Ranked #3 in Best Air Quality Monitors

Atmotube PRO 2

4.0

1 source$159as of Oct 10

The Atmotube Pro 2 is a meaningful step up from its predecessor, adding a carbon dioxide sensor and sharpening sensor accuracy. Reviewers noted it measures PM2.5, NOx, and TVOC with high correlation to reference standards, though some users reported problems with CO2 calibration. GPS and USB-C data access make it more useful for field research and personal monitoring. It does well on outdoor exposure tracking and data collection, while the carbon dioxide sensor's reliability remains a concern for some users. Researchers and health-conscious individuals who want comprehensive air quality data are the fit, but anyone who requires highly accurate CO2 measurements should look elsewhere.

Strengths

— Includes carbon dioxide sensor (Sensirion STCC4) for indoor air quality monitoring
— Built-in GPS and accelerometer enable location-aware data collection without excessive battery drain
— USB-C port allows direct data access and sync across multiple devices

Watch-outs

— Carbon dioxide measurements have reported systematic calibration issues
— Initial CO2 readings required manual adjustment to align with reference standards
— Some users experienced inconsistent performance with CO2 sensor accuracy

Higher ratedRanked #2 in Best Air Quality Monitors

Awair Element

4.5

1 source$254as of Sep 25

The Awair Element gets credit for elegant design and reliable performance as an air quality monitor. Trusted Review called it 'simple, reliable, and above all, elegant,' and CleanAir Community named it the 'best-looking' unit while noting good responsiveness to pollution sources. Sensor accuracy drew questions, particularly the CO2 sensor's stated ±75ppm or 10%, which reviewers considered less precise than the price suggests. Buyers who want a straightforward, visually appealing air quality monitor are the fit; anyone chasing maximum accuracy may want to consider alternatives.

Strengths

— Equipped with five built-in sensors measuring temperature, humidity, CO2, TVOCs, and PM2.5, per Air Purifier First
— Air Purifier First found accurate PM2.5 readings with ±13.68% deviation
— Intuitive setup process with seamless Wi-Fi connectivity, according to Air Purifier First

Watch-outs

— Some sensors have limited lifespan, with one user reporting a short-lived PM sensor

How they stack up

Atmotube PRO 2

The Atmotube PRO 2 adds GPS tracking while keeping the same Sensirion SPS30 PM sensor as its predecessor, but its CO2 sensor has reported calibration issues that make it less reliable than the Qingping Gen 2, which offers consistent Sensirion sensor performance. While it's better suited for field research than the Awair Element, which lacks GPS capabilities, the Atmotube PRO 2's CO2 accuracy problems make it less ideal for users requiring precise carbon dioxide monitoring.

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.
