Airthings View Plus vs Amazon Smart Air Quality Monitor

The Airthings View Plus is the stronger overall device, winning on sensors, integrations, its e-ink screen and a longer 5-year warranty, with seven sensors including radon, CO2 and PM2.5. The Amazon Smart Air Quality Monitor is the more affordable, Alexa-focused alternative and earns a higher owner rating, but it measures fewer pollutants and only works with Alexa and Home Assistant.

What they measure and how they connect. The Airthings View Plus tracks seven pollutants including radon and CO2 and syncs over Wi-Fi with an e-ink display. The Amazon Smart Air Quality Monitor tracks five (VOCs, PM2.5, carbon monoxide, temperature and humidity), has no screen, must stay plugged in, and lives entirely inside the Alexa app.

No. Both cover VOCs, PM2.5, temperature and humidity, but the Airthings View Plus adds radon, CO2 and atmospheric pressure, while the Amazon Smart Air Quality Monitor instead measures carbon monoxide (CO). Neither device is a substitute for a certified CO alarm.

It depends on your platform. The Amazon Smart Air Quality Monitor can trigger Alexa routines directly from its readings without a hub, which is ideal for automating a purifier in an Alexa home. The Airthings View Plus works with Google Home, Alexa, Home Assistant and IFTTT, giving broader platform choice and remote access over Wi-Fi.

Choose the Airthings View Plus if you want one device that monitors radon, CO2, particulates and VOCs, prefer Wi-Fi with remote access and an on-device screen, and value a 5-year warranty. It suits anyone serious about whole-home indoor air quality.

Choose the Amazon Smart Air Quality Monitor if you already use Alexa and want an inexpensive, responsive sensor to watch cooking, cleaning and renovation and to automate a purifier. Just note it needs an Echo, has no screen, and does not measure radon or CO2.
