The Plume Air Quality Index (AQI) is a tool that gives you an immediate overview of the air quality in your environment, just as a weather report might give you an indication of the temperature outside. The Plume AQI has six levels of pollution, or thresholds, which are linked to the exposure limits outlined by the World Health Organisation (WHO). Each category represents the amount of time it is safe to spend in a certain level of pollution. For example, if the Plume AQI is under 20, the air quality is considered low pollution and is perfect for outdoor activities. However, if the AQI exceeds 100, the air is considered very highly polluted and everyone may start to experience serious health effects. Plume Labs uses the Plume AQI to provide live and forecast air quality data through its app, which helps users stay away from pollution hotspots and take steps towards improving their health and wellbeing.

The Plume Air Quality Index (AQI) is based on World Health Organisation (WHO) guidelines
The Plume Air Quality Index (AQI) is a tool that gives an immediate overview of the air one is breathing, similar to how temperature provides a first indication of the weather outside. The Plume AQI is based on World Health Organisation (WHO) guidelines, as well as international standards developed by organisations like the United States Environmental Protection Agency (EPA) and other scientific studies.
The WHO guidelines, along with other global institutions' standards, help define the Plume AQI and its seven associated categories. Each category of the Plume AQI indicates the length of time one can be exposed to specific pollutant rates without adverse health effects. The six levels of pollution or thresholds are linked to the exposure limits outlined by the WHO. These thresholds are:
- Low Pollution (0-20): The air quality is considered clear and perfect for outdoor activities. Pollution levels are under the recommended exposure thresholds set by the WHO for one year of pollution exposure.
- Moderate Pollution (21-50): Air quality is acceptable, though it exceeds the recommended WHO threshold for one year.
- High Pollution (51-100): The air is highly polluted and above the WHO's 24-hour exposure recommendations. People may start to feel adverse health effects, and those sensitive should take precautions during outdoor activities.
- Very High Pollution (101+): Everyone may experience serious health effects, and long-term exposure poses a significant health risk. Levels have exceeded the WHO's recommended exposure threshold for one hour.
The overall Plume AQI value is determined by the pollutant with the highest concentration, with the index taking into account various harmful pollutants. The higher the value of the AQI, the more polluted the air and the greater the potential health risks. The Plume AQI provides actionable information, empowering individuals to take steps to protect their health and wellbeing.

The Plume AQI has six levels of pollution, or thresholds, linked to WHO exposure limits
The Plume Air Quality Index (AQI) provides an immediate overview of the air one is breathing, much like how temperature provides a first indication of the weather outside. The Plume AQI has six levels of pollution, or thresholds, linked to the exposure limits outlined by the World Health Organisation (WHO).
The thresholds are based on the WHO's annual, daily, and hourly exposure guidelines, as well as guidelines from other global institutions, including the European Commission, the Chinese Air Quality Standards, and the United States Environmental Protection Agency (EPA). Each category of the Plume AQI indicates the length of time one can be exposed to certain pollutant rates without adverse health impacts. This allows individuals to take proactive measures to protect their health and wellbeing.
The six levels of pollution thresholds are as follows:
- 0-20: Low Pollution - At this level, the air is considered clear and perfect for outdoor activities. Pollution levels fall under the WHO's recommended exposure thresholds for one year of pollution exposure.
- 21-50: Moderate Pollution - While the air quality is still acceptable, it exceeds the WHO's recommended threshold for one year.
- 51-100: High Pollution - The air quality is highly polluted and surpasses the WHO's twenty-four-hour exposure recommendations. People may begin to experience adverse health effects, especially those with sensitivities, who should exercise caution during outdoor activities.
- 101 and above: Very High Pollution - At this level, everyone may experience more serious health effects, and long-term exposure poses a significant health risk. The pollution levels have exceeded the WHO's recommended exposure threshold for one hour. In certain regions or during exceptional pollution peaks, levels may even reach 200 or 300, constituting emergency conditions with potential harmful impacts on the general public, even from short-term exposure. All individuals are advised to refrain from physical activities until pollution levels decrease.
The Plume AQI takes into account the concentrations of various harmful pollutants and is calculated based on the pollutant with the greatest impact on one's health at a given time.

Each category represents the amount of time it is safe to spend in that level of pollution
The Plume Air Quality Index (AQI) provides an immediate overview of the air quality in a given location, similar to how temperature provides an indication of the weather. The Plume AQI is based on World Health Organization (WHO) guidelines, international standards developed by entities like the United States Environmental Protection Agency (EPA), and other scientific studies. It takes into account the concentrations of various harmful pollutants.
The Plume AQI has seven associated categories, each indicating the length of time one can be exposed to specific pollutant rates without adverse health impacts. Here is an overview of each category and the recommended amount of time it is safe to spend in that level of pollution:
0-20: Low Pollution
This category indicates low pollution levels, with the air considered clear and perfect for outdoor activities. Pollution levels fall under the recommended exposure thresholds set by the WHO for one year of pollution exposure. It is safe to spend extended periods in this level of pollution without any immediate health concerns.
21-50: Moderate Pollution
Air quality is acceptable, but it exceeds the recommended WHO threshold for one year. While it may not pose immediate health risks, prolonged exposure over extended periods may have cumulative adverse effects. It is generally safe to spend a few hours in this level of pollution, but it is recommended to limit excessive physical activities, especially for sensitive individuals.
51-100: High Pollution
The air quality in this category is considered highly polluted and exceeds the WHO's 24-hour exposure recommendations. Everyone may start to experience adverse health effects, and those with sensitivities should exercise caution when engaging in outdoor activities. It is generally safe to spend a limited amount of time, such as a couple of hours, in this level of pollution, but it is important to monitor any physical reactions and take necessary precautions.
101+: Very High Pollution
At this level, everyone may experience more serious health effects, and long-term exposure poses a significant health risk. Levels have exceeded the recommended WHO exposure threshold for one hour. In such conditions, all individuals, regardless of sensitivities, should avoid physical activities until pollution levels decrease. It is not advisable to spend prolonged periods in this level of pollution, and if exposure is necessary, it should be minimized as much as possible.
The Plume AQI categories provide a useful guide to understanding the safety implications of different levels of pollution. However, it is important to note that even in moderate pollution levels, certain sensitive groups, such as children, the elderly, or those with pre-existing health conditions, may still experience adverse effects. Therefore, it is always advisable to monitor personal health and take appropriate precautions when exposed to any level of air pollution.
