The Air Quality Index Explained Greener Ideal To measure and report on air quality, the epa uses the united states air quality index (aqi). the aqi is calculated by measuring each of the six primary air pollutants on a scale from “good” to “hazardous,” to produce a combined aqi numeric value 0 500. This updated guide explains what the aqi means, how it’s measured, recent 2024–2025 updates to air quality standards, and how you can interpret aqi levels for your own environment — both outdoors and indoors.
9 Air Quality Explained Ideas Indoor Air Quality Air Quality Air What is air quality? when air quality is good, the air is clear and contains only small amounts of solid particle and chemical pollutants. poor air quality, which contains high levels of pollutants, is often hazy and dangerous to health and the environment. Air quality is a measure of how clean or polluted the air around you is, based on the concentration of specific pollutants that affect human health. in the united states, it’s expressed as a single number called the air quality index (aqi), which runs from 0 to 500. Air quality is a measure of how clean or polluted the air is. monitoring air quality is important because polluted air can be bad for our health—and the health of the environment. The air quality index, or aqi, is the system used to warn the public when air pollution is dangerous. the aqi tracks ozone (smog) and particle pollution (tiny particles from smoke, power plants and factories, vehicle exhaust, and other sources), as well as four other widespread air pollutants.

The epa issues an air quality alert when pollutant concentrations are higher than 101 on the index, as this is the level at which people in sensitive groups—such as children, people with asthma, and those at risk of respiratory disease—begin to experience health hazards from poor air quality. Air pollution is the contamination of the air we breathe, indoors or outdoors, by any chemical, physical or biological agent that is potentially threatening to human and ecosystem health. What is the air quality index? the air quality index reflects the density of five pollutants in the air: ground level ozone, particulates, carbon monoxide, nitrogen dioxide, and sulfur. Learn about the air quality index (aqi) and its impact on health. discover how air pollution affects well being and ways to protect yourself.
