The Air Quality Index (AQI) also known as the Air Pollution Index (API) or Pollutant Standard Index (PSI)), is an indicator of air quality, based on pollutants that have adverse effects on human health and the environment.
We must preserve the quality of air. We must do it by planting more trees.
We can preserve the air quality by banning CFC's. They react with ozone and deplete it.
The term "ion" on your fan refers to the ionizer feature. This feature releases negative ions into the air, which can help improve air quality by reducing allergens, pollutants, and odors.
The A.A.C.O.G distributes an AIR QUALITY HEALTH ALERT to local media, schools, government agencies, and businesses.
