You’ve probably read all about the importance of air purifiers in your home. They’re virtually required for ensuring you have clean air in your home and minimizing asthma and allergy symptoms. But have you ever wondered just how polluted the air is outside?
Luckily, numerous US government agencies put their heads together and created the the Air Quality Index (AQI). The AQI is designed to tell you how clean or polluted your air is, as well as to give you an idea of the potential health effects. On a scale of 0 to 500, the higher the AQI for your area, the worse your level of pollution. There are six basic categories of the AQI:
- 0-50: Good air quality
- 51-100: Moderate
- 101-150: Unhealthy for sensitive groups
- 151-200: Unhealthy
- 201-300: Very unhealthy
- 301-500: Hazardous
A value of 100 corresponds to the national standard for air quality, while anything greater than 300 would trigger emergency health warnings.
You can check out your current AQI forecast at AIRNow.gov. There you can get real-time AQI information for cities across the US, as well as learn more about how different levels of polluted air can affect your health. Just remember, the EPA also warns that indoor air can be up to five times more polluted than outside. So even though your town might never experience a wave of poor air quality, and air purifier might still be a good idea to keep your asthma and allergy symptoms at bay.
