The Amazon Smart Air Quality Monitor measures PM2.5, VOCs, CO, humidity, and temperature to provide an indoor air quality score. PCMag called it 'fairly limited in terms of functionality' but noted it 'easily alerts you to pollutants and other gaseous impurities.' The device integrates with Alexa for notifications and voice control, and offers comprehensive air quality graphs. However, it doesn't purify air and lacks measurement of CO2 and radon, which some reviewers noted as significant limitations. This monitor is best for users seeking basic air quality awareness rather than comprehensive air purification solutions.

Strengths
  • Measures PM2.5, VOCs, CO, humidity, and temperature
  • Provides hourly, daily, and weekly air quality graphs
  • Indicator light shows current air quality at a glance
Watch-outs
  • Does not purify the air
  • Only measures PM2.5, not PM10 particles
  • Does not measure CO2 or radon gases

Atmotube PRO 2

The Atmotube Pro 2 represents a significant upgrade over its predecessor, adding a carbon dioxide sensor and improving sensor accuracy. Reviewers noted the device's ability to measure PM2.5, NOx, and TVOC with high correlation to reference standards, though some users reported issues with CO2 calibration. The inclusion of GPS and USB-C data access enhances its utility for field research and personal monitoring. While the device excels in outdoor exposure tracking and data collection, the carbon dioxide sensor's reliability remains a concern for some users. This monitor is ideal for researchers and health-conscious individuals seeking comprehensive air quality data but may not be suitable for those requiring highly accurate CO2 measurements.

Strengths
  • Includes carbon dioxide sensor (Sensirion STCC4) for indoor air quality monitoring
  • Upgraded PM sensor (Sensirion SPS30) provides accurate particle concentration measurements
  • Built-in GPS and accelerometer enable location-aware data collection without excessive battery drain
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

How they stack up

Amazon Smart Air Quality Monitor – Know your air, Works with Alexa

The Amazon Smart Air Quality Monitor provides basic air quality awareness with PM2.5, VOCs, CO, humidity, and temperature measurements, but it lacks CO2 and radon detection that other models like the Airthings 2960 View Plus offer. While it integrates well with Alexa, its limited sensor range makes it less comprehensive compared to the Atmotube PRO 2, which provides more detailed particle measurements and GPS tracking.

Atmotube PRO 2

The Atmotube PRO 2 provides improved PM sensor accuracy and GPS tracking, 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.
