location.
Each pollutant has a sub-index based on its concentration. The highest sub-index among all pollutants becomes the final AQI score for that hour or location.
Different countries use similar AQI principles, but pollutant selection, breakpoints, and thresholds may vary. Aurassure devices are calibrated to follow India's Pollution Control Board guidelines.
Aurassure offers a full-stack solution for AQI monitoring including advanced sensors, real-time dashboards, custom alerts, and downloadable reports - suitable for cities, industries, schools, healthcare facilities and more.
