Hi there! I was wondering how long the reed diffusers typically last before you need to buy an oil refill?
Thank you for your question.
VOYA recommends that the diffuser oil is changed every 4 to 6 weeks. However, this would also depend on the position of the diffuser, for example, if it is placed in a very open space, in direct sunlight or near a radiator or heating device, then the oil may need to be changed on a more regular basis. We would also suggest that users flip the reeds frequently to help diffuse and prolong the scent also.
