BelAIR air quality app The BelAIR app gives a score, ranging from "very good" to "horrible", of the current air quality everywhere in Belgium. The app also makes a forecast of the air quality for the next few days and gives an idea of the long-term evolution of air quality. Measuring and modelling The three regions in Belgium have a network of more than 100 automatic measuring stations that measure the air quality very accurately. However, it is impossible to deploy these expensive devices everywhere. Using computer programmes, we calculate the air quality in places where no measurements are made. Together with the available measurements, an estimate of the air quality at each location in Belgium can then be made. BelAQI air quality index How good or bad the current air quality is depends on the concentrations of different substances in the air. The BelAQI air quality index is used to assess the air quality. It gives the air quality a rating from "very good" to "horrible". To calculate the BelAQI, the concentrations of various substances (nitrogen dioxide, particulate matter and ozone) are taken into account. For these substances, an individual assessment is made based on the short-term health effects. The worst assessed determines the overall BelAQI. Air quality in the long term The BelAIR app not only gives an idea of the day-to-day (or sometimes even hour-to-hour) variation in air quality at a location at the moment, but also gives an idea of the air quality in the long term. The annual average concentrations for a location are compared with the European limit values and the World Health Organisation's health advisory values. This gives an idea of the long-term impact of air pollution on health. ## Key features - Real-time air quality scores - Air quality forecasts - Long-term air quality evolution - BelAQI index explanation - Pollutant concentration data - Health impact insights ## Recent user reviews (10 of 49) All indexed reviews: https://appshunter.io/ios/app/belair/id1441924418/reviews.md ### 4/5 — Good but *2026-01-29, version 3.0.69* please fix the sheet with the details that does not come up easily. ### 3/5 — Nut? *2025-12-13, version 3.0.65* Je kan meldingen maken via de app, maar het is onduidelijk wat daarmee gebeurt. Komt niet overeen met wat screenshots tonen. Ik kan geen map zien. ### 2/5 — Geen beterschap door de jaren heen met PUBLIEK geld ! ? *2025-05-26, version 3.0.57* Kleuren kloppen niet EN zwart scherm bij start FOEI !! ### 3/5 — Interessant maar interface bugs op iOs *2023-05-19, version 1.8.3* Kan niet meer tussen verschillende locaties swipen zoals in eerdere versies ### 2/5 — What means Good in this App? *2022-05-08, version 1.8.0* I took some screenshots and I’m wondering how the score can be Good when the values are far above the yearly average. Like ozon today 8 May 64microgram vs average of 47microgram: I don’t call this Good. Like NO2 on 10 January 33 micrograms vs average of 14 micrograms: I don’t call this Very Good. In the app there is no communication channel foreseen and it isn’t indicated who is responsible for the data. I don’t understand neither that an app is made differently from the international peers. Is it to keep us dum? ### 1/5 — Looks slick but too complicated *2022-03-21, version 1.8.0* What I liked about the previous version is that you immediately saw the map with overall air quality across the region/Belgium. Now it takes complicated navigation to find the map which covers less than 1/3rd of the screen. ### 5/5 — Efficace *2021-08-01, version 1.8.0* Simple et efficace, rien à dire ### 2/5 — Geen verbetering *2021-07-24, version 1.8.0* De app is er sinds de laatste update op achteruitgegaan. Jammer dat de functie om altijd automatisch de huidige locatie te gebruiken is verdwenen. ### 1/5 — Bel air *2021-06-21, version 1.8.0* Zeer zeer slechte update vorige was veel veel beter ### 1/5 — Review *2021-06-19, version 1.8.0* Waar zijn de grafieken met uurwaarden van de vroegere app gebleven ? Deze nieuwe app geeft veel minder info. Verscheidene stappen achteruit ! Geef ons terug de info van de vroegere app ! ## Frequently asked questions about BelAir ### What is the BelAIR air quality score?
