What is an Air Quality Index (AQI)?
Air Quality is a complex topic that can be confusing to understand: especially when it's unclear what the data you're looking at means. An AQI attempts to simplify air quality data and make it digestible. -
Why Air Quality Maps Have Different Data
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. -
Outdoor Air Pollution: Carbon Monoxide
CO or Carbon Monoxide is a colorless and oderless gas. If inhaled constantly or the concentrations are too high, it can affect our health severely. -
Air Quality Index Guide: What Should You Do in Each Level?
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. -
Are Ultrasonic Humidifiers a Source of PM2.5?
Learn why ultrasonic humidifiers can become a source of particulate matter pollution in your home in this guide. -
What to do About Indoor Air Quality During Wildfires?
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. -

How to Reduce Exposure To Air Pollution & High levels of PM2.5
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. -
Hyper-local, Real-time Air Quality Map
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. -
What is Particulate Matter (PM)?
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.
