More and new devices on the market. From wearables to home AQI monitors are here to assist people’s needs. Remember air pollution is everywhere.

  • Prices may vary during time.
  • Some Companies don’t specify on their data sheet if their devices are capable to measure PM2.5 or PM10 and they just mention the word dust.
  • Some other companies say: Our product goes beyond CO₂ by analyzing substances that directly affect your well-being by measuring VOCs. They aren’t clear if their devices have CO₂ sensor.
  • Some of the devices are AQI Monitors and Air Purifiers Combo. On this list you can only read the features as an AQI monitor.
  • The classification of the design between BadGood and Very Good is based on the materials (plastic, wood, glass and metal) that they use and the aesthetic on my personal opinion.

  1. I wonder if someday you could include the type of sensor that is used. The technology behind the sensor (metal oxide, electrochemical, particle sensor…) would be an interesting category to help our understanding of these devices. You have touched on this in your comments and I agree that some devices may not clearly state what sensors they are using.

  2. Thanks for including Speck! A couple minor corrections for Speck:

    * We offer 2 models, one with a humidity sensor ($199), and one without ($149). Your chart says “No” for humidity, which is fine if that’s the model you tested, but then the price should be listed as $149 and not $200. Alternatively, change “Humidity” to “Yes” and list the price as $199.

    * If by “Map/Share” you mean some sort of map showing all (public) Specks, then it should be listed as “Yes”. Our public data map is here:

    Finally, in response to Cheryl’s question about sensor used, we provide full tech specs here:
