Our Verdict
Smart radon detector with 6-in-1 air quality monitoring including CO2, VOCs, humidity, temperature, and pressure.
Our Review
The Airthings Wave Plus is the gold standard for home radon monitoring. Unlike passive test kits that give you a one-time snapshot, this device provides continuous readings updated every hour — giving you a real understanding of how radon levels fluctuate throughout the day and across seasons.
Setup takes under 10 minutes. You simply mount it on a wall or set it on a surface, connect it to the free Airthings app on your smartphone, and it starts monitoring immediately. The app displays your radon levels with a clear color-coded indicator (green/yellow/red), along with trends over time.
What sets it apart from cheaper options is the professional-grade radon sensor, which meets the same accuracy standards used by radon mitigation professionals. Independent testing by the Norwegian Institute for Air Research (NILU) validated its performance against reference instruments.
The battery life lasts 1.5 years on two AA batteries, making maintenance minimal. For anyone serious about understanding their home's air quality comprehensively, this is the device we recommend most.
