Expert Verdict

The SONOFF SAWF-08P AirGuard CO2 monitor offers Matter-native multi-ecosystem compatibility (Apple Home, Home Assistant, Google Home, SmartThings) with a 3.73-inch LCD and USB-C power, but suffers from a utilitarian design lacking screen backlight and inconsistent Alexa integration. Good for budget air quality monitoring in Matter-based smart homes under $50.

Best For

Users with Matter-based smart home ecosystems who need affordable CO2 or PM2.5 monitoring should buy this.

Avoid If

Those reliant on Alexa integration or wanting a premium design with backlit display should avoid.
