Data from the official Airthings and Aranet sites.
2026 verdict
Wave-to-check light or always-on E-Ink? The Aranet Radon Plus is the better radon monitor of the two, showing its reading on a screen and running far longer on its batteries.
It is rated for 7 years on two AA cells against 1.5 years for the Airthings 2950 Wave Radon, adds an air pressure sensor, and refreshes radon every 10 minutes. The Airthings 2950 Wave Radon answers with a 5-year warranty against 2, Google Home and Alexa support on top of Home Assistant, and the option to join an Airthings hub for remote data, and it is the lower priced of the pair. Both are Bluetooth only and track radon, temperature and humidity. Choose the Aranet Radon Plus for a low-maintenance radon monitor you can read at a glance, and the Airthings 2950 Wave Radon for a voice assistant home or an existing Airthings hub.

What owners say
Owners of both radon monitors say readings line up with lab tests once the device has settled, and both groups watch radon drop after a mitigation fan is switched on. Aranet Radon Plus owners praise the quick 10-minute readings, the comfortable E-Ink screen, years of battery and Home Assistant alerts, and mention short Bluetooth range from a basement and no cloud sync. Airthings 2950 Wave Radon owners like the wave-to-check ring and one-minute setup, and several connected it to an Airthings hub, while their complaints are syncing only when the app is opened nearby, slow, chat-only support and a minority seeing inconsistent readings or false spikes.
