Buy on Amazon USA
The Airthings View Plus is the more complete air quality monitor, measuring radon, CO2 and air pressure that the Amazon Smart Air Quality Monitor cannot. It shares PM2.5, VOC, temperature and humidity sensing with the Amazon, and adds a 2.9-inch E-Ink display, battery or USB-C power, temperature and humidity alerts, Google Home support and a 5-year warranty against 1. The Amazon Smart Air Quality Monitor is the inexpensive, well-liked alternative: it reads carbon monoxide, which the Airthings View Plus does not, sets up in minutes in the Alexa app and triggers Alexa routines straight from its readings. Choose the Airthings View Plus for serious whole-home monitoring with radon, and the Amazon Smart Air Quality Monitor for an Alexa home that wants cheap, responsive automation.

What the differences mean

Sensors

Both read PM2.5, VOCs, temperature and humidity. The Airthings View Plus adds radon, CO2 and air pressure; the Amazon Smart Air Quality Monitor adds carbon monoxide. For a basement or a stuffy bedroom the Airthings covers more, while the Amazon is the one that reacts to combustion gas.

Screen

The Airthings View Plus shows its readings on a 2.9-inch E-Ink display. The Amazon Smart Air Quality Monitor has no screen, only a coloured light, and everything else lives in the Alexa app.

Power and placement

The Airthings View Plus runs up to 2 years on six AA batteries or from USB-C, so it can sit anywhere. The Amazon Smart Air Quality Monitor has no battery and must stay plugged in over Micro USB.

Ecosystem

The Airthings View Plus works with Google Home, Alexa and Home Assistant. The Amazon Smart Air Quality Monitor works with Alexa and Home Assistant, needs an Echo to be useful, and is the one that can trigger Alexa routines from its readings.

Which one to buy if

What owners say

Owners of both are surprised by how quickly cooking, cleaning or a candle shows up in the readings, and both groups use them to decide when to ventilate or run a purifier. Airthings View Plus owners single out having radon and CO2 in the same unit, a Wi-Fi dashboard with exportable history and PM2.5 that agrees with outdoor reference sensors, and complain about CO2 drifting high without fresh air, fixed alert thresholds and an unlit screen. Amazon Smart Air Quality Monitor owners praise plug-and-play setup and Alexa routines that switch on a purifier with no hub, and complain that it is useless without an Echo, that the Alexa app is poor for data and that VOC readings throw false alarms.
