random fan speed in auto mode

I have two Big and Quiet purifiers.

the fan speed when in Auto seems to be very random and not related to AQI. When both have similar AQI (15- 20) one will be on max fan speed and the other on low (2-3). They seem to be stuck on those fan speeds and don’t change. 
Why is it not more predictably the speed is and why does the speed not reduce from 10 when the AQI has been stable around 16 for some time?
