Transboundary air pollution harms the air we breathe every day. Learn about the phenomenon and what you can do to combat poor air quality in your area.
Knowing why air quality maps have different data helps you choose the most accurate one to trust. Here’s an in-depth explanation to understand discrepancies.
Particle pollution is one of the most common pollutants, and often it is not clear what we can or should do at each air quality index level. There are six levels, from good to hazardous.
During a wildfire, the fire itself, the smoke and ashes can affect your health. Learn about how higher concentrations of particulate matter are so unhealthy to breathe.
When the AQI (Air Quality Index) in your area shows extremely high levels of PM2.5 or your PurpleAir sensor shows a health alert, it means that pollution is hazardous at these levels. Consider these steps to reduce your exposure.
The air we breathe has direct consequences on our health. According to The NOAA, "Poor air quality is responsible for an estimated more than 100,000 premature deaths in the U.S each year". PurpleAir has designed a hyper-local, real-time air quality map that targets the need to measure and visualize air quality.
PM - which stands for particulate matter or particle pollution - is an intricate mixture of liquid droplets made up of acids (like nitrates and sulfates), ammonium, water, black carbon, organic chemicals, metals, soil material, and air-borne particles.
