220ml Diffusers from cocod'or will last up to 6 months. Longevity depends on many factors such as:
-Number of reed sticks used.
-Using the White Flower stick make the fragrance stronger and increases consumption.
-How often are reed sticks flipped. i.e ever couple of days, every week or month.
-Diffuser location i.e. If a diffuser is placed in direct sunlight it will be much stronger therefore consumed quicker.
-Room area i.e. Large spaces require larger volumes to help spread the scent efficiently and to make sure you can smell it everywhere in the room. Diffusers release more fragrance to saturate the surroundings with the scent.
