The lifespan of an Aromely oil bottle varies and typically ranges between 1 to 3 months. This duration is influenced by several factors, including: Type of Diffuser: Different diffusers consume oil at varying rates. Intensity Settings: Higher intensity settings use more oil. Usage Frequency: Regular use for several hours a day will deplete the bottle faster. Given these variables, it's challenging to predict an exact timeframe. However, on average, users can anticipate their Aromely oil bottle to last anywhere from one to three months under normal usage conditions.
