2026 verdict
Locked into Alexa, or open to more? The SONOFF SAWF-08P Air Quality Monitor is the more open pick between these two.
It commissions natively over Matter into Apple Home, Alexa, Google Home, SmartThings and Home Assistant, adds a built-in display, and holds a higher owner rating. The Amazon Smart Air Quality Monitor claws back ground on sensor variety, tracking TVOC, PM2.5 particulates and carbon monoxide alongside temperature and humidity, five readings against the SONOFF's three, and it can trigger Alexa routines directly from its own readings with no hub. But it is genuinely useless without an Echo device: no Google Home, Apple Home, SmartThings or Matter support at all. Alexa households wanting a broader pollutant picture should stick with the Amazon monitor; anyone on another platform, or who just wants a straightforward CO2 reading, should pick the SONOFF.

What the differences mean
Platform lock-in
The Amazon monitor works only with Alexa, with no Google Home, Apple Home, SmartThings or Matter path at all. The SONOFF's native Matter reaches all of those plus Home Assistant with no hub.
Sensor variety
The Amazon monitor measures five things: TVOC, PM2.5, carbon monoxide, temperature and humidity. The SONOFF measures three: CO2, temperature and humidity, with no VOC, particulate or CO sensing.
Display
The SONOFF shows its readings on a permanent LCD panel. The Amazon monitor has no screen at all; every reading lives in the Alexa app or a voice request.
Automations
The Amazon monitor can trigger Alexa routines directly from temperature, humidity, CO, particulate or VOC readings with no separate hub. The SONOFF's automations run through whichever Matter controller you use instead.
Connectivity
The Amazon monitor connects over Wi-Fi and Bluetooth for setup. The SONOFF uses 2.4 GHz Wi-Fi only, which is what its native Matter support runs over.
Which one to buy if
- you're an Alexa household wanting a wider pollutant picture
It tracks TVOC, PM2.5 and carbon monoxide, none of which the SONOFF measures.
- you're not on Alexa, or want to switch platforms later
Native Matter reaches Apple Home, Google Home and SmartThings; the Amazon monitor works only with Alexa.
- you want a number visible without asking a voice assistant
Its permanent LCD shows the reading directly; the Amazon monitor has no screen at all.
- you want routines triggered straight from air readings with no hub
It can fire Alexa routines from CO, VOC or particulate levels directly, which the SONOFF's Matter setup doesn't do the same way.

What owners say
Owners of both monitors describe getting a first reading within minutes of unboxing. What they value beyond that splits sharply by ecosystem. Amazon Smart Air Quality Monitor owners like triggering Alexa routines straight from a reading, no hub required, and several credit it with catching a genuine hazard like a leaking generator, though the Alexa app itself draws criticism for weak data views and no export. SONOFF SAWF-08P Air Quality Monitor owners praise the always-visible display and how easily it commissions into a Matter network spanning several platforms, while some note it has no manual calibration and reads only CO2, missing the particulate and VOC sensing the Amazon device offers.
