Follow outdoor readings & take action: Keep an eye on otherwise invisible outdoor air pollution with the AirVisual app. Use an air monitor to ensure your indoor air quality is always in the “green” and run an air purifier when air quality exceeds standards. As a result, maintaining premium indoor air quality is of utmost importance. Maintain excellent indoor air quality - We generally spend 80+% of our time indoors. However, it is perfectly possible to breathe world-class, healthy air even in a polluted city as long as you take the right precautions to protect yourself. Living in a polluted environment can be challenging.

The index formula usually considers up to 6 main pollutants (PM2.5, PM10, carbon monoxide, sulfur dioxide, nitrogen dioxide and ground level ozone), and calculates the respective health risk (or AQI number) for each one. Meanwhile in particularly sandy or dusty places, PM10 will be the main pollutant.ĪQI, or Air Quality Index, is a system for translating sometimes confusing or unintuitive pollutant concentration measurements, into one easy-to-understand scale to clearly represent the health risk posed by air pollution. Sometimes in hot summer months, however, Ozone will be the main pollutant. For this reason, PM2.5 is most often the “main pollutant” in the air, dictating overall AQI. It's near microscopic size means that it is so small it can be absorbed into the bloodstream upon inhalation - causing a variety of effects on a number of organs. PM2.5 is generally the most prevalent pollutant present at harmful levels. Which air pollutants are most dangerous?.

Of these six key pollutants, generally PM2.5, PM10 and Ozone are the most likely to reach unhealthy levels. These pollutants include: PM2.5, PM10, carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2) and ground level ozone (O3). There are six key pollutants which are frequently measured by government monitoring stations, and used to calculate overall AQI.

As a result, real-time air pollution data and awareness is critical to protecting yourself from adverse effects.īy enabling location services and notifications on the AirVisual app, you can rest assured you are always informed of pollution spikes, wherever you are. Air pollution is dynamic and can change in as little as a few minutes based on weather patterns, polluting sources, human behavior, and other variables. There is no concrete answer for how your city’s air quality fairs.
