Every Dr Scent diffuser works in cycles: it releases mist, pauses, then repeats. The intensity grade you choose sets how long each mist and pause lasts. A higher grade mists longer and pauses less, so the scent is stronger and the oil goes faster. Grade 7 (highlighted) is the setting we use for the bottle-life figures on our product pages.
