Airthings Wave Mini vs GoveeLife Smart Air Quality Monitor CO2 H5140

The GoveeLife Smart Air Quality Monitor CO2 H5140 wins overall, thanks to a typically lower price, a higher owner rating and a built-in display. The Airthings Wave Mini fights back with a longer warranty and more smart home integrations, so the pick depends on whether you value a screen and price or a broader ecosystem and VOC sensing.

The sensors and connectivity differ. The Airthings Wave Mini measures VOCs, temperature, humidity and mold risk over Bluetooth only, with no display of its own. The GoveeLife Smart Air Quality Monitor CO2 H5140 measures CO2, temperature and humidity instead, and shows all of it on a large LED screen over Wi-Fi and Bluetooth.

Only the GoveeLife Smart Air Quality Monitor CO2 H5140 has a display, a 4.82 inch LED panel showing CO2, temperature, humidity and a clock. The Airthings Wave Mini has no screen and relies entirely on its app for readings.

The Airthings Wave Mini provides a mold-risk indicator derived from its humidity and temperature readings, which is unusual among budget monitors. The GoveeLife Smart Air Quality Monitor CO2 H5140 has no mold-risk feature; its focus is CO2, temperature and humidity.

Anyone who wants an affordable, readable CO2 monitor for a home office or bedroom, with alarms and automation links to a fan or humidifier, should choose the GoveeLife Smart Air Quality Monitor CO2 H5140.

Owners already running an Airthings hub or View Plus who want a cheap secondary sensor for VOCs, humidity and mold risk in an extra room, and who value Home Assistant and IFTTT support, should pick the Airthings Wave Mini instead.
