Updated September 2026

Data from Amazon and official Airthings and Sonoff sites.

2026 verdict

Screen, price and platform reach put the SONOFF SAWF-08P Air Quality Monitor ahead of the Airthings Wave Plus in this air quality monitor matchup, even though the Airthings packs more into its sensor array.

Winner

SONOFF SAWF-08P Air Quality Monitor

$49.90

Buy on Amazon USA

The SONOFF shows CO2, temperature and humidity on a permanent LCD panel and reaches Apple Home, Alexa, Google Home, SmartThings and Home Assistant through native Matter, all for a lower price than the Airthings. The Airthings Wave Plus counters with six sensors instead of three, radon, TVOC and atmospheric pressure on top of CO2, temperature and humidity, plus its own SmartLink hub option for continuous data, but it has no screen at all (just a wave-activated status light), stays on Bluetooth unless you buy that hub, and skips Apple HomeKit, SmartThings and Matter. Both carry long warranties and a comparable owner rating. Pick the Wave Plus for the broadest sensor spread, including radon; pick the SONOFF for a readable, Matter-native monitor at a lower cost.

Frequently Asked Questions

Which is better overall: Airthings Wave Plus or SONOFF SAWF-08P Air Quality Monitor?

For most buyers, the SONOFF SAWF-08P Air Quality Monitor is the easier recommendation: it costs less, has a built-in display, and its native Matter support reaches Apple Home, Alexa, Google Home, SmartThings and Home Assistant. The Airthings Wave Plus senses far more, including radon, TVOC and atmospheric pressure, and is the better choice for anyone who specifically needs a multi-pollutant monitor rather than a display-and-platform focused one.

What is the biggest difference between the Airthings Wave Plus and the SONOFF SAWF-08P Air Quality Monitor?

Sensor count versus display and connectivity. The Airthings Wave Plus measures six things (radon, CO2, TVOC, temperature, humidity and atmospheric pressure) but has no screen and relies on Bluetooth, needing an optional Airthings Hub for continuous remote data. The SONOFF SAWF-08P Air Quality Monitor measures only CO2, temperature and humidity, but shows all three on an LCD screen and connects natively over Matter with no hub needed.

Does the Airthings Wave Plus measure radon?

Yes, radon is one of its six sensors, alongside CO2, TVOC, temperature, humidity and atmospheric pressure. The SONOFF SAWF-08P Air Quality Monitor does not measure radon at all, only CO2, temperature and humidity.

Which one works with more smart home platforms?

The SONOFF SAWF-08P Air Quality Monitor. Its native Matter over Wi-Fi support reaches Apple Home, Alexa, Google Home, Samsung SmartThings and Home Assistant with no hub. The Airthings Wave Plus works with Google Home, Alexa and Home Assistant, but has no Apple HomeKit, SmartThings or Matter support.

Who should buy the Airthings Wave Plus?

Choose the Airthings Wave Plus if you want one battery-powered device covering radon alongside CO2, TVOC, temperature, humidity and pressure, and you do not mind a screenless, wave-to-check design that syncs over Bluetooth (or add an Airthings Hub for continuous online data).

Who should buy the SONOFF SAWF-08P Air Quality Monitor?

Choose the SONOFF SAWF-08P Air Quality Monitor if you want an affordable, always-visible CO2 reading that plugs directly into a Matter smart home, whether that is Apple Home, Alexa, Google Home, SmartThings or Home Assistant, and you do not need radon or TVOC sensing.
