Airthings Wave Plus Radon & Indoor Air Quality Monitor review
Radon and CO2 monitoring in a home that already has, or is willing to add, an Airthings hub.
By Tom Calder · Price last checked 20 Sep 2026, 12:29 BST · price-tracked
Radon, CO2 and VOC sensing with a claimed 16-month battery life is a lot of measurement for the money. The catches are structural rather than minor: no PM2.5 sensor, no numeric screen, and no continuous cloud sync unless you buy a SmartLink hub or already own a View-series monitor — so remote alerts cost more than the headline price. Like every other Airthings here, it has no carbon monoxide sensor.

- Radon, CO2 and VOC sensing for around £20 less than the View Plus
- 2x AA lasts a claimed 16 months, or 18 months when connected via SmartLink
- Works with Alexa, Google Assistant, IFTTT and Homey, though not for radon readings
- No PM2.5 sensor, so cooking, wood smoke and traffic particles go unmeasured
- Remote access needs a separate SmartLink hub or a View-series monitor — a second purchase the headline price hides
- No numeric display, so every actual figure lives in the app rather than on the device
Who shouldn't buy this
you want particulate readings or a screen — the View Plus adds both for a modest step up in price.
