Airthings Wave Plus vs GoveeLife Smart Air Quality Monitor CO2 H5140

The Airthings Wave Plus wins overall, thanks to a much broader sensor set covering radon, CO2, VOCs, temperature, humidity and pressure, plus a longer warranty and more smart home integrations. The GoveeLife Smart Air Quality Monitor CO2 H5140 answers with a typically lower price, a higher owner rating and a built-in display, so a tight budget or the need for a screen favors the GoveeLife.

Sensor coverage. The Airthings Wave Plus measures six things at once, including radon, which the GoveeLife Smart Air Quality Monitor CO2 H5140 does not detect at all. The GoveeLife instead focuses on CO2, temperature and humidity, with a display the Wave Plus lacks.

Only the GoveeLife Smart Air Quality Monitor CO2 H5140 has a built-in display, a large LED panel showing CO2, temperature, humidity and a clock. The Airthings Wave Plus has no screen; it uses a wave-to-check Good/Fair/Poor light and shows detailed numbers in its app instead.

Only the Airthings Wave Plus does. Along with radon it also tracks CO2, VOCs, temperature, humidity and atmospheric pressure. The GoveeLife Smart Air Quality Monitor CO2 H5140 has no radon sensor; it is a CO2, temperature and humidity monitor.

Anyone who wants one device covering radon plus the rest of the air-quality picture, or who is tracking a radon mitigation system alongside CO2 and VOCs, should choose the Airthings Wave Plus.

Buyers who only need to track CO2 and ventilation in a single room, and want a large, easy-to-read display with alarms and automation links to a fan or humidifier, should pick the GoveeLife Smart Air Quality Monitor CO2 H5140 instead.
