Holidays are coming and people are searching for gifts or for ways to protect themselves from air pollution. A great way to start 2018 is by seeing the air around you. Once more new companies offer more choices to the costumers and the old ones offer mature products through solid updates. On this update I have removed the Design row and I have added the Application Programming Interface API row, for those who want to know if the companies support this feature. Click on the image and download the PDF document.
- 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.

Thanks for assembling all these product specs in these quarterly review posts; they’re very useful for comparison shopping. Where on your blog can I find your thoughts on the *accuracy* of the sensors of these products? I’m mostly interested in measuring PM2.5 and PM10 indoors reliably and cheaply, and am not interested in fancy user interface stuff. (For example, this simple & affordable monitor from IGERESS — https://www.amazon.com/Detector-Accurate-Formaldehyde-Detection-IGERESS/dp/B071LB8MPZ — but I can’t find any information about the quality of their sensors.)

Hi Daniel, thank you for kind words.
If you are intrested on cheap but good PM Sesnor I would recomend you two of the DIY monitors. https://seetheair.wordpress.com/2017/10/16/diy-pm-monitor-take-2/ and https://seetheair.wordpress.com/2017/07/25/ok-lab-stuttgart-pm-diy-monitor/
Now, regarding the link you sent me this device is availabe for 60euros from Aliexpress. I don’t know a lot about it and it is hard to find a datasheet. I have sent an email to ask for details, lets hope they will answer. Here is what I found so far: https://seetheair.files.wordpress.com/2017/11/wp6912.pdf
Note that from my conversation with uHoo there’s no individual-access API.
You are welcome.
About uHoo, they told me that currently there isn’t consumer API but it will be released sometime in 2018.
AirVisual now belongs to IQAir, AirVisual Node removed from sale 😦
Available AirVisual Pro (269$)
What is the difference between models don’t know, company say “The name just changed from Node to Pro. The Pro gets a few extra features, further improved sensor, shinier screen, etc.”

Hi Victor, Although I have asked them if there is any hardware change on the Pro version, they haven’t answered me yet. My personal opinion is that there isn’t any change.
I finally have some news of the new AirVisual Pro version so here are some of the main improvements over the previous version:
– Enhanced calibration of the PM2.5 sensor making it by far the most accurate PM2.5 sensor on the market in this product category. PM10 logs are stored on the device too.
– Silent fan and 0 vibrations for the PM2.5 sensor
– Wi-Fi off feature for people who don’t want to receive Wi-Fi radio waves
– Custom set up of measurement periods (every 5 minutes, 10, etc.)
