Air Quality (AirVisual) Which scale does it use?

The AirVisual app utilizes the air quality index (AQI) scales from the US and China.

AQI is calculated in various ways globally. China and the US have the most widely used systems, with the US index becoming the world's standard.

This index ranges from 0 to 500, where higher values indicate higher air pollution levels and adverse effects on health.

According to the US AQI standard, an index of 100 or above is considered unhealthy for health.

PM 2.5-10 refers to airborne particles in the air with a diameter smaller than or equal to 2.5-10 micrometers. Particles with a diameter less than 10 micrometers can be inhaled by humans when breathing, accumulating in the lungs and posing health risks. Particles with a diameter less than 2.5 micrometers are particularly hazardous as they directly infiltrate the lung sacs.

If the app doesn't display the PM2.5 index on the interface, you can activate it by going to Settings (gear icon) > Enable PM2.5 Concentration.
