AQI Results
Enter the levels of the main pollutants to get an estimate of the Air Quality Index.
Interpreting the Results
The Air Quality Index (AQI) is divided into several categories, each with a different meaning for health.
| AQI Range | Level of Concern | Health Message |
|---|---|---|
| 0-50 | Good | Air quality is considered satisfactory, and air pollution poses little or no risk. |
| 51-100 | Moderate | Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people. |
| 101-150 | Unhealthy for Sensitive Groups | Members of sensitive groups may experience health effects. The general public is not likely to be affected. |
| 151-200 | Unhealthy | Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects. |
| 201-300 | Very Unhealthy | Health warnings of emergency conditions. The entire population is likely to be affected. |
The Invisible Threat: Air Quality and Health
The air we breathe is a complex mix of gases and microscopic particles. While clean air is essential for life, pollution has become a major global health challenge. The **World Health Organization (WHO)** estimates that air pollution, both indoor and outdoor, causes millions of premature deaths each year. Particulate matter, ozone, sulfur dioxide, and other pollutants can penetrate deep into the lungs and bloodstream, causing a wide range of diseases from asthma and bronchitis to heart attacks and strokes.
The **Air Quality Index (AQI)** is a tool designed to communicate the level of pollution in simple terms. A high AQI value indicates greater pollution and therefore greater health risk. This measurement is crucial for public health, as it allows authorities to issue warnings and people to take preventive measures, such as reducing outdoor physical activity on high-pollution days. In the context of sustainability, monitoring the AQI is a fundamental component of urban planning and environmental policy, as it provides tangible data on the effectiveness of efforts to reduce emissions.
Key Pollutants in the AQI
The AQI is based on the concentration of several key pollutants. The most common are:
- PM2.5 and PM10: Fine particles from vehicle emissions, industry, and combustion.
- Ozone (O₃): A gas formed by a chemical reaction of pollutants from cars and industry in the presence of sunlight.
- Carbon Monoxide (CO): A gas produced by the incomplete combustion of fossil fuels.
- Sulfur Dioxide (SO₂): A gas from the burning of fossil fuels containing sulfur.
From Data to Action: How to Improve Air Quality
Knowing the air quality is the first step, but the ultimate goal is to improve it. As individuals, our decisions have an aggregated impact:
- Reduce private vehicle use: Opt for walking, cycling, or public transport.
- Energy efficiency: Use less electricity, especially from non-renewable sources.
- Support clean policies: Advocate for policies that promote renewable energy and industrial emission control.
- Indoor air quality: Use air purifiers, plants, and ensure good ventilation in your home.
"Clean air is a right, not a luxury."
This calculator is more than just a tool; it's a call to action. By understanding the data, we are empowered to be agents of change, both in our personal lives and in our communities, fighting for a healthier and more sustainable environment for all.

Frequently Asked Questions about Air Quality
The AQI is a scale used by government agencies to measure and report how clean or polluted the air is. It indicates the potential health risks associated with breathing that air on a given day.
When the AQI is high, it is dangerous for sensitive groups (children, the elderly, people with respiratory diseases). When the AQI reaches very high levels, it can be dangerous for the entire population.
Both are inhalable particulate matter. The difference lies in their size: PM10 particles are up to 10 micrometers in diameter, while PM2.5 particles are even finer (up to 2.5 micrometers). Due to their small size, PM2.5 particles can penetrate deeper into the lungs and cause more serious health problems.
Many governments and environmental organizations have real-time monitoring stations. There are also mobile apps and websites that provide real-time AQI data for your location, using data from these stations.
