Ranked #6 in Best Air Quality Monitors

$69

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

Qingping Air Quality Monitor Gen 2
$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

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.

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.
