A ScentPod 2.0 (65 ml) lasts on average 1 to 3 months in every Scentech diffuser. This depends on two things:
How many hours per day the diffuser is running
What intensity you've set it to
You choose the intensity in the app, from Low to Max. Based on your schedule and your setting, the app estimates how full your pod still is.
If you use the diffuser on average 12 hours a day at an average intensity, a scent lasts a good 2 months.
If you use a high intensity and have it on 16 hours a day, a scent still lasts at least 1 month.
In short: the more often and stronger you diffuse scent, the faster the bottle runs out, but even with intensive use, it lasts a long time.
