Live air quality index and PM levels for your location.
Free to use, no sign-up required. Air Quality is one of 198 tools built into Xenition, alongside a chat that can use them for you.
Shows the current air-quality index and fine particle levels for your location, with a pollution map around you. Check it before running or cycling.
Readings come from the Open-Meteo air-quality API. For locations between longitudes −170° and −30°, the Americas, the number is Open-Meteo’s US AQI; elsewhere it is Open-Meteo’s European AQI. US AQI uses the EPA bands: 0–50 Good, 51–100 Moderate, 101–150 Unhealthy (sensitive), 151–200 Unhealthy, 201–300 Very unhealthy, above 300 Hazardous. European AQI uses 0–20 Good, 20–40 Fair, 40–60 Moderate, 60–80 Poor, 80–100 Very poor, above 100 Extremely poor. The map is a Windy embed of CAMS PM2.5.
The card shows a whole number coloured by its band, the band name, and two tiles such as PM2.5 with one decimal in µg/m³ and PM10 in the same unit.
On the US scale, 101 to 150 is unhealthy for sensitive groups: children, older adults and people with heart or lung conditions should cut back long or heavy outdoor exertion.
PM10 is particles up to 10 micrometres, like dust and pollen. PM2.5 is the finer part, from smoke and traffic, which reaches deep into the lungs.
You do not have to open Air Quality to use it. Ask Xenition in plain language and it runs the right tool, then carries the answer into whatever you are working on — a document, a spreadsheet, a deck.
