Airthings 2950 Wave Radon vs Aqara TVOC Air Quality Monitor

The Airthings 2950 Wave Radon is the better overall pick. It wins on owner rating, its 5-year warranty, longer battery life (about 1.5 years on AA cells) and more direct connectivity, and it includes a low-battery alert the Aqara lacks. The Aqara TVOC Air Quality Monitor is cheaper and adds an e-ink display and Apple HomeKit support, but as an air quality monitor it tracks VOCs rather than radon.

What each one senses. The Airthings 2950 Wave Radon is a dedicated radon monitor that also reports temperature and humidity, while the Aqara TVOC Air Quality Monitor measures TVOCs (airborne chemicals) plus temperature and humidity and has no radon sensor. If radon is your concern, only the Airthings covers it.

The Aqara TVOC Air Quality Monitor does. It is a Zigbee device that requires an Aqara hub to function and to reach Google Home, Alexa, Apple HomeKit, Home Assistant or IFTTT. The Airthings 2950 Wave Radon syncs directly to its app over Bluetooth on its own, and only optionally joins an Airthings hub over SmartLink for always-on remote data.

The Aqara TVOC Air Quality Monitor has an on-device e-ink screen; the Airthings 2950 Wave Radon has no screen and is read through its app or a wave-to-check colored ring. On battery life the Airthings runs about 1.5 years on AA cells versus roughly 1 year for the Aqara's CR2450 cells.

Anyone whose main goal is radon: basements, crawlspaces or tracking a mitigation system. The Airthings 2950 Wave Radon gives continuous radon, temperature and humidity data with a 5-year warranty and works with Google Home, Alexa, Home Assistant and IFTTT without a mandatory hub.

Owners already in the Aqara or Apple HomeKit ecosystem who want a compact VOC, temperature and humidity sensor with an on-device e-ink readout. The Aqara TVOC Air Quality Monitor adds Apple HomeKit support and a screen, but you will need an Aqara Zigbee hub and should not expect any radon measurement.
