AirGuard vs SAWF-07P Spec Comparison
Target Pollutants
The SONOFF SAWF-07P monitors particulate matter, specifically PM2.5 and PM10 levels. It does not track gas concentrations. The SONOFF AirGuard SAWF-08P focuses entirely on carbon dioxide (CO2) using an NDIR sensor. You cannot use the SAWF-07P to check CO2, and the AirGuard cannot detect dust or smoke. If you need to monitor allergens or cooking particles, the SAWF-07P is the correct choice. If you want to track ventilation and air freshness based on CO2, the AirGuard is the right tool. They measure completely different aspects of indoor air quality.
Sensor Accuracy
The SAWF-07P provides high-accuracy readings for particulates, maintaining ±10μg/m³ for PM2.5 in the 0-100μg/m³ range. It also tracks temperature and humidity with ±1°F and ±3%RH precision. The AirGuard SAWF-08P uses an NDIR sensor for CO2, offering ±(50ppm + 5%) accuracy between 400-5000ppm. Both devices also monitor temperature and humidity. The SAWF-07P offers more granular particulate data, while the AirGuard provides specialized gas detection. Your choice depends on whether you prioritize dust levels or CO2 concentration for your specific health or comfort needs.
Refresh Rate
Data update speed differs between the two monitors. The SAWF-07P updates its display and app data every 2 seconds. This fast refresh rate allows you to see immediate changes in particulate levels, which is useful if you are actively cooking or cleaning. The AirGuard SAWF-08P updates every 5 seconds. While slightly slower, this interval is sufficient for tracking CO2 trends, which change gradually. For real-time particulate monitoring, the SAWF-07P is faster. For general CO2 awareness, the AirGuard’s speed is adequate. You should choose based on how quickly you need to see environmental shifts.
Alert System
Both devices notify you via app alerts and multi-color LED indicators. The SAWF-07P adds a sound prompt to its alert system. This audible warning can catch your attention even if you are not looking at the screen or your phone. The AirGuard SAWF-08P relies only on the LED and app notifications. If you prefer an audible alarm when air quality drops, the SAWF-07P offers this extra layer of notification. If silent operation is preferred, the AirGuard’s LED-only approach may be better. Both allow customizable thresholds in the eWeLink app.
Display Size
The SAWF-07P features a 3.73-inch screen. This larger display makes it easier to read PM2.5, PM10, temperature, and humidity values from a distance. The AirGuard SAWF-08P also has a screen, but the exact size is not specified in the provided data. The SAWF-07P’s larger panel ensures better visibility for all four metrics. If you place the device across the room, the SAWF-07P’s screen size gives you an advantage in readability. The AirGuard’s screen size remains unknown, so we cannot compare them directly on this specific metric.
Physical Dimensions
The SAWF-07P measures 4.72 inches in width, 5.51 inches in height, and 2.36 inches in length. It weighs 7.76 ounces. The AirGuard SAWF-08P is narrower, measuring 3.94 inches in width, with the same height and length. The AirGuard’s width is smaller, making it potentially easier to fit in tighter spaces. The SAWF-07P is slightly wider due to its larger screen and additional sensors. If countertop space is limited, the AirGuard’s narrower profile is the better fit. Both devices share the same height and depth, so vertical clearance is identical for both.
