Why AQI Matters?
Local air quality affects how we live and breathe. Like the weather, it can change from day to day or even hour to hour. The U.S. Environmental Protection Agency (EPA) and our local air quality agency have been working to make information about outdoor air quality as easy to find and understand as weather forecasts. A key tool in this effort is the Air Quality Index or AQI. EPA and local officials use the AQI to provide simple information about your local air quality, how unhealthy air may affect you, and how you can protect your health.
AQI measures how polluted the air is and as AQI rises, health risks increase. Different Nations have their own AQI and health standards. Computation of the AQI requires the accurate measurement of an air pollutant concentration over a specified period, specifically ground-level ozone, particle pollution, Carbon Monoxide, and Sulfur Dioxide. Two micro pollutants particularly PM2.5 and PM10 are measured to determine AQI.
Air Quality Index

The AQI can increase due to a rise in harmful air emissions like during rush hour traffic, industrial production peak-time or crop burning. Also stagnant air, temperature changes, and low wind speeds lead to increased pollution levels.
Indoor Air Quality
can be worse than you can imagine!
Since the air inside our homes and offices often get trapped because of inadequate ventilation, the Indoor Air Quality (IAQ) can be much worse than the air quality outdoors. Again, since we have to take adequate measures like keeping the windows closed to reduce the dust and polluted air from outside entering inside, it becomes a tricky situation. An oxygen generator is a viable solution!
