There are many reasons why your Laser Egg’s readings may not match your locally published AQI:
- It depends on which AQI you’re using. Because different AQI standards use different criteria, the readings with the Chinese scale will not be the same as those of the US scale.
- Government published AQI is usually calculated from the pollutant with the highest concentration, which is not necessarily PM2.5. Check which pollutants your published AQI is measuring.
- Published AQI is taken from various monitoring stations in your region, whereas the Laser Egg shows readings from your current location. Air quality differs depending on where you are and other surrounding factors.
- Monitoring stations issue AQI are averaged over an hour and usually published several hours later, while Laser Egg readings are based off of real-time samples.
