Airthings Wave Plus vs GoveeLife Smart Air Quality Monitor CO2 H5140

The Airthings Wave Plus wins overall, on the back of a much broader sensor set covering radon, CO2, VOCs, temperature, humidity and pressure, plus a longer warranty. The GoveeLife Smart Air Quality Monitor CO2 H5140 answers with a typically lower price, a stronger owner rating and a built-in display.

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 or Poor light and shows detailed numbers in its app instead.

No. It measures carbon dioxide, which is about ventilation and stuffiness, not the poisonous carbon monoxide a safety alarm detects, and neither it nor the Airthings Wave Plus is a substitute for a dedicated CO alarm.

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.
