Airthings · Airthings 2989 View Radon - Radon Monitor with Humidity & Temperature Detector - Battery Powered Mobile APP, WiFi, Alerts & Notifications
View on AmazonPrice and availability are shown on Amazon and can change at any time.
Verdict
The View Radon is a radon monitor with the connectivity of the View Plus and without the air quality sensors. Radon, humidity and temperature show on a customisable e-ink display and on the Airthings app and dashboard over Wi-Fi. It runs on six AA batteries for up to three years or on USB, and on USB it acts as a hub for other Airthings devices. If you want radon alerts on your phone while you are away, or you want to monitor a rental or a relative’s home, it is the model to pick. If you only want a number on a shelf, the Corentium Home 2 does that for less.

The Radon Sensor
Airthings describes the View Radon sensor as its most accurate and robust to date. As with all radon monitors, the reading is provisional at first and firms up over weeks; the app shows both short-term and long-term averages and explains the difference. For deciding whether mitigation is needed, use the long-term number and compare it with the guidance in choosing a radon monitor.
Display and Dashboard
The e-ink display can be configured to show up to four values, so a typical setup shows long-term radon, short-term radon, humidity and temperature. Waving a hand in front of the unit shows a colour-coded status. The Airthings app and web dashboard hold the history, support thresholds and notifications, and produce reports that you can share with a contractor. Because it is on Wi-Fi, notifications arrive whether or not you are home.
Power and the Hub Role
On batteries the View Radon samples at intervals that give the three-year figure. On USB power it samples more often and also becomes a hub, bringing Bluetooth-only Airthings devices online. That makes it a natural centre for a system built around a Wave Plus in the bedroom and a Wave Mini in the bathroom.
Strengths
- Wi-Fi radon monitoring with remote alerts.
- Battery option gives placement freedom.
- Readable, configurable display.
- Hub function for the rest of the Airthings range.
Limitations
- Radon, humidity and temperature only.
- Costs more than the Corentium Home 2 for the same core measurement.
- Six AA batteries to replace when the time comes.
How It Compares
The Corentium Home 2 is the offline alternative. The View Plus adds CO₂, PM2.5 and VOCs for a higher price. The Aranet Radon Plus offers a faster reading cycle and longer battery life but no Wi-Fi.

Frequently Asked Questions
Does the View Radon need Wi-Fi?
It is designed for Wi-Fi and the dashboard, but it also shows readings on its own display. Without Wi-Fi you lose remote alerts and the hub function.
How long do the batteries last?
Airthings quotes up to three years on six AA batteries with the default settings.
What does the hub function do?
On USB power the View Radon relays data from Bluetooth-only Airthings devices such as the Wave Plus or Wave Mini to the cloud.
Does it measure CO₂ or particles?
No. For those, the View Plus is the Airthings model.
