Questions
What does AQI measure?
AQI is a public reporting scale for outdoor pollutant levels and is usually published by government or monitoring sources.
Is AQI the same as indoor air quality?
No. Outdoor AQI can provide context, but indoor conditions depend on ventilation, filtration, sources, and room conditions.
Can an air purifier page give AQI health instructions?
No. BenchPicked pages use AQI as context and avoid health action instructions.
