Is a nitrogen dioxide (NO2) sensor installed in the device? How quickly does the automatic mode react to detected pollutants (if at all)?

Helpful answer
The air purifier does not have a specific nitrogen dioxide (NO2) sensor. However, it uses a double layer of activated carbon that can reduce nitrogen dioxide. The automatic mode reacts quickly to detected pollutants, as the sensors analyse the air quality 1,000 times per second and adjust the purification stages accordingly.
