Frequently Asked Questions
What is AQI?
Air Quality Index (AQI) is a scale from 0-500 measuring air pollution levels. It accounts for PM2.5, PM10, ozone, NO₂, SO₂, and CO. AQI above 100 is considered unhealthy for sensitive groups.
What is PM2.5?
PM2.5 are fine particles less than 2.5 micrometers in diameter — small enough to enter your lungs and bloodstream. Sources include wildfire smoke, vehicle exhaust, and industrial emissions. It's the most health-relevant pollutant in AQI.
Do air purifiers help with poor AQI?
Yes, HEPA air purifiers can reduce indoor PM2.5 by 50-80%. Run them on high during poor AQI days with windows closed. A $100-200 HEPA purifier is one of the best health investments for areas with frequent air quality issues.

Yes, completely free with no signup required. Use it as many times as you need — there are no limits or hidden fees.
