Is it not something specific to the manufacturer of your air purifier? Mine just has different coloured lights.
Fwiw when I was researching consumer grade air purifiers the consensus was that the VOC monitors on them are usually cheap and not that great, rather than use auto detect settings just put it on mid level and use a proper VOC detector to determine whether it’s all good. Or something…
To people with air purifiers, can anyone point me to a definition of the L1 L2 L3 L4 scale for the VOC gas detection…? Eg. L1 = 0-7, L2 = 8-12
