How long does the diffuser work for?Updated 10 months ago

1 refill lasts up to 30 days. It is recommended to replace the refill every 4 weeks, even if there is a small amount of liquid left inside the vial (the vial can never be completely empty as the last drops of liquid are not in sufficient contact with the wick to allow diffusion to occur)

With continuous use, a diffuser lasts 6 months. Replace the diffuser after every six months of continuous use to ensure optimum effectiveness.
