Ranked #4 in Best Air Quality Monitors

Awair Element

3.9

$209

The Awair Element is praised for its elegant design and reliable performance as an air quality monitor. Trusted Review called it 'simple, reliable, and above all, elegant,' while CleanAir Community noted its 'best-looking' appearance and good responsiveness to pollution sources. However, some reviewers questioned the sensor accuracy, particularly the CO2 sensor which has a stated accuracy of ±75ppm or 10%—considered less precise than expected for its price. The device is recommended for those seeking a straightforward, visually appealing air quality monitoring solution, though users looking for maximum accuracy may want to consider alternatives.

Strengths

— Equipped with five built-in sensors measuring temperature, humidity, CO2, TVOCs, and PM2.5
— Provides accurate PM2.5 readings with ±13.68% deviation in testing
— Intuitive setup process with seamless Wi-Fi connectivity

Watch-outs

— CO2 sensor accuracy of ±75ppm or 10% (whichever is greater) considered subpar for its price point
— Some sensors have limited lifespan, with one user reporting a short-lived PM sensor

Higher ratedRanked #1 in Best Air Quality Monitors

Qingping Air Quality Monitor Gen 2

4.6

$149

The Qingping Air Quality Monitor Gen 2 is praised for its accurate sensors, including a high-quality Sensirion SCD40 CO2 sensor and replaceable PM2.5 sensor, making it one of the top performers in its class. Reviewers noted its ability to display multiple air quality metrics and compatibility with both Qingping+ and Mi Home apps. However, the device suffers from poor battery life and connectivity issues with the app, which can make it frustrating to use. It's best suited for users who prioritize accuracy and sensor quality over battery longevity and app reliability.

Strengths

— Uses high-quality Sensirion SCD40 NDIR CO2 sensor with accuracy of ±(50 ppm + 5% of reading)
— Displays seven data points including PM2.5, PM10, CO2, eTVOC, temperature, humidity, and noise level
— Features replaceable PM2.5 sensor for easy maintenance without replacing the entire device

Watch-outs

— Poor battery life lasting only up to 4 hours, often much less
— Connectivity issues with the app including long wait times and firmware update failures

How they stack up

Awair Element

The Awair Element provides a visually appealing design and good PM2.5 accuracy, but its CO2 sensor accuracy of ±75ppm is significantly worse than the Qingping Gen 2's Sensirion SCD40 sensor, which offers ±(50 ppm + 5% of reading) accuracy. While it's easier to set up than the Atmotube PRO 2, which has calibration issues, the Awair Element's CO2 accuracy makes it less suitable for users needing precise carbon dioxide measurements.

Qingping Air Quality Monitor Gen 2

The Qingping Gen 2 features the high-quality Sensirion SCD40 CO2 sensor, which outperforms the CO2 accuracy of the Awair Element and Atmotube PRO 2, but it suffers from poor battery life compared to the Temtop M10, which offers up to 6 hours of battery operation. While it provides replaceable sensors, the app connectivity issues make it less reliable than the AirGradient One, which offers seamless integration and better overall user experience.
