Air Pollution Index Calculator – Know Your Air Quality Instantly

What Is the Air Pollution Index?

The Air Pollution Index (API) or Air Quality Index (AQI) is a system used to assess the level of air pollution in a specific location. It provides a single number or value that reflects the overall quality of air and its potential impact on health.

The AQI is calculated based on multiple pollutants, most commonly:

• PM2.5 (fine particles)

• PM10 (coarse particles)

• NO₂ (Nitrogen Dioxide)

• SO₂ (Sulfur Dioxide)

• O₃ (Ozone)

• CO (Carbon Monoxide)

These values are converted into a standardized index, which helps the public easily understand the air quality condition using color-coded levels (from Good to Hazardous).

What Is an Air Pollution Index Calculator?

Our Air Pollution Index Calculator is a free, easy-to-use online tool that lets you:

• Enter pollution data (e.g., PM2.5, PM10 levels)

• Calculate the AQI based on standard formulas

• See the health risk category

• Get instant results with clear labels and colors

Whether you’re a concerned citizen, a student, or a health-conscious person, this calculator helps you make informed decisions about outdoor activity and health precautions.

How the Calculator Works

The calculator converts pollutant concentrations into individual sub-indexes and then reports the highest sub-index as the overall AQI.

For example, if you enter:

• PM2.5 = 120 µg/m³

• PM10 = 80 µg/m³

The tool evaluates both values using official AQI breakpoints and then displays the higher result as your area’s Air Quality Index.

Supported Pollutants:

• PM2.5: Fine particulate matter (main health risk)

• PM10: Larger particulate matter (dust, pollen)

• NO₂: A common emission from vehicles and industry

• O₃: Ground-level ozone formed by reactions with sunlight

• SO₂: From burning fossil fuels

• CO: Emitted by cars and fires

Why Use an AQI Calculator?

Here’s why this tool is a must-have:

• Plan your day: Avoid outdoor activity when pollution is high

• Protect vulnerable groups: Children, the elderly, and those with asthma need accurate info

• Health awareness: Prevent long-term respiratory or cardiovascular issues

• Environmental education: Great for learning about pollution and air quality science

Example Calculation

Suppose you’re in a city where:

• PM2.5 is 180 µg/m³

• PM10 is 100 µg/m³

The calculator uses the EPA or regional AQI formula to convert these to sub-indices. The result might be:

• PM2.5 Sub-index: 190 (Unhealthy)

• PM10 Sub-index: 80 (Moderate)

Final AQI: 190 (Unhealthy)

This means general public may experience health effects, and sensitive individuals should avoid outdoor exposure.
