However, the device relies heavily on internet access and requires an Airthings account for operation, which might be a drawback for some users.

It is accurate in detecting radon, with a measurement accuracy of around 10% after 7 days at 5 pCi/L. The operating temperature range (4 to 40°C / 39 to 104°F) and humidity threshold (<85%) are suitable for typical indoor conditions. The monitor's average battery life is around two years, and it includes six AA batteries.

Additionally, the ability to generate radon self-inspection reports is a practical feature for users who want documented evidence of their radon levels over time.

Its lightweight and compact design add to its ease of use, making it suitable for nearly any household setting. However, there are a few drawbacks. The device's accuracy, while generally reliable, can be influenced by environmental factors such as humidity, which can reach up to 95% for optimal operation. Also, it operates within a temperature range up to 104 degrees Fahrenheit, which might be limiting for homes in hotter climates. Despite these minor limitations, the Airthings Corentium Home Radon Detector provides a user-friendly and effective solution for long-term radon monitoring, making it an excellent choice for those seeking peace of mind about their indoor air quality.
