Local Haze crowdsources outdoor air quality data from many different sources and delivers it to your iPhone and Apple Watch. In release 2.3, as a Local Haze subscriber, you can now get air quality readings “at a glance” on your Apple Watch, widgets on your phone, and notifications for a sensor where significant changes in air quality have been detected. About Local Haze Local Haze reports air quality data from a variety of sensors across six continents, including AirGradient, AirNow, PurpleAir, Sensor.Community and uRADMonitor. In addition to viewing current air quality conditions, using Local Haze allows you to share sensor maps displaying air quality readings anywhere in the world. The World Health Organization and the U.S. Environmental Protection Agency (EPA) have developed guidelines for safe air quality as impacted by chemical pollutants and particulate matter (PM). PM smaller than 10 micrometers poses problems because it can enter the bloodstream. Local Haze displays the level of smaller PM 2.5 particles, which pose the most significant health risk.

Notifications will be sent to your phone when the air quality changes. How Local Haze Displays Air Quality Data Local Haze displays the EPA’s Air Quality Index (AQI) and a confidence rating for each sensor reading. The confidence rating is a feature that is unique to Local Haze and depends on many factors, including sensor maintenance and data freshness. Each AQ sensor reading is displayed as a face icon according to the key below, with a badge on the lower right that represents a confidence rating: Green Face: Air quality is Good. Air quality is considered satisfactory, and air pollution poses little or no risk. Yellow Face: Air quality is Moderate. Air quality is acceptable. For some pollutants, there may be a moderate health concern. Orange Face: Air quality is Unhealthy for sensitive groups. The general public is not likely to be affected, but people with heart and lung disease, older adults, and children are at greater risk. Red Face: Air quality is Unhealthy Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects. Black face mask with respirator: Air quality is Hazardous. Everyone may experience more serious health effects with possible emergency conditions. The entire population is likely to be affected. Note: The source for the above AQ index classification is from Air Quality Index (AQI) Basics - EPA: https://www.airnow.gov/aqi/aqi-basics/ The confidence rating badges are: Green badge with thumbs up: High confidence in the air sensor reading. Yellow badge with OK sign: OK confidence in the air sensor reading. Red badge with thumbs down: Low confidence in the air sensor reading. We hope you enjoy using Local Haze!
