The device is battery-powered, facilitating easy placement without the need for cables.

The customizable eInk screen and visual alarms provide clear and immediate feedback on air quality levels. Additionally, the Airthings app enhances ease of use by allowing users to check live data, receive notifications, and analyze trends over time.

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.
