Not NDIR CO2
Device does not appear to be NDIR CO2 a claimed, but the much cheaper e-CO2 type that is estimated from the VOC measurement. The CO2 reading follows the VOC reading when exposed to ethanol vapor. This is a good test for a CO2 meter as an NDIR sensor will not respond to ethanol Not worth the extra money. I returned the meter.

Random Numbers?..
I returned this item. I had few other devices to compare the air quality values, such as an Airthings and Ecobee.I became suspect of this device in the first two days because it always displayed between 60-63% humidity one hundred percent of the time. I have wood floors, art, books and manuscripts and there is no way the humidity would be at that level 100% of the time without me having a panic attack.The carbon dioxide levels also didn’t match my other devices, not did it rise when I turned on my gas stove as would be expected if it worked properly. This was a huge deal breaker. Ultimately, I couldn’t trust the health of my home to this air quality device.The display is easy to read, but also a teeny bit distracting and annoying.
