Knowing the detector is working properly gives me real peace of mind!

It’s extremely accurate, reasonably priced, and truly helps you feel safe at home. I’m very glad I purchased this detector-knowing my family is protected allows me to finally relax. Thank you!

Needs customizable alert levels.

I would give this five stars if the app allowed users to set custom notification thresholds. Currently, notifications are only sent when a category reaches a “Poor” (high) level. I’d prefer to set my own priorities or at least receive alerts at the “Fair” level (above “Good”), so I can take action before conditions become “Poor.”

Positive Review

Installation was incredibly easy-just insert the included battery and place the device where needed. Within minutes, it started tracking radon levels, and the clear digital display shows both the current reading and the 30-day average at a glance.

What I like most is the Bluetooth connectivity. It syncs seamlessly with the Airthings app, allowing me to view radon level trends over time and receive alerts when levels rise. The app interface is intuitive and user-friendly, making it ideal for long-term monitoring and giving me real peace of mind.

It turned out to be a very useful tool-I’m glad I bought it.

Assuming the data is accurate (since I don’t have another way to compare), it has definitely given us a much clearer understanding of our radon situation. The readings are easy to interpret and seem quite sensitive to differences in air quality between our unfinished basement area and the finished basement laundry room.

When we open the door from the laundry room to the unfinished area, the radon level rises from an acceptable range to an unacceptable one. This has been reassuring in some ways, while also prompting us to start thinking seriously about radon mitigation options.

Excellent radon detector!

Easy to set up, works reliably, and provides peace of mind by helping ensure that radon mitigation measures are effective.
