What is a "rolling average"?
E.g. the 24h rolling average means the last 24h, it updates hourly by adding new data and removing old. 24h and 7-day averages reveal recent trends, readings above your long-term average indicate rising levels, while readings below suggest a decline.
How long should I measure for radon?
Radon levels fluctuate, so measure for several weeks. For best results, test during fall/winter months and consult with local authorities. With a mitigation system, continuous monitoring confirms if it’s working and alerts you to any problems.
Can I use the detector without the Airthings app?
Yes, you can. But the app provides detailed historical graphs, past data, and personalized insights to help you understand and manage radon levels. It's completely free with no in-app purchases, offering more value than viewing data alone.
Why wait 24 hours for first radon values?
Unlike temperature or humidity, radon levels can change significantly hour by hour. That’s why we use averages instead of single readings. Your device displays its first 24-hour average after a full day of data, giving a clearer view of radon trends.
Why should I choose Airthings for radon monitoring?
Our patented sensor has proven reliable since 2011 for both homeowners and professionals. Through the Airthings app, you get personalized guidance to understand and manage your home's radon levels effectively.
