Airthings Wave Plus vs Aranet Radon Plus

Airthings Wave Plus wins the overall comparison thanks to its six-sensor breadth (adding CO2 and VOCs), 5-year warranty, four smart home integrations and fuller alerts. Aranet Radon Plus counters with a higher owner rating, an e-ink display, roughly 7 years of battery life and its strong radon accuracy record.

Breadth versus focus. The Airthings Wave Plus is a general indoor air monitor that includes radon among six measurements. The Aranet Radon Plus is a dedicated radon instrument with temperature, humidity and pressure as context, a visible display and near-zero maintenance. Only the Airthings measures CO2 and VOCs.

The Aranet Radon Plus shows readings on an always-on e-ink screen and runs around 7 years on two AA batteries. The Airthings Wave Plus has no screen, relying on its wave-to-check color ring and the app, and needs fresh batteries roughly every 1.5 years.

The Airthings Wave Plus, with Google Home, Alexa, Home Assistant and IFTTT support plus an optional Airthings Hub for continuous cloud data. The Aranet Radon Plus integrates with Home Assistant only and has no Wi-Fi or cloud sync.

Choose Airthings Wave Plus if you want radon monitoring folded into a wider air quality picture with CO2 and VOCs, broad platform support and a 5-year warranty, and you do not mind Bluetooth syncing or adding a hub for remote access.

Choose Aranet Radon Plus if radon is the mission: it is the higher-rated device, its readings track lab tests, its e-ink display is always current, and its battery lasts years. Ideal for basements and mitigation follow-up, especially in a Home Assistant household.
