Airthings 325 Corentium Home 2 vs Airthings Wave Plus

Airthings 325 Corentium Home 2 wins for most buyers: it is more affordable, better rated, lasts about twice as long per battery set, and shows readings on its own display. Airthings Wave Plus is worth the step up only when you want CO2, VOC and pressure sensing added to radon.

Focus versus breadth. The Corentium Home 2 is a dedicated radon monitor with temperature and humidity, presented on an LCD as simple Good, Fair or Poor averages. The Wave Plus has no screen but measures six things: radon, CO2, VOCs, temperature, humidity and atmospheric pressure.

No. Both the Airthings 325 Corentium Home 2 and the Airthings Wave Plus are Bluetooth-only, syncing with the Airthings app when in range. Each can join an optional Airthings Hub over SmartLink for continuous online data and remote access.

The Airthings Wave Plus confirms temperature, humidity and air quality alerts in the app, while the Airthings 325 Corentium Home 2 confirms air quality alerts. In day-to-day use the Corentium compensates with its always-visible on-device readout.

Choose Airthings 325 Corentium Home 2 if radon is the concern: it is the better-rated, more affordable option with an easy-to-read display, about 3 years of battery life, a 5-year warranty and support for Google Home, Alexa, Home Assistant and IFTTT.

Choose Airthings Wave Plus if you want one device watching your whole indoor air picture, adding CO2 for ventilation, VOCs for airborne chemicals and atmospheric pressure to the radon basics. It fits living spaces and bedrooms where stuffiness matters as much as radon.
