Airthings 2989 View Radon vs Aranet Radon Plus comparison

Updated August 2026

Data from Amazon and official Airthings and Aranet sites.

2026 verdict

Pure measurement or connected convenience? The Aranet Radon Plus wins this radon monitor comparison on rating, battery life and sensors: owners rate it near the top of the category, its AA cells last around 7 years versus about 3, and it adds atmospheric pressure sensing plus a basic IP20 rating to the shared radon, temperature and humidity. The connected case belongs to the Airthings 2989 View Radon: built-in Wi-Fi for anywhere access, alerts and weekly reports, a SmartLink hub role, optional USB-C power, a 5-year warranty versus 2 and support for Google Home, Alexa, Home Assistant and IFTTT. E-ink displays grace both. If the number itself matters most, take the Aranet Radon Plus; if reaching that number from anywhere matters more, the View Radon earns its keep.
