Airthings 2950 Wave Radon vs Amazon Smart Air Quality Monitor

Airthings 2950 Wave Radon has the stronger overall profile: a higher owner rating, a 5-year warranty versus 1 year, support for Google Home, Alexa, Home Assistant and IFTTT, and a fuller alert set. The Amazon Smart Air Quality Monitor is much cheaper and senses more pollutant types, but it only works with Alexa.

What they measure. The Airthings unit is a radon monitor that also tracks temperature and humidity, while the Amazon unit measures VOCs, PM2.5 particulates, carbon monoxide, temperature and humidity but has no radon sensing at all. They solve different problems, so many households would actually want each for a different room.

Not usefully. It integrates only with Amazon Alexa and needs an Echo device for setup, readings and alerts; there is no Google Home, HomeKit, SmartThings, Home Assistant or IFTTT support. The Airthings 2950 Wave Radon works with Google Home, Alexa, Home Assistant and IFTTT through the Airthings app.

The Airthings 2950 Wave Radon runs about 1.5 years on two AA batteries, so you can place it anywhere radon matters, like a basement or crawlspace. The Amazon Smart Air Quality Monitor has no battery and must stay plugged in over Micro USB, which limits placement to spots near an outlet.

Choose Airthings 2950 Wave Radon if radon is a concern in your area or you want to verify a mitigation system. It monitors continuously on battery power, keeps history in the app, and is backed by a 5-year warranty and broad smart home support.

Choose Amazon Smart Air Quality Monitor if you are an Alexa household wanting inexpensive monitoring of VOCs, particulates and carbon monoxide, especially to automate a fan or air purifier through Alexa routines. Just remember it does not measure radon and is not a substitute for a certified CO alarm.
