Airthings 2989 View Radon vs Aranet Radon Plus

Aranet Radon Plus takes the overall win with its higher owner rating, roughly 7-year battery life and extra pressure sensor. Airthings 2989 View Radon stays compelling for its Wi-Fi remote access, weekly reports, 5-year warranty and much wider smart home support.

Connectivity. The Airthings 2989 View Radon has 2.4GHz Wi-Fi, so radon levels, alerts and reports follow you anywhere, and it can act as a hub for other Airthings devices. The Aranet Radon Plus is Bluetooth-only with no cloud sync; you read its e-ink display, sync the app nearby, or bridge it through Home Assistant.

The Aranet Radon Plus: its two AA batteries are rated for around 7 years, and it even accepts rechargeable cells. The Airthings 2989 View Radon runs about 3 years on six AA batteries, though it uniquely offers USB-C power if you want to forget batteries entirely.

The Airthings 2989 View Radon works with Google Home, Alexa, Home Assistant and IFTTT. The Aranet Radon Plus integrates with Home Assistant only. Neither supports Apple HomeKit, SmartThings or Matter.

Choose Airthings 2989 View Radon if you want radon data and alerts wherever you are, weekly email reports, a 5-year warranty, and integration with Google Home, Alexa, Home Assistant and IFTTT, or if you plan to grow an Airthings sensor network around its hub role.

Choose Aranet Radon Plus if you want the best-reviewed radon readings of the pair on an always-on e-ink display with essentially no upkeep for years. It suits buyers who check the device in person or already run Home Assistant for remote dashboards and alerts.
