What the differences mean

Radon versus CO2

The Airthings 2950 Wave Radon measures radon, temperature and humidity. The GoveeLife Smart Air Quality Monitor CO2 H5140 measures CO2, temperature and humidity. Neither sees particles, VOCs or carbon monoxide. The overall badge follows screen and the way the sheet scores the pair. It does not mean the CO2 panel can stand in for a radon test.

Screen and power

The GoveeLife Smart Air Quality Monitor CO2 H5140 has a 4.82 inch LED and must stay on USB-C. The Airthings 2950 Wave Radon has no screen, lights a colored ring when you wave, and runs about 1.5 years on two AA batteries. One is a desk panel that dies if you unplug it. The other is a puck you can leave in a crawlspace.

How the phone hears it

The GoveeLife Smart Air Quality Monitor CO2 H5140 uses 2.4 GHz Wi-Fi and Bluetooth, so the CO2 log can update while you are away. The Airthings 2950 Wave Radon uses Bluetooth and SmartLink to an Airthings hub, and it has no Wi-Fi radio. Without that hub, radon reaches the app when you open it nearby. Both still work with Google Home, Alexa and Home Assistant.

Warranty and the battery alert

The Airthings 2950 Wave Radon carries a 5 year warranty and can alert on a low battery. The GoveeLife Smart Air Quality Monitor CO2 H5140 carries a 1 year warranty and has no battery to warn about. Temperature, humidity and air quality alerts exist on both. The longer warranty sits on the radon meter even though the page recommendation is the CO2 panel.

What owners say

Owners of the two meters are solving problems that do not overlap. Airthings 2950 Wave Radon owners describe radon history that follows weather and a mitigation fan, a match to a lab test after 48 hours, and a wave-to-check ring. They complain that the app updates only when it is opened nearby and that support is slow and chat-only, with a minority seeing odd spikes. GoveeLife Smart Air Quality Monitor CO2 H5140 owners describe CO2 climbing in a closed office until they felt the slump, a large LED readable across the room, and alarms they set themselves. They complain about 2.4 GHz pairing and about people mistaking the meter for a carbon monoxide alarm.

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.
