Here are all the available and not IAQ Monitors on the market. This time I included a new row with the Year each device became or will become available.
A PDF version of the table is available here: Comparison AIQ 2018 Q4
- 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 IAQ Monitors and Air Purifiers Combo. On this list you can only read the features as an IAQ monitor.

looks interesting with lots of possibilities and options but for example no NO and NO2 which is a shame

Would you mind posting this chart in Excel or whatever is the original format? The PDF is really hard to digest, and would be great to filter (e.g., show me only things with the feature I want). A Google Sheet (set to “anyone with the link can View only”) would be ideal.

For the moment, there is a huge test going on with sensors, tested by Belgian and Dutch EPA’s. We notice that a lot of sensors just can’t keep up next to reference monitors, they score way under 15% margin or just display strange behaviour.. Last one on the test bench was the uhoo, results were just bad.As usual, cheap iaq monitors are just gimmicks. I hope to get all test results and will share it.
