Airthings Wave Plus review
Airthings Wave Plus Radon & Indoor Air Quality Monitor
By Tom Calder
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.
- Best for
- Radon and CO2 monitoring in a home that already has, or is willing to add, an Airthings hub.
- Skip it if
- You want particulate readings or a screen

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- Radon, CO2 and VOC sensing for 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
Worth knowing
- 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
Don't buy it if you want particulate readings or a screen — the View Plus adds both for a modest step up in price.
