It tracks radon, temperature and humidity continuously, shows a green, yellow or red ring when you wave a hand over it, and feeds the same app history and trends as its sibling. The Airthings Wave Plus justifies its premium through breadth: it layers CO2, VOCs and atmospheric pressure onto the same radon, temperature and humidity, six sensors in one unit, so it can also flag stuffy air and airborne chemicals. Physically the two are near twins, screen-free and battery powered, syncing over Bluetooth with optional Airthings Hub support and working with Google Home, Alexa, Home Assistant and IFTTT. Pick the Airthings 2950 Wave Radon for radon-focused monitoring in a basement or crawlspace, and the Airthings Wave Plus if you want one device covering air quality broadly.

What the differences mean

Sensor set

The Airthings 2950 Wave Radon measures radon, temperature and humidity. The Airthings Wave Plus measures the same three and adds CO2, VOCs and atmospheric pressure, six sensors in total.

What the extra sensors change

On the Airthings Wave Plus the CO2 and VOC readings turn it into a ventilation tool, showing when a closed room gets stuffy or when cooking and cleaning load the air. The Airthings 2950 Wave Radon stays a radon instrument, with temperature and humidity as supporting context, which is all a mitigation check needs.

The rest is shared

The two are otherwise near twins: screen-free pucks with a wave-to-check ring, two AA batteries rated around 1.5 years, Bluetooth syncing, the same optional SmartLink hub support, the same app and the same Google Home, Alexa, Home Assistant and IFTTT support.

Which one to buy if

What owners say

Both monitors draw owners who want continuous radon tracking rather than a one-time test kit. Airthings 2950 Wave Radon owners praise how quickly it confirms a mitigation fan is working and how simple the wave-to-check ring and app are, while some complain about Bluetooth-only syncing and slow Airthings support. Airthings Wave Plus owners value the extra readings, describing VOC and CO2 levels that respond visibly to cooking, opened windows or boxes brought in from storage, and several credit it with revealing a radon problem; their common warnings are that the app and syncing can lag and that its radon numbers run low against charcoal lab kits.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
