Airthings 2950 Wave Radon vs Airthings 325 Corentium Home 2

Airthings 325 Corentium Home 2 comes out ahead. It is the newer model with a higher owner rating, it displays radon levels on its own LCD so you can read them without opening the app, and its batteries last about 3 years versus roughly 1.5 years on the Airthings 2950 Wave Radon. The Wave's main advantage is its broader in-app alert coverage.

The display. The Corentium Home 2 has a built-in LCD showing rolling radon averages with simple Good, Fair or Poor indicators, while the Wave Radon has no screen at all, relying on a wave-activated color ring and the app for numbers. Otherwise they are very similar: both measure radon, temperature and humidity over Bluetooth.

Neither the Airthings 2950 Wave Radon nor the Airthings 325 Corentium Home 2 has Wi-Fi. Both sync over Bluetooth when you open the Airthings app within range, and both can connect to an optional Airthings Hub via SmartLink for around-the-clock online data and remote access.

Choose Airthings 2950 Wave Radon if you want the fullest set of app notifications, including temperature, humidity, air quality and low battery alerts, and you like the quick wave-to-check gesture for an instant color-coded status. It offers the same radon sensing, 5-year warranty and platform support as the Corentium Home 2.

Choose Airthings 325 Corentium Home 2 if you want to read radon levels at a glance on the device itself, prefer the newer and better-rated design, and value the longer battery life of about 3 years. It is the more convenient everyday radon monitor for most homes, especially in basements where you want a visible readout.
