It runs a proper NDIR sensor, shows the number on a permanent display, and commissions natively over Matter into Apple Home, Alexa, Google Home, SmartThings and Home Assistant with no hub. The Airthings 2989 View Radon is the one to reach for if radon is actually the concern: it's the only device here that detects it at all, and its Wi-Fi plus Bluetooth connection enables remote alerts and weekly email reports the SONOFF cannot match. Both track temperature and humidity. Pick the View Radon for radon tracking with remote access; pick the SONOFF only if a CO2 reading with wide platform support is what you're actually after.

What the differences mean

What each one detects

The View Radon tracks radon plus temperature and humidity; the SAWF-08P has no radon sensor and instead reads CO2 continuously. Neither substitutes for the other.

Remote access

The View Radon's Wi-Fi and Bluetooth combination enables push alerts and weekly email reports from anywhere. The SAWF-08P has no equivalent remote reporting; its value is the number on its own display and its Matter reach.

Power

The View Radon runs on 6 AA batteries or USB-C, so it can go anywhere or stay plugged in. The SAWF-08P is USB-C only, with no battery option at all.

Smart home reach

The SAWF-08P's native Matter reaches Apple Home, Alexa, Google Home, SmartThings and Home Assistant with no hub. The View Radon works with Google Home, Alexa and Home Assistant, with no Apple Home, SmartThings or Matter support.

Which one to buy if

  • radon tracking with remote alerts matters
    Airthings 2989 View Radon

    Its Wi-Fi and Bluetooth connection sends alerts and weekly reports the SAWF-08P has no equivalent for.

  • you just want one CO2 number, wired into any smart home
    SONOFF SAWF-08P Air Quality Monitor

    Native Matter gets it into five platforms with no hub, at a much lower price.

  • you need battery-only placement, no outlet nearby
    Airthings 2989 View Radon

    It runs on 6 AA batteries; the SAWF-08P must stay plugged in over USB-C.

  • your platform is Apple Home or SmartThings
    SONOFF SAWF-08P Air Quality Monitor

    Its native Matter support reaches both; the View Radon has no path into either.

What owners say

Owners of both devices describe setup as fast, with neither needing more than a few minutes to get a first reading. What they value after that splits by what each one is built for. Airthings 2989 View Radon owners describe rotating the device between rooms and trusting the readings enough to confirm a mitigation fan is working, while some flag that support can be inconsistent when something goes wrong. SONOFF SAWF-08P Air Quality Monitor owners praise how easily it joins a Matter network with no bridge, though a handful mention the sensor has no manual calibration control and instead relies on fresh air exposure to reset its baseline.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
