Both measure radon, but the Aranet Radon Plus is the better radon monitor overall, winning on price, owner feedback, an IP20 rating, a rated 7 years of battery life against 1.5 years, and an E-Ink screen the Airthings Wave Plus does not have. The Airthings covers far more ground, adding CO2 and VOC sensing, SmartLink connectivity, Alexa and Google Home support and a 5-year warranty against 2. Both run on two AA cells, use Bluetooth and work with Home Assistant. Pick the Aranet Radon Plus for a focused radon reading you can glance at, and the Airthings Wave Plus for a multi-sensor view of the air.
