My question relates to the minimum VOC that the BME680 can show. As I understand it, this value can be at least 0.3ppm (that is, 300ppb). In some sources, this value is already considered as lightly polluted air, while for the BME680 this is the minimum. Is there a quality classification for the VOC value (for example, as presented in the datasheet about the index for Air Quality (IAQ) in Table 4)?
I read this discussion and calculated that 0.5 ppm = approximately 0.9 mg / m3. And this value is not the best indicator of air quality. It is possible that the BME680 should have a different quality classification scale for the estimated VOC value.

There was BME680 IAQ classification table in data sheet, do you mean you want to know quality classification table about BME680?
Hi, thanks for the reply.
Yes, I mean such a similar classification, but for the VOC values that the BME680 shows. Working with the sensor, I noticed that its VOC values are significantly higher than other similar sensors (for example, SGP30).
Our company is now producing units with an SGP30 sensor inside, but for some reason we are looking for a replacement and paid attention to the BME680. The estimated values of CO2 and VOC equivalents are important to us.
