SONOFF AirGuard PM2.5/PM10 – SAWF-07P Matter Over Wi-Fi Air Quality Monitor

The SONOFF AirGuard PM2.5 & PM10 (SAWF-07P) is a Matter over Wi-Fi compatible air quality monitor that measures and displays real-time concentrations of PM2.5 and PM10 particulate matter. The device alerts users via visual signals and app notifications when levels exceed defined thresholds, helping to promote healthier indoor air quality through informed ventilation habits.

Thanks to Matter support, the AirGuard PM integrates seamlessly with Apple Home, Google Home, Amazon Alexa, and SmartThings ecosystems. The measured values can be used in smart automations – such as activating air purifiers, fans, or ventilation systems when particle levels rise.

Its minimalist design, portability, and USB-C power supply make it ideal for both home and office use. Real-time display and in-app charts provide comprehensive insight for long-term monitoring.

Particulate matter (PM) consists of tiny solid or liquid particles suspended in the air. These particles fall into categories based on size: PM10, PM2.5, and PM1 – representing particles with diameters less than 10, 2.5, and 1 micrometers respectively.
