Airthings 2950 Wave Radon vs GoveeLife Smart Air Quality Monitor CO2 H5140

The Airthings 2950 Wave Radon comes out ahead overall, with a longer warranty, wider smart home integrations (Google Home, Alexa, Home Assistant and IFTTT) and a fuller alert set. The GoveeLife Smart Air Quality Monitor CO2 H5140 answers back with a lower typical price, a stronger owner rating and a built-in display, so the right choice depends on whether radon or CO2 is the pollutant you actually need to track.

They measure different things. The Airthings 2950 Wave Radon is a dedicated radon detector that also reads temperature and humidity, running on AA batteries with Bluetooth only and no screen. The GoveeLife Smart Air Quality Monitor CO2 H5140 measures CO2 instead of radon, plugs into mains power over USB-C, and shows live readings on a large LED display.

No, the Airthings 2950 Wave Radon runs entirely on 2x AA batteries, which is useful for placing it in a basement or crawlspace without an outlet nearby. The GoveeLife Smart Air Quality Monitor CO2 H5140 has no battery option and needs a mains outlet over USB-C for continuous monitoring.

The GoveeLife Smart Air Quality Monitor CO2 H5140 has a large LED panel showing CO2, temperature, humidity and a clock. The Airthings 2950 Wave Radon has no screen at all; instead it uses a wave-to-check gesture that lights a colored ring, with full numbers and history available in its app.

Homeowners concerned about radon in a basement, crawlspace or ground-floor room, or anyone tracking a radon mitigation system, should choose the Airthings 2950 Wave Radon, since it is the only one of the two that actually measures radon.

Anyone who works or sleeps in a closed room and wants to catch CO2 buildup, with a readable display and configurable alarm thresholds, should pick the GoveeLife Smart Air Quality Monitor CO2 H5140 instead, since it does not test for radon at all.
